Construction and Demolition Waste Management - Why did the Eu changed the definition of Backfilling ?

The change in the definition of backfilling in the revised Waste Framework Directive of 2018 reflects the need to address the quality and environmental impact of recovery operations related to construction and demolition waste (C&DW). The original definition, as per Commission Decision 2011/753/EU, described backfilling as a recovery operation where suitable waste is used for reclamation or engineering purposes in excavated areas or landscaping, serving as a substitute for non-waste materials.
