Poultry industry produce worldwide around 80.000.000 ton per year of chicken meat. Consequently, chicken feather wastes are generated representing between 7-10% of the meat production. Nowdays, the treatment of this waste is associated to high environmental and economic impacts since chicken feathers are a truly waste that requires management and treatment (incineration, compost, etc.) which have a high cost compared with the near zero value of the feathers. For this reason, the proposal of commercial alternatives to valorizate this waste is important with the consequent environmental (more efficient use of natural resources by reusing waste) and economic (value added to a product that is needed would reduce the price of processed chicken meat) benefits that these solutions could provide. This project proposes different routes for reusing chicken feathers wastes with the aim of obtaining materials with industrial application and involving enviromental benefits. The proposed solutions include the manufacture and characterization of three types of materials using or incorporating chicken feather waste in the process formulations: thermoplastic composites for structural elements, flexible polyurethane foams for furniture and non-wovens for the development of biosorbent and insulating barriers. It is expected that the technological development of this materials promotes the sustainable use of these wastes taking into acount that chicken feathers are an ubiquitous renewable waste material characterized by their abundance and low cost and low density and several reactive functional groups (carboxyl and amino groups) that allow interaction with plentiful of chemicals. Hence, the expected scientific and technical contributions of the project will stablish the methods to fabricate and develop these 3 types of materials, including research of: i) fabrication of the thermoplastic composites, flexible polyurethane foams and non-woven barriers i) the characterization of the properties of the aforementioned materials, iii) the environmental benefits of using this new type of biosorbents barriers due to the improved resource efficiency combined with waste reduction, which all together implies the assesment of the environmental impacts of the proposed solution, which will be addressed by using Life Cycle Assessment methodology (LCA).
