  • 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 ...

  • 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 ...

  • Effects of biowaste compost on vegetative growth, Yield and fruit quality of james grieve apples

    In Lower Austria 69 agricultural composting plants are in operation in addition to municipal and commercial composting plants. The agricultural composting plants process separately collected organic household waste as contractual partners for the neighbouring municipalities. The compost produced is used to a large extent on the agricultural fields of the plants' owners. In order to improve the ...

  • Deregulation and voluntary self-regulation of producers of compost and secondary raw-material fertilizers -against the background of the biowaste and fertilizer ordinances

    Since the RAL (Institute for quality assurance and labelling) introduced the quality mark for compost in 1992, more than 300 German composting plants have decided to adopt this voluntary quality control system. This system has significantly helped to define characteristics of high-quality, marketable composts. The quality standards agreed upon with the end-user are guaranteed and monitored within ...

  • 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 ...

  • Experience in improving fertiliser value of compost by enriching with urine

    Urine contains a lot of nitrogen, phosphorus and potassium, and could act as valuable plant fertiliser. But urine is often either flushed down a toilet or enters a pit latrine, thus being lost to agriculture and increasing surface and groundwater contamination with nitrogen. Ecological sanitation concepts are closing the loop of nutrients contained in wastewater with agriculture. Besides ...

  • Technical and financial evaluation of composting programs in Asia

    Because the solid wastes of Asian cities are typically comprised of 70-85% organics, dirt and dust (Furedy, 1989b), composting has long been considered an interesting option to reduce the amounts of waste to be transported and disposed of in landfills. Furthermore, composting makes use of natural resources (i.e., the organic materials in wastes) that would otherwise be wasted. However, composting ...

  • Odour emissions from MSW composting process steps

    This study brought to the definition and the calculation of Odour Emission Factors (OEFs), which enable the estimation of odour emissions from a composting plant by relating the quantity of odour emitted to the atmosphere to a given associated activity. The results show that the aerobic biological treatment has the highest odour impact, with an OEF of 1.4 ? 108 ouE t−1. Moreover, the efficiency ...

  • Principles for market-orientated production of compost products from the perspective of a plant operator

    The treatment of biological waste, and composting in particular, has received a great boost in recent years since the introduction of source separation for biological waste in the 1980s. At the same time, legal regulations and guidelines for the construction of composting plants, production and trading of compost products were expanded. At present, about 6.5 million tonnes of biological waste is ...

  • 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 scale. The electronic nose consists of an array of electronic chemical sensors with partial specificity and an appropriate pattern recognition system ...

  • 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 ...

  • How many days does it take to ferment organic fertilizer

    Most domestic organic fertilizer products can only be composted and fermented for 7-10 days, and such products can only reach the harmless standard. The fermentation process of high quality organic compost usually takes 45-60 days. This is because in the early stage of heating and high temperature of the organic ...

  • Priming of prosopis cineraria (L.) druce and acacia tortilis (forssk) seeds with fulvic acid extracted from compost to improve germination and seedlin

    Composting of waste plant materials and its use in agriculture and landscape sites is an environmental friendly way of reducing waste material and conserving the environment. In this perspectives a survey has been performed at the Dubai based International Center for Biosaline Agriculture to compost the plants based waste material (lawn cuttings-grass) to compost. The material was inoculated with ...

  • Investigations into the possibility to compost paraffincoated packaging materials

    Utilisation of biodegradable materials is indispensable for effective economic operation (Soyez, 1998). However, the requirements to be met by the application characteristics sometimes prevent use of such materials. For example, packaging materials for foodstuffs, where protection of the contents is the predominant aim, are required to display hydrophobic properties. Paraffin-coated papers have ...

  • GTMA Mission: The Netherlands

    “I’m looking for a partner in Canada,” says Ward Janssens from Orgaworld, a composting and biocel fermentation plant we visited. Chris Kallio, with the town of Newmarket, says, “It wasn’t until this reception that I realized how strong the Dutch interest in making North American connections is.” “They want to use Canada as a gateway to that market,” says Kallio. And if it benefits us, why not let ...
