“…Kůdela et al (2019) mainly focused on multi-stage models describing WtE plants and mechanical biological treatment in relation to the recycling targets of the EU and addressed the uncertainty of future waste generation. A greater emphasis was placed on WtE plants and transportation in the work of Hrabec et al ( 2020 ), where the authors described in more detail the design of the considered scenarios with respect to possible deviations in the prediction. Other recent studies within WM dealt with the Coronavirus pandemic.…”

In many countries, waste management is increasingly geared towards a circular economy, aiming for a sustainable society with less waste generation, fewer landfills, and a higher rate of recycling. Waste-to-Energy (WtE) plants, which convert waste into heat and energy, can contribute to the circular economy by utilizing types of waste that cannot be recycled. Due to the varying quality of sorting and socio-economic conditions in individual regions, the waste composition differs between regions and has an uncertain future development. Waste composition significantly affects the operation of WtE plants due to differences in energy potential. This paper supports strategic capacity planning for waste energy recovery by introducing a two-stage stochastic mixed-integer linear programming model that captures waste composition uncertainty through scenarios of possible future development. The results of the model provide insights into the economics of operation and identify important factors in the sustainability of the waste handling system. The model is demonstrated on an instance with six scenarios for waste management in the Czech Republic for the year 2030. The solution of the proposed model is to build 14 new WtE plants with a total capacity of 1970 kt in addition to the four existing plants with a capacity of 831 kt. The annual energy recovery capacity is expected to increase almost four times to satisfy EU directives that restrict waste landfilling.

“…This has necessitated the need for the development of optimization tools for environmental and technoeconomic assessments. Hrabec et al [30] proposed a robust two-stage integer non-linear program to develop the near-optimal waste allocation for its appropriate processing as well as waste transportation plan at an operational level. Rathor et al [31] formulated a mixedinteger non-linear program (MINLP) model to examine the use of collected organic MSW for producing biogas and then its application as a fuel in a thermal power plant to decrease the burden on coal mines.…”

Municipal solid waste (MSW) management has emerged as one of the major environmental challenges globally. The consequences of inappropriate waste management are manifold and the trend would continue if immediate interventions are not taken for its reversion amid rapid urbanization and current consumption patterns of individuals. The concept of circular economy (CE) can contribute to a paradigm shift in the transformation of the traditional linear approach that does not favour reuse, recycle, recovery concept. Modern and proven waste management practices with collection systems, recycling facilities, sanitary landfills, and waste-to-energy (WtE) and nutrient recovery offer opportunities to improve urban environment through the valorization of waste and by-products in a CE. This study scrutinizes the existing literature on the assessment of circularity and helps to develop a unified circularity framework in the management of MSW in cities. Key aspects such as tools for measuring circularity, nexus and trade-offs, and conditions in promoting CE are discussed. Finally, this paper elucidates the need for circularity, including enablers and inhibitors for promoting circularity in the management of MSW with a case study in the city of Curitiba, Brazil.

“…A key issue also for sustainable cities and communities is waste management. Circular Economy Implementation in Waste Management Network Design Problem: A Case Study ” (Hrabec et al 2019 ) presents a new approach to support strategic decision-making in the area of municipal solid waste management. The primary goal is to minimize waste residues for landfilling by reducing waste production, increasing recycling and using the resultant residual waste for energy recovery.…”
