The Growcoon bears the official OK Compost label, managed and controlled by AIB-Vinçotte. OK Compost is a label for compostable products and raw materials. Packaging or products featuring the OK compost label are guaranteed to be biodegradable in an industrial composting plant.

This applies to all components, inks and additives. The only reference point for the certification programme is the harmonised standard EN 13432: 2000, which means that each product with the OK compost logo is guaranteed to comply with the requirements of the EU Packaging and Packaging Waste directive (94/62/EEC).
Composting significantly reduces the volume of organic material. What's more, the compost created can be reused for agriculture and horticulture.
To qualify for this label, the Growcoon has successfully completed the Toxicity test, the Heavy Metal test and the Disintegration test.
