Ecology of the hemp stones
Ideally suited for building sustainable
Building for grandchildren and the environment
We now know that 30% of CO2 emissions come from the construction industry, as well as 50% of all waste and 40% of all energy consumption.
The average useful life of a home in the EU is 30-50 years. After that, it is often hazardous waste because the materials used can no longer be separated or are simply too expensive.
The construction industry is the main source of enormous resource and energy consumption.
In order to pass on not only our homes but also an intact and living environment to our children, we need innovative building materials. We also find them in the raw materials of our ancestors. They are of natural origin, renewable, recyclable and durable. They store CO² and are healthy. Made from natural raw materials, hemp limestones are a modern solution for efficient and future-oriented building.
Hemp and lime - that makes sense
The symbiosis of the oldest cultivated plant of mankind, hemp, with one of the oldest and most proven building materials, natural lime, results in the building material of the future: hemp limestone.
The hemp plant grows about 50 times faster than wood. On one hectare of hemp field, the biomass for a small family house grows in only 5 months.
The combination of loose hemp seeds with natural lime and minerals makes the material rock-hard and resistant to external influences, which means the building will last for many generations. This protects the environment and saves money.
Its excellent thermal properties make additional insulation such as polystyrene unnecessary. Hemp lime has similar properties to clay in terms of air purification and moisture regulation, ensuring a healthy climate and clean air.
CO² balance: minus 90%
According to calculations in EN 15804, approx. 90 % more CO² is stored in the hemp stone than is released during production, resulting in a balance of minus 90 %.
The cycle retains more CO² than it releases and thus actively relieves the environment.
After use as a building material, hemp limestones can be composted to improve the soil or crushed and enriched with a little lime and reused as (loose) building material.
Incidentally, hemp hurds, of which the stone essentially consists, are a residue from the extraction of hemp fibres. Hemp lime is therefore a true cradle-to-cradle miracle.
