Solid organic wastes create potential risks to environmental pollution and human health due to the uncontrolled discharge of huge quantities of hazardous wastes from numerous sources. Now-a-days, anaerobic digestion (AD) is considered as a verified and effective alternative compared to other techniques for treating solid organic waste. The paper reviewed the biological process and parameters involved in the AD along with the factors could enhance the AD process. Hydrolysis is considered as a rate-limiting phase in the complex AD process. The performance and stability of AD process is highly influenced by various operating parameters like temperature, pH, carbon and nitrogen ratio, retention time, and organic loading rate. Different pre-treatment (e.g. mechanical, chemical and biological) could enhance the AD process and the biogas yield. Co-digestion can also be used to provide suitable nutrient balance inside the digester. Challenges of the anaerobic digestion for biogas production are also discussed.

The production of biogas from livestock waste manure in particular is one of the alternative utilization of organic wastes that can be implemented in Indonesia since there is a huge potential of bio-energy in Indonesia. This study utilizes cow manure as the raw material for making biogas and it is coupled with a cow rumen fluid and water. The objective of this study is to determine the effect of manure, rumen, and water composition in biogas production. The research was conducted in anaerobic for 60 days. The composition of manure, water, and the rumen were vary following the variable and ratio; variable A (manure and water); variable B (manure and rumen). The results indicate that the variable A (manure and water) with a 1:3 ratio, and the variable B (manure and rumen) with a 1:2 ratio produced the highest volume of biogas compared to other ratios. The highest biogas production occurred on average at day 23.

Agriculture Residue

To achieve energy security and to address energy related environmental issues attempts have been made to find out such energy resources that are economically viable and environmentally friendly. Biogas appears as a sustainable, renewable and carbon neutral energy source, a substitute to reduce the global fossil fuels dependency. Agricultural activities generate huge amounts of organic residues annually worldwide. Microbial conversion of agriculture residue and organic wastes to produce biogas offers an attractive way for energy supply, resource recovery and waste treatment. Energy generated is renewable can have positive impact on environment, replacing fossil fuels and mitigating greenhouse gases emissions. In addition to a clean and cost effective energy source, it improves the management of manure and organic wastes and replaces inorganic fertilizer. Biogas production in the agricultural sector is a fast growing market particularly in many European countries. This article is aimed to review and investigate the potential contribution of biogas from agricultural residues. Techniques for quantitative assessment of the residue from different crops that can be recovered sustainably as a potential resource for biogas production are discussed.
