Paper_Sustainable construction with CCPs - an update for Europe -

In Europe, the developments towards carbon neutrality by 2050 with impacts on fossil-fired production but also for construction materials and construction are finding it’s way. For fossil-fired energy and heat production this results in increased production by renewables and respectively discontinuous replacement production by coal power plants, and by this in availability issues for Coal Combustion Products (CCPs). For most member states phase-out dates have been published and some countries already phased-out. Although known and used for decades, especially fly ash is subject of increasing interest for the production of carbon-reduced cement and concrete. The CCP production in coal-fired power plants in Europe still totals to about 75 million tonnes with decreasing tendency. Beside fresh production in power plants, especially fly ash is re-used from stocks and stocks with fly ash and bottom ash are under investigation. Furthermore, imports serve for customer needs. In addition to CCPs also other alternatives serve as raw or construction material having partly only regional significance. The declaration of sustainability factors is a must for future construction, also data base entries are important for planners. The report gives an update on the diverging developments of market needs and options by CCPs.
