Study on Plant Growth Promoter from Proteineous Wastes from Leather Industry

Tanneries generate huge quantities of solid wastes as fleshings. If these bio-waste materials are not utilized properly they are potential source of pollution. So in the present study it has been tried to convert these hide fleshings into NPK fertilizer. During the process of manufacture of NPK fertilizer, phosphorous and potassium were incorporated by suitable chemical reaction under desired conditions of temperature and pressure. The resultant liquid product was converted into pellet form and field tested on horticulture plants (Balsam Plant - Impatiens balsamina).
