EN 16575:2014 Bio-Based Products
Vocabulary
Biomass:
Material of biological origin excluding material embedded in geological formations or fossilized
Renewable material:
Composed of biomass and can be continually replenished
www.greenchemistry.net
Bio-based product:
Product wholly or partly derived from
biomass
EN 16575:2014 Bio-Based Products
Vocabulary
Bio-based content:
Fraction of a product that is derived
from biomass (carbon or total mass
basis)
www.greenchemistry.net
‘Renewable’ materials and bio-based products(as defined in EN 16575:2014) are not necessarily renewed

How to unify these ‘green’ EU economic
strategies?
Circular economy (general legislated targets)ec.europa.eu/environment/circular-economy
Reduce food
waste
generation by
30%
Increase recycling
and re-use of
municipal waste
to 70%
Maximum
landfilling
rate of 25%

Bio-based Renewable Sustainable
Complex with many relevant
criteria
Draft standard (prEN 16751)
lacks quantitative indicators
Describes biomass
utilisation
Environmental impact is not considered
Incorporates full life cycle coverage
Easily validated and understood

Renewability is a bridge
between ‘bio-based’ and
sustainabilityThe concept helps align the bio-based and circular economiesRenewability criteria creates
opportunities for solvents not made from virgin biomass
Biodegradation less relevant to solvents and so other end-of-life
options are valuableChemical recycling can generate solvent from waste products, or
products from waste solvent
