For over 50 years, the Danish contracting company Enemærke & Petersen has been among the leading companies in the renovation of Denmark’s social housing. The company is known for its deep understanding of existing buildings and its ability to keep up with the times. Through major partnerships with municipalities and housing associations, Enemærke & Petersen has been behind some of Denmark’s most significant and transformative renovation projects and today plays a central role in the development of circular construction in Denmark.
Enemærke & Petersen are working purposefully to integrate circularity into their workflows. We sat down with Frederik Gade Lind, the company’s Resource Coordinator and Sustainability Consultant, to discuss developments in the construction industry, the role of the individual in the transition toward a more circular paradigm — and, in particular, how he is working to foster a new mindset within the company.
A Pursuit of Regenerative Building Systems: Frederik’s Practical Approach
Frederik has worked on the front line with biogenic materials and circular solutions. His journey into sustainable construction gained momentum at JaJa Architects, where he participated in an experimental housing project that compared timber, concrete, and masonry in order to assess their environmental impact.
His hands-on work with the timber house gave him insight into challenges such as Danish fire regulations, which limit the use of biogenic materials, and this was further deepened through his experience with life cycle assessments, risk analysis, and the practical barriers to sustainable design.
“I didn’t know the regulations when I started, and that made it easier to question them,” he says, reflecting on his unconventional path into the construction industry.
At Enemærke & Petersen, Frederik bridges the gap between research and practice: he conducts circular screenings of demolition projects to identify materials that can be reused either on-site or in new construction; he prepares sustainability proposals in tenders, including ideas such as reusing materials with low environmental impact; and he leads development projects that explore biogenic and circular construction methods.
Frederik works closely with architects, engineers, contractors, and clients to establish shared goals across disciplines. He often acts as a connector and trust-builder, helping to create a common direction that makes circular solutions possible. His approach combines technical expertise with the ability to drive change — with a clear understanding that although many in the industry want to improve, it requires a collective effort to demonstrate how circularity can be practical, at times cost-effective, and meaningful.
The Hidden Costs of New Construction – And the Case for Renovation
Despite Denmark’s reputation for ambitious climate policy, Frederik points to a clear contradiction. “We are still building far more new projects than we are renovating. And every new building results in enormous amounts of hidden waste, material consumption, time, and CO₂ emissions that we simply cannot afford.”
Between 12–30% of materials in new construction are already wasted during the building process itself. Even more alarming is the fact that Denmark spends billions every year correcting defects in newly constructed buildings — a result of rushed work and a lack of focus on craftsmanship quality. [1]
For Frederik, it is an economic opportunity.
“The circular economy solves nothing if we do not reduce our level of activity. Stopping unnecessary new construction and focusing on transforming what already exists is our greatest opportunity.”
Building Bridges Across Disciplines – For Real Change
Systemic change requires more than technical solutions. Frederik sees systemic culture as the real challenge. He views his role at Enemærke & Petersen as a bridge-builder between architects, engineers, contractors, and clients — each with their own incentives and perspectives. The goal is to unite everyone around outcomes rather than rigid processes. “We need to take shared ownership of the goal, not the path to get there. If we remain flexible and listen to each other’s strengths, we can find solutions that none of us could have found alone,” he says.
The barriers are significant. For example, fire classification regulations make it difficult to use materials such as timber or straw unless they are fully encapsulated in gypsum — regardless of their actual fire performance. Reused or biogenic materials often lack the documentation required by legislation, standards, and regulations, and unless there is a clear financial benefit or demand from the client, most stakeholders choose the safe and conventional solution.
One of Frederik’s most promising examples of measurable impact came during a sustainability workshop with a private developer. The starting point was a planned aluminium façade with a high CO₂ footprint. Instead, Frederik proposed reusing red clay roof tiles from a previous demolition project. Preliminary calculations indicated a potential CO₂ reduction of approximately 77,000 kilograms — at no additional cost. The façade has not yet been constructed, but the response was positive, and several tests have been carried out to evaluate the solution. The proposal demonstrates how practical and economically sustainable circular solutions can shift mindsets — even before they are implemented.
Frederik’s Vision for a Regenerative Construction Sector
Frederik highlights seven key initiatives to rethink the construction industry:
Prioritize renovation over demolition: “We need to transform what we already have. It reduces waste, lowers emissions, and saves costs.”
Introduce a burden of proof before demolition: Legislation should require developers to document that a building cannot be reused before demolition is approved. “A simple rule like this could transform Denmark’s construction industry overnight.”
Revive craftsmanship: Train skilled professionals in precision and quality so that we build durable, high-quality buildings free of defects.
Shift ownership to communities: Move away from rigid hierarchies and give more stakeholders a voice in decision-making. This strengthens a long-term, locally rooted perspective.
Collaborate locally and across industries: For example, by using agricultural waste in construction.
“Insutex is a good example,” says Frederik. “In my opinion, the product is a strong player in the insulation market — particularly because it succeeds in connecting industries by using residual materials from one sector in another.”
Introduce material passports: Digital records of materials’ composition and origin enable reuse and reduce waste. “If we know a material’s properties and where it comes from, we can reuse it more effectively.”
Create trust-based partnerships: Replace conflict-escalating contracts with relationships built on shared goals and long-term collaboration. “Long-term, trust-based relationships founded on shared ambitions are the key to real progress,” says Frederik.
Enemærke & Petersen’s Strategies for Sustainable Construction
The team at Enemærke & Petersen is working on multiple fronts to promote circularity and efficiency on construction sites. There is a strong focus on smarter resource use, including reducing electricity and fuel consumption, improving waste sorting, and carrying out selective demolition with reuse in mind. Through collaboration with Genbyg, used building materials are given a new life. A notable example is the Kildebjerg Ry project, where approximately 9,000 m² of BEWI GreenLine EPS — 100% recycled expanded polystyrene — was used to insulate the ground slab, demonstrating reuse on a large scale.
The company also participates in development projects such as Det Biogene Montagebyggeri (prefabricated elements with straw façades), Woodcircles (reuse and upgrading of timber into CLT, glulam, and wood-fibre insulation), and Rønnebo CØ (reuse of concrete slabs). These projects are driven by highly skilled professionals with research backgrounds, including a PhD in platform thinking in prefabrication, a postdoctoral researcher in design for disassembly, and a PhD focused on how diversity can foster innovation. Altogether, this reflects Enemærke & Petersen’s commitment to practical, circular solutions across all phases of construction.
The environmental impact of the construction industry is well documented — but so is its potential for change. The work of Frederik and Enemærke & Petersen reminds us that real transformation begins with people who dare to ask questions, build connections, and shape a new construction practice.
