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 ...

The physical, chemical and microbial characteristics of biodegradable municipal waste derived composts

A comparative study of the physical, chemical and microbial properties of 12 composts sourced from United Kingdom commercial composting plants was carried out. The aim was to ascertain whether these composts could be used as growing media or for application to agricultural land. The composts were produced from either source segregated biodegradable municipal waste (BMW) or mixed municipal solid ...

Review of Selected Waste Streams: Sewage Sludge, Construction and Demolition Waste, Waste Oils, Waste from Coal-fired Power Plants and Biodegradable Municipal Waste

Five waste streams are reviewed in this technical report: sewage sludge, construction and demolition waste, waste oils, waste from coal-fired power plants and biodegradable municipal waste. The review focuses on the quantities of wastes produced and on systems used to collect and treat them in several European countries and ...

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 ...

Characterisation of the recalcitrant organic compounds in leachates formed during the anaerobic biodegradation of waste

This study investigates the use of UV absorption and fluorescence spectroscopy to assess the early development of recalcitrant organic compounds in leachates formed during the anaerobic biodegradation of municipal solid waste. Biochemical methane potential tests were carried out on fresh waste (FW) and composted waste (CW) over a period of 150 days and leachates produced from the degradation of ...

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 ...

The use of methanotrophic applications to control of fugitive methane emissions from the biodegradation of organic waste

Large amounts of methane (CH4) escapes to the atmosphere through fugitive emissions arising from anthropogenic sources. This is detrimental because the Global Warming Potential (GWP) of CH4 is 25 times that of carbon dioxide (CO2) on a 100 year time horizon. As a result, there has been increasing ...

Study on accumulation of non–biodegradable solid wastes along Ulhas River of Thane, Mumbai

With the spread of technology, industrialisation and increasing standards of living, the accumulation of non–biodegradable solid waste (NBDSW) is an unwelcome and often unnoticed side effect of 'development' in India. Therefore in the present investigation, attempts are made to quantify major non–biodegradable solid wastes viz. plastics, synthetic rubber and glasses which are accumulated at three ...

Remscheid pilot project: evaluation of a large scale trial of utilizing biodegradable waste bags for biowaste collection and treatment

Separate collection of organic waste may be considered as an integral part of contemporary waste management schemes. In this function it became widely accepted in the last ten years. It pursues the idea of a recycling economy according to the European hierarchy of waste - prevent, reduce, recycle - and is aimed at closing nutrient cycles. Nevertheless, separate collection at source essentially ...

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 ...

Cyanide removal by combined adsorption and biodegradation process

Cyanide is present in environmental matrices and waste streams as simple and complex cyanides, cyanates and nitriles (Ebbs, 2004). Cyanide compounds are extensively used in industry and their effluents are the major source of these toxic pollutants in our environment (Desai and Ramakrishna, 1998). The release of cyanide from industries worldwide has been estimated to be more than 14 million kg/yr ...

$Sources and levels of potentially toxic elements in the biodegradable fraction of autoclaved non-segregated household waste and its compost/digestate$

Sources and levels of potentially toxic elements in the biodegradable fraction of autoclaved non-segregated household waste and its compost/digestate

Waste that reflected the average UK composition of household waste was treated by autoclaving at the three set pressure/temperature levels of 2.7 bar/130 °C, 6.2 bar/160 °C and 15.5 bar/200 °C. The biodegradable fraction of the autoclaved household waste ('floc') was manually separated by screening and underwent characterization for its Cd, Cr, Cu, Pb, Hg, Ni, and Zn content. Autoclaving did not ...

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 ...

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 ...
