- 15. Ctd. • Animal Waste ▫ Cattle waste is converted into biogas, to be used as a fuel for cooking ▫ Slurry produced after extraction of gas is utilized as a natural fertilizer in organic farming ▫ Cow dung is also used to prepare useful items like bathing soaps, bathing powder,dhoop sticks etc. based on ayurvedic formulae

Editor's Notes
- Advantages: By such an integrated development approach, practically all of the waste produced in the eco village is recycled or reused. By thus maximizing the recovery of resources from the recyclable and biodegradable waste one can reduce the burden on landfills and other waste management systems
- GEV was recently listed among the top 100 agricultural innovators for effective usage of PRBs.
- By using this simple technique one can avoid the labor intensive task of removing weeds or usage of any chemical weedicides
