“…Garibay-Rodriguez et al 12 formulated an MILP model to locate the optimal design of landfill gas to energy system of a medium-sized city in Mexico. Mohammadi et al 13 focused on optimizing the entire supply chain of MSW. An MILP model was developed to optimize the total profit of MSW supply chain system.…”

A large quantity of municipal solid waste (MSW) is generated worldwide, and its effective management is a major problem in urban areas or particularly the areas where waste is dumped. Numerous technological alternatives are available for waste treatment, each with different costs and environmental footprints. For sustainable waste management, both economic and environmental aspects should be considered. Therefore, this study addresses the systematic design of processing routes for the sustainable management and utilization of MSW under economic and environmental criteria. To address this, a generic superstructure-based multiobjective optimization framework is developed. MSW superstructure composes of the potential processing routes for the waste management where MSW can be utilized for energy generation and other valuable waste-based products. On the basis of superstructure, we develop a multiobjective mixed-integer nonlinear programming (MINLP) model that simultaneously maximizes the net profit and minimizes the greenhouse gas (GHG) emissions. The developed optimization model is coded and solved in GAMS to determine the optimal most promising routes for the sustainable processing of MSW. A case of the Emirate of Abu Dhabi is employed to test the applicability of the developed framework. The optimization results emphasize that pathway 2 shows a decent trade-off between economic and environmental objectives, whereas the two most environmentally sustainable processing pathways have the potential to reduce GHG emissions by 58% and 80%, compared with business as usual (BAU) scenario, and also possess potential economic benefits. The insights gained from this analysis guide the municipality planners to devise a promising and sustainable waste management strategy.

“…Our overall consumption is continuously growing, as well as the amounts of produced waste, but the one thing that is constant is the Earth's finite resources. To find a long term solution for these challenges, we have to consider our waste management systems as a source for valued resources or resource banks [1], e.g. reuse and recycle wastes, recover energy [1] or even upgrade waste into valuable products [1].…”

“…The concept of the circular economy is assumed to hold the solution or at least a remedy for such complex global challenges, including decoupling of resource use and economic growth, resource scarcity, climate change, increased waste generation etc. [1]. Circular economy aims to overcome the linear production approach that is based on the take-make-consume and dispose trend and to transform the economy to a circular operating pattern that is improving resource and energy efficiency, and involving resource recovery and reuse [1].…”

Waste management system is a complex system involving numerous waste streams, collection schemes, treatment processes and various actors. Bus as well as many other systems, waste management is recently experiencing new and more sustainable development trends including the promotion of circular economy and increased material recycling. Hence there is a need for the implementation of an improved waste management system that requires a significant and thorough planning stage, the results of which will significantly depend on the availability of detailed information of the possible waste flows and waste composition. The aim of this paper is to experimentally determine and analyse the composition of unsorted municipal waste to provide assessment for incorporating waste composition analysis into further planning and modelling of a next generation waste management system in Latvia. The experimental results indicate that the unsorted municipal waste stream comprises of up to 32.9 % of recyclable materials and 29.2 % of biodegradable wastes. Thus almost 60 % of the waste currently being subjected to unsorted waste management system in Latvia could potentially be source separated ensuring higher quality of the recovered materials and promoting circular value chains. The results indicate a slight difference between waste composition in different waste management regions, thus noting that, in addition to the number of inhabitants and their habits, the local system in each waste management region may influence the composition of the collected wastes.
