To clean the air of pollutants such as methanol and solvents used in the industry, biotechnology expert Raul Pineda Olmedo, of the National University of Mexico (UNAM), designed a biofilter that uses microorganisms living in the shell of the peanut.
The research from the department of Environmental Technology noted that microorganisms grow naturally on peanut shell, which can be used to clean the air. Furthermore, in Mexico this material is generated in large amounts and is considered a worthless agricultural residue.
