Holcim is a Swiss-based global building materials and aggregates company. Founded in 1912, the company expanded into France and then throughout Europe and Middle East during the 1920s. They expanded in the Americas during the 1950s and went public in 1958. The company continued to expand in Latin America and added Asian divisions during the 1970s and 1980s. A series of mergers and buyouts made Holcim one of the two largest cement manufacturers worldwide by 2014, roughly tied with rival Lafarge. In April 2014, the two companies agreed to a US$60 billion "merger of equals". The deal will face regulatory scrutiny and likely will take more than one year to complete.As of 2014, Holcim does business in more than 70 different countries and employs 71,000 people. The company is the market leader in cement production in Australia, Azerbaijan, India, Slovakia, Switzerland, and Latin America. Wikipedia.

The SPIRE Roadmap calls for an industry-focused study of current sustainability assessment approaches across the process industries, with the aim of identifying and promoting a suitable toolkit. Project STYLE is an industry-led consortium representing a broad spread of process industry sectors with numerous products that cross sector boundaries through their value chains. Partner organisations (Britest, ArcelorMittal, Carmeuse, Holcim, RDC Environment, IVL, Solvay, Tata Steel, Utrecht University and Veolia) bring together a wealth of knowledge and experience in the use of tools for sustainability assessment. Active stakeholder engagement/support from public and private sector organisations, national standardisation bodies and industry associations from project inception, will ensure focus and clarity in addressing the challenges identified in the call. Project STYLE has three key objectives, to: 1. Identify best practice in sustainability evaluation, across sectors and through value chains via inventory and classification of established approaches. 2. Test and deliver a practical toolkit for sustainability evaluation of processes and products, spanning multiple sectors and easily usable by non-practitioners of LCA. 3. Determine gaps, through critical assessment and validation, and identify future research needs to improve the toolkit and ensure broad applicability across sectors. Industrial partners in the project will provide the cross-sectoral case study opportunities for testing existing partner tools and selected tools identified through the inventory and classification stages. The research and consultancy partners will ensure that the project methodology is rigorous, sufficiently wide-ranging and that recommendations are validated and consistent with the best world-wide standards. Dissemination of project outputs via and in collaboration with the stakeholder groups will promote uptake and increase the EU knowledge base for sustainability evaluation.

The main objective of the project is to develop solutions to recover the waste heat produced in energetic intensive processes of industrial sectors such as cement, glass, steelmaking and petrochemical and transform it into useful energy. These solutions will be designed after an evaluation of the energetic situation of these four industries and will deal with the development of Waste Heat Recovery Systems (WHRS) based on the Organic Rankine Cycle (ORC) technology. This technology is able to recover and transform the thermal energy of the flue gases of EII into electric power for internal or external use. Furthermore, a WHRS will be developed and tested to recover and transform the thermal energy of the flue gases of EII into mechanical energy for internal use (compressors). In order to reach this objective several challenging innovative aspects will have to be approached by the consortium. It is planned to design and develop a multisectorial direct heat exchanger to transfer heat directly from the flue gases to the organic fluid of the ORC system and to develop new heat conductor and anticorrosive materials to be used in parts of the heat exchanger in contact with the flue gases. These aspects will be completed by the design and modelling of a new integrated monitoring and control system for the addressed sectors. The consortium consists of 8 partners from 4 European countries. They cover several relevant sectors of the energy intensive industry, namely cement, steel, glass and petrochemical sectors. The industrial involvement in the project is significant and the project addresses the implementation of a full demonstration of the WHRS for electrical energy generation in one of the industrial partners (CEMENTI ROSSI) and a semi-validation of the WHRS for air compressors energy supply system at pilot scale.
