Safety and toxicity assessments and methodology



In the penultimate episode of the five-piece webinar series of the CBE JU funded research project PERFECOAT the experts will give insights about assessments and used methodology in regards to safety and sustainability of the developed bio-based compounds for sustainable paints and coatings.

When developing novel bio-based solutions, safety and sustainability of bio-based paint and coating products for users and environment mark a top priority. Within the last three years, the partners involved in the EU-funded PERFECOAT project successfully generated and examined a broad variety bio-based paint and coating ingredients. These include a selection of binders made from, e.g., modified alginates (SINTEF), xanthan (Technical University Munich), and xylan (Celignis) derived from different biomass resources like agricultural residues, e.g., poplar wood, beech wood, wheat straw, and late cut grass. Furthermore, the team developed different formulations for red pigments and dyes as well as other colours (e.g., green and purple) produced from yeast and fungi. To allow for the modification of specific properties like self-healing surfaces and fire resistance, fillers and functional nano materials were developed from microbial biomass. 

All these ingredients were tested with regard to their performance, requirements and properties in formulations of three specific use-cases: 

– high-volume UV-curable clear coatings,
– waterborne trim paints for DIY, and
– waterborne wall paints.

All materials developed in PERFECOAT need to meet highest safety and sustainability standards for users and environment. The project will therefore quantitatively demonstrate the sustainability improvements achieved with bio-based solutions compared to conventional fossil-based paints and coatings. This was done by establishing a framework for safety assessment (chemical leaching and skin sensitisation testing), life cycle assessment (LCA), life cycle costing (LCC), and potential social impacts of the developed products and processes. The social study started with identifying potential social impacts and factors that can influence social acceptance (including socio-political acceptance, market acceptance and community acceptance) through literature review and stakeholder interviews. The next steps include finalising the social impact assessment. 

The webinar will provide an overview of applied frameworks, methodologies, and key highlights.
