Biooil application:
Alternative fuel for small and public energy production (application in boilers as replacement for petroleum derived heating oil and fuel oil.
Components of motor fuels
Binder for composite materials (production of biopolymers, replacement of phenol in phenol- formaldehyde resins, replacement of polyols in polyurethanes up to 30%):
Feedstock for road construction (addition to bitumen as adhesive up to 30%);
Feedstock for chemical industry (separation of useful components, rectification, production of oils and motor fuels).
