SCGC and ATCM pilot advanced recycling to convert used XLPE wire insulation into circular naphtha

Recycling challenge

Cross-linked polyethylene (XLPE) is widely used for wire insulation because its covalent crosslinks create a permanent three-dimensional network that resists melting and reprocessing. As a result, more than 2,000 tonnes of degraded or end-of-life XLPE wires are sent to landfill each year with no recovery route.

Collaboration and objective

SCGC and the Trade Association of Thai Cable Manufacturers (ATCM) are collaborating to explore advanced recycling that converts used XLPE insulation into hydrocarbon streams, including circular naphtha, for use as petrochemical feedstock and in recycled plastics. Produced materials are intended to meet virgin-equivalent performance and are supported by ISCC PLUS certification across the supply chain.

Testing and results

SCGC evaluated a range of used wire types: peroxide- and silane-crosslinked XLPE, low- to high-voltage wires, complete multilayer structures (insulation plus jacket) and mixed waste streams. Under tested conditions, the process converted material into circular naphtha without generating solid residue requiring further disposal.

Implications

The approach could enable manufacturers to reclassify crosslinked scrap from disposal cost to a recoverable material stream that serves as feedstock for petrochemical production and high-quality recycled plastics under SCGC GREEN POLYMER™.
