Biogas plants are decentralized energy system that can lead to self-sufficiency in heat and power requirements, and at the same time reduces environmental pollution. A biogas plant stabilizes organic waste through natural biological process in the absence of air and transforms waste into biogas and biofertilizer. Such facilities are well-suited to wet organic material and are commonly used for treating biodegradable waste materials such as waste paper, grass clippings, leftover food, sewage and animal waste. The components of a modern biogas plant includes manure collection, anaerobic digester, effluent treatment plant, gas storage, and CHP or electricity generating equipment.

Thermophilic composting of organic waste is getting increasing attention worldwide because of its ability to convert solid wastes into organic fertilizer within a short period of time. The system consists of an enclosed reactor laced with a microbe-enzyme cocktail. The commonly used microorganisms are naturally occurring bacillus sp., pseudomonas sp, bifidobacterium sp., lactobacillus sp., streptomyces sp., corynbacterium sp etc. Enzymes such as proteinase, keratinase, lipase and cellulose are employed to accelerate the aerobic digestion process. Salient Features The most important feature of thermophilic composting process is its operating temperature range of 70 – 80 °C which eliminates all pathogens and harmful … Continue reading →
