Abstract

In many European countries, the environmental properties of waste-derived aggregates are mostly assessed based on laboratory leaching tests such as the standardised percolation tests CEN/TS/14405, ISO/TS 21268-3, or DIN 19528. These tests are conducted under specified conditions, which are similar yet somewhat different from realistic field conditions. Therefore, this study aimed to investigate the leaching properties of ADR (Advanced Dry Recovery) recovered MSWI BA in the field in order to understand more about its environmental impacts in actual civil engineering structures. Two field scale studies (a lysimeter and a larger interim storage field study) were constructed and the leachate quality was investigated. These results were then complemented with the results of previously conducted laboratory leaching tests using a liquid to solid ratio (L kg−1) comparison. The results demonstrated that the leaching behaviours of many potentially harmful substances, such as chloride, copper and antimony, was similar despite the study scale. In addition, this study illustrated the importance of investigating the leaching properties of waste-derived aggregates on a larger scale, even though the uncertainties in such studies may not be easily controlled.
