Our values



Our economies and more generally our societies face existential environmental challenges for which we must anticipate and find solutions. We want to offer some of the solutions.



Sustainable development is at the heart of our project. Our supply will be local and we aim, as much as possible, for a local clientele. We are aiming for zero releases into the environment. Our human-sized factory model is a departure from existing "world-class plants".



Our activity is a source of direct and indirect jobs generated in transport, logistics and the agricultural sector. Our model is also very easily integrated into the agricultural ecosystem.

Biosourced molecules

A local project

We created Prevcarb in March 2021, in Normandy (France) and we work for the global transition towards a circular and low carbon economy. Our field: the transformation of non-food biomass. We supply the chemical industry with three biosourced platform molecules: lignin, cellulose and hemicellulose obtained from flax shives. Our action is built in a local perimeter for the respect of the environment.

Our skills in chemistry, project management and finance are the fruit of a long experience and our convictions in favor of the exit from oil compel us to act now. We believe in valuing our biomass as an alternative to fossil fuels and implementing the processes.

A virtuous awareness.
France is the leading producer of flax in the European Union. The earth is a source of resources that we have to protect and enhance. To be aware of this is necessary as we speak.

Flax fiber production sites

16 cooperatives (SCA)
14 private companies (SA ou SARL)

Harvested area in 2020
141 396 ha

For oilseeds, the straw yield produced varies between 2.9 and 13.8 tons of dry matter (tMS) per hectare depending on the region and the species (rapeseed, sunflower, soybean, oilseed flax, camelina and mustard). Only rapeseed straw is considered technically harvestable, at 40% due to significant material losses during mowing operations.

No straw harvesting practices could be identified for the other oilseed species. The national theoretical available volume (TAV) is 1.1 million tMS, excluding return to agronomic soil.

The minimum return to the soil (buried or left in the field) to maintain the agronomic potential of cultivated soils varies from 27% of the DTV in the Occitanie region to 96% of the same volume in the PACA region.
