Production of Biogas from Agro Industrial Wastes

Introduction

 

The objective of the project work is to obtain large amount of methane in combination of agriculture waste such as sago, coffee pulp and poultry wastes in co-digestion with cow dung. The raw source is obtained from different places stored at different condition to obtain the maximum volume of methane from minimum raw material.

Achievements

 

The project report suggests that the biogas production was achieved by using organic solid wastes such as sago, coffee pulp and poultry wastes in co-digestion with cow dung. The feed optimization for biogas production was carried out by using RSM tool.

The coffee pulp waste was collected from the coffee seed processing industry in Yercaud hill station, Salem, Tamil Nadu, India. Cow dung was collected from a dairy farm. The samples were scraped off the feed lanes and collected in a bucket. The samples were transported immediately to our laboratory and placed in the digesters. The maximum gas production 28l/kg was achieved by the mixture of cow dung (150kg) with coffee pulp (25.5 kg), sago waste (25.5kg) and poultry waste (50kg) during the incubation period of 17.5 days. The biogas with methane was confirmed by using GC-MS analysis.
