Cost reduction

Production costs reduced from 800 to 200 EUR/m² - sustainable and competitive.

A diagram with four bars and an ascending line with a leaf symbolizes growth and progress.

Industrial strength

Reference project OPENLY Valley Widnau - Europe's largest hemp building with 1,500 m² of wall space, completed in just 30 days.

At Cancret, we are redefining the future of construction with our patented technology for horizontal prefabrication of hemp-lime walls. Our solution transforms timber construction companies into pioneers of the sustainable building revolution by expanding their added value and turning buildings into efficient CO2 sinks.

Cancret Technology binds CO₂ in houses

Proof in practice: OPENLY Valley Widnau shows what is possible: industrial scalability, speed and sustainability all in one. With CANCRET, every construction project becomes a showcase for the future.

Natural materials
Impressive performance

Hempcrete binds more CO2 than is released during its production (-100 kg/m³ compared to +220 kg/m³ for normal concrete).
It transforms buildings into certified carbon sinks and supports global climate goals.

CO2 negativity

With an insulation value of 0.06-0.07 W/m-K, Hempcrete ensures excellent energy efficiency and reduces heating and cooling costs. At the same time, it offers fire resistance (EI120 at 12 cm plastered) and natural mold resistance, ensuring safety and durability.

Thermal insulation

Hemp grows regionally in just 110 days, requires little water, can be cultivated without pesticides and provides around 7 tons of building material per hectare - a renewable resource with a minimal ecological footprint.

Sustainable raw materials

With a weight of just 350 kg/m³, Hempcrete makes construction easier, reduces transportation costs and relieves the load on the statics - perfect for modern, efficient timber construction.

Lightweight construction

By binding CO2, Hempcrete enables the purchase and trading of CO2 offset certificates. Building owners and companies can thus generate additional income with milton.earth and monetize sustainability.
