Production of methane from poultry manure

Poultry industry is a fast growth industry globally in line with high demand in the Halal meat at Islamic countries especially in Malaysia.Increasing number in broiler production creates a lot of environment issues.The recent stunning issue that attracts the attention of the public is about 400 tons...
