In a study published in Frontiers in Sustainable Food Systems, researchers detail how they have created an eco-friendly pesticide using beer bagasse (spent beer grains), rapeseed cake (byproduct of oil extraction from seeds) and fresh cow manure.
Chemical pesticides have been proven harmful to the environment, damaging soil and water. Pesticides are also easily consumed, and many studies link their use to multiple diseases and birth defects. Researchers from the Neiker Basque Institute for Agricultural Research and Development in Spain hope that farmers will use these organic byproducts from beer production to kill parasites, preserve healthy soil and increase crop yields.
