  • Biodegradable Municipal Waste Management in Europe

     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 ...

  • Influence of the comminution of organic waste on their biodegradability

    Organic solids are present in very large quantities as products or waste from agriculture, food industry, household and many other fields. The disposal of organic waste can be realised using biological processes like anaerobic digestion or aerobic composting. The anaerobic digestion has advantages in comparison to composting such as a better handling of wet waste, the production of useful ...

  • Organic waste biodegradability test bio methane potential method

    Management Summary The biogas production from a mixture of food waste, garden waste, paper, napkins, plastic, metals and glass and anaerobically digested sludge was monitored until gas production had ceased. The homogenised biowaste mixture was subjected to two pre-treatment methods prior to being fed to the BMP reactors, these were: pasteurisation at 70oC ...

  • Extent and rate of biodegradation of different organic components in municipal solid waste

    Rates and extent of biodegradability of four different organic components of municipal solid waste (leaf litter, newspaper, magazine paper and A4 sheet) were evaluated under optimum conditions. Total solids (TS) removals in biotic samples ranged from 74.7% to 78.8% while volatile solids removals ranged from 75.7% to 84.8%. Significant biodegradation of tannin–lignin was observed for all four ...

  • Biodegradation Tests for Wastewater Samples

    Biodegradation Tests for Wastewater Samples Biodegradation tests usually involve comparison of the oxygen uptake of a test sample – or gas production for anoxic or anaerobic tests – to that for a readily biodegradable control substrate (usually acetic acid, ethanol, or aniline). While biodegradation characteristics can vary among chemical types and wastewater sources, typical patterns are shown ...

  • Environmental assessment of some non–biodegradable solid wastes along Vasai Creek of Mumbai

    The pollution problem due to non–biodegradable solid waste (NBDSW) along the Vasai Creek of Mumbai is one of the major issues which have remained totally neglected over past many years. The results of the present investigation indicates that plastics carry bags, milk/oil bags, plastic bottles, footwear and automobile tyres/tubes are some of the prominent NBDSW materials responsible for solid ...

  • Comparison of the methane production potential and biodegradability of kitchen waste from different sources under mesophilic and thermophilic conditions

    The methane production potential of kitchen waste (KW) obtained from different sources was compared through mesophilic and thermophilic anaerobic digestion. The methane yields (MYs) obtained with the same KW sample under different temperatures were similar, whereas the MYs obtained with different samples differed significantly. The highest MY obtained in S7 was 54%–60% higher than the lowest ...

  • 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 ...

  • 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 ...

  • Anaerobic biodegradability of fish remains: experimental investigation and parameter estimation

    The generation of organic waste associated with aquaculture fish processing has increased significantly in recent decades. The objective of this study is to evaluate the anaerobic biodegradability of several fish processing fractions, as well as water treatment sludge, for tilapia and sturgeon species cultured in recirculated aquaculture systems. After substrate characterization, the ultimate ...

  • Municipal solid waste - waste to energy conversion in India: an overview

    Municipal solid waste (MSW) is generated in enormous quantities, in India, causing environmental problems. It is collected primarily by sweeping in India and dumped on the outskirts of urban areas, which pollute the environment. Such MSWs also release methane and carbon dioxide, which are important greenhouse gases. MSW comprises biodegradable material. The MSW disposal methods in India mainly ...

  • Comparative in situ PET biodegradation assay using indigenously developed consortia

    A soil burial test was carried out to evaluate the biodegradation of polyethylene terephthalate under natural environment for a period of six months in presence of three different indigenously developed bacterial consortia. These consortia comprised of potential polymer-degrading bacterial cultures isolated from various waste disposal sites. The comparative biodegradation of PET samples in ...

  • Principles of Waste Avoidance and Utilization

    The minimization of wastes requiring disposal is increasingly important as available disposal options become more and more constrained, and particularly as more substances enter everyday use which are not readily decomposed in the natural environment and which can present long term hazards. This note sets out some basic principles for waste minimization in industrial processes, where ...

  • What’s next for food waste?

    With the target to halve edible food waste by 2020 drawing ever closer, a growing number of food manufacturers and retailers are improving their waste prevention strategies. But when ‘waste’ is inevitable, what then? Paul Featherstone, group director of SugaRich, investigates the extent to which such organisations are saying ‘no’ to landfill, before considering what ...

  • Renewable energy from food wastes

    Food waste is an untapped energy source that mostly ends up rotting in landfills, thereby releasing greenhouse gases into the atmosphere. Food waste is difficult to treat or recycle since it contains high levels of sodium salt and moisture, and is mixed with other waste during collection. Major generators of food wastes include hotels, restaurants, supermarkets, residential blocks, cafeterias, ...

  • Characterization of solid waste and determination of the emission potential

    Waste samples were taken in order to investigate the material behaviour regarding different treatment/recycling options. In waste incineration, the combustible and inert parts have to be determined. The content of biodegradable organic substances is important in biological treatment. The portion of biodegradable organic substance has also to be considered if wastes are to be landfilled. This ...

  • Biodegradation of phenol in refinery wastewater by pure cultures of Pseudomonas aeruginosa NCIB 950 and Pseudomonas fluorescence NCIB 3756

    The potential of microorganisms to catabolise and metabolise xenobiotic compounds has been recognised as a potentially effective means of toxic and hazardous wastes disposal. Phenol and its derivatives have long been recognised as some of the most persistent chemicals in petroleum refinery wastewaters, with high toxicity even at low concentrations. Biodegradation of these compounds has been ...

  • Cementatious considerations for medical waste solidification

    The most common cause for alarm in the medical field pertaining to waste disposal is the exposure of the worker to infectious wastes and contraction of diseases from these wastes. With the increased risk of exposure to blood borne pathogens in handling body fluids and disposal of items that have been tainted by these fluids, awareness and education for the prevention of percutaneous wounds is the ...
