Flexi Biogas Solutions are the cleanest, greenest, most affordable & sustainable, portable and simple to operate biogas system yet developed.

The fabric is manufactured to last over ten years, and we further enhance its lifespan can be enhanced by applying a sunscreen UV block solution every seven years. We further enhance the lifespan by housing the system in a Micro-greenhouse tunnel that not only shields the digester against the harmful effects of direct solar UV rays, but also enhances and maintain high temperatures that increase the fermentation process and hence delivering unmatched efficiency and performance. The tunnel also shields the system from farm animals and critters such as children who believe the system is their personal bouncing castle ..
