AIMPLAS AIMPLAS is developing the ENZPLAST2 project with the support of the Valencian Institute of Business Competitiveness (IVACE). The aim of the project is to develop new, more sustainable processes for producing, recycling and composting plastics.

New Methods for Synthesis of Plastics

Funded by IVACE and co-funded by the European Union (ERDF) through the Spanish Autonomous Community of Valencia ERDF operational program (2014-2020), the ENZPLAST project focused in its first year on new methods for the synthesis of plastics that are safer for human health and more environmentally friendly. In particular, enzymes were used instead of metal catalysts to obtain polyesters.

This provided two benefits:

  • Reducing the toxicity of these metal catalysts
  • Lowering energy consumption during the polymerization process

Microorganisms to Eliminate Odors from Packaging

In the second year of the project, under the name ENZPLAST2, a procedure is being developed to use microorganisms to eliminate odors from dairy packaging. Initial results indicate a reduction in the odor intensity of recycled dairy packaging. In addition, treating polyurethane-type polymers with selected isolated microorganisms has been shown to help degrade these polymers by as much as 70 percent.

Finally, studies have also been carried out in the second year on including polymer-supported enzymes in a molten polymer to improve the biodegradation of different bioplastics under aerobic and anaerobic digestion conditions.
