LIFE EXTRUCLEAN - REMOVAL OF HAZARDOUS SUBSTANCES IN POLYETHYLENE PACKAGES USING SUPERCRITICAL CARBON DIOXIDE(SC-CO2) IN RECYCLING PROCESS

LIFE EXTRUCLEAN - REMOVAL OF HAZARDOUS SUBSTANCES IN POLYETHYLENE PACKAGES USING SUPERCRITICAL CARBON DIOXIDE(SC-CO2) IN RECYCLING PROCESS

The project’s main objective is to demonstrate the viability of a new technique for eliminating hazardous substances from waste polyethylene (PE) packaging for solvents or phytosanitary products. The project will use a technology that applies a supercritical carbon dioxide (sc-CO2) in the extrusion phase of the plastic recycling process 

This process is expected to partially, or totally, substitute for two of the three stages involved in conventional treatments, which should reduce the labour requirement and the consumption of energy and water. The recycled material will then be employed in the production of packaging for hazardous substances, closing the life cycle. The project aims to provide a reference for the implementation of new solutions in the plastics recycling industry, leading to more efficient and environmentally-friendly processes, as well as higher quality recycled material.

Expected results: The project will develop a new recycling technology for waste plastic packaging for hazardous substances. If applied in ATECO’s plastic waste management facilities, which uses three washes with a capacity of 18 m3 of water and has an annual output of 1000 tonnes/year, the project expects to achieve:

  • A reduction in water consumption: from 558 m3/year to 279 m3/year;
  • A reduction in chemicals use: from 45 tonnes/year of surfactants, NaOH and wastewater treatment substances, to 15.75 tonnes/year;
  • A reduction in energy consumption: from 15 000 kWh/year to 1500 kWh/year, which equates to a cut of 630kg CO2/year.
