Home Flexigester V10 inflated for testing

Designed for small communities and farming groups the Flexigester V10 can be packed into a single crate and sent by air freight to most parts of the world. It is simple to install and easy to use.

The Flexigester System is an innovative anaerobic digestion system that can take materials such as animal manures, waste food, human waste and plants and convert them, over a period of several weeks, into natural Biofertiliser and Biogas.

The Biofertiliser contains plant nutrients, including those found in artificial chemical fertilisers, which can be used on the land.

The Biogas can be used as a fuel for cooking and is a cleaner and more sustainable alternative to wood or charcoal.

The waste materials are not exposed to the atmosphere which prevents flies and vermin living and breeding on them.
