Governance > Understanding Circular Construction

Yashar Naghdi is focused on the adaptation of technology for creating more sustainable cities. He has his Master's of Urban Environment from Ecole Centrale de Nantes and is currently working with Concular on creating an online ecosystem for the circular construction in Berlin.

It is genuinely believed that the innovation within the jargon of Circular Economy(CE) must follow one of the basic principles of Reduce, Recycle, Reuse. This is while both the market and the international public policy are welcoming optimized industrial construction techniques that can save costs by reducing construction waste.

For example, prefabricated building components can enhance on-site assembly and significantly reduce construction time. As mentioned before, 3D printing is generally a fast-track method in creating building components or even entire buildings which can minimize waste generation and the relative consumption of virgin materials.

But the needed principles for recycling or reuse are rather different. The main objective in achieving sustainability through recycling or reuse is based on the eventual values received by the user.

With that regard, in order to close the loop on the life-cycle of the materials and conduct procurements from sustainable sources when designing a building, we must know the value of the materials in the market and its full environmental impact even after the building is demolished. Therefore we believe that creating a material passport is one of the earliest and most promising innovative solutions in the field of Circular Construction.

The implementation of such a database can take place in different formats and how the public and private sector are involved, can vary depending on the existing infrastructure. Governments can initiate implementing material passports for public buildings as an asset management tool which results in cities having more transparency and can enable the 'Urban Mining' methods in the near future.

We have come to understand that, in order to achieve a pragmatic circular strategy, governments have an important role as facilitators for implementing a circular economy. This is because both the innovation and implementation of CE may demand early and high investments which are not possible for private companies that are essentially profit-driven, and have little interest in environmental impacts.

Here, it is also crucial to elaborate on how much involvement governments can have, without staggering the innovative nature of entities such as SMEs and their dynamic approach towards problem-solving. An ideal case for the involvement of the governments in the transition towards CE is when the enablers in the public sector foresee the measures that are most important for overcoming challenges and tend to commission private entities that have the right competencies and innovative factors but lack the necessary access to financial resources.

It is also important to emphasize that in order to achieve meaningful social, economic, and environmental results that are namely the pillars of sustainability, major long-term policy-making, roadmaps and actions need to be undertaken even if the initial construction and investment costs of a circular building might be higher.

This is while not only reducing, reusing, and recycling construction materials is ecologically and morally positive, large returns can be economically expected through consistent construction adaptability and optimization of the supply chain.

In conclusion, we must add that since the government plays a key role in transforming the current construction supply chain to a more circular model, having a cross-sectoral engagement, of all the administrative divisions of a city from the very beginning- is crucial.


About Concular: 

Concular is an online circular construction ecosystem for the private and public stakeholders in the construction industry to have more sustainable options for their procurement and the current linear construction supply chain can be replaced with a more environmentally friendly approach.

Based in Berlin, the creative capital of Europe. We are a growing and dynamic team which is passionate about urban sustainable development and we are dedicating our expertise to create solutions that have a meaningful environmental and economic impact on an international scale.

Concular wants to close the loop in construction by creating an ecosystem where the linear construction supply-chain can be replaced with more environmentally friendly approaches and the surplus of projects or reclaimed materials from demolished buildings, which still have value in the market, do not end up just in the landfills.
