Quick Summary

Biofragmentation is a stage in the biodegradation process where saprotrophic organisms excrete enzymes that break down a material's molecular weight. This process typically involves reducing polymers into smaller units like dimers and monomers. These smaller organic chemicals are then further broken down through either aerobic digestion (with oxygen) or anaerobic digestion (without oxygen), which can produce methane. This stage prepares the material for assimilation by organisms, where the fragmented compounds are absorbed for energy.1
