“…The age of the waste (4-9 years old) was confirmed by visual analysis of newspaper clippings and food bags. In this regard, it can be concluded that components of biogenic origin (wood, textiles, books and magazines with dense folded sheets) did not decompose completely during this time, whereas food waste as well as loose paper and cardboard did, so the proportion of landfill soil is lower compared to the results of earlier studies [8,21,22,31,32]. Accordingly, these research results confirm that as the waste ages, the proportion of landfill soil increases.…”

“…For example, in the results of studies [21] the component composition of solid fuel from excavated waste was determined as follows: films-29.4%, PET bottles-1.9%, other plastics and synthetic textiles-35.2%, leather-7.5%, wood-13.0%, paper-13.0%. The calorific value of solid fuel from excavated waste was determined experimentally and is equal to 21.5 and 23.6 MJ/kg [22]. Furthermore, thermal property studies [23,24] of "fresh" MSW made it possible to develop an algorithm for assessing the energy potential of heterogeneous flows, which can include landfill soil.…”

The paper presents results of field and laboratory studies of thermal characteristics to excavated landfill waste in Perm region, Russia. The peculiarity of the study includes the following aspects: waste composition with a high share of polymers, the climatic conditions of the territory and the lack of engineering infrastructure at the waste disposal facility. When determining the waste composition and thermal properties of waste, it is proposed to include a stage of removal of contamination from landfilled waste fraction, since their share of contamination can reach up to 33%. This stage will allow researchers to adjust the net calorific value of the excavated waste without overestimation, which may affect decision-making when implementing waste management technology. Among combustible components with the highest moisture content are waste paper (69.1%) and diapers (65.8%), whereas wood (11.2%), PET bottles (3.1%) and other 3D plastics (13.4%) have rather low ash content on a dry basis. Calculation of thermal properties and analysis of the energy potential of the waste samples was conducted based on the obtained data. The calorific value of the individual components and excavated waste depends not only on the moisture and ash content of the individual components, but also on the presence of contaminants. The average net calorific value of the excavated waste is 4.9 MJ/kg, and for the separate mixture of combustible components, it is 7.5 MJ/kg at a moisture content of 44%. Excavated landfill waste can be regarded as a resource for the manufacture of secondary fuel only after pretreatment that includes at least sorting and drying. The results of this study may be useful in developing technologies needed to eliminate old MSW dumps and old landfills, for the development of the concept of circular economy and prevention of environmental degradation problems.

“…Generally speaking, landfills and incineration are the most economical ways to dispose of waste from the government’s perspective, but due to the harm to the ecological environment and public health, they have been widely resisted and protested by the public. On the one hand, excessive landfills threaten water and soil safety, resulting in an increase in chronic diseases among nearby residents [ 25 , 26 ]. On the other hand, high carcinogens such as dioxins and residues produced by waste incineration also endanger public health [ 27 , 28 ].…”

Environmental pollution threatens public health and has become a social concern in recent years. Despite the conditions for public participation in environmental governance have improved considerably, the level of public engagement in government projects still falls short of expectations. Therefore, this article introduced two key variables, hoping to answer the following research question that how environmental concerns and governance performance affect public environmental participation. Through principal component analysis of the data from the “Survey of Chinese Urban Residents’ Attitudes toward Environmental Protection”, the findings of this article are as follows: First, public environmental concerns have no significant impact on their environmental engagement; second, the improvement of residents’ confidence in the government performance of environmental management reduces their willingness to participate in official projects. The higher the confidence in the government’s performance, the lower the level of public engagement is. Moreover, due to the consideration of self-interest or lack of environmental awareness, those who oppose waste incineration in waste terminal disposal tend to take a non-participatory role in waste sorting programs. Therefore, we suggest that the government have more diverse shareholders in environmental protection, so it should expand public participation through education, publicity, mobilization, and incentives.

“…The need for a deeper understanding of the physico-chemical properties of the fine fractions including their distribution across the different grain size fractions was also applied to shredder fine fractions [66]. Within the field of landfill mining, the general observations regarding the fine fractions were considered by authors of the SMARTGROUND project [67].…”

The EU Training Network for Resource Recovery through Enhanced Landfill Mining—A Review

2021

View full text Add to dashboard Cite

The “European Union Training Network for Resource Recovery Through Enhanced Landfill Mining (NEW-MINE)” was a European research project conducted between 2016 and 2020 to investigate the exploration of and resource recovery from landfills as well as the processing of the excavated waste and the valorization of the obtained waste fractions using thermochemical processes. This project yielded more than 40 publications ranging from geophysics via mechanical process engineering to ceramics, which have not yet been discussed coherently in a review publication. This article summarizes and links the NEW-MINE publications and discusses their practical applicability in waste management systems. Within the NEW-MINE project in a first step concentrates of specific materials (e.g., metals, combustibles, inert materials) were produced which might be used as secondary raw materials. In a second step, recycled products (e.g., inorganic polymers, functional glass-ceramics) were produced from these concentrates at the lab scale. However, even if secondary raw materials or recycled products could be produced at a large scale, it remains unclear if they can compete with primary raw materials or products from primary raw materials. Given the ambitions of transition towards a more circular economy, economic incentives are required to make secondary raw materials or recycled products from enhanced landfill mining (ELFM) competitive in the market.
