Waste fats, oils and grease present an immense challenge to communities across the globe. Generated in massive quantities as a byproduct of cooking protein, FOG can damage wastewater infrastructure, cause sewer backups and harm wildlife, water and land resources. Collected FOG primarily ends up in landfills where it decomposes and releases greenhouse gases. Fortunately, a safer, more ecological path exists for the FOG waste stream. When separated, FOG becomes an excellent source for biofuel feedstocks. This blog will explore the challenges, benefits and potential of FOG waste for the world today.
