“…The use of mathematical modeling also allows for effective planning of waste management systems and assessment of the impact of changes in input parameters on the functioning of the system as a whole [25][26][27][28][29][30][31][32][33][34][35][36]. It has proved particularly useful in recent years in connection with the implementation of the circular economy concept [37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53]. Obviously, with the implementation of the circular economy concept, municipal waste will not disappear ("zero waste") and its amount will still depend on the standard of living of the inhabitants.…”

Municipal Solid Waste Mass Balance as a Tool for Calculation of the Possibility of Implementing the Circular Economy Concept

Municipal waste management system modeling based on the mass balance of individual waste streams allows us to answer the question of how the system will react to organizational changes, e.g., to the expected reduction in the amount of plastics or the introduction of a deposit for glass and/or plastic packaging. Based on the data on Polish municipal solid waste and the forecast of changes in its quantity and composition, as well as demographic data, a balance model was prepared to assess the impact of introducing higher and higher levels of recycling, in accordance with the circular economy assumptions on the waste management system. It has been shown that, for the Polish composition of municipal waste, even if the assumed recycling levels of individual streams are achieved, achieving the general target level of 65% recycling in 2025/30 may not be feasible. The possibility of achieving a higher level of recycling will be possible due the introduction of selective ash collection from individual home furnaces, while the impact of reducing the amount of plastics or introducing a deposit on packaging is minimal. The calculations also showed that, to complete the waste management system in Poland, we need at least 3.5 million Mg/year of incineration processing capacity and the present state (approx. 1.3 million Mg/year) is insufficient.

“…In a natural ecosystem, waste from one species is food to another, so matter and energy can circulate continuously. This same understanding can be observed in the urban environment where the transformation of waste into resources leads to a circular urban metabolism, closing the water, matter and energy cycle, and promoting sustainable communities (Ragossnig and Schneider 2019). As such, potential future alternatives that need to be explored include the stepwise reduction of land lling by the introduction of composting (Liikanen et al 2018), anaerobic digestion and mechanical-biological treatment (Mondal and Banerjee 2015).…”

This work presents the results of a comparative evaluation of two possible scenarios for Municipal Solid Waste (MSW) Management in Paraíba do Sul city - RJ - Brazil, using economic cost and sustainability indicators. The novelty of this work is in validating by means of cost and sustainability indicators the MSW management proposal that use of the organic fraction of waste in a local composting process. The first scenario, Simulated Scenario 1, which is currently being assessed by municipal management is: sending all MSW collected in the city to the new private landfill. The second scenario, Simulated Scenario 2, is a novel model proposed in this work, which involves the shipment of organic waste to a composting yard. The scenarios are examined on a case study composed of ten neighborhoods from the municipal core. The results obtained reveal a difference of less than R$ 10,000.00 per month between the total estimated costs for each scenario, with the second simulation being the most expensive. For the second scenario, there is the possibility of generating income through the sale of the compost, which could cover the excess cost. Insights from the score of the sustainability indicators show that the second scenario is the best from the environmental point of view. The technological simplicity and the low economic cost of the indicated method for composting are highlighted, as well as the existence of selective collection and the use of organic waste as the main advantages of Simulated Scenario 2.

“…Despite the growing presence of private players in the waste market since the late 1970s, public authorities have remained central actors in processing, collecting, regulating and co-funding waste infrastructures. The waste market was liberalized relatively recently, compared to telecommunications, energy, water and housing (Massarutto 2007;OECD 2000). The higher risks involved in waste investments for both public and private players slowed down full liberalization.…”

This article examines how the political economy of waste utility services is changing in response to circular economy programs. It focuses on the financial composition, economic position and geography of three sectors: waste recycling, incineration, and urban waste reuse. Building on an empirical analysis of these sectors in the Netherlands, specifically the Amsterdam city-region, it puts forward three key arguments. First, waste recovery corporations are becoming increasingly global and dependent on steady flows of waste. Second, incineration facilities play a central yet uncertain role in planning for the circular economy. Third, the circular economy is driving an emerging material reuse market in cities. The paper concludes by arguing that ongoing changes in waste markets run the risk of making (circular) economies even more dependent on wasteful consumption and production.
