Construction waste disposal practices: the recycling and recovery of waste

摘要

The rate of recycling and recovery of construction and demolition waste for the year 2020 is set at 70%. Currently in Romania, the waste recovery level is far below the set value, the collected waste is mostly disposed of by storage in landfills, without any other recovery or reuse. This paper presents practices in recycling of waste obtained from the construction of new buildings and demolition of existing buildings, with the potential of recovering large amounts of construction waste as filling material for road infrastructure or for heavy loaded industrial floors as well as possible other applications for using construction waste to substitute natural resources in concrete composition, obtaining material embedding waste with low energy consumption. The presented solutions might lead to an important increase of the recycling and recovery percentages, contributing to the fulfilment of the targeted and recycling, recovery and reuse rate. The viability of the possible applications is demonstrated with practical examples.
