Biorefinery


looking into (far) future

Energy vs. “use as matter” (chemicals, materials, food, feed)

Renewable resources

Biorefineries

Time

Fossil resources

Petrochemistry

(Energy and chemicals)

We need “
CARBON
” to produce materials and chemicals.

We don’t necessarily need “
CARBON
” for energy production.
