Validating Circular End-of-Life Strategies for Domestic Post-Consumer Materials in the Latin American Region: A Life Cycle Assessment Approach

This study examines the domestic solid waste management system in the LATAM region, using the city of Guayaquil in Ecuador as a case study. Through the life cycle assessment (LCA) methodology, the study compares domestic and external recycling processes, evaluating their effects on global warming potential, fossil resource scarcity, and terrestrial ecotoxicity. The results reveal that increasing recycling rates significantly reduces environmental impacts, with domestic recycling offering slightly higher environmental benefits than external options. A demographic analysis using machine learning techniques identifies distinct patterns of waste generation across different population clusters, highlighting the need for tailored waste management strategies. The study also emphasizes the importance of accurate local data and the integration of recycling initiatives with market realities, particularly in the light of policies mandating recycled content in products like PET bottles. A sensitivity analysis of the waste recovery indicator (WRI) demonstrates the potential for substantial environmental and economic benefits with higher recycling rates. The findings suggest that, to advance towards a circular economy, Latin American cities like Guayaquil must enhance their recycling infrastructure, refine waste management policies, and focus on demographic-specific strategies. This research contributes to the broader understanding of sustainable waste management in developing regions, offering insights for future policy and infrastructure development.

IDENTIFICATION OF PROBLEMS IN THE PROCESS OF FORMING AN EFFECTIVE REGIONAL MANAGEMENT SYSTEM IN UKRAINE

Introduction. Attention is focused on the activation of the waste processing process, the technical equipment of the functional elements of the regional waste management system, the use of foreign experience in the implementation of recycling capacities, which will make it possible to specify goals in the implementation of innovative tasks in this field. The reasons that led to the low level of development of the domestic sphere of waste management are singled out: ineffective environmental policy, insufficient financing of relevant measures, neglect of environmental requirements, lack of practical steps in the development of infrastructure of a utilization nature. The purpose of the article. The purpose of the article is to identify problems that occur in the process of forming a regional waste management system in Ukraine, which prevent the achievement of real results in the context of sustainable development of regions. In order to achieve the set goal, the task of determining: a) problems that occurred before the full-scale war of 2022 was solved; b) problems that were added in the conditions of martial law. Results. It is emphasized that the formation of an effective waste management system is an important component of qualitative changes (sustainable development) in the regions of Ukraine in the context of its European integration aspirations. The region was considered in the context of obligations to eliminate existing problems in the field of waste management and practical implementation of tasks defined in regional waste management plans. A number of problems that occur in the field of waste management at the regional level are highlighted. The legislative provision of the waste management system and its influence on the achievement of expected results in this field are analyzed. The capabilities of local authorities in developing infrastructure for waste processing are substantiated. The treatment of waste in the conditions of martial law was studied. It was determined that within the limits of particularly dangerous territories there is a need to focus on the management of waste from destruction, on relatively safe ones - on household waste. The problems associated with the functioning of existing waste processing facilities due to the crisis situation in energy supply are singled out. Conclusions. It is noted that the identified problems are issues that need to be resolved, as threats arise behind them; these are tasks that should be solved in the context of the National Waste Management Strategy in Ukraine until 2030 with the aim of forming/developing the waste management system; these are the goals that must be resolved in the context of sustainable development and the development of a cyclical economy.

Using Material Flow Analysis (MFA) for Waste Management Planning in Batang Regency

The population of Batang Regency in 2021 reached 810,393 people, which has increased from the previous year. The increase in population results in an increase in the amount of waste generated in each region. However, Batang Regency only has Randukuning landfill as the only waste final processing site in this regency. The condition of the Randukuning landfill based on existing conditions during field surveys still uses the open dumping method with no massive reduction before the waste goes to the landfill. This condition is a separate consideration for planning waste management for good waste management in Batang Regency. In this waste management planning, the development of waste technology can also be used as a solution to how to manage waste effectively and efficiently. One way to determine the technology to be used is to use the Material Flow Analysis (MFA) method. This MFA method is a method that uses STAN software to determine the critical flow of the Batang Regency regional waste management system by paying attention to the results of the incoming input in the form of waste and the processes that occur so that later it will cause output how much and what or it can be said to know the scene in the field.

Technical and technological capacity of waste disposal in the regions of Ukraine

Active processing – incineration and utilization (mechanical and biological treatment), along with passive storage of inert residues in specially designated areas, are the most commonly used waste management techniques in Ukraine. According to European standards, these technologies carry environmental risks to some extent and do not belong to full-fledged recycling. Significant amounts of accumulated and generated waste determine the regional economic capacity that can be used for the introduction of recycling technologies. The article aims to conduct a feasibility study on waste processing in Ukraine, given the regional capacity for the development of recycling technologies. To reach this goal, the following tasks were solved: to analyze the existing technologies for processing household and similar waste and to carry out their economic evaluation; identify areas for innovative development of regional waste management systems in the near future. The analysis of technologies of household and similar waste processing existing in Ukraine is carried out. The article emphasizes that there are a number of problems with their functionality. Emphasis is placed on the availability of powerful raw materials for recycling. The following main problems of waste disposal sites are outlined: lack of their certification due to non-compliance with current standards and continued accumulation of waste despite the exhaustion of service life; voluntary decisions to close technogenic risk landfills; finding alternative ways of waste management. A comparative ecological and economic assessment of waste processing technologies is carried out. The use of innovative technologies of waste incineration through reconstruction and equipping of processing plants with modern combustion and filtration systems of exhaust gases to minimize environmental risks is relevant for the development of waste management systems.

ANALYSIS OF THE CORRESPONDENCE OF THE ROAD NETWORK OF THE OPISHNIAN TERRITORIAL COMMUNITY TO THE DEVELOPMENT TENDENCIES OF THE WASTE MANAGEMENT SYSTEM IN THE REGION

Planning of effective waste management systems at the level of territorial communities is an important practical task that ensures the implementation of the overall regional concept of the development of the regional waste management system. This process is based, first of all, on the study of the scientific and practical foundations of forecasting trends in the development of waste management systems, and especially their logistical component, taking into account the specifics of regional factors. Thus, there is a need to conduct an analysis of the technical-logistic component of the waste management system of individual territorial communities and its development prospects as a component of the regional waste management system of the Poltava region within the framework of solving the current scientific and practical task of ensuring the effectiveness of the implementation of the regional waste management system. Methodology. When studying the structure and technological parameters of the elements of the road network included in the project routes of solid waste transportation, the methods of system and factor analysis were used. Results. It has been established that the road network of Opishnyan TРЎ is simultaneously an element of the logistics structure of the waste management system at the local and regional level and is involved in all stages of solid waste transportation during various periods of implementation of the Regional Waste Management Plan of the Poltava Region. All categories of roads are involved in the transport schemes. The roads of the fourth category and some roads of the 5th category are the most heavily loaded. Most roads of categories T, O, C are in unsatisfactory condition and need urgent repair. The capacity of the existing road network, if it is maintained in a satisfactory condition, provides the possibility of movement along the specified routes of both collection and transport garbage trucks. The maximum permissible speed of movement according to the parameter of categorization on all roads of the region corresponds to the technical parameters and design modes of movement of specialized transport. Originality. The technological possibilities, main problems and directions of improvement of the road network of Opishnyan TРЎ as a separate object of logistics planning and a structural component of the waste management system at the local and regional levels have been determined. Practical value. The technological possibilities, main problems and directions of improvement of the road network of Opishnyan TРЎ as a separate object of logistics planning and a structural component of the waste management system at the local and regional levels have been determined.

Bi-objective approach for designing a regional waste management system: A case study of Vojvodina (Serbia).

This article presents a bi-objective mixed-integer linear model for the waste management system design. Two types of facilities, landfills and transfer stations (TSs), are identified based on two objectives: minimising the total system's costs and the total negative impact of located facilities on end users as waste generators through a defined pollution decay function. Landfills and TSs are categorised as undesirable facilities due to associated environmental risks. In this article undesirability of a located facility is defined as a two-threshold linear decreasing function of the distance between the end users and the located facility. Also, we considered additional restrictions that no two selected landfills or TSs are within a pre-specified distance from each other, limiting the superimposed pollution generated in these facilities. The model performances are tested on a real-scale example for Vojvodina (Serbia). Results showed that the proposed model has potentials and can be beneficial for government organisations, local authorities and other organisations related to waste management issues.

Development of a regional solid waste management framework and its application to a prairie province in central Canada

• Waste collection and landfill siting are concurrently optimized at regional level. • Two original performance indicators, ACC and LMI, are proposed and implemented. • Road length is one of the most important optimization parameters in Saskatchewan. • Divisions that share provincial or international borders generally optimized better. • Indigenous communities in border sharing divisions need better landfill siting plan. Landfilling continues to be one of the most popular waste treatment methods in Canada or abroad. NIMBYism has forced waste facilities to be sited further from populated centers, meaning that increases in waste management efficiency result in considerable cost savings. Concurrent optimization of waste collection and disposal siting on a regional scale is of practical importance. This study combines collection route optimization and landfill siting using GIS methods to design a regional waste management system in Saskatchewan, Canada. Two original performance indicators are proposed based on route optimization and landfill siting, namely the accessibility (ACC) and Landfill Minimization Index (LMI). The result suggest that the accessibility was able to be improved by between 15.4 and 794.7%, and the optimization methods was always effective in providing higher resident accessibility. Improvements in the LMI yielded less improvement, ranging from -13.9% to +422.2%. Correlation analysis showed that road length is a key optimization parameter. This finding is important to Indigenous communities who suffer from a lack of intensified road network. Divisions that share provincial or international borders generally have higher improvements in ACC and LMI. Strategic placement of landfills and road networks are key to improve waste management system efficiency in Saskatchewan.

Life-cycle assessment for municipal waste management systems

One of the important tasks of the environmental policy of the Russian Federation is to implement an integrated regional waste management system through the active involvement of production and consumption waste in the economic turnover, the use of environmentally sound recycling methods, the solution of environmental problems related to waste management and resource conservation. Environmental assessment of the existing municipal waste management system is carried out by analyzing the environmental impact and alternative waste management scenarios in order to develop an integrated waste management system for Irkutsk region. Modelling of production and consumption waste flows and their potential impact on the environment was performed. The method of material flow analysis using STAN software was used to estimate the fractional composition of waste. The method of life cycle assessment (LCA) was used to determine the environmental indicators, using the EASETECH software package, which allows for creating various scenarios of environmental impacts, comparing them and choosing the most optimal and environmentally safe one. The modelling of alternative future waste management scenarios for Irkutsk Region showed that all alternatives can improve the current waste management system, which primarily involves landfilling in an uncontrolled landfill without environmental measures. Construction of a new landfill with gas disposal and leachate treatment is a significant improvement, and recycling of secondary raw materials can reduce the environmental pressure. From an environmental point of view, the current waste disposal system is not efficient. Uncontrolled landfill is the main impact on global warming. Although a new landfill could significantly reduce this impact, it is worth reconsidering the waste management systems paying more attention to recycling rather than to landfilling.

The aim of the study is to ensure the effectiveness of the waste management system in Poltava region for the long term of the Regional Waste Management Plan in Poltava region for 2030 (RPUV) by analyzing the prospects of the logistics organization of waste management. Methodology. This paper uses methods of factor analysis with the study of causal relationships of the impact of conceptual provisions of the regional waste management system and some organizational and technological factors of its formation, as well as methods of inductive logic in forecasting trends. Results. It is established that the main conceptual principles of development of the waste management system of Poltava region provide for the introduction of a multi-stage scheme of solid waste transportation. The compliance of the road network with the goals of the RPUV is analyzed and the main problems are identified. A detailed analysis of the quality of the road network of the region allowed to identify the roads that pose the greatest threat to the implementation of the RPUV. The main tendencies of development of the park of specialized transport equipment in different perspective periods of realization of the plan and at different stages of the organization of transportations are established. Prospects for transport support of the first stage of transportation are formulated depending on the degree of urbanization of settlements. Originality. Based on the analysis of regional features of the system of solid waste management, the most probable directions of development of the technological component of the logistics structure of the regional system of solid waste management have been identified. Practical value. The results of the study reduce the risks of the implementation of the Regional Waste Management Plan and increase the efficiency of the solid waste management system.

Process-Based Emission Modelling for Sustainability Assessment in Municipal Solid Waste Management: A Comparative Study

Developments in Municipal Solid Waste Management (MSWM) systems depend on socio-cultural, political, economic, and environmental issues. The ability to assess and evaluate the level and nature of these relationships plays a critical role in measuring the performance level vis-à-vis sustainability of waste management systems. The current criteria adopted for assessing waste management performance do not capture an accurate and comprehensive representation of MSWM scenarios from collection to disposal. Hence the methodologies do not accurately measure the level of impacts resulting from waste management systems or, indirectly, the environmental, economic, social, and cultural costs of MSWM. This research develops a waste management performance assessment protocol that captures all relevant components of waste management processes. The methodology is based on emission as the indicator of choice for assessing the performance of a city-wide or regional waste management system. The study developed a framework, Comprehensive Emission Quantification Model (CEQ-Model), for measuring the sustainability of the MSWM system hinged on process-based emission modelling. This framework incorporated aspects of the Intergovernmental Panel on Climate Change (IPCC) Guidelines and Life Cycle Thinking (LCT), framed using carefully selected MSWM scenarios in New Zealand. In a ranked cumulative emission quantification assessment of four Territorial Authorities (TA), the research determined the performance level of each TA relative to others. Auckland Council, with a total emission of 4.272x1012 KgCO2-e generated from disposing of 2,425,022 tonnes of waste, was the most unsustainable territory, followed by Rotorua District with total emission of 6.666x10 10 KgCO2-e from 45,000 tonnes of waste, and Waikato District with emission of 5.380x10 10 KgCO2-e from 29,796 tonnes. In comparison, the most sustainable TA is Opotiki District with total emission of 2.314x10 9 KgCO2-e from 1,450 tonnes of waste, giving emission per tonne of waste per year as 1.762 GgCO2-e, 1.806 GgCO2-e, 1.6 GgCO2-e, and 1.481 GgCO2-e for Auckland Council, Waikato District, Opotiki District, and Rotorua District respectively.

Textile waste generation in the Sakhalin Region: cluster approach of collection and processing

The authors consider the conceptual issues of creating an effective regional model of textile waste management in the Sakhalin region. An analytical review and analysis of the current situation on the handling of textile waste generated as a result of both human activity and in the process of production activities of enterprises and organizations has been carried out. About 300 thousand tons of municipal solid waste (MSW) are generated annually in the region. Almost the entire specified volume is subsequently placed on landfills of MSW, and only 0.24 % is disposed of or neutralized. Today, there is an acute problem of insufficient recycling, including textile waste, which is practically not involved in repeated economic turnover. This is due to both the lack of necessary infrastructure and specialized enterprises. Currently, there is no unified system of collection, processing and disposal of textile waste generated by the population and in production technological cycles on the territory of the Sakhalin region. The creation of a textile waste collection and treatment system in the region is hindered by the lack of reliable statistical information on the volumes of waste generation in municipal districts and urban districts. The peculiarity of the waste management system in the Sakhalin region is the insular nature of the territory (the region is located on islands), which determines the cluster approach in the formation of a waste collection and treatment system. The authors carried out an indicative (expert and regulatory) assessment of the volume of textile waste generation in the Sakhalin Region and proposed optimal ways to improve the territorial waste management scheme (including MSW) aimed at increasing the collection and processing of textile waste. The concept of reforming the territorial scheme of solid household waste management in the Sakhalin region is proposed, based on the use of a cluster approach and allowing to minimize environmental consequences by involving waste in economic turnover as secondary resources for developing territorial production complexes in the region. The division of the municipalities of the region into clusters with the allocation of zones of direct transportation, transshipment and local disposal of MSW will enable a differentiated approach to waste management.

ПОВЫШЕНИЕ ЭФФЕКТИВНОСТИ КАДРОВОГО ОБЕСПЕЧЕНИЯ РЕГИОНАЛЬ-НЫХ СИСТЕМ ОБРАЩЕНИЯ С ОТХОДА-МИ НА ОСНОВЕ ПРОФЕССИОНАЛЬНЫХ СТАНДАРТОВ

The article substantiates the relevance of improving the staffing of regional waste management systems. The authors identify the problems of the current state of the sphere of waste management in cities and offer ways to solve them based on changing the system of personnel training, taking into account newly introduced professional standards. The novelty of the approach lies in the definition of targets for the develop-ment and implementation of professional standards not only for specialists involved in the field of waste management, but also for employees involved in the process of waste management at enterprises and organiza-tions in various fields.

The Mediating Role of Policy-Related Factors in the Relationship between Practice of Waste Generation and Sustainable Construction Waste Minimisation: PLS-SEM

As the construction industry grows, it produces large volumes of construction waste, which has a tremendous environmental impact and generates public concern in the neighbouring towns. The construction industry generates a significant volume of waste and faces a challenge with poor construction waste minimisation in order to prevent adverse environmental and dumping impacts worldwide. In developing countries, regional waste management systems have increased problems. Environmental pollution (air, water, and soil) and human health issues are caused by waste produced in a country as a result of different cultural, social, and religious activities. Prior studies were reviewed to choose dimensions and items for the data gathering instrument. A pilot test was conducted to identify potential questionnaire adjustments, and hypotheses were tested using structural equation modelling (SEM). A total of 220 Malaysian construction professionals answered the survey, which yielded the results. Five hypotheses have direct correlations based on the findings, three of which have a significant effect. Furthermore, the findings reveal that policy-related factors mediate the relationship between improving factors and sustainable construction waste minimisation. In contrast, they did not mediate the relationship between current practices/generation and sustainable construction waste management. The established framework can help improve construction waste management and help achieve global sustainable development goals. The data reveal that adopting preventive plans to reduce construction waste is one of the most important aspects of enhancing profitability. This study could aid construction industry players in evaluating waste management components during the construction and design stages of a building project.

Formation of a Regional Strategy for Municipal Solid Waste Management Considering Greenhouse Gas Emissions

Currently, Russia is going through a global transformation in the field of waste management, which is mainly caused by the exhaustion of the capacities of existing landfills. The country’s goal is to reduce landfill and ensure 36 % recycling of all municipal solid waste (MSW) by 2024. Meanwhile, the discussion about the choice of disposal methods continues. We propose to look at the choice of the optimal MSW management strategy at the regional level through the prism of its total greenhouse gas (GHG) emissions. In this regard, the purpose of the article is to determine the total carbon footprint of the regional MSW management system in order to consider the “contribution” of each of the methods of waste management and make the considered criterion suitable for assessing the sustainability of the whole regional waste management system under various scenarios of its development. To achieve this goal, the methodology of the Intergovernmental Panel on Climate Change was used to assess the current situation in the field of MSW management in the Sverdlovsk region. Further, the study developed the conditions for three industry development scenarios (basic, inertial, innovative); substantiated the factors of direct and prevented GHG emissions; calculated GHG emissions from the MSW management sector in the Sverdlovsk region for 2023-2030 for each of the three scenarios. The calculations showed that, by 2030, the basic scenario (“as is”, business-as-usual) has the maximum carbon footprint of 1558.5 thousand tonnes of CO2-eq. The innovative scenario has minimum net emissions of 82.6 thousand tonnes of CO2-eq. by creating a full-fledged separate waste collection and recycling more waste. The findings can be useful in the formation of regional strategies for waste management, considering GHG emissions.

Інфраструктурне забезпечення регіонального управління відходами у контексті циркулярної економіки (на прикладі Харківської області)

The article proposes an integrated approach to assessing the development of a waste management system on the example of the Kharkiv region. This approach is based on the use of a complex of indicators that characterize the current state of functioning of this system from both the ecological and the economic points of view. Based on the results of the diagnostics, barriers, threats, and ecological principles of function of the regional waste management system are identified. As a result of the study, it is substantiated that in order to provide an effective infrastructural provision of waste management, it is advisable to introduce a logistics approach, the essence of which is to integrate the principles of transformation of the waste management system, priority directions of waste recycling in the face of the destruction of critical infrastructure objects, implementation of the reverse logistics algorithm, the main components of the organizational and economic mechanism (functions, methods, management instruments, information systems, digital, «green», and innovative technologies), financial instruments of green investment for the implementation of the regional waste management strategy in the Kharkiv region. The implementation of the proposed approach will facilitate the adoption of substantiated innovative decisions on the greening of logistics activities and ecological management; timely solution of problems on the management of reverse flows of production waste using the principles of green and reverse logistics; minimizing the negative impact on the environment by reducing the volume of waste generation, increasing the volume of processing and reuse of waste; effective implementation of circular economy models, transition to expanding the responsibility of producers; increasing the level of ecological safety of the region; achieving the goals of sustainable development of the regional economy. It is found that in order to improve the waste management system in the region, it is expedient to: introduce the latest technologies and equipment for the collection, sorting, transportation, processing and disposal of waste, taking into account best European practices; promoting the use of waste recycling as a secondary raw material on the basis of «green» investment; development of a financial mechanism for the use of public-private partnership based on attracting private investment and other extra-budgetary sources of financing in the field of waste management; creation of an appropriate logistics infrastructure (for example, a cluster structure as an organizational form of partnership) for waste management; development and implementation of instruments for economic stimulation of waste disposal; implementation of the concept of reverse logistics in the context of a circular economy.

Institutional component of the waste management system

The article argues that the term «management» is also used to denote the characteristics of organizational and administrative activities of executive authorities and local self-government and is defined as the process of planning, organization, motivation, and control necessary to formulate and achieve the system's goals. In this context, the following goals of waste management are specified: implementation of legislation, control over compliance with environmental safety requirements, ensuring the implementation of effective and comprehensive measures in the context of compliance with the hierarchy of waste, rational use of natural resources, achieving the coordination of state and public entities’ actions in waste management. The relevance of this issue for Ukraine is determined both by its integration into European structures and by the need to improve the waste management system, in particular at the regional level. The purpose of the article is to study the current state of domestic legislation on the powers of government entities in waste management and present the institutional component of regional waste management systems through the prism of an integrated approach to its functioning. The analysis of the features of the current institutional structure of waste management and the duties and powers of system participants defined by the legislation at the national and local levels is carried out. The entities in the field of waste management involved in public administration are structured. Attention is focused on entities that do not have powers but are endowed with responsibilities and rights in the waste management system. We are convinced that the inconsistency of hierarchical communications causes dissonance in the actions of system elements. Therefore, it is important to organize information interrelation, which in form and content will allow us to make coordinated management decisions at different levels in time and provide a synergistic effect. The basic unit in the waste management system is reasoned. It is a region that has sufficient managerial levers. The hierarchical structure of the Regional Waste Management System is presented. The competent authorities that make decisions and perform local control functions in waste management are considered, in particular the powers of local self-government bodies. The features of the waste management system in the regions of Ukraine are determined.

ЕКОНОМІКО-ПРАВОВІ ІНСТРУМЕНТИ ПІДВИЩЕННЯ ЕФЕКТИВНОСТІ ПОВОДЖЕННЯ З ВІДХОДАМИ НА ПОСТКОНФЛІКТНИХ ТЕРИТОРІЯХ

The main purpose of this research is to analyze the state and possibilities of application of economic and legal instruments for increasing efficiency of waste management in post-conflict areas and offer ways of their improvement taking into account regional features. On the example of Donetsk region, the article considers the current state and prospects of regional planning in the field of waste management in post-conflict territories. It is shown different features and elements of the new planning system in this field including the National Waste Management Strategy until 2030. Special attention is given to analysis of the Guidelines for the development of regional waste management plans, which were adopted in September 2021. This document does not take into account the peculiarities of post-conflict territories due to ongoing hostilities, as well as related problems and threats, which influence decision-making in the field of waste management. Based on this, it is necessary to reflect these peculiarities in sections of regional plan that cover the characteristics of region and the analysis of the current state of waste management system in region. Possibilities of industrial parks for waste recycling in post-conflict territories are considered. Studies indicate that industrial parks created on the new site (“greenfield”) have significant advantages over parks located in former industrial zones on the basis of existing infrastructure (“brownfield”). The latest novelties of the Law of Ukraine “On Amendments to the Law of Ukraine “On Industrial Parks” aimed at attracting investment in the industrial sector of the economy by introducing incentives in industrial parks” (entered into force on October 7, 2021) are also investigated. Offers to improve the legal framework for industrial parks for waste recycling in post-conflict territories are substantiated.

Geoecological and economic assessment of the municipal solid waste management system in the Kaluga region

The removal of solid household waste to landfills is the most commonly used method of solid waste disposal and an important source of environmental pollution. Physical, chemical and biochemical processes occur in the body of a solid waste dump, which overlap each other and form an artificial aquifer and biogas. This article provides a brief overview of the environmental problems associated with the practice of garbage disposal and the negative impact of the landfill on the environment. The data on the features of the functioning of the solid waste landfill in Kaluga, on the dynamics of waste generation and changes in their morphological composition are presented. The issues related to the economic problems of waste disposal are considered.

An Integrated Approach for the Assessment of Environmental Sustainability in Agro-Industrial Waste Management Practices: The Case of the Tequila Industry

Sustainable waste management is a key component needed to achieve multiple of the Sustainable Development Goals established by the United Nations for the year 2030. Such waste management can reduce the degradation of superficial water sources and can contribute to the sustainable and efficient use of resources. Due to their usually high nutrient and organic loads, agro-industrial wastes pose a threat to soil and water resources and are a major contributor to greenhouse gas generation. In this study, a novel approach was proposed to assess the environmental sustainability of vinasse management practices, integrating an extensive physicochemical characterization of tequila vinasses, a GIS-based weighted overlay analysis and a scenario analysis. Mathematical models were applied for the determination of discharged pollutants (nitrogen, phosphorus, BOD5), as well as greenhouse gas emissions. This methodology was applied to an environmental sustainability assessment of the management practices of tequila vinasses, which are one of the main waste streams generated by the agro-industry in the Mexican state of Jalisco and are one of the main contributors to organic and nutrient loads affecting the water quality of Jalisco’s superficial water sources. Through this integrated approach, critical regions for the management of tequila vinasses were determined and an extensive physicochemical characterization of tequila vinasses was performed and applied to assess the environmental sustainability of four management scenarios for tequila vinasses. These results can be used by decision-makers for the implementation of public policy and infrastructure for the improvement of local and regional waste management systems. Additionally, these data may be used to increase the environmental sustainability of the tequila industry. The proposed methodology has the potential to be applied to different waste-intensive regions as well as different organic waste streams for the assessment of the environmental sustainability of specific management practices considering the local and regional context.

The purpose of the work is to analyze the network and bandwidth of the Automobile Roads of the Poltava region in order to establish the possibility of planning regional waste management systems. Methodology. In this paper, methods of finding information using modern digital technologies, systematization and analytical processing of statistical information, as well as methods of inductive logic to establish the possibility of using the Internet resources in logistical planning processes. Results. Within the framework of the tasks of the Regional Waste Management Plan in the Poltava region by 2030, the main attention is focused on the analysis of the possibility of organizing all stages of transport provided by the plan. In this context, the structure of the road network of the region is analyzed, indicated possible ways of using roads of various categories (from local to national) to organize waste transportation at all stages of the logistics process (from collecting waste in areas of settlements to the main transportation of waste between objects of the regional structure of handling with waste. Possible technological complications and technical and economic consequences of unsatisfactory road surface in most rural areas of the region are observed. These variants of possible partial and priority solution to the problem of unsatisfactory state of roads with prospective planning of the development of the waste transportation system are characterized. state of road covering from Internet resources of state specialized institutions and organizations and specialized sites of non-governmental organizations. Originality. Regional Planning Process Systems of waste management and logistics schemes for collecting solid household waste as the main structural and technological elements of these systems for the regions of Ukraine are currently located at the stage of becoming. The use of operational and promising information from open source resources for the purpose of medium-term and long-term planning is currently practically not applicable, although it has certain prospects. Practical value. The results of the research will be used in the development of a regional waste management plan in the Poltava region by 2030.
