“…Various types of models were used-regression [19,20], stochastic [21,22] or with the use of artificial neural networks [23,24], often with good results, close to reality. 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].…”

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.

Future improvements on performance of an EU landfill directive driven municipal solid waste management for a city in England

Sustainable municipal solid waste (MSW) management is regarded as one of the key elements for achieving urban sustainability via mitigating global climate change, recycling resources and recovering energy. Landfill is considered as the least preferable disposal method and the EU Landfill Directive (ELD) announced in 1999 requires member countries to reduce the volume of landfilled biodegradable materials. The enforcement of ELD initiated the evolution of MSW management system UK. This study depicted and assessed the transition and performance of MSW management after the millennium in Nottingham via materials flow analysis (MFA), as well as appropriately selected indicators based on the concept of waste management hierarchy and targets set in waste management regulations. We observed improvements in waste reduction, material recycling, energy recovery, and landfill prevention. During the period 2001/02 to 2016/17, annual waste generation reduced from 463 kg/Ca to 361 kg/Ca, the recycling and composting share increased from 4.6% to 44.4%, and the landfill share reduced from 54.7% to 7.3%. These signs of progress are believed to be driven by the ELD and the associated policies and waste management targets established at the national and local levels. An alternative scenario with food waste and textile separation at source and utilizing anaerobic digestion to treat separately collected organic waste is proposed at the end of this paper to fulfil the high targets set by local government and we further suggest that the recycling share may be improved by educating and supporting the public on waste separation at the sources.

ABSTRAKKegiatan daur ulang sampah di Kota Semarang dapat dilakukan dengan cukup baik berkat campur tangan dari sektor informal. Sayangnya, kegiatan pengelolaan sampah formal tidak mempertimbangkan nilai pemulihan sampah. Penelitian ini bertujuan untuk mengidentifikasi aliran sampah plastik di sektor informal di Kota Semarang. Peneliti menggunakan wawancara mendalam untuk mengumpulkan data. Ada 46 agen daur ulang, termasuk lima (5) pemulung, 17 pengepul 20 perusahaan skala kecil, tiga (3) perusahaan skala besar, dan 1 perantara (pabrik penggilingan plastik) yang telah diwawancarai. Data dari Badan Lingkungan Hidup Kota Semarang digunakan sebagai data sekunder. Hasil penelitian menunjukkan bahwa jumlah sampah plastik yang dihasilkan oleh masing-masing agen daur ulang diperkirakan 23,98 kg/ hari di tingkat pemulung, 54,74 kg/ hari di tingkat pengepul, 347,48 kg / hari di tingkat perusahaan skala kecil, 1.735,3 kg / hari di tingkat perusahaan skala besar, dan 2.160 kg / hari di tingkat perantara. Produsen bijih plastik daur ulang berlokasi di luar Kota Semarang, sedangkan bank sampah berbasis masyarakat adalah bagian dari pengelolaan sampah berbasis masyarakat yang tidak mencari keuntungan. Oleh karena itu, tidak dibahas secara mendalam di penelitian ini.Kata kunci: sampah plastik, aliran sampah, agen daur ulangABSTRACTWaste recycling activities in Semarang City can be conducted quite well due to the interference of the informal sector. Unfortunately, the formal waste management activities do not consider the utilization of waste recovery value. This study aims to identify the flow of plastic waste in the informal sector in Semarang City. We used in-depth interviews to collect data. There are 46 recycling agents, including five (5) scavengers, 17 scrap dealers, 20 small scale enterprises, three (3) large scale enterprises, and 1 intermediate (plastic grinding mill) that has been interviewed. Data from The Environment Agency of Semarang City obtained as secondary data. The results showed that the amount of plastic waste generated by each recycling agent was estimated at 23.98 kg/day at the scavenger level, 54.74 kg/day at the scrap dealer level, 347.48 kg/day at the small scale enterprise level, 1,735.3 kg / day days at large scale enterprise level, and 2,160 kg/day at the level of plastic waste intermediates. Recycled plastic ore producers are located outside Semarang City, whereas the community-based waste bank is part of community based solid waste management that is not looking for profit. Hence, it is not discussed in depth in this study.Keywords: plastic waste, waste flow, recycling agent
