A modular system for boosting biogas production from waste

Agriculture & Energy

A new process is turning food waste that would end up in landfills, into natural gas and other valuable by-products instead

Spotted: Organic waste makes up a huge proportion of all municipal waste, with around 17 per cent of global food production going to waste at the retail, restaurant, or household level. But what if that food wasn’t all wasted? What if some of it could be turned into renewable energy? That is the question being answered by New Zealand clean-tech startup Cetogenix. 

Cetogenix has designed a modular system for breaking down organic waste to generate renewable energy and other useful by-products, such as fertilisers and biodegradable plastics. The company’s technology uses a combination of chemical and microbial processes, which can be located at source and easily scaled. 

The flagship product, called CETO-Boost, is currently under development. When complete, it will allow a 40 per cent increase in the production of renewable natural gas from anaerobic digestion plants. It will also be capable of being retrofitted, and the company has identified more than 15,000 anaerobic digester plants that could benefit from this retrofitting. 

Cetogenix secured $4.5 million(around €4.1 million) in a 2022 seed funding round led by deep-tech investor Pacific Channel, with support from angel investors. The investment is being used to scale up the company’s technology and enable global deployment, with an initial focus on Europe and North America. 

This technology aims to tackle both organic waste and natural gas issues at the same time. In the archive, Springwise has spotted other methods for tackling these issues, including turning organic waste into bio-plastic and using methane pyrolysis to generate green hydrogen.
