Comprehensive review of solid waste management strategies and disposal approaches

Solid waste management is a worldwide concern with substantial environmental, social, and economic ramifications. This review provides a complete assessment of solid waste management from an Indian viewpoint. It presents an overview of the current state, difficulties, and prospects in solid waste management, focusing on environmental sustainability and public health. The goal is to give a comprehensive overview of many approaches utilized to manage and reduce the expanding problem of solid waste. It examines a variety of waste management techniques, such as landfill disposal, recycling, composting, waste-to-energy practices, and waste elimination and minimizing. Many municipalities across the country prefer landfilling for the removal of solid waste. In landfills, waste is transformed through chemical, biological, and physical processes, functioning as an environmental furnace. Therefore, soil cover thickness, barriers, leachate collecting, landfill gas recovery, and flaring facilities are essential for sustainable landfilling. The benefits of composting and anaerobic breakdown for decreasing the environmental effect of biological waste are examined in this review. Hazardous chemicals in landfills can have severe ecological and public health consequences. It looks into the benefits of effective dangerous waste disposal, such as pollution control and resource recovery. Mining and reusing landfills for diverse uses, such as renewable energy generation and recreational areas, have the potential to be beneficial. The article discusses upcoming solid waste management trends and technologies such as intelligent garbage collection mechanisms, reuse and recycling concepts, and sustainable packaging solutions. It emphasizes the potential of these advances to improve overall waste management effectiveness and sustainability.

Evolution of COVID-19 municipal solid waste disposal behaviors using epidemiology-based periods defined by World Health Organization guidelines

This study aims to identify the effects of continued COVID-19 transmission on waste management trends in a Canadian capital city, using pandemic periods defined from epidemiology and the WHO guidelines. Trends are detected using both regression and Mann-Kendall tests. The proposed analytical method is jurisdictionally comparable and does not rely on administrative measures. A reduction of 190.30 tonnes/week in average residential waste collection is observed in the Group II period. COVID-19 virulence negatively correlated with residential waste generation. Data variability in average collection rates during the Group II period increased (SD=228.73 tonnes/week). A slightly lower COVID-19 induced Waste Disposal Variability (CWDW) of 0.63 was observed in the Group II period. Increasing residential waste collection trends during Group II are observed from both regression (b = +1.6) and the MK test (z = +5.0). Both trend analyses reveal a decreasing CWDV trend during the Group I period, indicating higher diversion activities. Decreasing CWDV trends are also observed during the Group II period, probably due to the implementation of new waste programs. The use of pandemic periods derived from epidemiology helps us to better understand the effect of COVID-19 on waste generation and disposal behaviors, allowing us to better compare results in regions with different socio-economic affluences.

Leading the World: A Review of Household Recycling in Wales

Wales is one of the world leaders in household waste recycling with a steady recent recycling rate of ~65%. The Welsh Assembly Government (WAG) set a statutory target of achieving a 70% recycling rate by 2024/25. We reviewed historical trends in waste management in Wales from 2006 to 2020, with a focus on recycling. Authoritative, official data were obtained from WasteDataFlow, an Internet system for municipal waste data reporting by UK local authorities to government. Data are collected quarterly allowing the generation of time series plots, trendlines and like-for-like comparisons between groupings of various characteristics, such as number of separate kerbside collections, income, political preference, and impact of policy changes. Results showed that the approach taken by the WAG to politically prioritise and encourage participation in household recycling has achieved impressive results that contrast starkly with the recycling performance of other UK countries. In Wales, household waste disposed annually per person via landfill decreased from ~410 kg to <50 kg and household waste recycled increased from to ~150 kg to ~310 kg, with a recent increase in incineration with energy recovery to ~135 kg as infrastructure has come online. Recycling rates show a seasonal variation due to increases in garden waste sent for composting in the summer. There are variations in local authority performance across Wales, mainly caused by variations in the number of separate collections. Co-mingled collections tend to lead to higher contamination of recyclates that are then not able to be sold for recycling. Deprivation, as indicated by differences in income, also influences total waste arisings and recycling rates. A plateau of ~65% recycling rate was reached in 2020, with incineration reaching a rate of >25%. The recycling rate plateaus at exactly the same time as incineration comes on stream. Evidence demonstrates that improvements to recycling rates can become more difficult when incineration becomes available. Whilst further reductions and improvements to recycling in Wales will be more challenging, the WAG’s track record of focused proactive political and policy support shows what can be achieved when there is suitable political will. The WAG has demonstrated that it tends to deliver on its waste-related plans, and it clearly has the best chance of any of the UK’s four countries of achieving its aims.

Modeling And Simulation Of Plastic Wastes Generation For Operational Planning And Management In The Bonaberi Industrial Region, Cameroon

A review of waste management literature in use today shows that new techniques are needed in the process of planning strategic goals and objectives to technical goals and objectives. One of these techniques is the method which involves the modeling and simulation of wastes generated in our communities. This study uses the ARIMA (Autoregressive Integrated Moving Average), model to model and simulates plastic wastes generated in the Bonaberi industrial zone, of Cameroon for operational planning and management. Attention was also paid to their composition and uses as important resources for recycling industries. The monthly municipal plastic waste data from 2014 to 2020 was used to create a parsimonious ARIMA model. Different performance measures such as mean absolute deviation (MAD), mean absolute percentage error (MAPE), root mean square error (RMSE) and coefficient of determination (R-squared) were used to evaluate the performance of these models. Following this, ARIMA (1, 1, 1) model showed a superior prediction performance. According to this model, if current production and waste management trends continue, approximately 5468 Kg/month, 95% CI (2843, 9581) could be attained by December 2021.The results contribute to the process of planning strategic goals and objectives to technical goals and objectives in the region. The model developed can help decision-makers to take better measures and develop policies regarding waste management practices in the future. However, technical, environmental, and socio-economic feasibility studies to explore the technical options available, and to determine the factors that are considered important for the economic success of the project, and causing significant environmental problems resulting from improper disposal, namely burning or dumping, could also direct future investors in the region.

Study of porous rubber pipes reinforced with waste tire fiber and pineapple leaf fiber for smart irrigation system

Global trend in waste management involves sustainable development for waste utilization according to the concept of circular economy. Wastes from worn-out tires have been known as a world problem and not yet to be resolved successfully. In this work, wastes from worn-out tires, i.e., ground tire rubber (GTR), reclaimed rubber (RR) and waste tire fiber (WTF) were used to produce reinforced porous rubber pipes as irrigation system for smart farming. Comparative study of porous rubber pipes reinforced with natural fibers (pineapple leaf fiber, PALF) was also carried out. The experiment was divided into 2 parts, i.e., porous sheets (model study) and extruded porous pipes. Compound samples were prepared by mixing GTR, RR, and natural rubber (NR) at a ratio of 60:20:20 (by weight) with other additives by using an internal mixer, then shaped into samples by using a compression molding machine (sheets) and a single-screw extruder (pipes). Samples were vulcanized by a hot air oven. Factors affecting sample properties were studied, such as, fiber types (WTF and PALF) and fiber loadings (0-15 phr). Properties of the samples were characterized, such as, mechanical properties, morphology, water permeability rate, and %diameter swell. It was found that tensile strength was increased up to an optimum point. Modulus (at 10% strain, M10) and hardness were increased with increasing fiber loading. However, %elongation at break had a trend to decrease. Morphologies of the composites made from both fibers were insignificantly different in fiber distribution. By adding the fibers, %diameter swell was clearly improved. Pipe samples were also tested in precision smart agriculture system. It can be proven that WTF and PALF can be used to reinforce the porous pipes and used as a watering device for precision irrigation system.

Waste utilization market in the regions of Ukraine: current state analysis and main development trends

Modern development trends in waste management in the Ukrainian regions indicate the narrowing of the potential for waste processing and consolidation of the practice of their removal both in specially designated places and unauthorized spontaneous landfills. Unlike the EU countries, where the secondary processing of a significant part of the generated waste is carried out, a low level of waste utilization and processing is observed in Ukraine due to the limited development of processing. Despite the declared priority of the waste management problem, a certain improvement of the legal framework, and the implementation of state and regional profile target programs, the total amount of waste accumulated during operation continues to grow. The existing regulatory and legal gaps in waste management in Ukraine do not allow efficient implementation and achievement of the requirements for the functioning of this field declared at the national and regional levels. A change in the conceptual approach of state and local authorities in waste management from the dominance of waste disposal to prevention and reduction of waste generation and expansion of the practice of sorting, recycling, and use of energy and secondary material resources is the key to achieving the positive changes in solving these problems in Ukraine. Within the framework of the EU-Ukraine Association Agreement, Ukraine undertook obligations related to the harmonization of its legislation in waste and secondary resources management with the EU legislation. These obligations stimulate it to reform this area in accordance with modern norms and standards based on the principles of circular economy and resource and energy conservation. The article establishes that the current state of the waste utilization and processing market in Ukraine depends on the development and support level of entrepreneurial initiatives in this area, as well as the interest of regional authorities and specialized communal organizations in strengthening and expanding their own resource potential. According to the analysis of the waste utilization and processing market in Ukraine, three main groups of barriers that prevent its development are identified. A list of priority profile tasks, the consistent implementation of which will allow overcoming these obstacles and creating favorable conditions to boost the recycling market development in Ukraine in the near future, is proposed.

Strategic Potential of Agricultural Waste as a Feedstock for Biofuels Production in Ukraine

Abstract Ukraine’s agriculture is a leading sector of the national economy. Ukraine has a significant area (603628 km2), 70.9% of which are agricultural lands. Quality soil and good climatic conditions create favorable conditions for the development of crop and livestock production. The generation of a large amount of organic waste from agriculture opens wide opportunities for the development of the biogas technologies. The aim of the paper is to identify the main waste management trends in Ukraine based on data on waste generation and waste management and to calculate the strategic potential of agricultural waste as a feedstock for biofuels production. The resource potential of crop, livestock and processing waste has been considered and the necessity of its use for energy purposes has been substantiated. It has been determined that the greatest potential of agricultural waste that can be used for biogas production in Ukraine is concentrated in crop production. The livestock industry and processing enterprises also have a powerful feedstock base for biogas production. It has been determined that the agroindustrial sector of Ukraine produces significant amount of waste. As a result of the study, it has been found that the potential volume of biogas production from agricultural waste can replace 36.1% of natural gas consumption in Ukraine.

How to manage and minimize food waste in the hotel industry: an exploratory research

PurposeThe hospitality industry is responsible for significant amounts of waste, more than one-third of which is food waste. Through the comparison between an Italian and a Romanian hotel, this paper aims to provide a better understanding of food waste management trends in the hotel industry as well as to highlight hotel kitchens and hotel food services weaknesses and opportunities to minimize food waste.Design/methodology/approachIn-depth interviews, personal communication and observations were conducted to investigate food service planning, food procurement and food waste management, as well as to better comprehend current individuals’ understanding and attitudes, infrastructures, legislative culture and opportunities either from the managerial and the employees’ perspective. Data were analyzed according to a content analysis approach.FindingsThree critical hot spots emerged from the analysis: prediction and check of guests’ attendance, communication and transparency with local suppliers and among departments within the unit and purchasing frequency and perishable food provisioning. The accurate forecasting of the number of guests and their nationality is fundamental in avoiding food waste at food service, as well as implementing transparency and communication with local suppliers.Originality/valueAlthough academia and authorities have recognized the crucial importance of food waste management, food waste research in the hotel industry remains under-researched. The present exploratory research contributes to the scarce empirical studies about hotels’ food waste, giving theoretical and managerial recommendations for supporting further studies, highlighting the need for formal deals between hotels and local suppliers (food procurement), as well as the importance of food-networks that holds together companies, retailers and charities (food donation).

Integrated solid waste management in urban India: A mini review

Blooming of industrialization and urbanization are directly corelated with increased solid waste generation. Every year India faces a massive challenge as it deals with municipal solid waste equating to approximately 62 million tonnes including E-waste, plastic and medical waste. This has mounted and stands as a budding hazard to public and environmental health. Within India solid waste management predominantly adheres to sustainable development. The waste management rules are generally framed and handled through the Ministry of Environment and Forest (MoEF); however, compliance varies among states. In this article we are describing the present status, challenges and implementation followed in the waste reduction processes including segregation/collection, recycling, energy recovery (composting, bio methanation, and bioremediation), land filling of household and industrial waste; its impact on the environment. This review concludes with some simple and effective international trends in waste management, with a vision of improving in current Indian systems.

Cooking oils and fat waste collection infrastructure planning: a regional-level outline

Among the current trends in waste management and circular economy is the involvement of new fractions of waste for sorting and collection. One of them is fats and cooking oils, especially those coming from households. Now, the nascent fat waste recycling becomes promoted as regulations and waste recovery targets have been set in the European Union. The traditional manner of discarding household fat waste usually causes sewage problems. However, utilisation of this waste brings the potential for contributing to the energy supply and material recovery. This research presents a mathematical model for the optimal location of fat waste bins and containers in the given municipalities. The container network should comprise as few containers as possible, while the walking distance for the citizens towards the container is as short as possible. The objective of the proposed optimisation model is to minimise the total number of collection points (infrastructure cost). The collection points represent the citizens’ addresses in a municipality. The average walking distance towards a container is a novel feature in the model, which is pertinent to waste fractions with low production per person. Cluster analysis describes the variability between municipalities, and further, it is possible to use regression analysis to model the number of containers for any municipality or region. The proposed general decision support tool estimates the total cost and number of bins needed for any region or a country. The region from the Czech Republic, which was used as a study area, revealed the requirement for 609 containers, with only EUR 30,000 of investment cost. There are around 950 inhabitants assigned to a single collection point on average.

Acoustic panels based on recycled paper sludge and lime composites

Recent trends in waste management have initiated interest in recycled materials for sound absorption applications. The present paper studies the possibility of paper sludge to be recycled as material for sound absorption applications. Paper sludge (PS) is the water treatment waste, produced during paper production. Two different methods were studied to produce paper sludge and slaked lime composite acoustic panels for sound absorption applications at low and mid-frequencies. The sound absorption coefficient of paper sludge composite panels is measured in an impedance tube using the two-microphone method. The samples produced with different methods showed different behaviours of sound absorption. The primary method to produce showed acoustic asymmetry in the vertical direction of the samples, and it was considerably fragile as well. An improved method to produce PS composite panels was proposed in this paper. Using this method, homogenous and robust acoustic panels were obtained.

COAL INDUSTRY: ENVIRONMENTAL IMPACT AND WASTE MANAGEMENT ASSESSMENT

A study was carried out to assess the environmental and technical indicators of coal enterprises activities in coal mining and formation and waste treatment trends statistical data. It is proposed to analyze waste management trends using dimensionless coefficients (Krec, Kincin, Kland): recycling, incineration or landfill disposal. They are indicators of time dependence and represent a mathematical expression in the form: the ratio of recycled, incinerated or disposed volumes of waste to the volume of waste generated per year. The expediency of using the specific emission of pollutants' values for each pollutant and from each source of emission has been substantiated in general for production. It has been proven that such an approach allows the practical possibility of objective control over the actual emissions of pollutants and establishes a relationship between the amount of pollutant emitted and the activity or inaction associated with this ejection. It has been established that in recent years, the decline in coal mining has led to an unjustified increase in emissions of pollutants at many state-owned enterprises. It has been established that minimization of generating, reuse, recycling and recovery of waste is in no way reflected in the waste measures for the management mining industry waste, but it rather reflects a slowdown in measures to protect and preserve the environment. It has been proven that the main method used in Ukraine is the creation of dumps or storage facilities. Calculation of the operations ratio with waste (utilization, incineration, disposal) to the volume of formation of the latter showed that Krec is gradually decreasing, while Kland displays an active increase (by 1.5 times). It is concluded that the EU directives on waste management are not fully implemented (primarily, this concerns waste recycling); it is advisable to provide either the reuse of the mining waste, or the adding value - by converting waste into something else.

Analysis of incombustibles in the feedstock to incineration facilities in South Korea for optimum sorting and management.

Korea's Ministry of Environment has implemented the Framework Act on Resource Recirculation to activate waste resource recovery. However, industrial waste treatment facilities have some problems related to diversity of waste received for proper management of wastes. Waste incineration facilities are required to receive and process combustible waste and are forbidden to re-consign waste to other waste treatment facilities without any processing. In reality, a large amount of incombustibles is injected into the incinerator because it is impossible to completely separate the incombustible materials. Therefore, it is necessary to develop additional management criteria for optimal operation of the incineration facility. This study was conducted to improve institutional management of incineration facilities in Korea. Through a literature review and statistics study, incombustible waste management trends were investigated. The characteristics of waste entering incineration facilities were surveyed. Physical composition and proximate analysis of incoming waste were conducted, and properties of the incombustibles mixed in feedstocks to waste incineration facilities were examined. As a result of this study, incombustibles mainly consisting of the construction and demolition waste, such as soil, glass, and metals, should be separated from feed sent to incinerators. A mechanical screening technique that sorts particles of 30-40 mm in size can be used to separate the incombustibles. Also, management criteria could be proposed to sort and re-consign the incombustibles.
