Recovering and recycling by-products
After extracting and separating liquids from gases, the multiple marketable components – in particular tars and vegetable oils – are separated using various methods, especially distillation.
These substances then have several uses in biochemistry.
The tars are refined in order to obtain different variants based on their use, in particular for pine tars:
Tree growing: to treat tree wounds;
Horseback riding: grease for horses’ hooves;
Hunting: to attract wild boar who coat themselves in tar to get rid of parasites.
These oils combine several components found in wood. Each wood variety contains different molecule chains for which uses can be found in food-processing, cosmetics, the chemical industry, etc.
