The data published by the European Container Glass Federation shows that the EU28 average collection rate for recycling of glass containers has grown to a rate of 76%. However the stabilizer produced at mechanical-biological treatment (MBT) installations at landfills still contains large amounts of recyclable glass. An industrial-scale study has been undertaken in order to assess the possibility of recovering this glass from the stabilizer. A new pilot installation was built at the MBT plant in Marszów, Poland. Tests were conducted on stabilizer samples produced at the plant (13 samples) and others collected from several MBT plants based in Poland (six samples). Processing the stabilizer on the designed line made it possible to recover on average 68.4 ± 7.0% of the glass contained in it from Marszów samples and 58.4 ± 14.2% in the case of samples acquired from other MBT installations. It is demonstrated that the concentrate quality largely depends on the stabilizer's moisture content. A concentrate with glass content from 98.0% to 99.5% was obtained for samples of low-moisture stabilizers (for 14 out of 19 samples). The product was accepted by glass recycling plants due to its low level of contamination with other materials and its appropriate particle size.
欧洲容器玻璃联合会公布的数据显示，欧盟28国玻璃容器回收的平均回收率已增长至76%。然而，垃圾填埋场的机械生物处理（MBT）设施产生的稳定剂中仍含有大量可回收玻璃。为了评估从稳定剂中回收这种玻璃的可能性，开展了一项工业规模的研究。在波兰马尔舒夫的MBT工厂建造了一个新的试验装置。对该工厂生产的稳定剂样品（13个样品）以及从波兰几家MBT工厂收集的其他样品（6个样品）进行了测试。在设计的生产线上对稳定剂进行处理后，从马尔舒夫样品中平均可回收其中所含玻璃的68.4±7.0%，从其他MBT设施获取的样品中则为58.4±14.2%。结果表明，精矿质量在很大程度上取决于稳定剂的含水量。对于低水分稳定剂样品（19个样品中的14个），获得了玻璃含量在98.0%至99.5%之间的精矿。由于该产品受其他材料的污染程度低且粒度合适，玻璃回收厂接受了该产品。
