Biogas Digester

Products Biogas Digester Eden Developments

Biogas Digester takes organic waste and creates a flammable gas.  A large tank is filled with bacteria which eats (digests) the organic waste which then emits the methane gas.  The gas is produced inside the tank which can then be used for cooking and any other household energy needs.  Waste that has has been digested exits the biogas system in the form of organic fertilizer.

Eden Developments offers a Biogas Digester solution which is a cost effective way to create further energy efficient savings.  Clients will have a never-ending supply of gas which can be used in the home as well as having compost for the garden, along with nutrient enriched water to be used in the garden.

Water Collection System

For the water collection system, we encourage the use of water tanks for the collection of rain water which can then be used, after filtration, in your home as drinking water (no more purchasing of filtered water), general water use and if you have enough capacity, in your garden.


The sizing of this system will depend on the space you have available for tanks and if you want to look at an above-ground or an underground water system.
