“…Recycling efficiencies E F and E C vary for different products and detailed information are given neither in OBD nor in literature [9,22]. Thus, instead of using exact individual efficiencies, the standard value of 75% indicated by Madaster Services B.V. [28] is applied for E F and E C .…”

“…Furthermore, the main category "Other" was eliminated due to lack of relevant data. Due to the study's focus on materials which are well suited for recycling [9], less relevant categories, such as building technology, components of windows, and curtain walls and coatings, were not considered. The analysis thus focuses on the main categories mineral construction materials, metals, plastics and insulation products.…”

“…The main objective of the circular economy is to avoid wasting raw materials and to close material loops by adopting circular strategies, such as reuse, repair, remanufacturing, and recycling of products and their materials [29]. A circular economy in the construction industry is still in its infancy and there is consequently a very high potential for an increased use of recycled materials, increased reuse of resources, and more sustainability [9]. For the transition towards a circular economy, both scale and quality of construction and demolition waste recycling need to be increased in the near future [20].…”

Measuring circularity: evaluation of the circularity of construction products using the ÖKOBAUDAT database

Background Owing to the large amounts of energy, greenhouse gases, and waste that it generates, the construction industry is fundamental to the transition towards a circular economy. Indicators which show the circularity of products—and thus make them comparable with each other—can be used to support the implementation of such an economy. In this article, we have adapted the material circularity indicator of the Ellen MacArthur Foundation in order to analyze the circularity of construction products available in the German environmental database ÖKOBAUDAT. Results The adapted indicator is applied to 89 building products from the categories of insulation materials, plastics, metals, and mineral building materials. More than half of the products receive the lowest score of 0.10, indicating poor implementation of circular strategies in the German construction industry to date. Conclusion Circular material flows are most likely to be employed for metals. However, the overall low circularity scores indicate a big need for better implementing circularity strategies.

“…Especially at the last level-the company level-many implementation issues continue to exist, and the levels of circularity of construction products are still low, while the principle of the "linear economy" dominates [12,13]. The reasons for this are mainly the low proportion of recyclable materials used and the very costly separation of construction waste [14,15]. From the perspective of a construction company, the question arises as to what extent these circular economy practices are economically feasible.…”

The circular economy in the construction industry is still in its infancy. It seems particularly difficult for companies in this sector to make strategic decisions that enable sustainable operations and ensure long-term business success. This article investigates factors such as employee involvement at the operational level that facilitate circular economy practices for companies in the construction industry. For this purpose, we conducted a company survey and analyzed it using a structural equation model. The results show that it is worthwhile for companies to empower their manufacturing employees to take actions independently in order to increase process quality and to reduce setup time, which together lead to better circular economy efficiency.
