Biodegradation of Keratin-Rich Husbandry Waste as a Path to Sustainable Agriculture

Every year, the size of human population grows; with it, need for agricultural products increases. This leads to an increment in volume waste, including hard-to-degrade keratin-rich ones, such as feathers. Currently, most agro-industrial complex protein by-products are utilized by incineration, landfilling, and chemical hydrolysis. Such methods do not meet modern trends development a sustainable economy, negatively affecting environment humans, preventing reusing waste. An alternative is biodegradation, which consists application living organisms their enzymes recycle by-products. approach only sustainable, but also makes it possible obtain waste hydrolysis that demand manufacture fertilizers feed additives. brings agriculture closer circular economy recycling process more profitable. review article emphasizes significance keratinolytic microorganisms keratinases improvement green processing complex, necessary economic development.
