Hot Lime Labs is a world-leading brand that specializes in the production of clean and sustainable CO2 for the horticulture industry. Using innovative CO2 capture technology, we extract CO2 from waste wood and other biomass, providing a green alternative to the traditional fossil-based sources of CO2. Our patented limestone pellets combined with novel engineering techniques allow us to produce clean CO2, a vital plant nutrient used in high-tech hydroponic greenhouses.

Not only does this help growers reduce their carbon footprint, but it also offers access to CO2 for those who previously couldn't obtain it. Our mission is to help transition 50% of the global greenhouse industry to renewable energy within the next 30 years, reducing fossil CO2 emissions. To achieve this, we aim to partner with biomass boiler manufacturers to offer an all-in-one solution for heat and CO2 to growers.

Founded in 2017, Hot Lime Labs originated from technology developed at Callaghan Innovation and has since grown into a successful company dedicated to decarbonizing the greenhouse horticulture industry. With a team of skilled and dedicated individuals, we are committed to innovation and sustainability in the horticulture sector. Join us in our mission to create a more productive, efficient, and sustainable future for greenhouse growers
