Innovative Circular Economy Based solutions demonstrating the Efficient recovery of valuable material Resources from the Generation of representative End-of-Life building materials

Periodic Reporting for period 1 - ICEBERG (Innovative Circular Economy Based solutions demonstrating the Efficient recovery of valuable material Resources from the Generation of representative End-of-Life building materials)

Reporting period: 2020-05-01 to 2021-10-31

EU28 generates around 350 Mt/year of construction, renovation and demolition waste (C&DW), excluding excavation wastes.The ICEBERG project proposes integral recovery solutions for End-of-life Building Materials (EBM) overcoming the main barriers hindering the Circular Economy (CE) in buildings throughout the whole building value chain. Under this context:
The main objective in ICEBERG is to develop and demonstrate novel cost-effective circular smart solutions for an upgraded recovery of secondary building raw materials along the entire circular value chain: from EBM to new building products prepared for circularity, resource-efficiency and containing 30wt% to 100wt% of high-purity (>92%) recycled content. This will be undertaken through 6 pilot circular case studies, covering building materials accounting for more than 85% by weight of the European built environment. ICEBERG will also contribute to raising building circularity awareness among the stakeholder communities (local authorities, professionals, students and final building users).

ICEBERG will be clustered into 3 groups of Work Packages tackling the following activities:
1) Optimization of tools, technologies and products at pre-industrial scale (WP1, 2 & 3): The 3 first WP aims to develop distinctive solutions to foster higher levels of recovery of raw materials from EBM and their incorporation in high added value applications suitable for marketing. The proposed solution will be developed as follow,: a) new Smart tools for refurbishment/demolition planning and digital traceability to facilitate the traceability of the materials from the pre-demolition stage, guided by a highly cost-effective BIM for Demolition Waste (BIM4DW) tool, to the new building products and new buildings tracking via a centralized data base (Cloud Traceability Platform - CTP) and the novel Identification and Authentication Toolkit (IAT), providing identification (based on RFID, QR-codes, tags, etc.) and authentication (digital fingerprint through portable readers). The resulting new digital EBM traceability service will deliver more accurate identification and quantification of EBM, harmonized inventories of waste materials, highest efficient EBM management plans based on economic, timing, health and safety, quality and environmental criteria, authentication of EBM, public data to RMIS and connection among the involved stakeholders (including Blockchain issues). b) Innovative advanced technologies for the production and quality assessment of highly pure RBM. ICEBERG will upgrade the performance of 11 sorting, purification, processing and quality assessment systems through novel strategies that include: optimization of components; higher levels of machine-learning; automation and flexibility; transportability; or redesigning towards leaner processes. Equipment to simulate representative production rates will be developed, tested and refined before the large-scale demonstrations. c) Innovative circular building products with high grade RBM produced by the evolved technologies. Up to 5 intermediate and 8 finished building products will be developed. A prototype design evaluation framework, with enhanced potential for future EBM circularity, will be developed. Then, ICEBERG families of building products will be optimized and pre-industrially prototyped. Design guidelines and practical catalogues for circular building will be also generated.
2) Demonstration of the integrated circular ICEBERG solutions under real operating conditions: The performance of the aforementioned solutions will be demonstrated through 6 representative circular case studies (CCS) aligned with predominant building practices across Europe. ICEBERG building products will include and combine structural elements, envelope, interior walling and flooring, accounting for more than 85% by weight of the built environment. Circular design for greater circularity of building products, as well as the products that will be installed in new and refurbished buildings within the 6 CCS, will be considered as a common activity and validated by means of LCA/LCC/health performance.
3) Preparation for market uptake: Requirements and enablers for new policies, assessment of social attitudes towards circularity of building products to consider the stakeholders perception in market or business strategies by implementing regional Ecobarometers and creation of new standards recommendations and ETA documents (for BIM, building materials and products, processes and CE) will constitute non-technical activities, contributing to effective decision making on the most viable RBM and their potential market uptake. Management of the IPR, business plans and models, international replication assessment (through workshops in the framework of ELAN [Latin America] and Youhong [China] networks) and worldwide business opportunities and dissemination and communication activities, including clustering with other H2020 funded projects on CE will be covered too.
P1: Smart upgraded tools improving the cost-effectiveness, reliability and performance of both the EBM management and traceability.
Tools related to P1 "Smart tools" funtional versions have already been developed and they will be integrated and validated at the beginning of 2022.

P2: Cost-effective sorting, refining and processing advanced technologies. The fundamental knowledge and operational principles of such technologies were generated and validated in previous research projects reaching TRL4 and 5. ICEBERG will mostly shift towards TRL7 by upscaling pre-industrial prototype sorting, processing and quality assessment systems guaranteeing representative production rates (t/hour), incorporating higher efficiency and cost-effectiveness when comparing to the current lab-scale pilot plants;
P3: New cost-effective building products designed for easy disassembly and replacing virgin raw materials by (30-100 wt%) of high-purity RBM. The starting TRL will range from 4 to 6 in function of the type of the target product. Specific adjustments will be initially required at lab scale for the optimization of formulations with higher levels of RBM and then industrial prototypes will be produced at representative manufacturing lines (TRL7), as well as installed in new and refurbished buildings.
Circular design of ICEBERG products has been completed. At the end of the first reporting period, P2 Sorting and Recycling Technologies and P3 Circular Products are in progress and 2 intermediate public deliverables have been reported.
ICEBERG technical innovations obtained from the previously described activities will be developed and upscaled during the first half of the project (2 years). Later the solutions will be demonstrated and validated in 6 large case studies and their environmental and economic impacts will be assessed.
ICEBERG CTP will specifically feed public data on circular building resources into RMIS.
ICEBERG will engage with EBM supply chain stakeholders to formulate design guidelines and policy recommendations for circularity of buildings and components preparing for a transition to a viable and informed deconstruction.
14 scientific publications and 4 patents are expected.
