Statement of the Problem
: Poultry industry produces worldwide around 80,000,000 ton of chicken meat per year. Since feathers
represent about 7-10% of the meat production, a huge amount of such waste is generated annually. Nowadays, the treatment of this
left-over 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 valorize this waste is important to reduce the environmental impacts, increase
the efficiency of using natural resources, and provide economic benefits. Our project has tackled different routes for reusing chicken
feathers wastes with the aim of obtaining materials with industrial application and involving environmental benefits. The proposed
solutions include the manufacture and characterization of two types of materials using or incorporating chicken feather waste in the
process formulations for different final applications. Thermoplastic biocomposites including feathers could be used for manufacturing
structural elements while non-woven materials could find an application niche either as bio-sorbent or as insulating barriers.
Methodology &Theoretical Orientation
: Chicken feathers were stabilized by an oxidative cleaning with aqueous hydrogen peroxide
and processed as filler in composite materials by using a Brabender mixer. Alternatively, the cleansed feathers were treated in a
Shirley analyzer machine to remove the central quill and the resulting fibers were mixed with wool long fibers (50/50 %wt) in a card
machine to obtain a non-woven material. Regarding the characterization of samples, on the one hand, tensile tests were carried out to
determine mechanical properties of composites and, on the other hand, the biosorption of heavy metals and the acoustic absorption
coefficient were determined.
Finding
: It was possible to include up to 30% v/v of the residue in the composite and some formulations yield composites with
enhanced properties. Moreover, the non-woven proved an efficient retention of metal ions such Cu
2+
.
Conclusion & Significance
: Research shows that the strategies used reduce the consumption of raw materials by incorporating the
properly treated waste.
Biography
Macanás J is an Associate Professor in the Department of Chemical Engineering at Universitat Politècnica de Catalunya. His present research is mainly focused
on Materials Science and Nanotechnology. He has developed some metal-polymer nanocomposites with different configurations for environmental and catalytic
applications. He is currently working on the valorization of several industrial residues as materials with approaches such as the reported here.
