This research investigated the effect of leachate recirculation and storage operation in tropical landfill. Four lysimeters were operated under conventional landfill operation, leachate re-circulation, leachate storage with re-circulation and internal storage modes. Organic waste degradation, leachate quantity and characteristics and well as methane gas from each lysimeter were compared. Leachate ...
This forum outlines the achievement of a zero waste approach which took ten years to fulfill in a condominium complex in a city with 650,000 inhabitants situated in central Brazil.Keywords: zero waste, waste management, biodegradables, recycling, landfill, ...
Throughout the world, there have been increasing interests in the recycling of wastes for sustainable development. This especially applies for organic materials of municipal and agro-industrial origin. Recycling initiatives in Argentina are still incipient. In the last years, the use of earthworms for stabilising organic wastes has been evaluated. In this paper, the authors compile the research ...
In most countries, the majority of household solid waste is landfilled because of associated low capital, operation and maintenance costs. However, many existing landfills have exhausted their handling capacities and new facilities are faced with the problem of siting. Alternatives to traditional landfill practice are required to achieve sustainability in managing solid waste. This manuscript ...
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 ...
With landfill at the bottom of the European waste hierarchy, policies to divert waste from landfill play a very important role within European and national waste policies. This report analyses the effectiveness of implemented policies on the diversion of total municipal waste and biodegradable municipal waste from landfill in the context of the 1999 EU Landfill Directive and other relevant ...
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 followed by anaerobic digestion ...
ABSTRACT The focus of the EU landfill directive is the reduction of biodegradable waste destined for landfill on a solely quantitative basis. Trials on the bio-mechanical treatment and its effect on the landfill behaviour show that the quality of the remaining organic fraction for landfilling should be considered because it is is more relevant than the quantity of biodegradable waste, in terms ...
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 ...
The increase in quantum of Municipal Solid Waste (MSW) generation puts additional burden on MSW and energy management. Out of all the wastes, the biodegradable waste is the worst waste regarding heat generation due to anaerobic conditions of the waste. The expenditure on collection, transportation and disposal of MSW are very high and environmentally unhygienic. The waste can be converted into ...
Landfill gases, predominantly methane and carbon dioxide, are produced by the biodegradation of organic wastes. Biodegradation occur, if the water comes in contact with the buried waste. Techniques such as clay capping are used to minimise percolation of water into the landfill, or gas collection system installed to reduce methane emission into the atmosphere. The use of clay cap has proven not ...
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 ...
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 ...

Currently, Indian cities generate waste which is being disposed in its outskirt as open dumping. This approach affects health and life of people living at city outskirts. A paradigm shift is required in the approach to waste management. Waste management policy should aim at scientific processing of waste within the city itself. This paper highlights policy framework towards management of ...
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 ...
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 ...
Location: Vancouver, B.C. Description: A biorecovery facility was seeking to use its product as animal feed supplement. The facility treats biodegradable wastes using an Autothermal Thermophilic Aerobic digestion (ATAD) process. The ETV verification program involved developing a sampling protocol followed by a sampling program that included extensive analytical testing plus solids screening ...
AbstractA large number of different processes are today on the market for treatment of biodegradable waste. The two principal biological treatment methods available are aerobe treatment (composting) and anaerobe treatment (digestion/fermentation). In Norway so far, aerobe treatment has been the most popular solution. Both windrow composting and tunnel composting systems are in use. The first ...
