Programme Operator







DESCRIPTION: This task coordinated by LNEC, induces overall management of the project, general partnership policies, arbitration policies, information exchange plan and dissemination policy, discussion of the obtained results and encountered problems, control of the planning and of the deliverables, overall technical coordination, and preparation of meetings. T1 is coordinated by LNEC and ensures good communication between partners and the project leader. The internal communication process plays a vital role to ensure the necessary synergy and teamwork. This task is interconnected with all tasks.
OUTPUT: Financial and progress report (R1).

DESCRIPTION: The main purpose of this task is to gather information on the European and international experiences, concerning the use of demolition and/or renovation pre-audits in buildings, with particular emphasis on the inventory of materials, presence of hazardous substances in the construction sector and competence of auditors. T2 is coordinated by LNEC. This task is essential to promote the development of T3 and T4. Along with literature review, privileged contacts with experts from Iceland, Liechtenstein and Norway will allow sharing their practices about the CLOSER project and strengthening bilateral relations. Throughout the project, continuous update of T2 will occur.
OUTPUT: Report with conceptual framework review (R2).
DESCRIPTION: T3 aims to understand the stakeholder’s opinion regarding the integration of pre-demolition and/or renovation audits as a tool leading to safer materials with improved quality that enables the higher incorporation of recycled materials as raw materials in the construction sector. The T3 task is coordinated by IMPIC and will be implemented a stakeholder questionnaire. Association of T3 and T2 results, facilitates the development of subsequent tasks and establishment of national implementation scenarios for the audits.
OUTPUT: Report with stakeholder’s survey (R3).
DESCRIPTION: The objective of T4 is to develop the national guide for pre-demolition and/or renovation audits. The task is coordinated by LNEC. In T4 the recommendation for the building pre-demolition and/or renovation audits are developed, being indicated: i) the conditions under which they are applied; ii) the materials type inventory and the way results are presented; iii) the presentation of information on the recovery of inventoried materials.
OUTPUT: Portuguese guide to pre-audit on demolition and/or renovation of buildings (R4).
DESCRIPTION: A real pre-audit for a selective demolition or renovation of a building, conducted in task T5, would validate the guide orientations developed in T4, identification of strengths and weaknesses can lead to adjustments on the guide. LNEC ensures the coordination of T5.
OUTPUT: Report with SWOT analysis (R5).
DESCRIPTION: The purpose of T6 is to outline how to align all activities developed in T4 with the policies related with CDW management. This task will be coordinated by APA and may incorporate additional stakeholder consultation. In T6 the necessary policies will be defined for the implementation of the guide at national level, taking care to unify this instrument with existing ones aiming at the proper management of the CDW in Portugal.
OUTPUT: Report with implementation policies definition (R6)
DESCRIPTION: T7 will be conducted from the beginning of the project towards scientific community, stakeholders, students, and other citizens. Furthermore, knowledge transfer to scientific and social community will be ensured. The task T7 leader will be LNEC. A final conference will be organized by LNEC with other participants support, to share knowledge amongst technical and scientific community.
OUTPUT: Organization of a Final Conference and other events for guide dissemination (R7).

Reduction of the hazardous substance levels in CDW that will be valued with recycling, with a consequent reduction of the environmental impacts associated with the disposal of contaminated CDW and improvement of working conditions for waste managers as they process safer materials (decrease up to 50% of hazardous substances in CDW stream); ii) increased production of homogeneous raw materials from CDW over time, which will result in greater confidence in the quality of recycled materials (decrease up to 30% of mixed CDW); iii) definition of final application for raw materials obtained from CDW, which allows a high recognition of the intrinsic value of these materials; iv) increased availability of information related to the expected recovery and recycling of CDW, which boosts the performance of stakeholders in the demolition and/or rehabilitation process; v) increase the incorporation rate of materials from CDW in buildings (increase up to 20% the contribution of recycled aggregates in aggregates demand). This contribution highlights the increase of confidence in recycled materials and of the use of secondary materials.

The development of CLOSER is in line with the objectives stated in the Environmental Programme. Indeed, CLOSER addresses the management of Construction and Demolition Waste (CDW) that is a priority in specific waste flows, to make a true transition to circular economy. In Portugal, about 2.5 million tons of CDW were generated in 2018. CDW comprises different materials but minerals represent the higher percentage of this flow. These minerals can be used in construction works when they comply with the requirements specified in product standards and in this way, the construction sector contributes to the circular economy. In Portugal, although the preparation of materials from CDW for being reused or recycled already surpass the 70% target of the Waste Framework Directive (2008/98/EC). It is known that the largest share corresponds to mixed minerals that are more difficult to be reintroduced in the market. This fact highlights the need to work more to recover the different materials by itself, i.e. better sorted. In this context, it is expected that the objectives of CLOSER development and implementation of preliminary audits, will have a high impact in the valorisation process. It is anticipated that the reuse of materials will increase as well as recycling allowing increased incorporation of materials from CDW in construction works, namely in buildings. Another problem that CDW faces is the contamination with hazardous substances that hinders the reuse, recycling, and recovery of materials. Contaminated materials do not contribute to circular economy because materials cycle does not close. On the contrary, it contributes to keep a linear economy because CDW will not lose the status of waste. The use of pre-demolition audits can effectively be an answer to solve the contamination. Creation of favourable conditions to reduce the content of contaminants could be achieved in the pre-demolition audits through inspection to the existent hazardous substances. The success of this solution depends on the experience of the auditors and it is therefore necessary to invest on their training. Definition of guidelines for the preliminary audits, suitable for the Portuguese case, are needed, at least, to improve the content of mixed CDW and reduce contamination, while contributing to the circular economy.
