CO2 uptake of recycled aggregates: a way to reduce the environmental impacts of recycled aggregates concrete

Posted on

Construction is essential to the development of countries, even during a global health crisis. Billions of tons of materials are continuously consumed to satisfy the world’s insatiable demand. However, this trend in materials use leads to a significant depletion of natural resources and will converge towards a tipping point. SeRaMCo aims at increasing the use of recycled aggregates and fines in a real circular economy. This article resumes some of these ways addressed in our previous research article and focuses on the effects of CO2 uptake of recycled aggregates. Read More

Creating load-bearing precast parts through the use of recycled concrete

Posted on

In Germany, recycled concrete (R-concrete) is still being produced only to a small extent for load-bearing components, although normative foundations exist, and ecological incentives are given. Concrete precast plants have not yet adapted their product range to this portfolio. Accordingly, this article provides an overview of the challenges faced by precast plants in the implementation of R-concrete and describes how recycled concrete can make use of loadbearing prefabricated concrete elements.

Environmental Impact Assessment of Concrete Recycling

Posted on

The SeRaMCo project aims to promote the recycling of demolition by-products in new concrete. While the reuse of these aggregates is obviously beneficial to the environment, because it prevents the use of new resources, it is more difficult to compare the CO2 emissions of the recycling process to the quarry extraction process. Hence our role in the SeRaMCo project: to evaluate the environmental impact of concrete recycling with Life Cycle Assessment (LCA). Read More
