Organic compounds decompose under anaerobic condition to yield biogas. This work presents results of the study on biogas production from fruits and vegetables waste materials and their effect on plants when used as fertilizer (Using digested and undigested sludge). It has been observed that the highest weekly individual production rate is recorded for the cow dung (control) slurry with average production of 1554 cm 3 , followed by pineapple waste which had 965 cm 3 of biogas, then by orange waste which had 612cm 3 of biogas, lastly, pumpkin and spinach wastes had 373 cm 3 and 269 cm 3 respectively. The results obtained shows that difference in the production of biogas to a large extent depends on the nature of the substrate. All the substrates used appeared to be good materials for biogas production and their spent slurries can be used as a source of plant nutrients.

    • "If it is removed from biogas before burning, then chicken manure would be a good input in digesters for biogas production at room temperature as well as mesophilic temperature. Also the mixture of cow dung and pig dung produces high rate of biogas production.Sagagi B.S et al [18] investigated that the biogas production rate is high in the case of cow dung slurry followed by pineapple waste, then by orange waste, pumpkin and spinach wastes. The difference in biogas production to a large extent depends on the nature of substrate.M.O.L. Yusuf et al [19] carried out a work on assessment of biogas production from horse and cow dung. "

    ABSTRACT: This Investigation mainly consists of design and development of biogas digester for improving the bio gas production rate and methane content using cow dung, silkworm larval litter and cattle urine. Efficient portable anaerobic digester is designed and developed using fiber reinforced plastic composite material which can withstand the temperature up to 800. The capacity of bio digester is about 50kg of feed stock material with 0.75m3 gas collector. In this investigation Biogas has been generated using cow dung, silk worm larval litter and cattle urine. Bio gas production rate calorific value was increased by 33% and 8.3% respectively when the cow dung, silk warm larval litter and cattle urine is mixed in the ratio of 3:2:1.

    • "Basically, biogas is low grade natural gas that contains 50-65% methane (House, 2007). Furthermore, biogas is a flammable gas that is produced by using anaerobic (oxygen free) digestion which is a biological treatment process to cut odor, generate energy and enhance the storage and handling characteristics of manure (Sagagi et al., 2009). Anaerobic digestion is considered as a good method of removing the high concentration organic waste (Kim et al., 2006). "

    ABSTRACT: Anaerobic co-digestion of swine manure and corn stover for biogas production has been studied in two completely-mixed and semi-continuously fed reactors (Reactor 1 and Reactor 2). Each reactor had a working volume of 14 liters and was operated at 35°C, a hydraulic retention time of 25 days, and an agitation speed of 120 rpm. Initially the reactors were operated as duplicates and each was fed with 560 ml of swine wastewater per day. After a stable performance had been achieved in both reactors with almost the same results, corn stover was added to Reactor 2 to get a Carbon to Nitrogen ratio (C:N) of 10:1. Since then 560 ml of swine wastewater and 14 g of corn stover have been added to Reactor 2 every day to keep the C:N ratio at 10:1. In the meantime Reactor 1 has been fed the same as previously.
