Carbon dioxide (CO2) is a colourless, odourless gas produced by burning carbon and organic compounds, and by respiration. It is naturally present in air (about 400 parts per million1) and is absorbed by plants during photosynthesis.
The Linde Group supplies CO2 into many countries. A significant amount of the product is re-captured from industrial processes. This re-captured CO2 is then condensed and purified, allowing it to be sold in cylinders or in bulk to a range of specifications, from food grade to industrial or agricultural grade.
CO2 is a versatile molecule, supporting growth in plant life whilst also serving as a useful pest control tool. It is considered an organic treatment in many countries which means that the addition of CO2 into the greenhouse or as a post-harvest treatment for produce will not impact the organic status of your produce. Consequently, with the growth in demand for organic produce increasing steadily internationally, CO2 is part of the solution for many farmers and storage facilities worldwide.
CO2 may be regulated for use as a fumigant or for use in greenhouse applications in your country and CO2 safety monitoring should be conducted during applications. For more information, please contact your local Linde representative.

Each fumigant is subject to local regulatory approval. Please refer to the local product specimen label for details of locally approved crops and pests. The global crop science team can provide you with details and availability of product for trials or commercial use.
