This concept is called “The Biomass Balance Approach”. This approach is applicable
to almost all fossil-based products in the chemical industry (see Fig. 1, [2]).
Certified renewable feedstock (e.g. biogas derived from organic waste) replaces
fossil resources at the beginning of the value chains in the chemical industry. Then
the renewable feedstock is attributed verifiably to sales products in the corresponding quantities (see Fig. 2: comparison to bio-based chemistry). Third-party
certification (TÜV SÜD) confirms to customers that BASF has used the required
