Grant project deliverable

Valorisation of waste chicken feathers

Grant holder: Dr B Sithole

Institution: CSIR

Grant: CSIR/IU/WRIU/2016/004

Duration: 1 April 2016 to 31 March 2019

Status: Complete

Project outline: The poultry-processing industry generates large quantities of feather by-products. The feathers are considered wastes although small amounts are into valuable products such as feather meal and fertilizers. The remaining waste is disposed of by incineration or by burial in controlled landfills. A closer look at the structure and composition of feathers shows that a chicken feather (quill and fibre) can be used as a source for pure structural protein, keratin, which can be exploited for conversion into a number of high-value bio products. Additionally, a number of technologies can be used to convert other biological components of feathers into high value added products.
