biogas HANDBOOK 4 Main applications of biogas The production of biogas from AD is widely used by modern society for the treatment of livestock manure and slurries. The aim is to produce renewable energy and to improve their fertiliser quality. In countries with significant agricultural production, the strengthening of environmental legislation and regulation of manure and vegetable wastes recycling increased the interest for AD as a cheap and environmental friendly solution. Latest developments in Europe, USA and other parts of the world have shown increasing interest among farmers to cultivate energy crops, used as feedstock for biogas production. AD is today standard technology for stabilisation of primary and secondary sewage sludge, for treatment of organic industrial waste from food-processing and fermentation industries as well as for the treatment of the organic fraction of municipal solid waste. A special application is biogas recovery from existing landfills. 4.1 Agriculturalbiogasplants The agricultural biogas plants are considered those plants which are processing feedstock of agricultural origin. The most common feedstock types for this kind of plants are animal manure and slurries, vegetable residues and vegetable by products, dedicated energy crops (DEC), but also various residues from food and fishing industries etc. Animal manure and slurries, from cattle and pig production, are the basic feedstock for most agricultural biogas plants in Europe, although the number of plants running on DEC was increasing the last years. AD of animal manure and slurries is considered to improve their fertiliser value for the reasons listed below: • Manure and slurries from different animals (cattle, pig, poultry etc.) are mixed and co- digested, providing a more balanced content of nutrients • AD breaks down complex organic material such as organic nitrogen compounds, increasing the amount of plant-available nutrients • Co-digestion of manure with other substrates adds various amounts of nutrients to the feedstock mixture. The design and technology of biogas plants differ from country to country, depending on climatic conditions and national frameworks (legislation and energy policies), energy availability and affordability. Based on their relative size, function and location, agricultural AD plants can be classified as: - Familyscalebiogasplants(verysmallscale) - Farmscalebiogasplants(smallormediumtolargescale) - Centralised/jointco-digestionplants(mediumtolargescale) 4.1.1 Familyscalebiogasplants In countries like Nepal, China or India operate millions of family scale biogas plants, utilising very simple technologies. The AD feedstock used in these biogas plants originate 30PDF Image | biogas HANDBOOK
