Reuse and recyclingKristian Erlandsen2024-01-16T11:23:49+01:00 Reuse and recyclingClimate change and the general lack of resources has created a substantial need for and focus on recycling not least the recycling of construction materials. At Artelia, we can manage the entire project from assessment of used construction materials to the revitalisation of materials in new and sustainable projects. Reuse and recyclingServices and phasesExamplesReuse and recycling We make the best of the resources available The increasing need for recycled construction materials is reflected in the building owner’s requirements. Most building owners now require an assessment of the recycling opportunities in connection to their demolition and renovation projects and, similarly, the possibility for reusing materials in new developments. To live up to these requirements, it is necessary to implement a systemic approach to demolition projects and to properly manage the resources that can be reused. The current legislation and the potential emergence of environmentally dangerous toxins are among the most common challenges to arise in these projects. Our initial step, when taking on new projects, is to take a virtual tour of the building that is to undergo a reconstruction or be demolished. Here, we identify the hidden resources and define what is needed for the materials to regain new life in other buildings. Hereafter, we can manage all the processes in the following project phases. Services and phases Our consultancy divided into project phases Artelia offers consultancy through the entire process, and our services can be divided into project phases depending on your needs. Ressource screenning A preparatory assessment of the potential for recycling of construction materials often including an environmental screening. This allows us to provide clients with an initial estimate of what resources are hidden within the specific building. Resource mapping We scrutinise the building, take samples and describe and categorise the resources identified. In addition, we prepare a technical and financial assessment of the potential for reuse and recycling. This includes a description of the specific use of the materials. Resource plan A detailed plan for the demolition process and management of construction materials. We are capable of managing the complete tender processes and prepare instructions for demounting, storage and transportation of materials. Storage and preparatory processing As a general rule, the materials must be either pre-processed or stored up until use, both of which we can facilitate. During the pre-processing, we can provide the specific guidelines for cleaning, sanding and painting etc. Production of materials Most often, the construction materials will be converted into new innovative construction materials. We will help design and develop the materials. We can monitor the production and oversee the authorities’ approval. The recycling process We provide assistance to the recycling process of both unpolluted and polluted construction materials for new development projects and renovations. We do not only match the suitable resources to the specific projects we also help with: Clarification of laws concerning recycling of construction materials such as BR18 and fire safety regulations Indoor climate assessments in the event that environmentally dangerous substances occur Preparation of SAB and a plan for health and safety (PSS) for the construction materials Preparation of material passports Information regarding the materials’ contributions to achieving certifications such as DGNB, the Eco Swan Label and C2C Examples Examples of recycled materials Tile and timber Isolation of wood fibre and papir, respectively Recycled plastic Lisbjerg Recycling StationLisbjerg’s recycling station is a symbol of the circular economy – turning waste into resources with a focus on increased recycling. The building itself also symbolizes this effort by using recycled materials as primary building blocks in line with the need for more environmentally friendly practices.

With its 78 meters and 20 floors, this will not only be Denmark’s tallest wooden building, but also an architectural achievement and a laboratory for reuse and recycling, which is incorporated into every part of the building. Owner PFA Pension and Kilden & Hindby Architects Lendager A 45% reduction in CO2 emissions using recycled construction materialsUpcycle Studios in Copenhagen is a convincing example of how it is possible to reduce the CO2 emissions considerably by converting construction waste into a reusable resource. LCA and LCC analyses of the housing project show that the reduction of CO2 emissions reaches approximately 45 % over the course of the building’s life span. The building’s structure is made from recycled concrete whereof 1400 tons are cast from long-lasting concrete waste from the construction of Copenhagen Metro. 75% of the windows are recycled from houses in Northern Denmark while excess wood from the timber design company, Dinesen, has been turned into facades, floors and walls.
