In BioCleanPaint we work with activities to reduce the climate impact of industrial surface treatment processes by investigating the possibility by
1) Replacing fossil-based solvents with solvents from renewable raw materials.
2) Increasing the proportion of recycled solvents in the process by testing different regeneration methods.
Most paint shops use cleaning liquids based on mixes of solvents for cleaning paint application and paint distribution systems.
Most solvents are produced from fossil based raw materials, such as xylene and ethylbensen. The content of aromatic hydrocarbons is also high. By switching to cleaning liquids made from renewable raw materials, the climate impact can be reduced and the working environment improved while the volumes of solvents sent for combustion are reduced.
In this project, the climate impact will be evaluated using life cycle assessment, LCA. A software in the form of a formulation tool based on Hansen's solubility parameters was previously developed by RISE and will be used to identify alternative solvents with similar solubility properties as those used today.
The project will also investigate the possibility to increase the amount of recycled solvent in the process and reducing the climate impact through to reduced use of solvents.
