Act reliably
Our Annual Report
At Vonovia, we attach great importance to the responsible and resource-efficient use of natural resources to achieve our sustainability goals. Our vision is to foster a circular economy throughout the entire value chain and minimise the use of primary raw materials. A major lever is extending the lifespan of buildings through long-term modernisation and creating extra living space by adding new floors to existing buildings. These measures are substantially more resource-efficient than new construction, as existing structures are utilized and frequently expanded with timber frame methods. Materials as well as the improved reusability and recyclability of building materials. Our goal is to further establish a closed material cycle in the building sector and to continuously increase the share of renewable and recycled raw materials. In addition, we promote the use of circular materials and improve the reusability and recyclability of building materials. Our goal is to establish a closed-loop material cycle in the building sector and continuously raise the proportion of renewable and recycled raw materials. Effective waste separation and recycling are integral elements of our waste management strategy and drive sustainable value creation in our neighborhoods.
As a guideline for the modernization and further development of our existing building stock, we have developed a product manual in which products for the key trades are defined. The inclusion of new products is decided by a cross-functional committee. In addition to quality, price, and technical standards, sustainability is a key selection criterion. In this way, we take into account the high material value of our buildings and reduce the use of primary materials as well as energy and resource consumption.
In addition, we increasingly consider aspects of the circular economy across the entire lifecycle of buildings. This includes, among other things, modular construction and modernization approaches, the use of prefabricated building components, and the assessment of environmental impacts and circularity at early planning stages.
This systematic approach also addresses rising demands for waste prevention and material recycling, as well as potential risks related to limited resources and increasing material prices. Looking ahead, we aim to further anchor circularity as a criterion in our planning, tendering, and procurement processes. To that end, we analyze environmental impacts and lifecycle costs of components and products—from production through operation, maintenance, and renovation to deconstruction—and progressively integrate circular economy principles into our product manual.
Further information on our approach to the circular economy can be found in Chapter E5 of our annual report.
At Vonovia, we are strengthening our commitment to efficient waste management in our residential neighborhoods. We are continuously driving the expansion of sustainable recycling and recovery methods across our neighborhoods. As part of a pilot project, we systematically analysed green waste recovery and the separation of recyclables in a selected neighborhood in Essen and will apply the findings to additional neighborhoods in the future.
For renovations and new constructions, we place great importance on installing energy-efficient electrical appliances and increasing the use of secondary raw materials. In response to the increasingly stringent regulations surrounding material disposal, we avoid using hazardous or toxic substances from the outset. Effective waste separation concepts for good waste management and the promotion of recycling play a particularly important role in our construction and refurbishment work, as they enable us to reuse valuable resources like windows.
A significant portion of the apartments in our portfolio were not constructed by Vonovia. Some of these buildings contain materials that were state-of-the-art at the time of construction but are now considered hazardous upon release. Materials such as asbestos, "old" artificial mineral fibers (AMFs), polycyclic aromatic hydrocarbons (PAHs), or lead-based paints in existing buildings are typically removed during maintenance or refurbishment projects or when a new tenant moves in, and are replaced with suitable materials. When the disposal of hazardous or contaminated building materials requires careful professional handling, we expect all of our service providers to comply with applicable legislation and regulations, particularly those concerning health, safety, and environmental protection. Our employees receive regular training on these subjects.
Our findings will be implemented across other neighborhoods in the future. We segregate waste generated in offices and common areas, and refrain from using disposable items in the cafeteria. In Sweden, we engage our tenants in waste separation initiatives and educate them about opportunities in waste reduction and prevention. This approach is part of our strategy to achieve a significant 30% reduction in waste by 2030 in Sweden.
