Glasstec, the industry's flagship trade fair, increasingly reflects a sector under pressure to do more with less energy and fewer raw materials – a pressure that technology is helping to address.
The glass industry sits at an interesting intersection: it's both a major energy consumer, due to the high temperatures required to melt raw materials, and a producer of one of the most genuinely recyclable materials available. Events like Glasstec increasingly focus on how to address the first while capitalising on the second.
Glass furnaces are energy-intensive by nature, and rising energy costs have sharpened the industry's focus on efficiency. One of the most effective ways to reduce the energy needed per tonne of glass produced is to increase the proportion of recycled cullet in the furnace feed – cullet melts at a lower temperature than virgin raw materials, directly reducing energy consumption.
Alongside energy efficiency, the industry is also looking at the raw material side of the equation – sourcing sand and other inputs more sustainably, and increasing the use of recycled content wherever furnace chemistry and product specifications allow. For container glass in particular, recycled cullet is increasingly treated not as a supplementary input but as a core raw material.
The amount of cullet that can go back into the furnace depends directly on its quality – colour purity and freedom from contaminants like ceramics and stones are essential, since these can cause defects or even damage to the furnace itself. PICVISA's ECOGLASS optical separators are designed to deliver this quality, sorting glass by colour and removing contaminants so that recycling facilities can supply furnace-ready cullet at the volumes the glass sector increasingly needs as it works towards its efficiency and sustainability goals.
