At the site of the imposing Belem Cultural Center in Lisboa, we had our first review meeting with the ReCreate project advisor from the European Commission.

At the meeting, each work package leader had the opportunity to present their project achievements made in the past year and a half and to receive feedback from our project advisor Susaná Xara and Elena Granados Menéndez – the external expert architect assigned to the meeting.

Also, the ReCreate review meeting participants had the privilege to see the Terra exhibition at the Lisbon Architectural Triennale 2022, which, in their own words, looks into communities throughout the world that embrace our common home, planet Earth and how do resource depletion, socio-economic inequalities, and climate alter-actions intertwine at different scales. The exhibition is a call to action inspired by shared local insights from around the globe with the potential to transform the current fragmented linear system of cities-as-machines into a circular holistic model of cities-as-organisms.

We were proud to see that the ReCreate project was also part of the exhibition, which was presented to the consortium, as well as the wider architectural community by our own Erik Stenberg.

At the end, we managed to meet each other in person, which also granted us a greater opportunity to increase coordination and create stronger connections.

At the end of the summer, members of the German ReCreate cluster met with members of the Dutch cluster for a transnational technical exchange at a deconstruction site in the small town of Weißenfels near Leipzig in Germany. In consultation with the BTU project manager Angelika Mettke and the German industry project partner Dietmar Gottschling of ECOSOIL, the meeting was prepared on-site to show how partial dismantling is carried out under practical conditions.

The dismantling process was observed by Viktoria Arnold (BTU), Thijs Lambrects, Hamidullah Attaullah (both TU/e) as well as an employee of the office of Patrick Teuffel (head of WP5) at the location site, Hardenbergstr. 39-42. The demonstration allowed them the ability to gain an insight into the dismantling process directly on site.

Considering the process, the partial deconstruction comprised the top two floors of the 5-story prefabricated building of the “P-Halle” type, which was constructed from the same range of prefab elements as the donor building for the ReCreate German pilot project at Otto-Nuschke-Str. 9-14 in Hohenmölsen. Accordingly, the same range of slabs and panels had to be dismantled and the same connections opened. That resulted in 30 dismantled floor slabs which required transport from Weißenfels to Hohenmölsen, where the temporary storage site is located.

The dismantled floor slabs are planned to be (re)used later on the same site in the planned pilot project, the construction of a youth center. Concerning the remaining dismantled concrete elements, they had to be handled with more caution because of potential causes of material composition. By that means, they first had to undergo the process of pre-shredding at the dismantling construction site and then sent to a recycling plant for material processing.

Check out the pictures of the site below of the dismantling process at the deconstruction site:

The project consortium at the first ReCreate pilot

From the 20^th to the 22^nd of June 2022, the ReCreate project partners joined forces during the 1^st project in-person meeting. The meeting was organised by the Swedish country cluster and was held in Helsingborg, Sweden. During the meeting, the participants had the chance, for the first time after 1 full year of project progress, to meet each other in person while a fruitful and successful meeting was held. All partners have made tremendous progress in developing their country cluster projects where they have described future planned activities on dismantling, storing, and reusing building materials in the construction of foreseen projects.

During the ReCreate meeting, all participants visited the first ReCreate pilot, which is an exhibition building built of 99% reused material in the residential area Drottninghög. The Swedish contributors, KTH, Helsingborgshem and Strängbetong have presented their first results and practical examples of how building materials can be reused.

The pilot is made of 99% reused material (by weight) and the carbon footprint is 92% lower when compared with the same building built with new material after today’s standards. In addition, the building is designed for disassembly, i.e., built in such a way that it can be dismantled and the elements reused in another context. For example, all-metal couplings between the elements are made to be easily disassembled.

The consortium meeting was executed with success and a plethora of viable comments and experiences stemming from each respective day of work. Moreover, as ReCreate keeps developing and the pilot projects are being executed, with the Swedish pilot as the best example, ReCreate project is being successful in exploring and harnessing the untapped potential of the existing markets for deconstruction and reuse of concrete elements without damaging them. The novel knowledge stemming from ReCreate will be disseminated by publishing joint public-private open access publications in high-impact international journals; by presenting the work in industry congresses and scientific conferences; and by turning it into open access e-learning content usable for educating and training a new generation of experts and employees with improved competencies in reuse.

Additionally, the mayor of the small-town Mr. Haugk and the chairman of WoBau Hohenmölsen GmbH (owner of the potential donor building) Mr. Luckanus also attended the meeting. After a discussion in the town hall on the possible realization of a (re)construction project with the used concrete elements and on the organization of the deconstruction itself, a possible building site (see photo 2) and the deconstruction object (donor building) in Otto-Nuschke-Str. were visited. On April 19, the gutting of the upper two floors of the residential building will begin and the scaffolding will be erected. From May 2 onwards, the partial deconstruction will be carried out by the company Ecosoil GmbH.

The BTU research team has begun to examine the condition of selected concrete elements intended for reuse in the installed position. In addition to geometric construction surveys, concrete compressive strength measurements were carried out using rebound hammers (see photo 3). The purpose of this is to evaluate the structural condition of the concrete elements, which are about 40 years old, so they’ll be able to make a statement on their reuse within the scope of the suitability test. The technical measurement investigations will be continued in April along with the involvement of students and finally, the concrete elements suitable for reuse will be marked.

Tampere University researchers from WP 7 in Finland visited KTH and the Swedish country cluster in Stockholm in October 2021

Two researchers, Linnea Harala and Lauri Alkki, from Tampere University Work Package 7 in Finland visited KTH and the Swedish country cluster in Stockholm in October 2021. The research of Work Package 7 focuses on the business aspects within ReCreate and the first research deliverable focuses on mapping the local ecosystems of concrete element reuse. The examination of these ecosystems was initiated in summer 2021 within the Finnish Country Cluster by research interviews and ethnographic follow-up. After we had gained a basic overview of the actors, their linkages and ecosystem structures within the Finnish country cluster, we expanded our ecosystem research activities to the Swedish country cluster.

During the research visit to Stockholm, Linnea and Lauri were warmly welcomed to KTH by the Swedish country cluster. This first research visit included formal and informal activities facilitating to get to know each other during meetings, campus tours and delicious lunches. The main research activities included research interviews with the key ecosystem actors and ethnographic follow-up on a reference project site visit and during the Swedish country cluster meeting. However, in addition to these research activities, networking and exchanging knowledge between the country clusters was also of great importance for the collaboration between the Finnish and Swedish country clusters.

ReCreate’s first cross-country cluster research visit exceeded our expectations and laid the groundwork for international future research collaboration within ReCreate. International collaboration was soon initiated as at the beginning of 2022 researchers from the Finnish country cluster started a joint research publication project together with researchers from the Swedish country cluster. This article aims to create an understanding of the concrete element reuse ecosystems in Finland and Sweden. All in all, this research visit was a great way to initiate cross-country cluster collaboration within ReCreate, exchange ideas and knowledge and ultimately improve ReCreate’s influence to maximize impact.
