Abstract
Densely populated areas with large incoming populations have difficulty achieving high separate collection rates of municipal solid waste. The manuscript analyzes the link between biowaste collection and circular economy requirements as a fulfilment of the recycling rates and using biogas as a sustainable energy source. Three biowaste collection scenarios and three technical scenarios for its treatment are considered. The first scenario assumes only composting for biowaste treatment, the next includes also anaerobic digestion. In the years 2020–2050, the separate biowaste collection level will increase, depending on the scenario, from 26.9 kg/inh. up to 148.1kg/inh. By 2030, the quantity of biogas generated from biowaste can grow to almost 9 million m3/year, enabling the production of renewable energy at annual levels of almost 17 GWh and 69 TJ. Using the third scenario, the quantity of biogas generated grows more than twice (in 2035). If the capture rate of biowaste increases from 15% to 20% and then to 25%, the quantity of biogas generated grows by, respectively, 65% and more than 100%. Unfortunately, none of the scenarios enables the required municipal solid waste recycling rates in 2030 (60%) and 2035 (65%), which demonstrates the significant need to develop more effective separate collection systems, including biowaste. Methodology applied in the paper can be used for other cities and regions trying to meet circular economy demands.
Highlights
The management of Municipal Solid Waste (MSW) still continues to be a significant challenge in all the states of the European Community and is an important element in the transition to CircularEconomy (CE) [1]
In amending a package of Directives in order to implement the CE principles into European Union law, including the Waste Framework Directive and the Landfill Directive [3,4], a good deal of attention was paid to the Organic Fraction of Municipal Solid Waste (OFMSW), which is an important element in the planning of the sustainable MSW management system [5]
The analysis conducted shows the challenges that countries that are just introducing biowaste collection face in the 10 years in order to meet the requirements of CE for 2030 and 2035
Summary
The management of Municipal Solid Waste (MSW) still continues to be a significant challenge in all the states of the European Community and is an important element in the transition to CircularEconomy (CE) [1]. The management of Municipal Solid Waste (MSW) still continues to be a significant challenge in all the states of the European Community and is an important element in the transition to Circular. In the case of MSW, an important aspect of the implementation of the CE assumptions is a plan for reducing their weight deposited at landfills and enhancing the share of waste, which can be returned to the system by material and organic recycling [2]. In amending a package of Directives in order to implement the CE principles into European Union law, including the Waste Framework Directive and the Landfill Directive [3,4], a good deal of attention was paid to the Organic Fraction of Municipal Solid Waste (OFMSW), which is an important element in the planning of the sustainable MSW management system [5]. International experiences, including countries such as China, India and Americas, show successful attempts to implement many technologies of valuable use of OFMSW
