3. WWW.SPIRE2030.EU Concept 3 The technology enables industrial sites to process on- site their dusts economically into products with high economic value. Option to design the demonstrator to be able to host also a thermochemical process involving the fractioned extraction of phosphate and heavy metals from sewage sludge ash at high temperatures under reducing conditions This project idea will adress call tpoic SPIRE 7 -2015 „Recovery technologies for metals and other minerals“ Zn-depleted Fe-rich slag Benefits along value chains: Landfilling is reduced and also process efficiencies and economics of metal recyclers (e.g. secondary cast iron produers can be disburdened from Zn-inputs) and final metals producers are improved. Two high grade secondary raw materials (Zn-Oxide, Fe-slag) are produced, which are used as feed specifically tailored to the process requirements of consequent metal production (in addition, also cement production and construction aggregates are options for the Fe-slag). Comparative advantages of the process are wide range for dust grain size and metals content of input material, absence of pre-treatment requiremenets, no mechanical parts, reaction speed, reduced energy consumption, small scale units for on-site operation.

4. WWW.SPIRE2030.EU Idea Impact - call topic Proof of economic and industrial feasibility: Laboratory pilot plant is operating successfully (Project 1.2 “RecoDust” under the Austrian K1-NET COMET). Scale up to near industrial scale demonstrator with industrial site integration is thus well prepared. In case of inclusion of sewage sludge ash extraction the FP 7 “RecoPhos” will be the starting point. Potential for reducing dependency from imports: For Zinc Europe has an import dependence of 65%. At the same time Zinc present in industrial dusts which are recovered at high cost or largely not at all has a potential to reduce around 5%-points and reduce recycling-cost cost significantly as well environmental impact. Increased Fe-recovery will increase steel making yields and thus Fe-imports. P-content in the sewage sludge produced in Europe could replace roughly up to 20 or 30% of the phosphate imports into the EU. Significant impact on the resource efficiency of industrial sectors: Process efficiency of metal recovery chain is significantly increased and thus resource use. Hitherto landfilled low-concentration metal bearing dusts are rendered processable. Enhanced sustainable industrial processes, shorter time to market and higher production capacity: See above. Recovery costs for Zinc from dusts and P from sewage sludge will fall significantly. Cross-sectorial technology transfer: One basic installation design can support different reaction processes and can thus be applied both to metals recovery and P-recovery. Cross-sectorial character of the idea: Sectors where residuals have their origin (e.g. steel, sewage works) are enabled on-site to beneficiate their residuals. These materials can then be directly used by the existing primary metal producing sectors e.g. (metals, phosphorous). The project aims to bring together residual owners, equipment producers, metal producers, chemical industries (maybe Cement producers) to accelerate value chain optimisation across these sectors. 4

5. WWW.SPIRE2030.EU Idea impact - SPIRE Roadmap 5 „Expected outcomes for the SPIRE stakeholders“ for W2R taken from SPIRE Roadmap page 87f. Relevance to project idea The development projects show that the material losses in the selected existing recycling processes can be reduced by 70%. Not material losses in recycling processes are being addressed, but their chemical and energy efficiency improved. In addition, hitherto unused sources of materials for thise procrsses will be mobilised.. Development of efficient pre-processing technologies for complicated waste streams enable economically viable recovery of selected scarce minor compounds. Adressed. Collection efficiencies for mobile phones and other small electronic appliances improved by 50 % compared with current efficiencies. Not addressed. At least 5 new cross-sectorial waste valorisation concepts developed by 2025. Addressed. By 2020 modelling tools and crosssectorial databases for more holistic and systematic analysis of the viability of recycling opportunities developed. Indirectly addressed, because life cycle evaluation will be part of the project. By 2025 novel integrated modelling concept demonstrated. Not addressed. If feasible project could be linked up to a respective modelling project. By 2025 novel recycling process concepts for at least 5 different (complicated) waste streams demonstrated. Addressed.

6. WWW.SPIRE2030.EU Existing Project Consortium No consortium for the SPIRE-call formed at this stage. Core of the SPIRE consortium will be formed from members of the consortia operating the existing lab- pilots: for RecoDust download “factsheets” under http://www.ffg.at/comet-compentence-centres-excellent- technologies-k1-centres http://www.ffg.at/comet-compentence-centres-excellent- technologies-k1-centres for RecoPhos see http://www.recophos.org/c/mid,1361,Consortium/ http://www.recophos.org/c/mid,1361,Consortium/ 6

7. WWW.SPIRE2030.EU Looking for partners… 1.To provide input materials, owners of residual metal-bearing dusts. P-containing sewage slag owners. 2.To design, build and maintain the demonstrator, industrial equipment manufacturers. 3.To establish the life cycle based evaluation, institutions with respective know-how. Ideally this could be linked to another SPIRE project. 4.To establish integrated road testing of the secondary raw materials produced, metal (and maybe Cement) producers. 5.To control possible effects on possible use of slags as final products, building industry. 6.If feasible, link or cooperation with another SPIRE project devoted to modeling. 7
