A question about biogas production using Opuntia

related country: United Kingdom of Great Britain and Northern Ireland

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?

1 Answer


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


Micha, this clearly means that using Opuntia as a feedstock is more complex and therefore more expensive, but is there work being done by any NGOs to investigate it still? Harriette
