What is the ‘fart rate’ of different composting systems?

Papatuanuku Kokiri Marae, Koru Primary, Sustainable Coastlines and Ngāti Whatia Ōrakei are investigating whether adding microbes to food waste changes how much gas is made as it breaks down into compost.

This team is looking at the change in gas levels (carbon dioxide and methane) in a sealed composting system measured over 4-6 weeks, from decomposition of unassisted vs microbe-assisted organic kitchen waste.

They are exploring, with students and whānau, the process of composting and the science behind decomposition of organic material, carbon dioxide and methane gas production, and the difference adding a microbial starter can make.

They are doing this because they want their marae community to understand how composting works, why it’s a good idea and how they can support Para Kore (marae zero waste programme).
