Rendering is one of the oldest and most established recycling processes, taking what would otherwise be waste materials and making useful products such as fuel, soaps and meat and bone meal etc. At the same time, rendering solves what would be a major disposal problem.
Many manufacturers operate a quality assurance policy which includes strict specifications on meat meal supplies and routine testing. As such, the rendering industry must carry out compositional analysis for nutrients such as, moisture, protein, oil, fibre and ash.
