Biogas and Anaerobic Digestion Safety
It’s unpredictable and can kill quickly – even in spaces you’ve entered before without incident.
Manure gases are readily and rapidly generated by the microorganisms found in raw manure. Covered manure storage and collection pits, covered lagoons, upright storage tanks and tanker spreaders are examples of places where manure gases can accumulate to deadly levels.
An anaerobic digester is a managed temperature waste treatment facility used to biologically treat waste as a component of a waste treatment system.
