Gaia EnviroTech is a bioenergy and waste management company based in Regional Victoria. Our focus is on solving two critical challenges that many industries face; the ever increasing cost of managing high volumes of organic waste, and the ability to source on demand renewable energy solutions to run business operations and reduce carbon footprint.


Based in the regional Victorian city of Ballarat, Gaia EnviroTech was born out of a conversation between Gekko Systems Technical Director, Sandy Gray, and a local pig farmer, Jock Charles, who had been running an anaerobic digester on his pig farm for over 20 years treating pig manure.
The conversation revolved around the question of why waste to energy solutions are not more utilised in Australia. Not only will the application of bioenergy help solve the ever growing waste problem, but it will also contribute to reducing carbon emissions.
Utilising Gekko Systems’ 25+ years as a leader in the mining, technology and services sector (METS) and the company’s extensive engineering and design capability, the Gaia EnviroTech anaerobic biodigester, and rapid composter were invented and successfully commercialised. Gaia EnviroTech continues their strong partnership with Gekko Systems.
Gaia EnviroTech now provides end-to-end waste management and bioenergy solutions that are modular, scalable and designed for the local context.
