Assessment of a residual municipal solid waste landfill for prospective ‘landfill mining’

Landfill mining is a prospective tool for the recycling of valuable materials (waste-to-material) and secondary fuel (waste-to-energy) from old, therefore more or less stabilised municipal solid waste landfills. The main target of Horizon 2020 ‘SMARTGROUND’ R&D was improving the availability and accessibility of data and information from both urban landfills and mining dumps through a set of activities to integrate all the data – from existing sources and new information retrieved with time progress – in a single EU database. Concerning urban landfills, a new sampling protocol was designed on the basis of the current Hungarian national municipal solid waste analysis standards, optimised for landfill mining. This protocol was then applied in a sampling campaign on a municipal solid waste landfill in Debrecen, Hungary. The composition and parameters of the landfilled materials were measured as a 12-year timescale. The total wet and dry mass of the valuable components possible for utilisation was estimated.

Solid Waste Landfills

The pollutants in the municipal solid waste landfill leachate result in severe damage to the environment of the groundwater and the soil beneath the municipal solid waste landfill. The liner systems with a low leakage performance are commonlly adopted under the municipal solid waste landfills to stop the contaminants of the leachate from polluting the environment. Even there are the rigorous demands in related specifications for the design of the liner system in the landfill. Pollution of the groundwater and the soil beneath the landfill still occurred in a large number of rubbish landfills because of the seepage. To investigate the influence of the compact clay layer (CCL) on the seepage performance of the liner systems, parametric analyses are conducted to study the influence of the thickness of CCL and the hydraulic conductivity of CCL on the leakage performance of the liner system. In conclusion, some suggestions for the design of the municipal solid waste landfills are proposed based on the analyses results.

Sampling Campaign

The scope of this paper is to present and compare the results of (1) an extensive odour, VOC and H2S impact assessment, and (2) a complete odour, VOC and H2S air quality monitoring program at a municipal solid waste landfill (MSWL). This study was conducted over a year, with an unprecedented amount of cross-assessment techniques and data points on a 1.3 million tonnes per year MSWL. All potential landfill emission sources were characterized for odours, VOCs, CH4 and H2S using a set of over 150,000 onsite samplings & measurements. An air quality monitoring program included continuous odour, CH4 and H2S monitoring, a 12-day-frequency VOC sampling campaign, and a 24h/7d odour survey at the nearest receptors. This paper will present the standardized methodologies used and comparative results from each independent assessment program.
