“…The moisture content is also important when considering the recycling of wastes to produce energy through biological or thermal methods (Brunner and Rechberger, 2015). In addition, it increases the dissolution of the organic and the inorganic of different chemical compounds like metals and hence increases the leaching of these compounds to the environment like water recipients (Qi et al, 2013). According to different studies, the wastes moisture content in Europe and USA ranged between 20% and 30%, while it is between 30% and 60% in China (Hull et al, 2005; Meng et al, 2012; Sormunen et al, 2008).…”

Characterisation of excavated fine fraction and waste composition from a Swedish landfill

et al. 2016

The present research studies the characterisation and the physico-chemical properties of an excavated fine fraction (<10 mm) from a Swedish landfill, the Högbytorp. The results showed that the fine fraction represents 38% by mass of the total excavated wastes and it contains mainly soil-type materials and minerals. Higher concentrations of zinc, copper, barium and chromium were found with concentrations higher than the Swedish Environmental Protection Agency (EPA) for contaminated soil. The found moisture and organic contents of the fine fraction were 23.5% and 16.6%, respectively. The analysed calorific value (1.7 MJ kg), the potential of CH (4.74 m t dry matter) and Total Organic Carbon (TOC) (5.6%) were low and offer low potential of energy. Sieving the fine fraction further showed that 80% was smaller than 2 mm. The fine represents a major fraction at any landfill (40%-70%), therefore, characterising the properties of this fraction is essential to find the potential of reusing/recycling or safely redisposing.

“…Studies have been identifying the health and the environmental harmful effects of the landfill green house gases and leachates [5,6]. Consequently, the reason for mining landfills might be also to stimulate the remediation of these sites and reducing management cost [7].…”

A B S T R A C TLandfills represent a continuous environmental threat due to the emission of different greenhouse gases, which are mainly responsible for the climate changes, and the contaminated leachate that affects the surface and ground water recipients. The circular economy approach appeared as a useful solution to reduce the depletion of the Earth's natural resources and the environmental risk effects by considering all of the lost resources like wastes including the landfills as potential secondary resources. It is well known that characterizing the composition of landfill waste is an essential step in specifying the recycling methods. In the current research the waste composition at one of the first EU regulationscompliant sanitary landfills (the Torma landfill in Estonia) was studied. The results showed that the fine fraction (<20 mm) represented 53% of the total excavated waste materials while the waste to energy fraction (plastics, woods etc.) was the highest within the coarse fraction (>20 mm). The present work emphasized that mining landfills can be a good solution either for extracting primary raw materials like metals, as a source for recovering energy, or for acquiring landfill space.

“…Soil cover with low permeability can reduce the filtration of leachate through waste thus minimizing the migration of toxic pollutants, including heavy metals [5]. It also has been studied that municipal solid waste biostabilization was related to intermediate soil cover characteristics that controlled the decomposition rate of waste [6].…”

A B S T R A C TThis batch study focuses on suitability of laterite soil-pressmud as daily soil cover of landfill. The laterite soil samples were mixed with waste from sugar refinery process, namely pressmud at different percentages of weight ratio (10, 30 and 50%). The batch equilibrium tests were carried out and glaringly showed that the laterite soil-pressmud mixtures have the capability to remove more than 62% of Cr, Cu, Mn, Ni, Pb and Zn concentration in leachate. Meanwhile, the removal efficiency of heavy metals from leachate in the laterite soil alone was lower than 50%. Pressmud alone however showed more than 53% removal. The laterite soil-pressmud mixtures, particularly at 30 and 50 percent of pressmud signify great potential as daily soil cover in reduction of heavy metals migration in landfill leachate.
