  • Biodegradation of methane and halocarbons in simulated landfill biocover systems containing compost materials

    The attenuation potential of methane (CH4) and of selected volatile organic compounds (VOCs) was compared in four types of compost materials using dynamic flow column experiments over a period of 255 d. Garden waste compost mixed with wood chips showed the highest steady-state CH4 oxidation rate (161 g m–2 d–1), followed by a commercial compost product Supermuld (110 g m–2 d–1). In the column ...

     This report is intended as guidance to help decision-makers in their efforts to comply with the EU Landfill Directive's targets for reducing the landfilling of biodegradable municipal waste. The first two parts of the report provide information on the strategies and instruments available to achieve this goal while the third part focusses on technology and market ...

  • Aerobic co-treatment of landfill leachate and domestic wastewater – are slowly biodegradable organics removed or simply diluted?

    This study investigated the co-treatment of landfill leachate/domestic wastewater in bench-scale activated sludge (AS) reactors to determine whether the slowly biodegradable organic matter (SBOM) was removed rather than diluted. The AS reactors were loaded with mixtures of raw leachate and leachate that was pretreated by air stripping. The tested volumetric ratios were 0%, 0.2%, ...

  • Southwest landfill case study

    The Problem: A landfill located in Texas was experiencing high concentrations of ammonia in the leachate from their domestic landfill. Compliance standards were becoming more stringent at the same time ammonia and BOD levels in the leachate stream were increasing in concentration. The Solution: After on‐site testing ...

  • Monitoring And Analysis of Landfill Gases

    CoGDEM is the trade association representing manufacturers and service providers who are active in the field of gas detection instrumentation and environmental monitoring apparatus. Crowcon Detection Instruments Ltd was one of the founding members of CoGDEM, and in this article their Product Manager of Fixed Systems, Andy Avenell, gives an update on Landfill Gas. Landfill is by far the most ...

  • Sequential treatment of an old-landfill leachate

    This work investigates the performance of combined techniques applied to the treatment of an old-landfill leachate, which presents high salinity, low biodegradability (BOD5/COD around 0.05) and high ammonia concentration. Three sequences of processes were employed, including coagulation/flocculation, chemical oxidation, biological treatment and ammonia stripping. The association of ...

  • Green labels: The walk behind the talk - `Biodegradable`

    The word “biodegradable” is probably one of the easiest green labels to understand, so one may assume it is also the least likely to be subject to false claims. However, the term is still interpreted very loosely and frequently used on products that are toxic, that break down into harmful environmental contaminants, or that can take many decades, even centuries, to decompose. On top ...

  • Treatment of landfill leachate by effective microorganisms

    Five dominant strains, capable of treating leachate effectively, were isolated. The results showed that the removal efficiency of COD by using the mixed strains was higher than the pure strain, reaching 46.8%. The optimal inoculum concentration and the treatment time were 10.0% and 120 h respectively. The removal rate of COD reached the maximum at the temperature of 35°C and pH of 7.0. The ...

  • Fungi immobilization for landfill leachate treatment

    This paper investigated treatment of landfill leachate collected from Nonthaburi landfill site, Thailand, by using immobilized white rot fungi, namely, Trametes versicolor BCC 8725 and Flavodon flavus BCC 17421. Effects of pH and co-substrates were investigated at different contact times. Three types of co-substrates as carbon source used in this study are glucose, corn starch ...

  • Temperature–dependent polylactic acid (PLA) anaerobic biodegradability

    Polylactic acid (PLA) biodegradability is mostly claimed according to PLA biodegradation behaviour under aerobic composting conditions. However, waste materials containing PLA are frequently disposed of in municipal landfills, which are operated anaerobically. PLA anaerobic sludge digestion results are acquired to elucidate effects of the degrading temperature on PLA biodegradation. When the ...

  • TCE at Department of Defense Landfill Site

    PROJECT BACKGROUND Subsurface investigations at this 40-acre Northern California Department of Defense (DOD) landfill site revealed elevated levels of TCE in site soils and groundwater. This discovery was made through routine site monitoring, as regulated by the state of California solid waste landfill regulations. Regulators required site cleanup to reduce chlorinated hydrocarbon concentrations ...

  • Degradation of biodegradable plastics under controlled composting conditions

    The management of solid waste is a growing concern in many countries. Municipal solid waste is a major component of the total solid waste generated by society, and the fraction of municipal solid waste made up of plastic materials continues to increase. The composting of plastic materials along with organic wastes will help society to usefully recycle more of its solid waste and divert it from ...

  • Florida hospital complex goes green with recycling, biodegradable programs

    For Earth Day 2009, Rob Lester really had something special to celebrate. Just one year after launching a biodegradable project at Florida’s Ocala Regional Medical Center and West Marion Community Hospital, some 1.5 million Styrofoam cups, bowls and plates and plastic utensils are no longer being sent to the landfill. That program has proven so successful that the 200-bed medical center and its ...

  • Stabilisation of municipal solid waste in bioreactor landfills - an overview

    The basic purpose of operating landfills as bioreactors is to enhance the waste degradation and to stabilise the waste in shorter time period as compared to conventional dry tomb landfills. This paper presents an overview of bioreactor landfills in terms of various factors affecting stabilisation of municipal solid waste. Moisture is considered to play a critical role in the biodegradation of the ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • A laboratory study on stabilization criteria of semi-aerobic landfill

    The semi-aerobic landfill has been widely used as a sustainable landfill technology. However, the stabilization indicator system and stabilization criteria of semi-aerobic landfill have not been developed yet. In this study, the stabilization indicator system and stabilization criteria of semi-aerobic landfill were studied on the basis of simulation tests and a mathematical method. The results ...

  • Modelling methane and vinyl chloride in soil surrounding landfills

    Sanitary landfilling is used in many countries as a preferred method for disposal of household wastes for reasons of simplicity and economics. Immediately following its deposition within a landfill, most of the organic fraction of waste will begin to undergo degradation through chemical and bacterial action. Landfill gas (LFG) is a product of biodegradation and consists of primarily methane ...
