AGAMA BiogasPro at UCT

Biogas Stove in the Kichen

UCT residence, Leo Marquard Hall, has been cooking off biogas since about August 2011! A really incredible achievement that has remained unbeknown to most students for the last year.


The project is a partnership between UCT Department of Chemical Engineering and AGAMA energy. An AGAMA BiogasPro unit has been installed in the garden outside the Marquard kitchen and is producing gas from food waste from the kitchen. 

Think about what this means - the students at UCT are eating food that was cooked on last week's left-overs! 

The project aims are : to show that biogas digesters are in fact viable waste to energy solutions  in urban settings, to show students how feasible sustainable energy systems can be, and to take constructive steps forward in the university's broader goal of reducing greenhouse gas emissions, and becoming a carbon-neutral campus.  

There have been many articles written about the Leo Marquard digester, and the most interesting ones are linked below.

Also, take a look at the video that shows how the system works.

    This is really encouraging.

    If only more businesses, communities and establishments could get their shit together with this kind of innovation.

    I'm proud of UCT for doing this. Now for the rest of campus...

    Talking about shit, if they powered their digester with sewerage they could all all have hot showers off the grid.
    The real trick is to grow food with the waste water.
    Well done UCT. Brilliant project.

      Hi. Yes, indeed the opportunities are MUCH wider than currently explored at UCT. These wider benefits did not form part of the more narrow research focus that the current project serves, which are more to do with the concept of embedded biogas systems in the 'urban landscape'. As you note: there is a much wider energy potential remaining untapped, while re-use of the digestate would reduce the payback period to just a few years ... cheers!

    Correction: Human waste = not good feedstock

      Indeed. We often steer people away from including sewage if they already have a sanitation solution to hand, so that the re-use of the digestate can happen at effectively zero cost.
