A positive impact for Humans and Nature, now.
"With natural building materials, HempEcoSystems has decided to serve Nature & Humans and respond to one of the most complex challenges of our time: building healthy and long lasting houses without harming our environment."
-Jorgen Hempel, founder of HempEcoSystems
A material with a long story
Hemp is a gift from Nature: from roots to seeds, fibers and wood, it provides many important and useful ressources for humans.
4000 AC TO 1920
GOOD FOR NATURE / GOOD FOR HUMANS
Our ancestors found local building materials to build their habitat with nature as their sole supplier.
1920 TO 2015
GOOD FOR SPEED / GOOD FOR MONEY
Man invents synthetic building with which to build synthetic houses and buildings.
1990 AND ONWARDS
GOOD FOR NATURE / GOOD FOR HUMANS
Return to nature as direct supplier of building materials.
Harmony between human activities and natural environment is the essential condition of our future
To answer at the same time to environmental objectives exposed notably during COP 21 conference and the stakes regarding public health, we want to change from now on the way of designing and constructing buildings.
Fostering healthy, sustainable living by the reintroduction of natural materials in the housing and building sector, worldwide
To do so, we believe that the answer is in Nature. It's why we developed natural, sustainable, bio-based materials as a unique alternative to current carbon-based solutions to:
build and renovate all kind of buildings with high energy efficiency and very low carbon impact
provide inhabitants with a safe, healthy and comfortable indoor climate
act now to make an environmental and social impact and change the way we build.
Our solutions benefit to both Humans and Nature, in the respect of legal and safety regulations.

Short story of Hemp Eco Systems and our product
The use of a wasted material
Some 20 years ago, french Yves Kühn and danish Jorgen Hempel discovered and developed Hemp as a promising building material. The Cannabis Sativa, also known as industrial hemp, produces seeds and fibers, while the stem (wood) was a waste material. It was also discovered that this wood contains a high percentage of Silica, which made it resistant to fire and rot. This was precisely what was necessary to make a valid building material. The wood was chopped up, wetted and mixed with different binders, principally lime (Calcium carbonate).
A test market
The hemp/lime mixture became a most efficient insulation material and its qualities as a humidity regulator was discovered. Hundreds of houses were built and renovated mainly in France during the 90s, for the ecological oriented market.
A global concern emerges
During the first decade of the 2000s, the world became concerned with energy, pollution and depletion of raw materials which suddenly gave the product new perspectives.
The re-discovery of hydrated lime
During the years 2010, Jorgen Hempel and his technicians became aware that hydrated lime (pure Calcium Carbonate) would be the ideal binder for the hemp. Calcium Carbonate exists in abundance all over the world, transformed into powder and humidified it carbonates and slowly returns by a natural process to its original state of Calcium Carbonate by taking up CO2. This type of lime mixed with hemp would be the ideal low energy consuming and zero polluting building material, able to produce a CO2 free, alkaline indoor climate for health and well-being. The problem was that the lime needed 4-6 months to cure.
An invention to solve a 2000 years problem
This problem was studied and after many trials, 4 natural minerals that would cure the lime in 1-2 days without losing the precious uptake of CO2, were found. A patent was filed and HES won the 1st prize at the international Bio-material conference at Cologne in April 2014. We had solved a 2000 years problem and possessed now a unique material that responds to all requirements of the future: using nature as a supplier, natural clean materials, energy saving, humidity regulating and foremost good for people's health and well-being.

Why zero-consumption house is a wrong concept
Locking up a house to become a zero-consumption house is a wrong concept for the following reasons:
Who has asked for zero-consumption to start with?
Millions of existing houses and buildings are over consumers of energy, because neither materials or well -studied concepts were available when built.
How should we correct this situation ?
A reasonable attempt would therefore be to reduce the energy consumption in those 90% of all buildings, by for example 50%.
We are here talking of billions of savings and emissions per year and this is perfectly possible.
It is of no use to build and insulate with synthetic materials, deriving from fossils and minerals. To convert these raw materials to usable building and insulation materials require such amounts of energy and cause excessive CO2 emission to an extent that it will take longer than the economic life of the building to recuperate the energy or CO2 consumed and emitted during production.
The development of modern energy saving buildings and insulation products has been based on retarding migrating warm and cold or by locking up houses and buildings hermetically. The non- breathing effect thus produced has given serious negative results which should not be tolerated. If we consider moisture as the main enemy in a house or building, it is also the most uncontrollable.
Condensation will build up on any non-breathing membrane by simple exposure to cold followed by warm or vice-versa.
No development or invention should be made and sold on the market, without taking all effects, from birth to life end, into consideration. We must consider both positive and negative effects and set reasonable priorities. The question is how long can we afford to save on energy when we, at the same time, cause damage to nature and to the health of those living in houses and buildings?
