Carbon makes up about 45% of the dry weight of plants and is arguably the most important element to plant structure
Plants fix carbon from CO2 in the air, but ambient levels of CO2 aren’t nearly enough to maximize plant growth, especially 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. The wide band is due to variation between crops and to conditions. This graph is based on data from about 60 publications of experiments worldwide in many greenhouse crops (Source: Elly Nederhoff, 1994).
Our containerised HL3000 system allows rapid transport and installation and will enrich 3 Ha of hydroponic greenhouse to ~700ppm (or 2Ha to 1000ppm), at around half the price of existing CO2 supplies*. Increasing the number of units feeding a greenhouse can increase the concentration of CO2 within the greenhouse.

Clean and Safe CO2
The CO2 produced by the Hot Lime system has been certified by independent labs as clean and safe for crops and people. Gas cleanliness is also constantly monitored by an array of electronic sensors, to ensure levels of CO, Ethylene, NOx and SOx are all within safe limits.
The system also has very low particulate emissions due to the updraft gasifier design system and filtering by the Hot Lime material.
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. Stay tuned!

The Hot Lime Labs system is containerised and standalone from any of your other greenhouse systems. It can be integrated into an existing greenhouse set up, included in a new build, and it sits separately from your existing boiler system.
The Hot Lime system does not replace your existing boiler system, but it does augment it, with the HL3000 producing approximately 10% of the heating needs of a 3Ha greenhouse. We integrate the system with your current boiler.
The system footprint is two 20” shipping containers, 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 by the greenhouse customer.
How to buy
Customers will buy clean renewable CO2 through a supply contract with Hot Lime Labs; this means that you pay for the CO2 and heat produced through the system that is fed into your greenhouse. We will install our system(s) on your site, connect with services and sort wood feedstock. This takes the hassle and risk out of your hands, and there is no costly equipment purchase needed.
HL3000 will be available for commercial use from late 2020 – contact us today to discuss your needs.
