“…3 and 4). As presented in Table 2, changes in the chemical composition of the leachate from the biologically treated and untreated waste confirmed that the initial aerobic treatment of waste before storage helps to reduce the emissions of concentrations of organic pollutants in leachate and methane production, as well as to establish stable methane conditions more quickly [14].…”

“…On the other hand, the high methane production observed in the stable phase of methane fermentation in the I II III IV I II III IV I-IV I- ST reactor indicates a partial breakdown of the complex organic substances that are difficult to degrade, which remain after initial aerobic treatment. The dominant organic components in the waste are: cellulose 50 %, lignin 15 %, hemicellulose 10 %, protein 5 %, and starch, pectin, and other soluble sugars [14]. The main sources of carbon, used by methane microorganisms, are cellulose and hemicellulose, which are classified as materials that are difficult to degrade under anaerobic conditions.…”

The efficiency of waste degradation can be expressed by the rate of waste decomposition in individual phases. This article presents the durations of degradation phases of pretreated and untreated waste stabilized in anaerobic laboratory reactors. In this investigation, the quantities of organic and nitrogen contaminants emitted from the waste during the study are presented. The study confirmed the beneficial effects of aerobic pretreatment of waste before landfilling on reducing the duration of hydrolysis and acid phases, and speeding up the start of the stable methane phase. In the pretreated waste reactor, the stable methane phase began about 19 weeks earlier than in the untreated waste. The total amounts of contaminants removed from the aerobic pretreatment waste were lower than from untreated waste, with values of COD, TOC, BOD 5 , and VFA corresponding to 21, 18, 6, and 23 %, respectively, and values of TKN and NH 4 of 7 and 50 %, respectively.

“…Previous studies (AEA, 2001;ERM, 2006;Arena et al, 2003;Bockreis and Steinberg, 2005) assessed MBT plants that incorporated aerobic biological treatment or composting that bio-stabilise the waste and thus they assumed that landfilled residues have not significant climate change impact. However, in this study the MBT involves bio-drying that either does not reduce the biodegradation potential of the waste or it reduces it only by a small amount (Adani et al, 2002;Sugni et al, 2005).…”

“…Biogas and leachate characteristics of pretreated waste based on small scale studies have been reported by a few authors (e.g. Bayard et al [3]; Bockreis and Steinberg [4]; Horing et al [5]; Leikam and Stegmann [6]). These studies demonstrate that MBT waste has reduced gas generating potential and leachate strength.…”

One of the main aims of the EU Landfill Directive is to reduce significantly the landfilling of biodegradable municipal waste. Mechanical-biological pretreatment of municipal solid waste has become popular and is often adopted to enable compliance with this requirement of the Landfill Directive. This will have major implications for the nature of the waste that is disposed of to landfills and hence for the way in which the landfills should be managed. Pretreatment will cause changes in the composition and properties of the waste going to landfills including the gas generating potential, leaching behaviour and settlement characteristics. Germany has set strict allocation criteria for landfilling of mechanically biologically treated (MBT) waste. In contrast, there are no standards for MBT waste in the UK. Experimental studies were conducted to investigate the biodegradation and settlement behaviour of MBT waste samples treated to typical UK and German standards. The performance of large scale consolidating anaerobic reactors was monitored in terms of gas generating potential, leaching behaviour and waste settlement. The contributions of mechanical creep and biodegradation to secondary settlement were also identified.
