Patented hemp-lime walls for the building sector: sustainable, industrially scalable and certified.
CO2 reduction era has begun
At Cancret, based in Switzerland, we develop, trade and license industry-changing technologies, products and patents. The central basis for these innovations is the targeted use of industrial hemp. Thanks to its unique properties, it also improves the sustainability, cost efficiency and user comfort of your new buildings or renovations. Cancret Materials supplies patented hemp-lime prefabrication for industrial timber construction: CO2-negative, industrially scalable and certified.
-100 kg CO2/m³ compared to +220 kg/m³ for concrete

International licensing of the developed hempcrete patents and trading of best-in-class products without production risks and decisive incentives for production partners.
Our vision: Cancret Materials will become the global market leader for hemp-based building materials by 2028 and establish CO2-negative buildings as the global standard. With hemp lime - the superstar of sustainable building materials - we not only build smarter, but also greener: -100 kg CO2/m³ compared to +220 kg/m³ for concrete. Become part of our vision. We can also independently test and certify these savings for you.
The central basis for Cancret Materials' innovations is the targeted use of industrial hemp.
Hemp lime as a CO₂ sink superstar
Hemp lime, a mixture of hemp hurds and a lime-based binder, stands out as a top candidate. Industrial hemp grown annually binds around 21.1 tons of CO₂e per hectare (at 12 tons of dry matter with 48% carbon content). Processed into hemp lime, it stores this carbon in buildings for decades and creates a temporary carbon sink with a lifespan of at least 60 years. For example, 1 ton of Hempcrete contains around 200 kg of CO₂e bound carbon. This makes hempcrete a climate-positive building material. The standard also introduces C-sink options that make future climate benefits tradable after annual verification.
