Gypsum is widely used in the construction sector, and its worldwide consumption has been increasing for several decades. Depending on the lifetime of the used gypsum products, an increase of gypsum in construction and demolition waste follows. Especially against the background of a circular economy, the recycling of waste gypsum is of growing importance. However, the use of recycled gypsum only makes sense if it is environmentally friendly. Therefore, an evaluation of the environmental impacts of industrial-scale processing for the recycling of post-consumer gypsum waste was conducted. The evaluation was performed with an established life cycle assessment software. Original data provided by the industry and complementary data from a database for life cycle assessments were used for the calculations. Two scenarios for recycled gypsum with different transportation distances were calculated. These results were compared with the results of the environmental evaluation of gypsum derived from coal-fired power plants (FGD gypsum) and natural gypsum. The results showed that the utilization of recycled gypsum can be environmentally advantageous compared to the use of natural gypsum or FGD gypsum, especially in the impact categories of land transformation and resource consumption (abiotic depletion potential). For most environmental impact categories, the specific transportation distances have a strong influence.

石膏石膏板回收的环境评价

石膏广泛用于建筑领域,数十年来其全球消费量一直在增长。根据使用过的石膏产品的寿命,建筑和拆除废物中石膏的增加随之而来。特别是在循环经济的背景下,废石膏的回收变得越来越重要。但是,只有在环保的情况下,才可以使用再生石膏。因此,对工业规模处理对消费后石膏废料的回收利用的环境影响进行了评估。使用已建立的生命周期评估软件进行评估。计算使用了行业提供的原始数据以及用于生命周期评估的数据库补充数据。计算了两种不同运输距离的再生石膏的情景。将这些结果与燃煤电厂石膏(FGD石膏)和天然石膏的环境评价结​​果进行了比较。结果表明,与使用天然石膏或烟气脱硫石膏相比,再生石膏的使用在环境方面具有优势,特别是在土地转化和资源消耗(非生物耗竭潜力)的影响类别中。对于大多数环境影响类别,特定的运输距离会产生很大的影响。结果表明,与使用天然石膏或烟气脱硫石膏相比,再生石膏的使用在环境方面具有优势,特别是在土地转化和资源消耗(非生物耗竭潜力)的影响类别中。对于大多数环境影响类别,特定的运输距离会产生很大的影响。结果表明,与使用天然石膏或烟气脱硫石膏相比,再生石膏的使用在环境方面具有优势,特别是在土地转化和资源消耗(非生物耗竭潜力)的影响类别中。对于大多数环境影响类别,特定的运输距离会产生很大的影响。
