“…Moisture content (W), as well as water field capacity, were slightly lower than the values usually measured for this type of waste (Di Lonardo et al, 2014;Pantini et al, 2015;Zach et al, 2000). Despite the waste underwent an aerobic treatment process in the MBT plant, the organic matter of waste is still quite high, as confirmed by VS, TOC and COD contents.…”

All over Europe, MBT facilities can apply different combinations of mechanical sorting, bio-drying, and biological processes depending on the specific target, that may be a pre-treatment before incineration or a pre-treatment to produce a bio-stabilized product that has a lower impact when disposed of in landfills (Adani et al, 2004;Di Maria et al, 2013;Farrell and Jones, 2009;Montejo et al, 2013).…”

“…This stage leads to two distinct flows: the oversize fraction, which is further processed to produce refuse-derived fuel, and the undersize fraction, rich in organic putrescible matter, which is biologically treated using an anaerobic/aerobic process in order to stabilize it. The main distinction between different MBT systems concerns the sequence of process steps and the type and duration of the biological treatment (Pan and Voulvoulis, 2007;Pantini et al, 2015). The specific technology and process applied may strongly affect the long-term behaviour of MBT wastes in landfills in terms of both liquid composition and gas generation (Boldrin et al, 2011;Siddiqui et al, 2013).…”

Assessment of biogas production from MBT waste under different operating conditions

In this work, the influence of different operating conditions on the biogas production from mechanically-biologically treated (MBT) wastes is investigated. Specifically, different lab-scale anaerobic tests varying the water content (26-43% w/w up to 75% w/w), the temperature (from 20 to 25°C up to 55°C) and the amount of inoculum have been performed on waste samples collected from a full-scale Italian MBT plant. For each test, the gas generation yield and, where applicable, the first-order gas generation rates were determined. Nearly all tests were characterised by a quite long lag-phase. This result was mainly ascribed to the inhibition effects resulting from the high concentrations of volatile fatty acids (VFAs) and ammonia detected in the different stages of the experiments. Furthermore, water content was found as one of the key factor limiting the anaerobic biological process. Indeed, the experimental results showed that when the moisture was lower than 32% w/w, the methanogenic microbial activity was completely inhibited. For the higher water content tested (75% w/w), high values of accumulated gas volume (up to 150Nl/kgTS) and a relatively short time period to deplete the MBT waste gas generation capacity were observed. At these test conditions, the effect of temperature became evident, leading to gas generation rates of 0.007d(-1) at room temperature that increased to 0.03-0.05d(-1) at 37°C and to 0.04-0.11d(-1) at 55°C. Overall, the obtained results highlighted that the operative conditions can drastically affect the gas production from MBT wastes. This suggests that particular caution should be paid when using the results of lab-scale tests for the evaluation of long-term behaviour expected in the field where the boundary conditions change continuously and vary significantly depending on the climate, the landfill operative management strategies in place (e.g. leachate recirculation, waste disposal methods), the hydraulic characteristics of disposed waste, the presence and type of temporary and final cover systems.

This paper reviews the role of sanitary landfills in current and future waste management strategies based upon the principles and the goals established by the European Framework Directive on Waste (2008/98/EC). Specific reference is made to studies of our research group regarding new tools developed to evaluate leachate production, taking into account the different characteristics of municipal solid waste (MSW). Laboratory leaching tests and a methodology proposed to interpret the results are described and discussed, as well as tools developed to estimate landfill leachate production. Residual flows produced by mechanical-biological treatment (MBT) plants, mainly Solid Recovered Fuel (SRF) and Stabilized Organic Waste (SOW), incineration and composting plants are considered in particular. Experimental results showed that the most suitable end-uses or disposal options for the outputs of waste treatment plants are site-specific and should be defined on the basis of a detailed characterization. The application of the model developed to assess landfill leachate production showed a very good agreement with field data.
