snvworld.org – 
The purpose of this Institute for Sustainable Development (ISD) pilot project is to encourage the use of homestead biogas technology in Tentulia district, Bangladesh. The ISD provided the possibility to acquire a homestead biogas plant without any cash down-payment and to use cow dung and bioslurry as a reimbursement mechanism. The study also sheds new light on the broader motivations for acquiring biogas plants; in particular regarding the barriers to acquiring biogas plants and indicators to better determine potential biogas plant owners.

Abstract: Methane was generated from cotton waste, while considering its pollution in textile industries. Cotton waste in-cludes solid content and is rich in cellulose having a moisture content of 8.8%. It is difficult to form slurry as the waste float on water and hence an experimental set up has been made like a batch type digester and experiments were conducted with a different proposition of water with or without addition of seeding materials. It was found that cotton waste with 5 to 7.5% seeding material like cow dung or pig dung at temperatures of 30 to 350C generated bio gas continuously, with a reasonably high yield from the tenth day after feeding. The gas contained rich methane and was tested in a single cylinder diesel engine as a dual fuel had the tendency to save 60% of diesel.

Summary
The report presents the finding of the Initial Environment Examination (IEE) conducted for the Pakistan Domestic Biogas Program, proposed to be implemented by the Rural Support Program Network (RSPN), Pakistan. The program envisions setting up 300,000 domestic biogas plants across Pakistan within 10 years of time.

Potential impacts likely to arise from the construction and subsequent operation of the domestic biogas digester units on physical and socio economic and environment was assessed and the mitigation measured identified to reduce the possible impact likely to cause its operation. An Environmental checklist has also been developed to implement the recommendation of IEE.

On the basis of the assessment, the report concludes that since Pakistan is an energy deficient country, whose major supply is imported, there is an urgent need to provide an alternative source of energy and the proposed domestic biogas program seems to help fulfil this objective without resulting in any potential environmental impact. No adverse effect on the environment was identified because of this program.

Detailed findings and conclusions can be found in the report along with the adopted IEE methodology, identified potential impacts and the mitigation measures and the environmental checklist developed to overcome the impacts.
