The management of MSW is a major concern in several cities of developing countries due to its public health and environmental sustainability implications. This paper thus presents an overview of the current solid waste management practices and problems in some selected states in Nigeria. In addition to the comprehensive review of MSW generation, its characterization, collection, and treatment options in the considered states, an attempt was made to evaluate the major waste–to–energy indicators such as calorific values and energy (electricity) recovery potential. The legislations in place at the federal level to maintain healthy environment is also lucidly presented. An estimated electricity recovery potential in the range of 48.31 to 933.69 MW with a total of about 2600MW from six states was established. Evidences from literature suggested that the existing solid waste management system is inefficient due to uncoordinated and properly planned waste management system. This paper concludes that the thermochemical conversion of waste-to-energy into electricity is a feasible option in Nigeria, although this might require the input of additional quantity of fuel to initiate combustion since the lower heating values of the considered MSW fall below the optimum stipulated by World bank.

Solid Waste Management System

According to decision no. 491/QD-TTg signed in 2018 by the Vietnamese Prime Minister approving adjustments to the national strategy for the general management of solid waste until 2025 with a vision toward 2050, Vietnam has committed itself to move toward collecting, transporting, and treating 100% of non-household waste by 2025 and 85% of waste discharged by households by 2025. This paper aims to determine which is the best sustainable solid waste management system out of those that have been formulated by World Bank experts for Hanoi until 2030 for implementing the national strategy. The paper compares four distinct solid waste management enhancement alternatives, namely, “Improving the current system for waste collection and transportation”; “Reducing, reusing, and recycling waste at source”; “Mechanical–biological treatment (MBT) plants for classifying, composting, and refuse-derived fuel (RDF) for the cement industry”; and “MBT plants for classifying, composting, and RDF for waste-to-energy/incineration plants”. The comparison was made using an analytic hierarchy process. As a result, the research indicated that “MBT plants for classifying, composting, and RDF for waste-to-energy/incineration plants” has the highest ranking in terms of a sustainable solution for the municipal solid waste management system. Therefore, it should be applied for managing the current situation in Hanoi. At the same time, the sustainable development of the system must seek to decrease the waste-to-energy ratio continuously and significantly through the planned reuse of materials that can be recycled to industry. According to the literature, in major cities in Asia and Africa, development programs are moving toward waste-to-energy solutions. The EU’s circular innovation programs and action plan may be in the opposite direction to this trend.

ecomaine manages solid waste for its member communities through an integrated strategy that includes a single sort recycling center, a waste-to-energy (WTE) power plant and a 250 acre landfill for residual ash. The public organization has over 40 member communities in Maine which equates to over 24% of the State’s population. Established as a non-profit in the 1970’s with a mission to address trash disposal for future generations, a comprehensive waste system has emerged. The method of balefilling municipal solid waste (MSW) was replaced by a state-of-the-art WTE facility in 1988 and the multiple-sort recycling system was upgraded to a single-sort advanced system in 2007. Roughly 170,000 tons of MSW are processed through the WTE facility each year. This results in an average of 83,000–105,000 megawatt-hours of electricity generated annually. Since 2005, recycling tonnage has increased 71% from 21,000 to 36,000 tons. The State of Maine established a “Solid Waste Management Hierarchy” in 2007 cascading in disposal preference from Reduce, Reuse, Recycle, Compost, Waste-to-Energy to Landfilling MSW. ecomaine is researching the feasibility of implementing an organics recovery system that would include food waste to further advance the Solid Waste Hierarchy and State’s recycling goal of 50%. ecomaine continues to manage its resources through innovation that highlight the resiliency of an integrated waste management system. For example, ecomaine has adapted to periods of waste shortages through strategies of caching MSW during times of higher waste generation and storing that waste until it is needed. ecomaine selects cover material for temporary use that is combustible so that it can efficiently be processed through the WTE facility. When fuel is scarce, the cached material is returned to the WTE as a fuel input. Another example, of matching a waste to a beneficial reuse is ecomaine’s ash metals mining project for the recovery of both ferrous metals and valuable non-ferrous material from screened ash. ecomaine strives to sustainably treat residual waste streams after enhanced resource recovery, re-use and recycling efforts and embrace an integrated waste management system. While challenges face many waste disposal operations such as changing regulations, ecomaine communities believe an integrated system with a good design and forward-looking plant management allow for a robust and effective service, as the ecomaine example shows.

St. Petersburg, as the second most important Russian city in Russia is facing with waste related problems which requires taking immediate actions. The excessive diurnal volume of municipal waste generation and insufficient waste management system ring the bells to warn the decision makers. Focusing on problems, insufficiencies and opportunities of the waste management system, the paper goes through the evaluation of details of the dominant situation in St. Petersburg and two models are introduced to improve the system. At the end, an estimation of biofuel, heat and electricity generation will be provided for four incineration facility installments with design capacity of each 315,000 tons of waste per day. It will be shown that the contributing share of bioconversion processes is significant and an acceptable portion of 8% of annual electricity consumption can be supplied via those processes as well as production of 477 million liters of ethanol.

Intervention Scenario

The increase in waste generation is a major problem especially for urban areas such as Jakarta with insufficient landfill capacity and an inefficient and environmentally sound waste management system. To produce an optimal, integrated and sustainable landfill management strategy, an analysis of the TPST Bantargebang waste management system is then formulated towards optimization of sustainable landfill management in environmental, financial, and social aspects through a system dynamics intervention scenario model of the TPST Bantargebang waste management system. Based on the descriptive analysis carried out on the latest waste management, 3 main issues are known, namely, landfill capacity almost fully occupied, methane gas emissions increment, and the possibility waste pickers integration to increase scavenging productivity. Simulations were carried out with a system dynamics model for the 2018-2023 period with BAU conditions and an intervention scenario with a reduction in landfill waste and a reduction in waste flow. The results of the scenario are: landfill can still be utilized until 2023; methane gas emissions decreased by an average of 23,50%; the increase in the Scavenger Production Ratio to the Landfill Waste Rate reached 134,58%. As a consequence of the intervention and the addition of waste treatment activities in the TPST Bantargebang, the operational cost per ton has increased up to 309,62%. This study concludes that the scenario of incoming waste reduction and existing landfill waste reduction planned by Material Recovery Facility (MRF) construction with scavenger involvement, compost processing efficiency improvement, construction of Waste to Energy (WtE) facilities in the form of incinerator, landfill mining, and reprofiling simultaneously.

An efficient and effective waste management system is one of the key issues for urban areas. Such a waste management system should be effective and economically viable with minimal environmental impact. The Life Cycle Assessment (LCA) methodology is an effective tool for identifying and assessing environmental impacts, it also enables comparing alternative waste management options. The aim of this study is to identify and assess the environmental impacts caused by the waste management system of mixed municipal waste for the city of Krakow for the year 2017. Three scenarios are evaluated for mixed waste: 1) incineration in a new waste-to-energy plant, 2) mechanical-biological treatment (MBT), ballast and stabilized waste is landfilled, refuse derived fuel (RDF) is produced but not incinerated, 3) treatment in the MBT plant, with incineration of RDF in the waste-to-energy plant. The results of modelling show that all scenarios exert a negative impact on the environment in some impact categories, while in other categories - a positive impact. Taking into account the values in all impact categories, the scenario with the lowest overall environmental impact is MBT with incineration.
