The use of alternative resources has a long tradition in the Austrian Cement Industry. The success story originally started with the processing of alternative main constituents for cement production. The recent trend reaches out further for the substitution of natural raw materials for the clinker production. For every ton of cement, almost 500 kg of alternative resources have been reused.

The integration of the steel sector into the electricity generation cycle is an example of collaboration between companies from different sectors significantly minimising the environmental impact of their facilities. This integration allows the steel production gases produced by the industrial processes of steel plants to be transferred to an electric company for use as additional fuel.
Cement recarbonation refers to the process where part of the CO2 emitted during the cement production is re-absorbed by concrete in use through carbonation.
Laura Cutaia, researcher at ENEA is an Environmental Engineer (1996) with a PhD in raw materials engineering (2002). Her main research topics are:

Laura Cutaia is the Responsible of Laboratory for Valorization of Resources at ENEA , where she is working on circular economy and resource efficiency, industrial ecology and symbiosis, LCA, environmental certification schemes, REACH regulation and sustainable industrial areas (more information).
Laura Cutaia is also the President of SUN - Symbiosis Users Network (Italian network for industrial symbiosis) and the President of UNI CT 057 on Circular Economy that is working with ISO TC 323 on circular economy. UNI is the Italian competent body for standardization.
As an adviser for environmental and climate policy, Leon de Graaf particularly follows policies related to the circular economy, trade and climate, low-emission mobility, implementation of the Paris climate agreement (COP21) and the European emission trading system (EU ETS). He is also deputy manager of BusinessEurope's corporate Advisory and Support Group (ASGroup). Prior to joining BusinessEurope, Leon worked at the research consultancy Ecorys, focusing on renewable energy and international development issues, at DG COMP on energy and environmental subsidies in Europe, and at the Dutch Environmental Assessment Agency (PBL) on indirect ETS costs for energy-intensive industries. Leon has a MSc in environmental economics and climate change from the London School of Economics, and a BSc in business economics from the University of Groningen.
The following publication provides an overview of why the cement and concrete industry is central to the circular economy and what can be done to leverage the opportunities.
The most used resources in the building sector, such as sand and metals, are non-renewable resources. Extracted, transported and processed in ever-increasing quantities, at ever-higher energy costs and with consequences which are far from negligible for the environment, their use does not fit with a sustainable logic. Thinking in terms of circular economy prompts us to take another look at these linear and consuming models, at both the level of materials for building, energy, land, and that of waste management.
The cement industry and LafargeHolcim under the Geocycle brand, have developed strong expertise in coprocessing. This latter refers to the simultaneous recovery of energy and the recycling of mineral materials within one single industrial process: cement manufacturing. This waste treatment solution allows 100% of the material input to be recovered or recycled in the production process.
Cement and Environment Labour Foundation (CEMA Foundation) was created by Oficemen (Spanish Cement Association) and the two largest trade unions operating in the Spanish cement industry, CCOO de Construcción y Servicios and UGT-FICA, Federación de Industria, Construcción y Agro.
Covestro has developed an innovative technology that allows using CO2 as raw material for the production of chemical building blocks for high-quality plastics.
Circular Glasgow, hosted by Glasgow Chamber of Commerce, will connect with companies across the city helping them to open up new revenue streams, increase competitive advantage and realise financial savings using a range of practical tools.
The functional economy in the chemical industry: 8 case studies demonstrate efficiency and sustainability
Take Back Chemicals is innovating by proposing a 'functional economy' business model in the use of chemicals. Traditional business models are based on sales per volume, whereas TBC uses "chemical leasing" and regeneration process for greater efficiency and sustainability.
The report is based on the study of 3 cases in Belgium and 5 cases in the Netherlands with leading chemical industries.
The GtoG project has put in place an integrated approach to construction and demolition waste by holistic management, starting from the major refurbishment/demolition sites to the reincorporation of the recycled gypsum in the manufacturing process via the processing of gypsum waste as a secondary raw material
