Using world-leading CO2 capture technology, Hot Lime Labs produces clean and sustainable CO2 from waste wood and in the future, other biomass. Our technology uses patented limestone pellets combined with novel engineering to produce clean CO2, a key plant nutrient used in high-tech hydroponic greenhouses. This allows growers to reduce their carbon footprint while being more cost-effective, providing a green alternative to the traditional fossil-based sources of CO2: natural gas and liquid CO2.
Hot Lime Labs was founded in 2014 using technology originally developed at Callaghan Innovation. Dr Vlatko Materic, founder and CEO of Hot Lime Labs, had been researching and working on CO2 capture systems for large scale thermal power plants for over a decade at the former government research institute, Industrial Research Limited – now Callaghan Innovation. It was during this time he developed the Hot Lime capture technology.
The technology showed great promise for this application, however, the economic drivers did not exist for power plant operators to justify the additional costs of installing and operating CO2 capture system using the technology. Fast forward 10 years and Vlatko discovered the vast unmet demand for clean CO2 in the greenhouse industry and quickly found that both technology and commercial drivers were well aligned.
Vlatko founded Hot Lime Labs and secured its first private investment in late 2017. To date, he has led the company from initial ideation, growing the team to now commissioning the first pilot plant with a leading New Zealand commercial grower.
At Hot Lime Labs our goal is to decarbonise the greenhouse horticulture industry, enabling greenhouses to be not only highly productive and efficient but also sustainable.
The growing team behind Hot Lime Labs is made up of a diverse range of skilled, educated and hard-working people. We are a close-knit, like-minded team. We don’t hire people to fit into roles, more fit a role around a person. This allows us to not only build innovative technology but also our people and ensure we are doing what works.
