As well as producing commercially valuable biogas, anaerobic farm digesters have many other benefits. They enable the livestock farmer to recycle fertilizer from organic waste, to produce saleable compost as a byproduct, and reduce the environmental impact on water
and atmosphere at the same time. Digesters let us run farms more economically, and make our energy supplies and our food production more sustainable.
