Some reused materials are pure and meet the level of pristine raw materials, while others may contain impurities of major or minor importance for their purpose.

For example, we will often be able to supply crushed structural concrete of completely pure quality, while e.g. stabilization materials based on mixtures of crushed concrete and bricks may be contaminated with tar, oil or metal residues or be mixed with e.g. plastic.

Both materials can be reused, but how and for what is very different. You must make sure that the reused materials are used in such a manner that they do not contaminate, and aesthetics and design should be considered as well.

To a large extent, it is all about knowledge.

Therefore, we have implemented continuous batch controls of construction waste where we check the outgoing materials for mixtures and contamination.

Based on this, we prepare detailed material data sheets of most types of reused materials so that the customers get an idea of the content and the components, the risk of contamination, regulatory requirements and recommendations for using the materials. When preparing the content for the material data sheets, we focus on the customers’ priorities and how they want to use the materials.

This increases the customers’ insight and minimizes the risk of contamination and incorrect use. Thus, it also increases the motivation to reuse materials. And based on the traffic on our website, this is very relevant. The pages with material data sheets are some of the most visited pages.

Our organization of a systematic batch control and complete material data sheets with technical, environmental and climate-related features for all products is expected to be finished within the next years. 

Our ambitions

In 2020, 3 percent of the construction waste which we receive are reused as new raw materials. A few percent of the materials are deposited where the rest, i.e. 95 percent, such as crushed materials used as fills and foundations, are utilized.

By 2025, it is our ambition that the figure for reuse has increased to 40 percent. In the years to come, it is our ambition that the figure will increase to over 80 percent.

We expect that it will be possible to reuse more materials directly – such as crushed concrete waste for new concrete. However, we also expect new types of materials to be developed. For example, we are working on a new construction material based on a mixture of bricks and concrete.
