“…Hence, the medium becomes more acidic, this acidification of the process has an adverse effect on the micro-organisms responsible for the breakdown of organic components. These findings agree with other research on anaerobic digestion (Jiang et al, 2012;Raynal et al, 1998). We can therefore infer that, if pH value falls significantly lower than the recommended pH value for anaerobic digestion, very little or no methane gas will be produced.…”

Open dumps and ill equipped landfills are some of the characteristics of solid waste management in Nigeria. This paper therefore seeks to investigate the viability of anaerobic digestion as part of an integrated waste management strategy for the city of Port Harcourt, Nigeria. In order to achieve this aim, the paper reviews literature on solid waste management in the study area. Alaboratory experiment was also conducted using organic solid wastefrom Port Harcourt.From the findings, it was revealed that anaerobic digestion could play a major role towards the attainment of sustainable solid waste management in Port Harcourt. The small laboratory sample of 10 grams used for the experiment produced about 0.796 litres of methane gas, means that 1 tonne of organic waste in Port Harcourt will generate about 79600 litres of methane gas with energy equivalent of about 1592000_kj.The paper concluded that in a city like Port Harcourt where several tonnes of solid wastes are produced every day, a substantial amount of methane gas could be recovered for electricity generation. It was therefore recommended that anaerobic digestion should be used in order to boost the electricity capacity of the city whilst also improving the quality of life of the people.

“…Throughout the last years the two-staged AD has been applied to treat a wide variety of substrates, ranging from liquid model substances like glucose over highly complex industrial wastewaters and animal products to solid organic waste or purposefully grown energy crops (Ghosh et al, 1985;Verrier et al, 1987;Raynal et al, 1998;Ince, 1998;Yu et al, 2002;Demirer and Chen, 2005;Zielonka et al, 2010;Lindner et al, 2016). The reactor conguration employed is tailored to the primary substrates of the system.…”

“…Bouallagui et al [11] used ASBR as the methanogenic bioreactor in two phase digestion (of fruit and vegetable wastes) which resulted in significant biogas productivity and better effluent quality with a 96 % reduced chemical oxygen demand. Two stage anaerobic digestion was used by Raynal et al [74] for vegetable waste (potato peeling wastes, salad leaves, and cannery waste of green peas and carrots mixture) using multiple liquefaction reactors and a central methane reactor. Rajeshwari et al [73] explored USAB digester for the sequential two stage digestion of vegetable wastes.…”

Vegetable wastes occur throughout the supply chain and vary widely depending on its processing. Globally, more than 30 % of the loss occurs at the retail and consumer levels, of which the post-harvest and processing level wastages account for the major share. The wastes so generated pose an environmental threat and call for the development of a pollution-free model. Studies on the characterization of unutilized, rotten, and discarded fractions of the vegetable wastes indicate their potential candidature for reprocessing. Generation of renewable energy by bioconversion of vegetable wastes is gaining importance as it has proved to be a proficient means of utilizing the perishable vegetable residues. Researchers and industries are now fully engaged in a number of projects involving the technology of ''waste to fuel'' with a view to overcome the disposal problems. The present article deals with the studies conducted on vegetable wastes for production of various types of biofuel.
