Bio Gas - Using Organic Waste


Every industrial house or a large colony generates considerable amount of organic waste - both as human excreta and as food and vegtable waste.

With sticter and stricter implementation of pollution control laws, sewage treatment plants have become the norm. Every small town starts clamouring for the centralised sewage system - Many western coountries and a few factories in chennai boast of expensive sewage treatment for RECOVERY of water and make hugh claims about the quality of the recovered water.

What no one is talking about is the cost, and the amount of methane which goes into the atmosphere, un used.

When one understands the fact that 1 ton of methane is considered equivalant of 20m tons of Carbon-di-oxide for the purpose of carbon credit, one knows the enormity of the methane's negative impact on environment.

One ton of dry organics can generate 200 to 300 cubic meters of bio gas, which can replace a 6 to 10 LPG cylinders and also provide excellent fertiliser for the plants, the value of the organic waste can be undersood.

Thus, recovery of the biogas from the organics of the clony or a factory

    - saves the energy used for STP
    - avoids the attendant negative aspects of treating sewage
    - Provides energy source and saves money
    - prevents global warming by both replacing conventional fuel and reducing methane
        (the fetisation effect of the residue can be considered to fix the amount of co2 generated while burning the biogas)

Thus, Biogas generation has multiple advantae and has a pay back not comparable - especially if considered as an alternate to sewage treatment.

SECO offers to design and supervise the implementation of such plants as a part of its commitment to work against environment pollution caused by ineffective sewage treamant plants, and as apart of its effort against global warming.
