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
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.

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
SeRaMCo will showcase the use of secondary aggregate in concrete and the fact that it does not have to be as complicated as sometimes assumed. During the MAKING workshops at TU Delft, the great architectural potential of CDW (Construction and Demolition Waste) in precast concrete is an ongoing topic of investigation. Students look for the added value of CDW in concrete ranging from béton brut, exposed concrete and rammed recycled aggregate, by making objects with added properties. Read More
Eco-friendly, economical, sustainable – First load-bearing prefabricated recycling concrete wall produced (1)Posted on
The German precast producer Beton-Betz has been working for the last 1.5 years in the EU INTERREG project SeRaMCo. The company’s role is mainly to contribute to new raw material compositions and precast elements. Beton-Betz is supported by several universities who research on the characteristics of recycling concrete in their laboratories. During the past months Beton-Betz has gathered practical know-how in using recycled concrete waste. Read More

A new mix design methodology for recycled aggregate concrete by combining experimental and numerical approachesPosted on
An important step towards a sustainable development in the concrete industry and management of construction waste is to use recycled aggregates (RA) as a viable alternative to the natural one. However, how to formulate and optimize the concrete mixture made of recycled aggregates at an acceptable price and quality is still a question mark. The major difficulty is due to the variability of the aggregate properties, and the lack of a robust methodology able to accurately evaluate the mechanical performance of the recycled concrete. Read More
Recycled Aggregates (RA) from Construction and Demolition Waste (CDW) contain natural aggregates, hardened cement paste but also masonry, plaster, etc. Part of these recycled aggregates are hardly suitable for concrete production due to their water absorption (cement paste porosity, clays) and reactivity (sulphate or alkalis release, etc.). RA incorporation in Portland cement raw meal is a possible way to use these recycled aggregates and consequently avoid landfill. Read More
