Identification and characterization of potential compost degrading bacteria from agro-waste

Agricultural industry plays a significant role in the global economic growth. It is estimated more than 15% of total waste in Asia are contributed by agro waste. Bacteria is known as one of the useful organisms actively found to surround the waste industry. They are considered as chemical decomposers and act as driving agent of composting that changes the chemistry of organic waste to simple compounds. Thus, this study was conducted to isolate and identify potential compostdegrading bacteria from agriculture waste at several sampling areas in Besut district, Terengganu, Malaysia. A total of 49 bacteria strains were isolated using Tryptic Soya Agar (TSA) from seven groups of raw agro wastes (paddy husk, paddy straw, paddy soil, rock melon waste, rock melon soil, corn waste, and corn soil). Primary screening for potential enzyme production was carried out using selective media containing different substrates (sucrose, xylan, starch, skim milk, and pectin). Only 13 bacterial strains were found positive for protease, nine bacteria strains positive for xylanase, and three bacteria strains were found positive for amylase. Identification of bacteria strains were performed using phenotypic, biochemical tests, and genotypic approaches by 16S rRNA gene sequence. Based on NCBI BLAST analysis, we have identified several bacteria strains: Bacillus cereus (strain B), Alcaligenes faecalis (strain C), Micrococcus sp. (strain D), Pseudomonas stutzeri (strain E), Enterobacter cloacae (strain G), and Serratia marcescens (strain J). Strain F and strain H were identified under distinct family of Enterobacteriaceae, while strain I was identified from Pseudomonadeles order which might represent a new type of proteobacteria strain. These potential waste degrading bacteria could be further analyzed and studies for their true potential in many areas including agriculture and industrial waste management as an approach to reduce waste accumulation in eco-friendly way.

BIOCHEMICAL CHARACTERIZATION OF VEGETABLES WASTES AND DEVELOPMENT OF FUNCTIONAL BREAD

The present study aimed at evaluating nutritional potential and antioxidant activity of the extracts derived from vegetable wastes such as carrot pomace, onion upper bulbs, and peels from garlic, tomato & potato. Proximate composition, minerals profiling and antioxidants activity as 2,2-diphenyl-1-picrylhydrazyl (DPPH) and trolox equivalent antioxidant capacity (TEAC) were estimated, and phenolics characterization was performed using high performance liquid chromatography (HPLC). Our results suggest that vegetable wastes such as peel and pomace, may be exploited as carriers of proteins, fiber, calcium, potassium, iron and zinc. Phenolics screening demonstrated presence of total hydroxybenzoic, hydroxylcinammic acids and catechin albeit anthocyanins and total flavonols were inadequately present in tomato pomace. Maximum total phenolics contents and DPPH activity were observed in HCl/MeOH extracts of tomato and garlic peels, respectively. Product development data suggest incorporating onion peel’s extracts in wheat flour to not elicit a significant change in bread composition. Likewise, supplementation of onion peel powder (OPP) and extracts @ 6% and 1.5%, respectively improved color and textural properties of supplemented bread. Contextualizing the challenges of food insecurity and food industry waste management, our results confirmed that vegetable wastes, with improved nutritional profile and increased antioxidant potential, may be used for the preparation of value-added food products.

Organic Waste Conversion Via Continuous Anaerobic Co-Digestion of Oil Palm Empty Fruit Bunches and Cow Manure: Evaluation of Feeding Regime on Methane Production

Abstract Anaerobic co-digestion of oil palm empty fruit bunches with cow manure was studied. The research focus was on the evaluation of feeding different solid concentrations of the substrate in the on-going process of anaerobic digestion. The solid concentrations ranged from 0.5 to 12% TS. Results of the study showed that the maximum methane production could be reached with the reactor digesting substrates with 4 to 8% TS, in which the methane produced was from 1300 to 1400 mL per day. A significant drop of pH from 7.02 to 5.97 occurred when the reactor was digesting substrates with 10 and 12% TS. Acidic condition caused by organic matter overloads lowered the efficiency of organic conversion represented in the low removal of COD, which was only 22.4%. This finding is highly significant for the waste management industries in terms of dealing with the digester upset due to the digestion of large amount of organic wastes.

State and regional policy on industrial waste management: the EU experience for Ukraine

Purpose. To identify the main trends caused by the divergence of the policy of Ukraine and the EU in the formation and accumulation of waste and threats to the environment. Methodology. Using the methods of content analysis, quantitative and qualitative comparison, EU policy on waste management is analyzed and logical generalization is used to establish the features of waste management financing for industries and regions. Findings. Regional irregularities of industrial waste accumulation, including hazardous waste, trends of their change are revealed. The reasons for regional peculiarities of waste management in the EU and Ukraine are established. It is established that the distribution of capital investments both in environmental protection in general and in waste management in particular does not always coincide with the leading regions of accumulation. It is established that limitation of financial instruments for waste management only by budgetary resources leads to a reduction in capital investment. A comparison of trends in environmental spending and waste management indicated a significant difference. Analysis of environmental investment by polluting industries, which are unevenly represented in different regions, revealed a significant difference between them. Originality. Regions that are the main polluters have been identified. The discrepancy between trends of capital investments in environmental protection and waste management was revealed. It is established that the list of leading regions in terms of capital investments in environmental protection does not correlate with the list of leading regions of waste accumulation. It is pointed out that uneven investment creates risks of increasing the rate of waste accumulation, in particular hazardous waste. Forecasting of indicators of waste management of the following periods is carried out. Practical value. There are risks of increasing the rate of waste accumulation, especially hazardous waste, both in Ukraine in general and in some regions, inequalities in some areas in the amount of capital investment into environmental protection, which will form an effective waste management policy. Identifying common features and differences in waste management in the EU and Ukraine will allow implementing effective environmental protection tools, reducing risks in industrial waste management.

Waste source owners in the industrial solid waste management in Vietnam

Management of industrial solid waste is predicted becoming more complex as Vietnam develops rapidly, strives to become an industrialised country towards modernisation. In order to manage efectivelly industrial solid waste, there must be the participation of many actors in the waste management cycle, among them, it is necessary to mention the owner of industrial solid waste. Responsibilities of the owners of the industrialised solid waste that emitted to the environment are an issue that needs to be clarified in the waste management. Therefore, this paper concentrates on analysing the current laws in Vietnam defining the responsibilities the waste source owners and the mechanism to implement these responsibilities in the management of industrial solid waste. The writing figures out some limitations and inadequacies in defining responsibilities of the owners of the industrial solid waste sources. Then, it proposes a number of solutions that enhances responsibilities of the waste source owners in the industrial solid waste management. They are: 1/ Need more specific regulations on the responsibilities of the owners of the waste sources in classification of waste; 2/ Improve regulations on the market of waste goods; 3/ Supplementing regulations on specialised personnel at facilities generating industrial solid waste; 4/ Strengthen inspection, examination and supervision on the waste source owers; 5/ Improve the law on the system of economic intrusments to regulate acts of the owners of waste sources; 6/ Mobilise community responsibilities participating and promote socialisation in industrial solid waste management.

A Systematic Review on the Performance Characteristics of Sustainable, Unfired Admixed Soil Blocks for Agricultural and Industrial Waste Management

Unfired admixed soil blocks are composed of standard soil and a stabilizer or reinforcement material in the form of binder and fiber. This literature review systematically examines the performance characteristics of unfired admixed soil blocks made by using binders such as cement, lime, and other agricultural and industrial wastes available in the form of fibers and ash. A systematic search was carried out on Web of Science and SCOPUS using different keywords, and 313 records were found. After the screening and eligibility process as per PRISMA guidelines, 36 papers were eligible and hence selected to be reviewed and analyzed. This paper examines the performance characteristics of the blocks in terms of physical properties, mechanical properties, durability, microstructural evaluation, statistical analysis, cost analysis, energy consumption, and carbon dioxide emission. It was found that of the total 9 parameters considered for discussion, most of the studies using different admixtures (binder and fibers) in soil blocks were focused on compressive strength testing of blocks, water absorption, and durability by wetting drying cycles. However, other parameters like bulk density, maximum dry density and optimum water content, thermal conductivity, tensile strength, and flexural strength examined in recent studies are also reported in this paper. This systematic review proposes some research problems to be worked on various additional parameters like linear shrinkage, pull out test, erosion test, sorptivity test, porosity, efflorescence, water permeability, freeze/thaw test, and analysis of energy consumption and carbon dioxide emissions during the manufacturing of unfired admixed soil blocks using various binders and fibers for further study which the current literature lacks.

Financing of environmental programs for industrial waste management in times of crisis

Purpose. To conduct an analysis of funding from state and regional budgets for environmental needs in general and itemized as waste management, to identify correlations of data and to build on their basis a mathematical apparatus for forecasting the financing of environmental needs in the event of a budget crisis. Methodology. The results of the study were obtained using general and special methods of cognition. Methods of comparative analysis, content analysis and logical generalization were used to analyze the financing of environmental needs in general as well as waste management, in particular. Methods of quantitative and qualitative comparison were used to detect data correlation and isolation from random effects on the resulting function of non-random components. Methods of scientific abstraction and mathematical formalization were used to form a mathematical apparatus for forecasting the financing of environmental needs in the event of a budget crisis. Findings. It is proposed to introduce a strategic systems approach to address pressing issues of environmental protection and industrial waste management in the face of a shortage of financial resources both at the state level and at the regional level. The mathematical apparatus has been formed for this purpose. The increasing relevance of the forecast was achieved by introducing an original methodology. Trends and features of budget financing of ecological programs at the state and regional levels are revealed. With a chronic lack of financial resources, there is a tendency of a steady increase in current costs of waste management. Peculiarities of financing ecological needs from regional budgets are studied. It is stated that regional budgets are affected not only by the risks inherent in national funding, but also by their own sets of risks. Originality. The presence of correlated components in white noise of ARMA-models increased the relevance of forecasts of financing environmental programs in the crisis. The practical reliability of the correlation between some components of white noise and the integrated indicator of the level of economic security is established. It was found that the financing of environmental programs from regional budgets is characterized by more uneven changes than in the case of state funding. Practical value. Forecasts for the volume of industrial waste for disposal in specially designated places and the volume of capital investment and current costs of waste management have been developed. The possibilities of the mathematical model for the formation of forecasts of future periods are tested. Forecasts for the following years and approximations of previous periods are presented in a convenient analytical form to be used by specialists. Forecasting budget revenues for environmental needs allows planning a phased solution to environmental problems and attracting the necessary external financial resources, increases the ability of public control of financial flows and access to the planned indicators of each of the environmental investment objects. In a broader sense, it provides a tool for shaping the sphere of environmental protection as a single system.

Current key options for management of industrial alkaline waste of alumina production (red mud)

Due to the ever-increasing demand of the world economy for aluminum, its alloys and compounds, the production of this metal is increasing annually throughout the world. This leads to an increase in the industrial production of alumina, which is obtained from bauxite ore in the Bayer process. After recovering the bulk of the aluminum from the bauxite ore, there remains a residue which is highly alkaline toxic waste, which is also called bauxite residues (tailings) or red mud (RM). About 140-150 million tons of RM are produced annually and almost 4 billion tons have already been accumulated. At the moment, the problem of RM recycling and the development of effective and cost-effective approaches to their reprocessing is extremely urgent. Reducing RM affects economic, environmental, social areas and is a prerequisite for the sustainable development of nature and society. Despite active scientific research and efforts to develop and optimize various methods for RM recycling and reprocessing, the problem of an annual increase in their volumes around the world remains unresolved. Recently, promising and efficient processes have been proposed that allows for the complex reprocessing of RM with the extraction of a number of valuable liquid products that may be in demand in various fields of industry. This allows to focus on large-scale disposal of RM and can be a solution to the problem of handling these industrial wastes. The article considers the main current trends in the field of management of various types of RM with a focus on complex reprocessing and zero waste concepts.

COVID-19 impact on air quality and associated elements: knowledge data of the Emirate of Ajman − UAE

Air pollution is one of the core issues at the local and global levels and maybe “one of the most important contributors” to deaths. According to the United Nations, air pollution is one of the extreme environmental threats to health globally. Air pollution problems increased worldwide due to the massive emission volumes generated every day from the increased lifestyle associated technology. The air pollutants are not only dangerous to the health and wellbeing of plants, animals, and people, but they are also harmful to the environment as a significant contributor to recent climate change. The reduction in the volume of pollutants produced is a crucial and challenging step in managing our adverse effects on the environment and climate. The primary outdoor pollution sources include vehicles, Industry, power generation, building heating/cooling systems, and agriculture/waste incineration. The regulation, policies, clean production, investments supporting cleaner transport, energy-efficient housing, power generation, Industry, and better municipal waste management can effectively reduce critical sources of ambient air pollution. When many countries of the world are fighting the Coronavirus, as a challenge to limit its spread, because of its negative repercussions on the economy, health, and political stability as well, several reports have emerged confirming that the spread of the virus has positive effects on the climate change crisis through its impact on the demand for energy and greenhouse gas emissions in endemic countries. Ajman is an emirate that has experienced considerable change in the level of air-associated pollution. Therefore, this article aims to assess air quality impacts in the Ajman Emirates during the lockdown when social distancing was implemented, and human activities were significantly eliminated. Moreover, it seeks to identify the percentages of the improved outdoor pollutants concentrations and the general air quality index. This paper shows evidence from live measurements that the Emirate has recorded over four months since the lockdown was imposed at this Emirate and compared with similar months of the previous year. Moreover, it indicates that having climate improvement exists for specific periods could well support the fight against the COVID-19. The article clearly shows results with a significant reduction of more than 40% of each air-associated pollution element during the pandemic compared with similar periods in 2018 and 2019.

The article describes the organizational regional structure of industrial waste management in modern Ukraine, which will improve the efficiency of industrial waste management systems and industrial energy facilities in Ukraine. The structure of industrial waste management at different system levels, from the national to the level of an industrial enterprise, is described. The data on the recommendations of the World Health Organization on the emissions of toxicants into the air and the data of the State Statistics Service of Ukraine on the content of the main pollutant gases in air emissions from stationary sources of Ukraine from 1990 to 2018 are presented. The scheme of the negative impact on the environment of emissions of pollutants from stationary sources – production facilities of coal mining and coal processing is characterized. Comparative data on the indicators of the volumes of toxic waste generation at the enterprises of European countries and the heavy industry of Ukraine are given. It is shown that the main sources of the impact of coal processing enterprises and coal processing industries on all spheres of the environment are organized and unorganized dust and gas emissions, discharges of process wastewater and effluents from the surface and from the volumes of dumps and sludge collectors of coal processing plants. As a result of comprehensive research by the authors, a number of coal dumps of concentrating factories in Eastern Ukraine have been studied, migration routes and concentration of rare and heavy metal compounds in the soil near coal dumps have been investigated. Rather stringent standards for the content of hazardous substances in industrial waste require special methods for neutralizing coal sludge before final disposal and / or disposal.of the raw materials used to obtain humic acids. The corresponding equations are given. Keywords: coal sludge, coal preparation plants, coal dumps, sludge collectors, surface runoff, environmental pollution, emissions into the atmosphere, gaseous, liquid and solid toxicants.

Dye removal from wastewaters using grape seed residues

Dye removal from industrial wastewaters is a constant concern in industry, like textile or paper, since the consumers demands are in continuous increase and new dye combinations are developed and used. Therefore, efficient, and environmentally friendly dye adsorbents are a continuous necessity. This research aims to characterize the absorbents capacities of grapeseed material (rest material after grapeseed oil extraction). Apart from adsorbent characterization, the influence of contact time, adsorbent quantity and the influence of the solution pH are investigated. Following the principles of sustainability and circular economy, the transformation of by-products during the process of obtaining grapeseed oil into a usable absorbent material could resolve two major issues in two of the largest industries: wine industry waste management and removal of dyes from the textile industry wastewater.

Динаміка утворення відходів будівництва i знесення у Вінницькій області

Solid industrial waste can be widely used in construction to obtain such valuable materials: as a filler and binder for the production of concrete, dry building mixtures and other building materials, for the production of building materials with protective properties against electromagnetic radiation and static electricity, for the manufacture anode earthing switches, etc. Therefore, the determination of the regression dependence describing the dynamics of the generation of construction and demolition waste in Vinnytsia region to solve the problem of solid industrial waste management is an urgent scientific and technical problem. The aim of the study is to determine, using regression analysis, the dependence that describes the dynamics of construction and demolition waste generation in Vinnytsia region to solve the problem of solid industrial waste management. The study used the method of regression analysis of the results of one-factor experiments and other paired dependencies with the choice of the best type of function from the 16 most common options according to the criterion of the maximum correlation coefficient. The regression was carried out on the basis of linearizing transformations, allowing reducing the nonlinear dependence to linear. The determination of the coefficients of the regression equation was carried out by the least squares method using the developed computer program "RegAnaliz", protected by a certificate of registration of copyright for the work. Adequate regression dependence was obtained that describes the dynamics of construction and demolition waste generation in Vinnytsia region. A graphical relationship has been built that describes the dynamics of construction and demolition waste generation in Vinnytsia region and allows to visually illustrate this dynamics, to show sufficient convergence of theoretical and actual results. It was found that in Vinnytsia region during the period of 2014—2018 the formation of a mass of waste from construction and demolition decreased hyperbolically. Such a mass of construction and demolition waste generation in Vinnytsia region in 2025 is predicted — 331 tons, and in 2030 — 223 tons.

Institutional approach to assessing the transition to a circular economy: the case of the Kaliningrad region

The article discusses possible reasons for the failure of Russia’s waste management industry reform and highlights the ownership blurring as a factor that may hinder the transition to a circular economy, which has been proposed as one of the outcomes of the reform. This study aims to address possible obstacles to transitioning to a circular economy in the Kaliningrad region. Methodologically, the study uses instruments of new institutional economics: by comparing discrete institutional alternatives for municipal solid waste (MSW) management, the authors propose incentive schemes that will likely stimulate the transition to a circular economy in the region. It is shown that, in Russia, the identification of the holder of the property right to waste is complicated. This can be a hindrance to effective MSW management. Moreover, objects handled by MSW management services may fall into different types, but at the same time, it is possible to transfer objects from one type to another. One of the ways to improve the exclusion of services of MSW utilization is the introduction of incentive tariffs. Low-rise housing in the Kaliningrad region makes it an ideal region for the introduction of such a scheme. When calculating the unsorted waste transport fee, a multiplier can be used to reduce the payment for waste-separating households. This can serve as an additional incentive for overcoming collective action problem in MSW collecting and sorting. To prevent social resistance to such a policy, incentive schemes should be implemented on a voluntary basis.

An Introduction Assessment of Household Waste Management Strategy Problems and its Impact in Capital City of Dili: A Preliminary Literature Review

The waste management strategy is expected to minimize the negative impact on the environment. In the capital city of Dili, the waste management strategy can be categorized as very concerned. Based on the data from the Ministry of State Administration shows that in 2020, people in the capital of Dili produce waste 250 tons per day. The reality of solid waste in the capital city of Dili shows a severe problem in the waste management process and strategy. This study aims to examine problems in waste management strategies and their impact in the capital city of Dili. Through a literature review approach, a scientific study will be carried out on several scientific articles related to the waste management system and the reality of solid waste in capital city of Dili. The results show that people in the capital of Dili, still use the classical system in managing solid waste. Weak government system and local regulations regarding to solid waste management, and the lack of the waste management industry based on R3 (reduce, reuse, recycle) are the main factors for the community still using the classical system. This reality harms the environment and people in the capital of Dili.

ІНВЕСТИЦІЙНЕ ЗАБЕЗПЕЧЕННЯ СФЕРИ ПОВОДЖЕННЯ З ВІДХОДАМИ ЯК СКЛАДНИК ЕКОНОМІЧНОГО МЕХАНІЗМУ ПРИРОДОКОРИСТУВАННЯ

The article considers the systemic characteristics of investment support for waste management as a component of the economic mechanism of nature management. It is revealed that the economic mechanism of nature management operates with a set of methods, tools and methods of influencing the processes of Environmental Protection, which are provided through the functioning of environmental infrastructure facilities in the public and corporate sectors, as well as in the household sector. It is established that an important component of the environmental infrastructure is the material and technical base of waste management, which provides placement, storage, sorting, disposal, and incineration of industrial and household waste. It is proved that modernization, reconstruction and technical re-equipment of the waste management industry require a significant amount of investment injections. It depends on the availability of an institutional environment for stimulating the investment process. Studies have shown that in 1996-2020, in Ukraine as a whole, there is an upward trend in the dynamics of capital investment in waste management, but the growth potential of investment injections into this component of environmental infrastructure is not fully used. It is established that the increase in investment injections in the modernization and reconstruction of the waste management industry depends on the inclusion in the economic mechanism of nature management of a complex of fiscal, credit and budget incentives for environmental business entities specializing in waste placement, sorting and disposal. It is proved that in the context of deepening decentralization of power, in particular, increasing the resource capabilities of United territorial communities, the institutional framework for increasing the amount of investment in the development of the waste management industry is significantly expanding, provided that local self-government bodies and business entities enter into statutory and non-statutory associations or conclude agreements between municipal and private partners. It is proved that the highest level of effectiveness of stimulating investment in the waste management sector is observed in the conditions of cluster formations, where coordination of the activities of municipal and corporate partners, as well as the household sector, is ensured to increase resource and financial flows in the modernization and reconstruction of the household waste disposal industry.
