About 50% of primary raw materials in the EU are used in the building sector, which is also responsible for about 1/3 of all wastes. Within the construction and demolition wastes (CDW), components like concrete, bricks, tiles and ceramics (CBTC) have high potential to be applied as recycled aggregates and sands. However, until now, recycled materials are mostly down-cycled to be used as filling materials in infrastructure projects. Although the recycling quota of CBTC is more than 70% in DE, BE, FR, NL and LU, less than 4% are re-used for the original purpose: concrete production. The project aims to increase the use of CDWs (mainly CBTC) as secondary raw materials for cement and concrete production in NWE. It is necessary to start a high-quality recycling of CBTC, which then enables the re-use of the materials for concrete precast products (CPP). In addition, the project will show how fines (<2mm) from CDW can be used in cement (CM) manufacturing . The project will thus enable, 10 years after its completion, an increased use of up to 13 million tons/y of CBTC’s in NWE’s CPP and CM. SeRaMCos overall outputs will be (a) Technologies enabling the use of recycled material in cement and concrete production: innovative treatment methods for CDWs and new cement production methods using various sands qualities; (b) Industrially produced cement and CPP from recycled aggregates, which will be comparable to conventional products in costs and quality. The products will be implemented in 3 pilot areas: City of Seraing, BE, City of Saarlouis, DE and Region of Moselle, FR. With the end of the project, the products will be ready for commercialisation in NWE. To increase the demand for and the use of these products, a supply chain and a data base of CPP-producers in NWE will be established. The 3 investments are crucial for market penetration. In parallel, SeRaMCo's long term impacts will be sustained with an EU wide roll-out plan and business model.
