Hide unhairing: Achieving lower pollution loads, decreased wastewater toxicity and solid waste reduction

This study aims to diminish the pollution being discharged into wastewaters through changes in the unhairing process. To this aim, we are replacing a reductive hair degrading process with a process which combines a reductive hair degrading process with an oxidative hair degrading process. Hydrogen p...
