The collection and sorting process of recycling glass generates crushed glass (glass fines), which is unsuitable for re-manufacture into glass containers.
Reconophalt contains glass fines – the residue which remains after the high value glass is optically sorted. Glass fines normally end up in landfill as sand. Utilising recycled glass as a sand replacement in making asphalt makes sense because it is dry unlike sand which inherently carries moisture which needs to be dried. The drying requires heat and energy meaning glass is a perfect replacement that lowers greenhouse gases.
