Biogas to Bio-CNG from paddy straw: A review

Abstract

Quick industrialization and growing the urbanization besides automatic undeveloped give achieve up to a lofty call of energy in every one of forms such as thermal, electrical and mechanical. To minimum acceleration energy is accomplished by burning of fossils fuels like coal; lubricate which further leads to its overexploitation in unsustainable conduct. The overuse of fossils fuels has increased environmental turbulence leading to serious detrimental effects such as large scale climate changes and global warming. This further leads to a shortage of any permanent source and thereby increasing the imports of the fuels. But we are so expedient to have some sustainable and ecological forms of energy for example- biomass, solar and, etc. Due to its everlasting characteristics and availability make it a better alternative for the present and future. Due to increasing environmental pollution, the researches emphasized supplementary on the making of biogas and bio-CNG from paddy straw. Producing renewable energy from paddy straw helps to lessen the energy catastrophe and paddy straw management, which is completed by anaerobic digestion. The future lies in the conversion of paddy straw into biogas. Keeping efficient management and conversion of paddy straw in mind Biogas or Bio-CNG production is the best possible method to obtain the clean low-carbon output. Biogas or bio-CNG obtained by anaerobic absorption of paddy straw tin be old as an energy cause for a choice of application namely, heating, cooling, brake cooling, electricity age bracket and gaseous fuel for vehicular applications. Paddy straw has immense economic value in the form of fresh gas production. This paper focuses on the review of exploring the most promising alternatives of paddy straw management and transmutation of biogas to bio-CNG to mitigate environmental pollution.
