Implementation of Circular Economy Principles in Industrial Solid Waste Management: Case Studies from a Developing Economy (Nigeria)

The existing solid waste management principles are increasingly being replaced with discussions on circular economy (CE) principles in contemporary deliberations on solid waste handling. This shift is supported by the global adoption of the concept of sustainable development. The CE offers better prospects to solid waste management and has been implemented successfully in its full theory, practice, and policies in some developed locations of the world. The socio-economic disadvantages, insufficient expert knowledge and a lack of information have hindered its appropriateness and implementation in low and middle-income countries. Hence, the current research study examines the challenges and opportunities of implementing the circularity principle at the industrial sector level of a typical developing economy—Nigeria. Four different industries were selected for this case study—telecommunications, water packaging, pulp and paper and the food industry. These industries represent the major waste streams in an urban solid waste mix (waste electrical and electronic equipment (WEEE), plastic, paper and organic). This study discovered several barriers and existing pre-conditions in place that could either foster or militate against the smooth and successful application of a CE model as a simple modification of the generic model. This study also discussed future directions on the implementation of the model.

Optimization of post-treatment variables to produce hierarchical porous zeolites from coal gangue to enhance adsorption performance

Our research data indicates that a cost-effective hydrothermal synthesis with optimized post-treatment variables can provide a feasible paradigm to convert the coal gangues into valuable zeolites. It is found the integrity of skeleton structure of these cubic zeolites is well maintained upon series of post-treatments. The effects of these treatment parameters indicate concentration of NaOH solution (3.0 mol/L), alkaline treatment time periods (2 h) and temperature (90 °C), and ultrasonication time duration (40 min) collectively affect on the crystal structure, morphology, and adsorption performance of these zeolites. The specific surface area of treated zeolite is measured to be 162.29 m2/g and significantly increases compared with the untreated one (64.28 m2/g). The mechanistic study of zeolites post-treatment suggests that the erosion of parts of Al-OH and Si-OH bonds and the expansion of pore size will lead to a formation of hierarchical mesopores. As a consequence, the removal efficiencies of these modified zeolites have been greatly improved to 83.5% and 95.1% for Cu2+ ions and Rhodamine B (Rh-B), respectively. It is critical to point out that the subsequent alkaline and ultrasonic post-treatments greatly improve the adsorption performance of multiple mesoporous zeolites prepared from coal gangue. The post synthetic treatment can provide a platform of environmental cleanup applications such as industrial water remediation and solid waste handling by conversion of mining wastes into a value-added product.

The policy-making trend analysis of municipal solid waste in China 1980-2015.

Over the past 35 years, the Chinese government has established various policies to tackle problems related to the municipal handling of solid waste. It is necessary to study policy-making trends in the area of municipal solid waste for further sustainable development in China. This article fills this gap by designing a new analytical framework made up of policymaker indicators, policy practitioner indicators, policy beneficiaries' indicators, policy tool indicators, and policy support indicators in order to analyse the policy-making trend based on China's major municipal solid waste policies from 1 January 1980 to 1 March 2015. Results have shown that policy-making related to municipal solid waste has changed significantly in the past 35 years and that more municipal solid waste policies were issued by one or a few ministerial departments than by the State Council and National People's Congress. Moreover, the study has shown that the government and companies have dedicated more attention to taking action about municipal solid waste than individuals. With regard to the policy tools, policy-making has stressed the use of market-type tools, regulation-type tools, and public participation-type tools together to tackle the municipal solid waste problem since 2000. Finance and information support were used more as policy support by municipal solid waste policies than technology. This article provides some novel insights on the policy-making trend of municipal solid waste in China.

Current Scenario of the Tehran Municipal Solid Waste Handling Rules towards Green Technology.

This study aims to study the waste management process and recycling of municipal waste in Tehran. Currently, Kahrizak is the defined landfill area which collects the waste generated from 22 districts of Tehran. The organic wastes undergo to the windrow composting method in order to manage the partial of the waste generated in the city. Samples from the compost pile generated in Kahrizak were examined to evaluate its fertilizer value to be used further by the farmers. The results show that the obtained compost does not reach the acceptable quality to be used further in agriculture, due to lack of homogeneity, aeration and presence of heavy metals. Overall, it has been concluded that, due to the improper waste segregation and management prior to sending to landfill and presence of non-organic materials such as hazardous metals and medical wastes, causes difficulties in proper waste management, implementation and producing high quality compost. Based on this study the existence of stakeholders, society, economy and proper handling rules can effectively improve the waste management system in the country and leads to the sustainable green environment.

Law Relating to E-Waste Management in India: A Critical Study

India is one of the heftiest waste importing nations across the globe. All types of wastes are trade-in into the India, in the form of cheap raw resources together with perilous and noxious wastes. Data released by the Customs Department reveal imports of even prohibited wastes similar to clinical waste, incineration ash, municipal waste and e-waste, all of which exceed 5 million tonnes annually. In 2009, India generated 5.9 million tonnes of perilous waste domestically and trade-in 6.4 million tonnes.The issue of electrical and electronic tool clearance, trade-in and remanufacturing has become the subject of stern discussion and debate among the Government organizations, environmentalist groups and the private segment manufacturers of computers and end-user electronic equipment’s. The Department of Parliamentary Standing Committee on Science & Technology, environment & Forests in its 192nd Report on the Functioning of the Central Pollution Control Board (CPCB), has concluded that e-waste is going to be a big problem in the future due to modern life style and increase in the living standards of people and augmentation of financial expansion. This paper analyse the available laws relating to e waste management like the Municipal Solid Waste (Management and Handling) Rules, 2000, the Hazardous Waste (Management, Handling & Transboundary) Rules, 2003, the Environment (Protection) Act, 1986, The Hazardous Wastes (Management, Handling and Transboundary Movement) Rules, 2008, and The E-waste (Management and Handling) Rules, 2011.

Review on the Characteristic and Feasibility of Leachate for Biogas Production by Anaerobic Digestion

The sound handling of municipal solid waste (MSW) is of high priority to minimise environmental degradation and pollution. MSW can be treated via various technologies including landfilling, incineration, composting, anaerobic digestion (AD) and more. Landfill without landfill gas capturing serves as an enclosed bioreactor to store and stabilise waste. Other technologies such as incineration, composting and AD allow substantial volume reduction and generate value-added products. The treatment for MSW is commonly focusing on the solid part. Organic waste contains high moisture content of 70 - 90 %. The pressing of the water content before entering treatment unit, the release of water during and after the treatment, can generate high strength wastewater, known as leachate. Leachate is rich in organic matter, organic pollutants, pathogens, heavy metals and more, which can lead to severe secondary environmental pollution if not properly treated. Leachate from different treatment units showed certain unique characteristics, such as high Na, high Ca , different species and availability of heavy metals. This review summarised some of the important characteristics of different leachates and the suitability of AD as a mean of treatment. The efficiency of AD to treat leachate was presented in terms of the removal efficiency of chemical oxygen demand (COD) and biogas production. The COD removal efficiency was between 60 - 98 %, following the treatment of different leachates under different reactors and operational parameters. Among the different stream of leachates, the leachate from landfill is most commonly studied as a co-digestion substrate for AD, as compared to leachate from the composting facility.

Minimization of municipal solid waste transportation route in West Jakarta using Tabu Search method

Indonesia still adopts the concept of collect-haul-dispose for municipal solid waste handling and it leads to the queue of the waste trucks at final disposal site (TPA). The study aims to minimize the total distance of waste transportation system by applying a Transshipment model. In this case, analogous of transshipment point is a compaction facility (SPA). Small capacity of trucks collects the waste from waste temporary collection points (TPS) to the compaction facility which located near the waste generator. After compacted, the waste is transported using big capacity of trucks to the final disposal site which is located far away from city. Problem related with the waste transportation can be solved using Vehicle Routing Problem (VRP). In this study, the shortest distance of route from truck pool to TPS, TPS to SPA, and SPA to TPA was determined by using meta-heuristic methods, namely Tabu Search 2 Phases. TPS studied is the container type with total 43 units throughout the West Jakarta City with 38 units of Armroll truck with capacity of 10 m3 each. The result determines the assignment of each truck from the pool to the selected TPS, SPA and TPA with the total minimum distance of 2,675.3 KM. The minimum distance causing the total cost for waste transportation to be spent by the government also becomes minimal.
