  • Introduction of composted digestates in agriculture

    Municipal organic waste is increasingly recycled by aerobic composting or anaerobic digestion procedures. In 1997, 230 000 Mg organic waste were composted and used for agriculture in the region of Cologne, which is an increase by 70% compared to 1994 (Anonymous, 1999). Therefore, the effects of compost on the soil and the plants require studies on:- its nutrient contents to contribute to the ...

  • In-Vessel Composting of Residential Organics

    In 1994, the Regional Municipality of Peel began work on a system for residential organic residuals collection and composting. Although Peel had been promoting backyard composting, greater diversion rates were sought. The public was surveyed to determine what level of cooperation could be expected for source separation and setting out of food, soiled paper products, yard trimmings, etc. “We knew ...

  • Use of Fat, Oil and Grease Waste as an Agricultural Soil Conditioner

    Wastewater from the food processing and food service industries can contain large quantities of fat, oil and grease (FOG). Most North American jurisdictions have bylaws limiting the concentration of oil and grease in sewer discharges. As municipal source control efforts become more aggressive, quantities of FOG waste requiring proper treatment/disposal will increase. At the same time access to ...


  • 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. Other standards have been defined in order to predict the compost effects on soil properties: the index of biological stability (ISB), based on ...

  • Different methods to derive pure silica from agriculture waste

    Rice residues are important natural resources, the management of these residues is a major challenge for environment protection. The use of different techniques to produce silica with minimal mineral contaminants having high Specific Surface Area (SSA) has been investigated. The different methods used depended on treatment of rice hulls with different dilute organic acids and hydrochloric acid, ...

  • The CAMBI process and agriculture, a sustainable solution?

    Abstract Both public acceptance and interest from farmers for spreading biosolids from waste water treatment plants (wwpt) on arable land, are dependent on some fundamental criteria. These criteria are, however, quite straightforward. The biosolids should be safe, easy to handle, a well documented source of plant nutrition, without disagreeable odours and easily available. A big part of the ...

  • The emergence of urban agriculture: Sydney, Australia

    Across the world the phenomenon of urban agriculture (UA) is defining itself after emerging from a mainly grass-roots response, evidenced in the Sydney Metropolitan Region by the Hawkesbury Harvest phenomenon and the Sydney Food Fairness Alliance, to powerful global forces which are negatively and paradoxically impacting on the quality of life of urban and farming communities. In the developed ...

  • Application of rural slaughterhouse waste as an organic fertilizer for pot cultivation of solanaceous vegetables in India

    Background:The lack of electricity and water supply in rural abattoirs in developing nations prevents the adoption of waste-processing technologies practiced in economically advanced countries. This research attempts to recycle waste blood and rumen digesta generated in rural slaughterhouses as organic fertilizer, thus promoting sustainable agriculture. Results:The values of 5-day biochemical ...

  • Value of composted organic wastes as an alternative to synthetic fertilizers for soil quality improvement and increased yield

    One of the major problems with agricultural soils in the tropical region of the western Pacific islands is their low organic matter content, which results from rapid decomposition due to the hot and humid environment. Composted organic material is frequently applied on agricultural fields as an amendment to provide nutrients and also to increase the organic matter content and to improve the ...
