The circular economy is no longer a niche concept in construction. In Europe, it is becoming regulatory infrastructure. The EU Taxonomy for Sustainable Activities, the Construction Products Regulation, and the forthcoming Digital Product Passport all push in the same direction: the days of treating buildings as linear systems (extract, build, demolish, landfill) are numbered.
Türkiye is not inside the EU. But it is not insulated from these forces either. Turkish construction exports, contractor operations in European markets, and the investment appetite of European institutional capital into Turkish real estate all create transmission mechanisms. What starts as an EU regulatory requirement ends up as a Turkish supply chain expectation within a few years.
The current baseline
Türkiye generates an estimated 60–70 million tonnes of construction and demolition waste annually, according to data from the Ministry of Environment, Urbanisation and Climate Change. A significant proportion of this arises from the urban transformation programme, the government-led effort to replace pre-1999 earthquake-risk building stock,. The scale of demolition involved is extraordinary by any international standard.
The recycling rate for this waste stream is improving but remains well below European benchmarks. Concrete rubble is increasingly crushed and reused as road sub-base or fill material, a form of downcycling. Structural steel recovery is well established, driven by the economics of the scrap market. Brick and masonry recovery remains limited. Finishing materials such as plasterboard, insulation, flooring, and fixtures are largely landfilled.
The gap between the volume generated and the capacity to process and recover it productively is the central challenge.
What the circular building lifecycle framework reveals
A circular building lifecycle framework maps the material flows and decision points across a building's full life, from design and material specification through construction, operation, renovation, and end-of-life. Applied to the Turkish context, this framework reveals several structural bottlenecks.
The first is design for disassembly. The dominant structural system in Türkiye, reinforced concrete frame with masonry infill, is inherently difficult to disassemble. Concrete and brick are bonded. Steel reinforcement is inaccessible without destruction. When the building reaches end of life, the most efficient recovery path is crushing, not disassembly. Shifting to dry-connected steel or engineered timber structures, or hybrid systems that combine concrete cores with demountable infill, creates a fundamentally different end-of-life profile, but requires a change in both design culture and contractor capability.
The second bottleneck is material documentation. For recovered materials to re-enter a productive supply chain, their specification, condition, and provenance need to be known. In Türkiye, as-built documentation is often incomplete, inconsistently maintained, or simply unavailable. Without material passports or digital building records, recovered materials trade at a steep discount to virgin materials, or do not trade at all.
The third bottleneck is market infrastructure. Circular supply chains require intermediaries: sorting facilities, testing laboratories, brokers, and logistics providers that handle non-standard material flows. Türkiye has the beginnings of this infrastructure in the steel and aggregates sectors. It is largely absent for glass, insulation, and engineered wood products.
Where the opportunities are
Despite these challenges, the conditions for progress are unusually favourable in Türkiye right now, for three reasons.
First, the urban transformation programme is generating enormous volumes of demolition material in predictable locations and on known timelines. This creates an opportunity to plan circular recovery operations, something that is much harder when demolition is dispersed and unpredictable.
Second, Türkiye's industrial base, particularly in steel, ceramics, and prefabricated concrete, gives it genuine capacity to absorb and process recovered materials at scale. The infrastructure investment required to upgrade existing processing facilities is lower than it would be in a market starting from a lower industrial base.
Third, European institutional investors are increasingly applying circular economy criteria to their real estate portfolios, including assets in emerging markets. Developers in Türkiye who can demonstrate credible circular credentials, through tools like the Circular Development Score, will have access to a lower cost of capital than those who cannot.
What investors and developers should do now
Position before the regulation arrives. The Turkish government is developing its National Circular Economy Action Plan. European-aligned building standards are likely to follow. Companies that have already built circular capability in design, procurement, and end-of-life planning will find compliance straightforward. Those that have not will face a disruptive retrofit.
Invest in documentation. Material passports and digital building records are not expensive relative to total development cost. They are, however, genuinely transformative for end-of-life value recovery. Making digital documentation a standard deliverable on every project today creates an asset that will be worth considerably more in 20 years.
Engage the supply chain early. Circular outcomes are not delivered by developers alone; they require contractors, material suppliers, and logistics providers who understand and can execute circular design intent. Building those relationships now, before they become table stakes, is a competitive advantage.
The circular economy transition in Turkish construction is not a distant prospect. It is underway. The question is not whether to engage with it, but when and how.
