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
