SeRaMCo: Secondary Raw Materials for Concrete Precast Products
The construction sector is the most resource intensive industrial sector in the EU. It uses around 50% of the available primary raw materials, hence exhausting the natural resources, degrading environment and generating high costs to the business operators.
Although there is potential for the use of secondary raw materials from construction and demolition waste (CDW), this is far from becoming mainstream in Europe. For the time being, the sector uses only 4% of the recycled construction and demolition waste (CDW), although CDW represents the largest waste stream in the EU, accounting for 1/3 of the overall European waste.
Against this background, this situation is not dire in the whole of Europe. Some North-Western Europe (NWE) countries, namely Germany, France, Belgium and the Netherlands are leading the way in recycling CDW. Depending on the individual country, these rates range from 70-95%.
However, although waste recycling rates in NWE are impressive, business operators from the construction sector are still faced with challenges in placing their recycled products on the market. This is primarily due to the fact that there is still no niche market for concrete products made from the recycled materials. The lack of a niche market is accompanied by the lack of a clear-cut legislative framework in certain NWE states and inability to make precise cost estimations reflecting both social and economic costs of the production.
To make the most out of the available resources, SeRaMCo aims to replace primary raw materials with the high-quality materials recycled from CDW, e.g. concrete, bricks, tiles and ceramics (CBTC), in production of the cement and concrete products for use in NWE. To attain this goal, the project will:
analyse and improve sorting of CDW, as a precondition for successful recycling;
develop and test new concrete mixes and technologies for the production of concrete precast products (CPPs) made from the recycled CBTC;
establish a market niche for CPPs, leading to the economic advantages for the CPP producers and generating new jobs in the construction sector.
SeRaMCo’s expected outputs are cement and CPPs from up to 100% recycled aggregates, comparable to conventional products both in terms of costs and quality, and ready for commercialization in NWE.
Prior to rolling-out across NWE and Europe as a whole, SeRaMCo will test its end-products in 3 pilot areas, namely City of Seraing (Belgium), City of Saarlouis (Germany) and Region of Moseille (France). Following the testing phase, previously developed business models, supporting the supply chain of the new market niche and establishing ecosystem with stakeholders active in the field, will be put in place.

In September 2018, a first successful trial of the use of recycled aggregates - prepared by TRADECOWALL and sourced from CDW (Construction & Demolition Waste) - took place at the VICAT cement factory in Créchy, France. Read More
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.

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
One of the goals of the SeRaMCo project is to improve the sustainability of the concrete industry. One possible avenue to reach this goal is the use of recycled aggregates obtained from Construction and Demolition Waste (CDW). They are obtained by crushing suitable CDW such as concrete, bricks, tiles, ceramics, natural stones. However, the crushed material still contains unwanted elements such as rebars coming from reinforced concrete, plastics, woods, and paper. Read More
In the scope of SeRaMCo, Tradecowall is in charge of developing technologies for the recycling of mixed construction and demolition waste. Following our tests in 2018, we are proud to announce that we now master the key processes of water clarification and sludge management! Read More
The University of Luxembourg is actively working to design a new mixture for precast elements which involve a total/partial substitution of secondary raw materials. The recycled material is supplied by Contern and is sourced from the crushing of unused drainage pipes. Read More
One of the aims of the SeRaMCo project is the development of concrete mixes for the production of non-structural elements, in particular the production of paving blocks. Furthermore, the Institute for Construction Material Technology of the University Kaiserslautern, as one of the involved partners, tries to develop concrete mixes for rammed concrete. Read More
The focus of the final SeRaMCo conference will be on the results of the project’s 3-years top-notch research, together with the latest information regarding building with concrete made from recycled aggregates and sands. To this end, participants will be introduced to innovative concrete precast products. Furthermore, external high-level speakers and experts in the field from research, business and policy-making have been confirmed who will be giving interesting insights into the topic.
Over a day and a half, this transnational event will focus on the results achieved by the 83 NWE projects funded so far, and how to further support their uptake and impact. The SeRaMCo project will be present with a booth to present the project's results.
Have a look at our event calendar, which is regularly updated with interesting conferences and meetings.
The University of Luxembourg has the pleasure to invite you to the mid-term conference of the European project SeRaMCo: “Secondary Raw Materials for Concrete Precast Products”. Initiated in 2017 with 10 European partners, SeRaMCo aims to replace primary raw materials with the high-quality materials recycled from construction and demolition waste. The mid-term conference will be a great opportunity to show first results of the project SeRaMCo and to discuss the subject with invited expert speakers.
