Determining Resource Conservation Potentials in the Recovery of Construction Waste and Formulating Recommendations on Their Use

Source: IOER

Abstract

The utilization of waste materials represents an important contribution to the protection of natural resources. This especially holds true in regard to high-grade recycling, which envisions to use wastes as secondary material and to achieve the closest possible product cycles. The aim of the present study is to explore the medium (year 2020) and long-term (year 2050) expected potentials of high-grade recycling of mineral construction waste. The question answered here especially in regard to concrete as mass construction material concerns the extent to which the recycling loop "from building construction back into building construction" could be realized and what resource conservation potentials this would make accessible. The main subjects under consideration are the aggregates in the concrete used for constructing buildings. To this end, there is an accounting of the mass flow which focuses on juxtaposing the deployable, future amounts of suitable construction waste recyclates with the need for aggregates and the amount of corresponding gravel materials that can be substituted by recycled building rubble.
The study indicates huge regional and temporal disparities in the available amount of and the need for mineral recycled aggregate in the building sector. Hereupon, starting points aiming on strengthening a high-grade recycling in the construction industry are proposed and discussed.
