Boost Yield
Carbon is almost half of the dry weight of plants and is the key building block of all living matter
Plants fix carbon from CO2 in the air, but ambient levels of CO2 aren’t nearly enough to maximise plant growth in high-tech greenhouses where all other growth variables can be maximised.
The benefits of CO2 enrichment on crop yield in most fruits, vegetables and flowers grown in greenhouses is well documented. Increases in crop yield of as much as 30% can be gained through enriching a greenhouse with CO2, increasing grower revenue and profits.
The graph on the right shows crop production at different CO2 concentrations and is based on data from about 60 publications of experiments worldwide in many greenhouse crops (Source: Elly Nederhoff, 1994).
Our containerised rapidly deployable CO2 and heat production systems allows rapid transport and installation and will enrich 3-4 Ha of hydroponic greenhouse to ~700ppm, at around half the price of existing CO2 sources where available.

Clean and Safe CO2
The CO2 produced by the Hot Lime system is guaranteed to be clean.
Gas cleanliness is constantly monitored by a range of electronic sensors in the Hot Lime system. This ensures levels of CO, Ethylene, NOx and SOx are all within safe limits – if gas is found to be outside of ‘safe’ levels, the system will automatically stop feeding into the greenhouse. Gas output has also been independently tested.
The system also has very low particulate emissions due to the updraft gasifier design system and filtering by the Hot Lime material.
“Access to a cost-effective CO2 supply would be of huge benefit to our growers. CO2 has a significant impact on greenhouse crop productivity and can increase yields by up to 30%. Most growers can’t get enough, and South Island growers can’t get any. A renewable source of CO2 would be greatly welcomed by our industry.”

Biomass Conversion
The system currently converts a range of wood waste into CO2 through our novel process. In future, the system will broaden to be able to convert other waste biomass such as crop waste, waste oils and anaerobic digester gases.
Greenhouse Integration
The Hot Lime Labs system is containerised and currently standalone from any of your other greenhouse systems. It can be integrated into an existing greenhouse set up, including in a new build, and it sits separately from your existing boiler system.
The Hot Lime system does not replace your current boiler system, but it does augment it. The Hot Lime system will produce 20-30% of the heating needs of a 3-4Ha greenhouse across the year, or enough to meet all your heating needs during summer. We can integrate the system with your buffer tank, and contribute to your overall heating needs.
The system footprint of each installation is as little as 250m2, with additional space required for wood storage.
The patented lime pellets will be replaced annually in your system to ensure the system runs efficiently.
The system is fully automated and needs minimal daily maintenance at the greenhouse.
