External Thermal Insulation Composite Systems (ETICS), mainly comprised of expanded polystyrene (EPS) as the insulating material, have been used to insulate facades of buildings for the past few decades. In Europe, waste from ETICS deconstruction is currently disposed of in waste incineration facilities or landfills. Although the current quantities of ETICS waste are small, disposal of the increasing quantities of waste is posing a problem in some countries. New recycling strategies, such as the physico-chemical recycling of EPS or reutilisation of material and energy of all ETICS components in cement plants, offer the possibility of a circular economy for ETICS waste in the future. However, this would require a waste management chain from the construction site to the utilisation plant with appropriate waste treatment. To assess this concept further, this study documented dismantling efforts at different construction sites and conducted large-scale trials for ETICS waste treatment. The results of this study will allow the selection of suitable processing units and will be applied in a model developed by the IWARU Institute to determine economically and ecologically advantageous waste management routes that can be used to handle ETICS waste in the future.

未来将使用扩展的聚苯乙烯对解构的外部隔热复合系统进行废物管理。

在过去的几十年中，主要由膨胀聚苯乙烯（EPS）作为绝缘材料组成的外部绝热复合系统（ETICS）已用于对建筑物的外墙进行绝热。在欧洲，来自ETICS解构的废物目前正在废物焚化设施或垃圾掩埋场处置。尽管目前的ETICS废物数量很少，但是在一些国家，如何处置越来越多的废物却是一个难题。新的回收策略，例如EPS的物理化学回收或水泥厂中所有ETICS组件的材料和能量的再利用，为将来ETICS废物的循环经济提供了可能性。但是，这需要从施工现场到利用厂的废物管理链，并进行适当的废物处理。为了进一步评估该概念，本研究记录了在不同建筑工地的拆除工作，并进行了ETICS废物处理的大规模试验。这项研究的结果将允许选择合适的处理单元，并将其用于IWARU研究所开发的模型中，以确定可用于将来处理ETICS废物的经济和生态上有利的废物管理路线。
