The European railway industry faces great challenges in need for increased network capacity. Ageing infrastructure assets require efficient and sustainable interventions to maintain and improve current levels of performance. To meet these demands and increase the operational performance of the railway infrastructure assets, innovation is needed to enable a step-change in reliability, availability, maintainability and safety (RAMS) and also to optimise asset capital and LCC. The IN2TRACK3 proposal addresses the topic of “Research into optimised and future railway Infrastructure” of the 2020 Horizon 2020 SHIFT2RIL call. The project is a continuation of IN2TRACK and IN2TRACK2 and aims to further develop and demonstrate research results and innovations developed. IN2TRACK3 will develop physical as well as digital technology and methodology demonstrators for the Track, Switches & Crossings and Bridge & Tunnel assets and the project is aligned to the SHIFT2RAIL overall aims. The project structure is designed around three technical sub-projects aiming at both improving the operational performance of existing infrastructure assets and providing radical new system solutions delivering a step-change in performance, improving methods and repair techniques, improve quality, reduce costs and extend the service life of assets and structures. The project is led by Trafikverket, the Swedish Transport Administration Agency, the consortium consists of 27 expert partners originating from 11 European countries and the partners involved are infrastructure managers, research partners, technology developers and industry partners. IN2TRACK3 will further develop and demonstrate a number of innovative solutions based upon the two previous projects and the work will build upon already ongoing mutually beneficial collaboration, established communication paths and a considerable amount of mutual trust built upon years of collaboration in international project environments.

Each year the EU steel sector generates several million tons of metal and mineral containing residues that are currently largely under-exploited and are often sent to landfills with an enormous waste of resources that could replace virgin materials. ReMFra main objective is the development and validation of highly efficient pyrometallurgic melting and reduction demonstration plant at relevant industrial scale for recovering metals and minerals contained in a wide range of steelmaking residues. The ReMFra process will allow to valorise steelmaking residues, such as filter dust, scale, sludge and slags, to obtain pig iron, iron rich oxides, a highly concentrated zinc oxide and an inert slag. ReMFra comprises two main parts to be developed, improved and tested at industrial scale: Plasma Reactor and RecoDust. The first will be dedicated to recover the coarse residues (scale, sludge, slag), while the second will focus on fine-grained dusts. The project will allow the improvement of iron yield using recovered pig iron instead of new pig iron and replacing the iron ore with the iron rich oxide. The recovery of concentrated ZnO and inert slag as by-products will provide a significant source of income and will contribute to the overall carbon neutrality. To reach the full circularity, the process foresees the use, as reducing agent, of secondary carbon sources (i.e. waste plastics). Energy recovery solutions will also be integrated in the metal recovery process starting from enabling the use of molten pig iron. ReMFra consortium comprises: 5 steelmaking companies, 4 RTOs as technology providers with large experience in steel sector, 1 university and the European Steel Technology Platform. To conclude, ReMFra is expected not only to enable technological advances in the demonstrators involved but will also contribute to the development of new standards, training programmes, adaptation and certification of industrial processes thus facilitating the replication of the project.

The rail freight sector is facing a multitude of challenges such as lack of network capacity and productivity. Manual processes still entail worker’s safety risks. Rail must adopt the emerging digital technologies to meet the customer needs. FP5-TRANS4M-R brings together 71 partners from end-users, large industry, railway undertakings – operators and wagon keepers, SMEs, academia and research, delivering on the rail freight sector’s commitment to increase of the modal split share to 50% by 2030 revoking the causality between economic growth in Europe and pollution as well as congestions, positively impacting Europe’s citizens quality of life. FP5-TRANS4M-R’s overall goal is to establish rail freight as backbone of the lowest emission and most resilient logistics chain in Europe fulfilling the end customer requirements to their full satisfaction. Two technology clusters “Full Digital Freight Train Operation (FDFTO)” and “Seamless Freight Operation” will develop, validate and demonstrate the FP5-TRANS4M-R technologies following an integrated systemic approach across the sector, in a competitive manner - as only then the expected automation benefits can be fully realised. Integrating DAC-enabled solutions at non- arguable interoperability with software defined systems and digital rail services will lead to increased capacity, higher throughput and shorter transportation duration. It will strengthen the cross-border coordination and cooperation between rail infrastructure managers and finally deliver optimised overall management of the rail network. FP5-TRANS4M-R's credo is: seamless, integrated, interoperable, validated and EU-wide authorised solutions, to achieve a single EU rail freight technology framework with strictly managed interfaces for an effective system integration and seamless operation across countries, actors and modes. These objectives set the foundation, frame, and ambition for the project with an impact on the overall transport and logistics sector in EU.

Over the past decade, the steel industry in Europe has been spending a lot of effort in Research and Development of technologies that help in achieving the EU’s CO2 emissions targets and reduce the cost of EU ETS compliance. That has been done through a combination of large scale projects which were part publicly funded with European funding and partly through smaller privately funded research activities. From the initial stages of feasibility studies, several technologies were put forward for further development, one of which is the HIsarna smelting reduction process The objective for the current proposal is to prove the capability of the HIsarna ironmaking technology to achieve at least 35% reduction in CO2 emission intensity, compared to blast furnace operated site based on Best Available Technology Currently Installed. This will be achieved through: -Change operation parameters in order to achieve at least 35% CO2 intensity reduction per tonne of hot rolled coil compared to the conventional blast furnace – BOF route through: >Combined iron ore and scrap operation with a scrap rate of 350kg/thm; >Partially replacing coal injection with sustainable biomass injection (at least 40%); >Minimising coal rate by maximising energy use in the reactor, through balancing the energy between the upper and lower part of the reactor (Using limestone instead of burnt lime as a fluxing agent; >Quantifying potential for energy recovery from hot off-gas by installing boiler test panels; >Making the process ‘CCS ready’ by having process gas suitable for CCS with little or no processing by replacing compressed air and N2 carrier gasses with CO2 and CH4 as carrier gas; -Operation of the HIsarna pilot plant for several months continuously in order to establish process and equipment stability; -Test process conditions and validate for scale up to 0.8 Mtpa plant

The objective of the project PURESCRAP is to increase the use of low-quality scrap grades (post-consumer scrap) by deploying and applying best available technologies to reduce impurities. This is achieved through novel sensor combinations and analysis supported by artificial intelligence. A key part is the connection between scrap sorter and the steel industry which are the consumers of the scrap. This ensures that there is a demand for the enhanced purification and valorisation methods. The steel industry also enables the industrial scale verification of the PURESCRAP methods, where sorted scrap is used for steelmaking in semi-industrial and industrial scale. The shredding process is identified as the most promising method leading to impurity liberation and later removal, for which the site of the Swedish scrap supplier STENA is chosen for demonstration. With a better analysis of the scrap material after the sorting and preparation chain, appropriate material handling can be optimised for desired outputs. During the project, sensor stations will be integrated in the two separate processing chains for heavy (cut) and shredded scrap. The proposed innovation of PURESCRAP has the ambition to go far beyond industrial state-of-the-art to achieve a higher recycling rate of post-consumer scrap (increased share of low-quality scrap over the total scrap input by at least 40% or more) compared to the usual practice for a specific steel quality, whereas realistic grades are e.g., rail steel R260 (1.0623; EN13674) and engineering steel 42CrMo4 (1.7225; DIN EN10083). This clearly contributes to the Strategic Research and Innovation Agenda (SRIA ) of the Clean Steel Partnership, and to the achievement of the European Green Deal goals regarding circular economy as well as to the reduction of CO2 emissions. The outstanding performance of the proposed PURESCRAP sensor stations will be demonstrated through the implementation at industrial scale at a scrap supplier site.
