What are the functions of a biodigester?

A biodigester is a system that decomposes organic waste anaerobically, producing biogas and digestate. The primary functions include breaking down organic materials such as food waste, manure, and agricultural residues, converting them into methane-rich biogas that can be used for energy production. Additionally, the process generates digestate, a nutrient-rich byproduct that can be used as fertilizer, thus promoting sustainable waste management and renewable energy generation.
