Driven by ambitious recycling targets and a mature collection infrastructure, Europe has built a glass recycling industry that increasingly leans on advanced sorting technology.
Glass recycling rates vary enormously around the world, and few comparisons are as striking as the gap between Europe and the United States. While both regions produce and consume large volumes of glass packaging, the systems built to recover it – and the technology underpinning those systems – have developed very differently.
In much of Europe, decades of public awareness campaigns and well-established bottle bank networks have made glass recycling a deeply ingrained habit. Many European countries report glass collection rates well above those typically seen in the US, where kerbside recycling programmes vary widely from one municipality to the next and glass is, in some areas, excluded from recycling collections altogether due to contamination concerns.
The quality of collected glass matters enormously, because cullet – crushed, sorted glass ready for the furnace – can replace a significant proportion of the raw materials used to make new glass, reducing both energy consumption and emissions at the furnace. The higher the quality and purity of the cullet, the higher the proportion that can be used, which is why colour sorting and contaminant removal are such critical steps in the recycling chain.
This is where investment in sorting technology makes a measurable difference. European recycling facilities have increasingly adopted optical sorting systems that separate glass by colour and remove ceramic, stone and porcelain contaminants – materials that, even in small quantities, can cause defects in new glass. PICVISA's ECOGLASS systems are part of this trend, helping facilities produce furnace-ready cullet at the purity levels that allow it to be used in higher proportions. As the US glass recycling sector looks to improve its own recovery rates, the European experience – combining strong collection infrastructure with advanced sorting technology – offers a clear example of what is achievable.
