In India, chicken farms supply chicken to small shops called "Chicken Stalls" where they are usually slaughtered and cut. Indians usually ask for skinless chicken when ordering from these shops. Therefore, the skin is disposed of from these shops. This skin is disposed usually in the public drain and therefore becomes potentially hazardous solid waste in the environment. After seeing the excess of chicken skin/fat in the market, we realized that this waste could be used to create biodiesel. This biodiesel could be used to power automobiles (with modified engines), for domestic purposes and biodiesel could also be a cheaper source of fuel compared to refinery diesel. Fat from the waste chicken skins (sourced from local shops), was first extracted but the viscosity of these animal fat based oil is higher, so these can be brought down by a process known as "Transesterification" which is the process of exchanging the organic group R″ of an ester with the organic group R′ of an alcohol. These reactions are often catalyzed by the addition of an acid or base catalyst. An experimental work has been carried out to analyze the emission and performance characteristics of a single cylinder compression ignition engine fueled with mineral diesel and diesel-biodiesel blends. The results of experimental investigation with biodiesel blends were compared with that of baseline diesel.
