Steve-Last-conf-podiumThe IPPTS Associates, Anaerobic Digestion Community Website offers consultancy services and promotes and develops anaerobic digestion and biogas production.

The production of biogas is now very much a proven technology, and AD Technology is bringing big benefits to the rapidly rising number of people that are investing in it. But, we are still finding that a large number of its potential beneficiaries are not aware of the true potential of the anaerobic digestion process.

Our mission is to spread the word about the benefits of anaerobic digestion and biogas production.

This “Anaerobic Digestion Community Website” is maintained as an independent website by EurIng Steve Last BSc CEng MICE MCIWM CEnv.

I have worked as an environmental consultant, for more than 20 years, and for most of that time I have been providing advice on waste processes, to the Waste Management Industry.
