Hybridised sustainability metrics for use in life cycle assessment of bio-based products: resource efficiency and circularity
The development, implementation and social acceptance of resource efficient, circular, bio-based economies require critical understanding of the whole supply chain from feedstock to end-use. Trust, transparency and traceability will be paramount. Though life cycle assessment (LCA) is a universally chosen approach to fulfil this purpose, the nature of data required and the depth of analysis lead to complex interpretations of the findings. Herein, a new set of hybridised, first-line sustainability indicators, drawn from the principles of green chemistry and resource (material and energy) circularity, are reported. These flexible, potentially stand-alone metrics are demonstrated via application to an exemplary comparative LCA, incorporating the hybridised indicators including hazardous chemical use, waste generated, resource circularity and energy efficiency, from the “gate-to-gate” stages for the bio-based case studies and their petro-derived commercial counterparts. These metrics were observed to quantify critical new information relevant to our transition to a circular economy, bridging significant gaps in contemporary environmental impact assessment methodologies. Appropriate additional evaluations that examine the performance of metrics, when the embedded resource efficiency and circularity strategies are omitted, have also been undertaken and reported. The data drawn from employing these methods are crucial to inform and encourage operational optimisation, transparency in sustainability reporting and practices to a significant number of value-chain actors including manufacturers, policy makers and consumers.

A 3-day meeting took place in Leipzig to achieve the results expected within the WP7. The participants from Unibo, DBFZ, TUB, ECOS, USC and UWM worked together on how to assess the ILUC risk of bio-based products, define mitigation options to reduce it and identify a proper methodology for policy recommendations.
The 24th edition of the EURAS Conference will be held in Rome on the 13-15 June 2019. The conference theme is “Standards for a Bio-Based Economy”.

The STAR-ProBio mid-term meeting took place last week in Greece at the Agricultural University of Athens. It was a very useful and productive meeting.
A special thanks to all External Advisory Board and External Review Committee members for their active participation and constructive feedback!
Nine identified bio-based opportunities for the Chemical Industry
In the BBI-funded project RoadToBio with the main goal to develop a Roadmap to show the path to increase the bio-based share up to 25% in the chemical industry until 2030, nine business cases that exemplify the possibilities for the chemical industry to produce more bio-based products have been identified. For further information please follow the link and listen to a webinar held by the consortium on July 11 to present these business cases.
Survey “Key barriers and hurdles on bio-based products – what is your opinion?”
RoadToBio wants to offer you the possibility to express your opinion on important barriers to bio-based products that hinder market uptake. Be part of the journey into a bioeconomy-based future. How? Complete the survey by the 31st August and return it back to the RoadToBio consortium.

STAR-ProBio’s first Focus Group Webinar on Sustainability Assessment Factors for Bio-Based Products took place on January 29, 2018.
The discussion was moderated by Luana Ladu (TU Berlin) and comprised experts with a EU perspective and representatives from various stakeholder groups from Belgium, Germany, Italy, Spain and The Netherlands.
Five questions built the foundation for the discussions:
- Which sustainability parameters/criteria should be considered by a sustainability assessment scheme for bio-based products?
- Which factors should be mandatory in such a scheme and which ones should be voluntary?
- Are particular parameters/criteria needed to assess specific bio-based products/product groups?
- How should the compliance of these parameters be communicated to consumers?
- Which particular needs regarding sustainability assessment parameters/criteria does your specific stakeholder group have?
The key conclusions of the event were summarized as follows:
1 Fossil-based products should be subject to the same sustainability criteria as bio-based products.
2 The only main difference for bio-based products is that the raw material is biomass. Therefore additional criteria regarding the production of biomass could/should be added.
3 Sustainability criteria for biomass for bio-based products should/could be similar to those applying to biomass for energy applications where binding criteria exist.
4 Regarding whether there should be a minimum percentage of bio-based content, different influencing factors have to be considered; in particular technology issues and consumers’ expectations.
5 Environmental criteria are more obvious than social and economic criteria.
6 The origin of biomass is also of importance (as shown by the bioenergy discussion).
7 Criteria that were explicitly referred to included: GHG emissions, bio-based content, and health-related aspects.
The results will enrich the current sources for the preparation of a Delphi survey and also support various other current project activities.
More Focus Group activities on specific stakeholder- and product-related topics will take place within the duration of the project.
