A question about biogas production using Opuntia
A question from Graham: Biogas is being produced commercially in some developing countries using Opuntia as feedstock. There seems to be no effort by NGOs to investigate its potential for providing energy for poor people though very easy to digest in simple digesters, am I right?
In order to digest Opuntia a more sophisticated technology is necessary. Simple household digesters will soon come to their limits. especially pretreatment will be necessary.
Mit freundlichen Grüßen / Best regards Michael Köttner
