New composite based on brewery waste to improve the production of fiberboards

Escuela Superior Politecnica del Litoral

Globally, the food industry generates around 1.3 billion tons of waste per year, which has caused environmental problems such as habitat loss, greenhouse gas emissions, climate change, and pollution. The National Institute of Statistics and Census (INEC) has estimated that in Ecuador, approximately 14.4 thousand tons of waste are generated despite regulated legislation, and the brewing industry accounts for a significant portion of this.

Promising results were obtained by a group at the Brazilian Center for Research on Energy and Materials (CNPEM), working with collaborators elsewhere. They combined inhibition of glutaminase, an enzyme that converts glutamine into nutrients for tumor cells, with inhibition of HuR, a protein that regulates the RNA of glutaminase.
