Odour pollution problems caused by composting activities in flanders: current situation and abatement strategies
In Flanders, garden fruit and vegetable (GFV) waste is selectively collected and composted in 7 composting plants, in six of which aerobic indoor composting is used. In the seventh plant waste is anaerobically digested first followed by an aerobic post-treatment. The total amount of waste composted was about 275 000 tons in 1997 (OVAM, 1999). The nominal capacity of the composting plants varies ...

Perspectives on organic waste recovery relative to composting and anaerobic digestion
Generally speaking, organic waste renders its self suitable for recovery purposes owing to the nutrient elements it contains and the energy stored in the biochemical bonds of its constituent organic compounds. Both composting and anaerobic digestion (AD) have been used since a long time ago in reclaiming organic material. It seems that the first modern composting process was developed in 1920s ...

Prison Produces Proper Professional Product
Earlier this year the States of Jersey Prison Service, located on the South West hilltop coastline of Jersey took to recycling their food and green waste at the prison with an A900 Rocket Composter and Dehydra dewatering system, which was supplied and installed by Tidy Planet. The project has proved a Triumphant success thanks to the forward thinking and enthusiasm shown by the team on site and ...

Composting in flanders: the vlaco experience
Currently, the Flanders waste policy is based on the so-called ‘ladder of Lansink’. Six aerobic composting and one anaerobic digestion plant are operational for the treatment of biowaste. Some new composting plants are foreseen for 1999 and/or 2000. Composting retention time varies from 10 to 15 weeks. Green waste is treated in 15 open air composting plants. With respect to the use of compost ...

Kinetic study of compost liquor nitrification
This study is a first kinetic approach about the compost liquor treatment by activated sludge. This industrial wastewater is highly loaded in organic and nitrogen compounds (COD≈12,000 mg L−1 and NH4+-N≈4,000 mg L−1). The possibility of its treatment in an urban WWTP is studied measuring ammonia oxidation rate with non-acclimated sludge to the industrial effluent. Compost liquor appears as an ...

Combining primary collection with decentralised composting - a solution?
The environmental problems of urban areas extend over a wide range of spatial scales; i.e., the household, the place of work, the neighbourhood, the city, the wider region, and the world. In rapidly growing cities of the developing world, urban solid waste management (SWM) is currently regarded as one of the most immediate and serious problems faced by urban governments. Inadequate or unavailable ...

The effects of bioadditive in the form of yeasts and zeolite on the composting process and odour emission
The objectives of this paper are to determine the effectiveness of bioadditive in the form of yeasts and zeolite in reducing odour and ammonia emissions during composting and to assess its effects on the process. Two series of experiments were conducted. The higher dosage treatments reached thermophilic temperatures sooner and the high temperatures stayed longer. The application of bioadditive at ...

Compost stability: a comparative evaluation of respirometric techniques
The new Paradigm in waste management promotes attitudes and processes that conserve resources and reduce pollution. Under this philosophy, organic waste is increasingly recognised as a recyclable material, a useful resource, making composting one of the key elements of modern waste management. As the composting industry is expanding rapidly there is a growing need for a simple, fast, relatively ...

Influence of temperature during the initial phase of Composting on biological activity and emission of Ammonia and dinitrogen oxide
Composting is a robust and cheap biological treatment method useful for all solid biodegradable waste. The performance of composting can vary substantially depending on managing conditions such as oxygen supply and compost temperature. Oxygen and temperature affects the rate of degradation and may also influence emission of NH3 and N2O. The gaseous N losses during composting from organic ...

Compost based products: history, recent activities, chances
The amount of compost originating from source separated organic household waste collection in Germany is still increasing. At the end of the year 1997, app. 3.0 to 3.5 millions Mg fresh matter of non-mature and mature compost were produced in 515 composting plants with an input of respectively more than 1.000 Mg organic waste per year in Germany. According to Mellen (1998) an estimated 27% of the ...

Removal of 2-methylisoborneol from aqueous solution by cattle manure compost (CMC) derived activated carbons
The objective of this study is the synthesis of activated carbon derived from cattle manure compost (CMC) causing environmental problems using zinc chloride (ZnCl2) activation and to examine the suitability and performance of the prepared activated carbon (PAC) in removing 2-methylisoborneol (2-MIB) from aqueous solution. The influence of ZnCl2/CMC ratios and outgassing from the PACs on the ...

Bio-conversion of organic waste using composting technologies – a review
Composting is nowadays evolving as a highly technical process for processing organic waste separately replacing landfilling along with municipal solid waste. Vegetable waste with high organic content can be composted to produce nutrient rich material that can work as soil conditioner instead of dumping in open landfills. Various studies reveal that due to high organic content of vegetable waste ...

Composting: Art and science of organic waste conversion to a valuable soil resource
Raw organic materials such as grass clippings and manure are transformed into stable soil-like humic compounds through decomposition in the composting process. Composting is an age-old practice found in various settings, ranging from domestic to industrial. Compost maker machine is becoming an increasingly practical method of organic waste disposal when landfills reach capacity ...

Waste Management a Problem & Organic Waste Composters a Solution
What would it be like to wake up one day to a planet free of trash and other debris? You can know that this vision is a theory based on your present knowledge of the scenario. Because we’re still more concerned with increasing production than reducing or simply controlling the waste that results, we’ve created this situation. Try to imagine a world populated ...

Suitability of Wastes from Olive-Oil Industry for Initial Reclamation of a Pb/Zn Mine Tailing
An incubation experiment was conducted to evaluate the ameliorating role of two organic amendments—olive-mill solid wastes and compost from olive-mill solid wastes- in the ecological reclamation of a lead/Zn-mine tailing collected in southern Spain. Four enzymatic activities (dehydrogenase, β,-glucosidase, urease and phosphatase) and soluble and AB-DTPA extractable Pb and Zn and were ...

Introducing the technique of composting in a rural municipality in Chile
Waste management in Chile Until a few years ago there had been a lack in the supply of basic infrastructure needs like the supply of drinking water, sewage systems, electricity and communication in a lot of rural areas in Chile. With the advancing economic development further necessities have arisen. New objectives are the extended development of infrastructure, the conservation of natural ...

Effects of biowaste compost amendment on soil microbial biomass and specific carbon turnover in agricultural soils
The importance of biowaste compost as organic fertilisers has become more emergent in the last years due to the increased production of compost produced from biowaste. The utilisation of organic fertilisers in agriculture improves the physical, chemical and microbial properties of soils (Allievi et al., 1993; Senesi, 1989). Amendment of compost affects several soil properties positively like e.g. ...

Commercial composting provides food for thought
The retail sector and food manufacturers produce a mountain of waste but, unlike householders, they cannot simply throw it in the compost and wait for it to rot down. The Compost Association told edie about the obstacles in the way of recycling waste from the commercial sector. Compared to household domestic waste, biodegradable matter from the retail and catering sector represents only a small ...
