Agricultural Use of Different Residual Waste Composts - Current Situation and Experiences in France
ABSTRACT Quality standards have been recently established in France for sewage sludge composts and other urban composts (greenwaste, biowaste and municipal solid waste composts). These standards allow to guarantee the innocuousness of the composts. ...

Evaluating the potential of an electronic nose for detecting the onset of anaerobic conditions during composting
Most bad odours in composting plants are formed under anaerobic conditions and often they could be avoided if detected early enough. In this project an electronic nose was used to evaluate the odours produced during a composting process at bench ...

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 ...

Low-cost composting of fruit processing wastes in Hungary
Aim of the project The research described in this paper was undertaken in order to assess the economic and environmental viability of composting fruit juice wastes from the RAUCH Hungaria Kft. fruit processing plant in Budapest, Hungary. Hungary ...
-
Composting of municipal waste in Poland
Composting constitute an important element of the integrated systems of municipal waste management, which is being developed these days. In such systems, the process is employed mainly in the treatment of selectively collected biologically ...

Composting in flanders: the vlaco experience
In Belgium, waste policy mainly belongs to the responsibility of the regional authorities. Therefore, apart from some European regulations, Flanders, Wallonia and Brussels have their own laws, rules and strategies with respect to waste management. ...

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. ...

The control of the process and compost quality
The European Commission has adopted a new proposal on landfill whose objective it is to reduce the impact of waste disposal on the environment. The new directive introduces a series of new elements and provides for a number of safeguards with ...

Hybrid composting systems: appropriate technology for Austral-Asia?
Composting is a strongly emerging option in waste management in Austral-asia. It has been widely acknowledged that a successful integrated waste management strategy must adequately address the organic waste stream. Composting is the most economical, ...

Composting of municipal green waste using a hybrid Mode of the aerated static pile
The aerated static pile (ASP) system developed in Rutgers University (Finstein et al., 1980) is based on a deep understanding of composting as a microbial process. It allows for a good degree of process control and high organic matter stabilisation ...

The relevance of moisture control in organic municipal Solid waste windrow composting process
The valorisation of the Municipal Solid Waste composting fraction assumes importance in management strategies of the MSW and constitutes a way of producing an organic material such as humus to improve the soil aeration, the water holding capacity ...
-
Determination of the relative and absolute humidity in Compost piles by differential pectroscopy using Tuneable diode lasers
The composting of biological waste is an important step towards the establishment of closed cycles of matter. A constantly high quality of the compost is, however, of utmost importance for the deliberate re-introduction of compost into the ...

Effect of different forced aeration methods on Vertical temperature distribution and reaction rates During composting
The application of forced aeration, namely in the upflow (blowing) or downflow (suction) mode has been increasing in modern composting processes. These aeration modes often create a sharp temperature gradient in the composting mass. Examples of ...

Microbial biomass c and ninhydrin-reactive n as Parameters to characterize composting process
The use of compost in agriculture is increasing as a source of organic matter to counteract the decrease of organic matter level in soils and as a means of disposal of agricultural and domestic waste. Despite many researches on the subject, there is ...

Reduction of ammonia emissions during composting by Uncoupling of oxygen demand and heat removal
Intensive pig production systems result in high emissions of ammonia, odour and greenhouse-gases (methane and laughing gas) by exhaust ventilation air. Moreover, large amounts of manure (faeces and urine) are produced with insufficient nearby land ...

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 ...

Regulation of nitrogen contents of Composts during composting first experimental results
More than 3 Mio. Mg of compost were produced in Germany in 1998 (Wiemer and Kern 1998). Kitchen and garden waste from households as well as waste from landscaping and parks were used as substrates to a high extent. The composts were mainly used in ...
