Pretreatment Methods of Organic Wastes for Biogas Production

Pretreatment Methods of Organic Wastes for Biogas Production

During biogas production, the rate-determining step for the conversion of complex organic matter is the hydrolysis. Different pretreatment methods aid in facilitating the anaerobic digestion by increasing the rate of organic matter hydrolysis. This in effect results in enhanced production of biogas and aids in waste stabilization as well as disposal. This review gives an overview of the methods...

Anaerobic Digestion of Kitchen Wastes: “Biogas Production and Pretreatment of Wastes, A Review”

Currently, much of our biodegradable wastes such as kitchen wastes, agricultural wastes & animal wastes are used to produce Biogas, a powerful greenhouse gas. Anaerobic digestion (AD) is a treatment that composts these wastes in the absence of oxygen, producing a biogas that can be used to generate Heat & Power. Producing renewable energy from our biodegradable wastes helps to tackle the energy...

Pretreatment of feedstock for enhanced biogas production

Physico-chemical pretreatment and fungal biotreatment for park wastes and cattle dung for biogas production.

With the rising demand for renewable energy and environmental protection, anaerobic digestion of biogas technology has attracted considerable attention within the scientific community. The effect of physico-chemical pretreatment on cellulose degradation followed by fungal treatment by Aspergillus terreus and Trichoderma viride to treat cellulosic biomass for enhancing its digestibility was inve...

A review of biogas production methods from wastes and sewage and the explanation of its process

Thousands of tons of urban solid waste and human and animal waste in cities and villages of Iran have endangered the health of the environment and increased the greenhouse gases. On the other hand, the increasing trend of energy consumption has caused energy crisis phenomena in the world. Moreover, the increasing consumption of energy from fossil fuels has caused emissions from these fuels. Hen...
