Low cost Biodigesters to produce biogas and natural fertilizer from organic waste
Results

Biodigesters offer a effective way of treating organic waste, also generating biogas and biol.Biodigesters can therefore help mitigate pollution through good waste management; they produce fuel and thus prevent deforestation; they produce natural fertilizer and avoid the use of chemicals, increasing productivity and reducing the expansion of farmland.

Quality of life in communities is improved, primarily in terms of the health of women and children, since meals can be cooked without smoke.The production and use of natural fertilizer gives added value to products, which can be marked as biological, and increases agricultural production by between 30 and 50%, thus boosting family income.Biol may also be sold by farmers as organic fertilizer, generating other income.To market biol and apply it on crops, it has to be stable and free of any pathogens.For this reason biodigesters can, where necessary, be integrated into constructed wetlands for the treatment of biol, thus mitigating pollution and offering an effective method of wastewater treatment and reuse.

Low-cost biodigesters are an effective technology for waste treatment.Alternatives include septic tanks or seepage pits.These solutions, however, require maintenance, which is not easy in rural areas, and are only used to clean up waste, missing the opportunity to generate other usable products.Composting, which is another valid approach because it generates a valuable product such as compost, requires increased workload and space.Furthermore, composting does not produce fuel.For all these considerations, where there is enough water for the mix, the right organic matter, and with proper training and understanding, the biodigester is a very interesting alternative offering multiple benefits.
