Patented Hemp-Lime and Clay Wall Systems
Wall systems for architecture with significantly reduced CO2 emissions
At Cancret, we develop, manufacture, and license industry-transforming technologies, products, and patents using natural, renewable building materials.
Thanks to their unique properties, these solutions enhance sustainability, cost-efficiency, and user comfort in both new construction and renovation projects.
Better, healthier, cost-neutral.
The superstar of carbon-negative building materials: hemp-lime
-100 kg CO2/m³ compared to +220 kg/m³ for concrete
-
Worldwide unique patents for prefabrication of Hempcrete walls and an impressive development pipeline.
-
Hemp grows in 110 days, requires little water, is pesticide-free and provides material for two 3-room apartments per hectare.
-
The excellent insulating properties of hemp lime lead to energy savings and improved user comfort thanks to diffusion-open walls.
-
Europe's largest hemp building(OPENLY Valley Widnau) - built with our technology.
-
Cancret AG has reduced production costs from 800 to 200 EUR/m² through the patented production process for hemp lime walls - scalable and profitable.
-
International licensing of the developed hempcrete patents and trading of best-in-class products
Our vision: Cancret Materials will become the market leader in the distribution of sustainable building materials and establish carbon-negative buildings as the global standard.
Be part of this vision with your project.
The central basis for Cancret Materials' innovations is the targeted use of industrial hemp.
Hemp Lime as a CO₂ Sink
Hemp lime, a mixture of hemp shives and a lime-based binder, stands out as the top contender. Industrial hemp grown annually sequesters approximately 21.1 metric tons of CO₂e per hectare (based on 12 metric tons of dry matter with a 48% carbon content). When processed into hempcrete, it stores this carbon in buildings for decades, creating a temporary carbon sink with a lifespan of at least 60 years. For example, 1 m³ of hempcrete contains about 100 kg of CO₂e in bound carbon (net). This makes hempcrete a climate-positive building material. The standard also introduces carbon sink options, which make future climate benefits tradable following annual verification.
