The development of a sustainable society is heavily depended on the realization of a transition of the economy of today which is heavily dependent on fossil and mineral resources towards a biobased economy. Therefore new production chains and development
The transition towards a Bioeconomy requires new approaches for food production, energy supply, use of materials and production processes. Existing value chains will have to be re-examined against the new criteria set by the integrated biobased economy. This will lead to a ‘re-valuation’ of raw materials, intermediates, products and waste streams as well as water and energy consumption which is shown in the following value-pyramide.
This value-pyramide classifies the biomass according to its value of applications as indication on how the limited supplies of biomass can be used most efficiently.
The 4 domains are:
Food --> Pharma (Health), Food Ingredients, Functional foods, Food
Feed --> Feed ingredients, feed
Functional materials --> Fine chemicals, performance materials, bulk chemicals, fermentation, fertilizer
Fuels --> bio-fuels, fire, flare, fill
The cascading use of biomass shows a mechanism for prioritizing its use for socially preferable products, notably materials over its use for energy. Such a mechanism is an opportunity to maximize the efficiency of the biomass usage.
