Removal of hazardous substances in polyethylene packages using supercritical carbon dioxide
(sc-CO2) in recycling process

About the project

Around 3% of waste generated in the EU27 is hazardous, which represents about 12 kg of hazardous waste per capita (2006 data, EUROSTAT). EU legislation covering hazardous waste requires Members States to comply with certain rules concerning its collection, handling, recycling and treatment.

The conventional method for reducing or eliminating threats from hazardous containers waste involves the triple rinsing and draining of empty containers. Specifically, it involves prerinsing, crushing, washing (with different washing agents, detergents or surfactants) and subsequent rinsing and drying. After drying, the material can then be passed through an ex- trusion line, to produce a recycled material in pellet form
This process requires large amounts of water, cleaning agents, and energy. It also produces large volumes of wastewater. Additionally, the recycled plastic obtained from a conventional recycling process is used in applications with low added value (e.g. pallets), as they generally have inferior mechanical and organoleptic properties.



New recycling technology for waste plastic packaging for hazardous substances, reducing considerably the consumption of water and energY.

Innovative Technique

Demonstrate the viability of a new technique (sc-CO2) for eliminating hazardous substances from waste PE packaging for solvents or phytosanitary products.

Reduce Energy Consumption

Substitute, partially or totally two of the three stages involved in conventional treatments, which should reduce the labour requirement of energy consumption, chemicals and water.

Longer Life Cycle

Use the new recycled PE in the production of packaging for hazardous substances, closing the life cycle.

More Efficient

To a more efficient and environmentally friendly processes as well as a higher quality of recycled materials.

Hazardous Substances

Demonstrate the viability of the elimination of hazardous substances in polyethylene (PE) waste, coming from packages
