“…In Turkey, many studies have intensively examined municipal solid waste management (Ayvaz-Cavdaroglu et al, 2019; Banar et al, 2009; Coban et al, 2018; Tınmaz and Demir, 2006; Turan et al, 2009; Rızvanoğlu et al, 2019). Furthermore, some researchers studied liquid waste (Gurbuz and Ozkan, 2019), medical waste management (Birpınar et al, 2009), hazardous waste (Utku and Erol, 2020; Yayintas et al, 2007) and food waste (Cakar et al, 2020).…”

Zero waste has an important position in the circular economy model in terms of manufacturing recyclable products instead of products to be consumed quickly, reducing the amount of waste, developing and implementing recycling/reuse technologies, and thus ensuring resource efficiency. A zero-waste strategy is one of the basic steps to achieve the goal of the circular economy. The number of studies conducted on Turkey’s zero waste management strategies referring to the circular economy is quite limited. To fill this gap in the literature, this study aims to identify the potential barriers which have an important role in zero waste management practices in Turkey. Through a broad literature review and expert opinions, 12 key barriers for zero waste implementation in Turkey have been defined in view of circular economy principles. Then, fuzzy DEMATEL methodology is employed to examine which is the most influential barrier affecting zero waste management success and to identify the interdependence of these barriers. The results indicate that uncertainty of the goals and tactics relevant to the circular economy and lack of financial and economic aid are key causal barriers that affect Turkey’s zero waste management.

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

2021

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.

“…Pappu et al reported that about 960 million tonnes of solid wastes are being produced per annum in India alone among which 350 million tonnes are organic wastes; 290 million tonnes are inorganic or industrial wastes. A number of successful investigations have been conducted in the past regarding the recycling and management of municipal wastes . However, some biodegradable industrial wastes, including sludge from the textile industry, leather mill solid waste, baggage of the sugarcane industry, paper mill waste, wastes from agro mills, thermal power plant waste, gaur gum industrial waste, and so on, are also taken into consideration by the previous researchers for their gainful utilization in the preparation of vermicompost to convert them into organic fertilizers.…”

Processing and wear response study of glass‐polyester composites with waste marble dust as particulate filler

Proper management of any waste lies in using its potential in the development of some value added products. In line with this, the present research has explored the use of marble dust, an industrial/construction waste as a secondary filler in the glass‐polyester material system to prepare wear‐resistant hybrid composites. Such hybrid composites are fabricated through a simple hand layup route. The composites are characterized in regard to their density and porosity. Mechanical properties, such as tensile and flexural strength, are evaluated under controlled laboratory conditions. Dry sliding wear trials are conducted under different test conditions using a pin‐on‐disc test rig as per ASTM G 99‐05 following Taguchi's L25 orthogonal array. Significant control factors influencing the specific wear rates (SWRs) are identified and an optimal factor setting based on minimum wear is found out. Scanning electron microscopy of the worn composite surfaces is done to ascertain the possible wear mechanisms. Analysis revealed that the incorporation of filler helps in reducing the wear rate of the composites. Thus, the wear resistance of glass‐polyester composites is improved significantly by the incorporation of marble dust. Furthermore, a prediction model based on artificial neural networks is developed to estimate the SWR within and beyond the experimental domain.
