The REDcert² certification scheme for sustainable biomass has expanded its scope: the scheme is now also applicable to a new, highly complex sector – the chemical industry.

The certification system REDcert² ensures that the European sustainability requirements for the use of biomass for energy and material purposes are met at all levels of the production process. Currently, the certification is mainly used by the biofuel, food and beverage industry. Due to the highly complex manufacturing processes, the REDcert² certification was not applicable to the chemical industry – with the launch of a supplementary principles for the chemical industry, this has changed.

The highly complex production processes of chemical products pose a major challenge for providing evidence that fossil-based raw materials have been replaced by sustainable biomass. Both sustainable biomass and fossil-based raw materials are used as sources of raw material in the production processes at the same time. These are then first broken down into atomic or molecular components, separated and then incorporated into a variety of products. The sustainable biogenic content in these products can vary considerably, making it virtually impossible to reach a valid conclusion about the content in the end product based on analytical evidence as a result of large-scale chemical compound processes.

Supplementary System for the Chemical Industry

In order to account for the special requirements of the chemical industry, REDcert² created a new methodological approach, which can be used as an alternative to traditional “mass balancing”. It is based on the essential principles of the CMS 71 standard and and balances individual atomic components of sustainable biomass on the basis of their energetic valence and is based on an equivalence analysis according to defined “formulas” for manufactured products. This standard, originally published as CMS 71, was exclusively adopted by REDcert and integrated into the REDcert² scheme as an optional approach to meeting the needs of the chemical industry.

REDcert² certification

For the production of REDcert² certified products, the biomass used in the chemical production process must also be certified as sustainable and a valid REDcert² or REDcert-EU certificate must be available as proof. Alternatively, REDcert² also accepts biomass from other sustainability schemes, provided they are recognized by the European Commission, approved by the Sustainable Agriculture Initiative (SAI) or got certified by FSC or PEFC.

Advantages of the REDcert² certification

  • The REDcert² certificate offers new perspectives to the chemical industry and methodical approaches for the sustainable substitution of fossil resources – an active contribution to climate protection
  • The REDcert² certificate substitutes a minimum of 20% of the used fossil resources with an equivalent quantity of sustainable certified biomass. As a certificate holder, you can use this as a competitive advantage
