Develope biological materials from waste in the process of beer residue

Update: 10/9/2014

Researchers from the UPM and CSIC has developed biological materials from waste in the process of brewing for bone regeneration.

According to a study from the Center for Biological Materials Technology Politécnica de Madrid University (UPM), Institute for Materials Research, chemical catalyst and oil belonging to a large research center of the Spanish Consejo Superior de Investigaciones Cientificas (CSIC), in cooperation with Mahou and Createch company, has developed materials that are biocompatible. This material is used as aids bone regeneration waste from the food industry, largely from the residue (remainder) after the brewing process. The new material can be considered as a replacement prostheses made ​​from sheep bone or synthetic material expensive, harmful to the environment.

Waste from the brewing process containing the main chemical components found in bone, such as phosphorus, calcium, magnesium and silica. After going through the process of change, this waste can be used as tools to support or frame shaped to promote bone regeneration in medical applications by the way, rinse via a fake bone or bone graft. The use of waste from the food industry is how to recover from profuse material source, the enrichment of chemical diversity, at the same time it also reduces the influence caused by the accumulation of waste in the environment.

So far, the use of artificial materials as a substitute for real bones are the most common therapies used to treat osteoporosis. Treatment methods based on the picture frame mold is hard, hollow made ​​of biocompatible materials. This pattern will provide mechanical stability and promote the development of new bone tissue, helps regenerate it.

Calcium phosphate artificial often used as molds and external coating of orthopedic implants because of its similarity to components of bone. Brewery waste is composed of waste organic malt, never underwent the conversion then. This is why the brewery is regarded as by-products, commonly used to make animal feed, and it's not expensive. The analysis of the components of this material showed the presence of interconnected pores of 50 to 100 microns in diameter similar to the porosity of cancellous bone. All this will facilitate the complete circuit distribution after transplantation of bone.
