Anaerobic digestion

Anaerobic digestion is a biological process in which bacteria break down organic matter in the absence of oxygen.

A biodigester or digester is an airtight enamel steel chamber with a gas proof dome in which anaerobic digestion of manure, biosolids, food waste, other organic wastewater streams or a combination of these occurs.

Maintained at a constant temperature of 37 degrees, over a period of 27-29 days, this anaerobic digestion process produces commodities such as biogas (a blend of methane and carbon dioxide), animal bedding, and fertilizer.  The methane produced is used either in the bio fuel industry or in the generation of electricity and heat.  Additional residue created by the process can be used as a soil improver and liquid fertilizer.

Digesters have been used on a commercial basis internationally for over 30 years and are currently found in the agricultural, wastewater treatment, and food waste management sectors. The benefits of digesters include reduced greenhouse gas emissions, renewable energy production, potential water pollution control opportunities, and financial savings or additional revenue streams.

3R Biodigestor vision

There are multiple designs for the digesters themselves, but they are very inefficient.  3R Consultants are therefore developing a completely new continuous biodigester.

Currently at a scoping stage, the design requires additional research and development, followed by protoyping to prove.

We have a vision to link with local universities and specific industry groups to realise the prototype into production.
