Enkei, RadCap & Tarkett Alum Target Circular Construction Market in 2026

LONDON, March 31, 2026 — Female-led Swedish startup Enkei has successfully raised €0.4 million in a pre-seed funding round at a €3 million valuation. The round was led by prominent Danish architect Anders Lendager, alongside RadCap, an investment collective backed by 81 women, and Ulf Mattsson, the former CEO of Tarkett, a global surface materials leader. The funding will accelerate the development and commercialization of Enkei’s flagship product, ReCeramix, which transforms construction and ceramic waste into high-value architectural materials.

Executive Summary

• Enkei secures €0.4 million in pre-seed funding to scale its circular materials innovation, ReCeramix.
• Key investors include Danish architect Anders Lendager, RadCap, and former Tarkett CEO Ulf Mattsson.
• ReCeramix repurposes over 90% construction and ceramic waste into premium design-grade surfaces.
• The investment will support R&D, production scaling, and an expanded commercial rollout.

Key Developments

Founded in 2022 by Lovisa Sunnerholm and Miriam Bichsel, Stockholm-based Enkei aims to address Europe’s construction waste problem, which accounts for nearly 40% of the region’s total waste. While much of this waste is downcycled or discarded, Enkei’s innovation, ReCeramix, leverages over 90% recycled content to create durable and aesthetically appealing architectural surfaces. According to the company, the material rivals traditional options like concrete, marble, and terrazzo in both function and form.

Enkei’s €0.4 million pre-seed funding round includes contributions from several notable backers. Danish architect Anders Lendager, who is renowned for the UN17 Village sustainability project, co-led the round. Other investors include RadCap, a Swedish women-led investment group; Ulf Mattsson, former CEO of Tarkett; and Christina Åqvist, co-founder of the recycling group Vinning. Materials specialists Thomas Granfeldt and Daniel Strömberg also participated, bringing technical expertise to Enkei’s roadmap.

In addition to private investment, Enkei secured €110,000 in EU grant funding under the Interreg program, a cross-border initiative with a total value of €430,000. The combined funding will be directed towards accelerating research and development, refining production methods, and scaling the commercial deployment of ReCeramix. Notably, the product has already been validated in the market, appearing in high-profile interior applications such as bespoke tabletops, window sills, and lighting installations distributed by Nordiska Galleriet and other premium retailers.

Market Context

The construction industry is Europe’s largest waste generator, contributing approximately 374 million tonnes of waste annually, according to European Commission data. Despite growing discourse around sustainability and circularity, the sector remains one of the least circular, with significant portions of waste either downcycled or sent to landfills. This creates a pressing need for scalable, economically viable solutions that can transform waste into valuable materials.

Enkei’s innovation aligns with broader global trends in the built environment, where sustainability has become a key driver for both investment and policy. Governments and private enterprises are increasingly setting ambitious targets for carbon neutrality and waste reduction. According to a report by McKinsey, the global market for green building materials is projected to reach $365 billion by 2030, growing at a compound annual growth rate (CAGR) of 11.7%. Enkei’s ReCeramix positions the company to capitalize on this expanding market, particularly as Europe aims to meet its Circular Economy Action Plan goals.

BUSINESS 2.0 Analysis

Enkei’s funding round is notable not just for its financial implications but also for its strategic composition of investors. The inclusion of RadCap, a women-led investment group, highlights the growing importance of diversity and inclusivity in venture capital, particularly in the circular economy space. Moreover, the involvement of industry veterans like Ulf Mattsson and Christina Åqvist underscores the technical and commercial credibility of Enkei’s business model.

What sets Enkei apart is its focus on commercial viability from the outset. Unlike many early-stage circular materials startups that prioritize concept over scale, Enkei has already demonstrated market acceptance. Its ReCeramix material is not only sustainable but also competitive in terms of price and performance—two critical factors for scaling in the construction and design industries. Additionally, the company’s interdisciplinary team, which spans material science, engineering, and AI, provides a robust foundation for innovation and execution.

However, challenges remain. Scaling production to meet the demands of large-scale architectural projects will require significant capital investment and operational expertise. The company will also need to navigate complex supply chain dynamics, particularly in sourcing consistent volumes of high-quality construction and ceramic waste. Regulatory frameworks, while increasingly supportive of circular initiatives, may also pose hurdles depending on regional variations.

Why This Matters for Industry Stakeholders

For construction and design professionals, Enkei represents a viable pathway to integrate sustainability without compromising on quality or cost. The company’s ability to deliver high-value architectural materials from waste aligns with the growing demand for eco-friendly building solutions. Investors, particularly those focused on ESG (Environmental, Social, and Governance) criteria, will find Enkei’s model compelling due to its dual focus on impact and profitability.

Policymakers and urban planners could also benefit from Enkei’s approach, as it provides a scalable solution to one of the most pressing environmental challenges in urban development. By transforming waste into a resource, Enkei contributes to the broader goal of building circular cities, where materials are continuously reused within the system.

Forward Outlook

Looking ahead, Enkei has outlined an ambitious roadmap that includes scaling its production capabilities and expanding its product portfolio. The company plans to evolve from small-scale, high-margin applications to large-scale architectural projects within the next three to five years. In the long term, Enkei aims to establish a platform for circular materials, enabling the construction industry to achieve greater resource efficiency.

While the company’s current focus is primarily on the European market, its business model and technology have global applicability. As regulatory pressures and consumer demand for sustainable solutions continue to rise, Enkei is well-positioned to become a key player in the circular economy. However, execution risks remain, particularly in scaling operations and managing supply chains.

Key Takeaways

• Enkei raises €0.4 million in pre-seed funding, led by renowned investors in sustainability and recycling.
• Flagship product ReCeramix transforms construction and ceramic waste into premium architectural materials.
• The funding supports R&D, production scaling, and commercial deployment.
• Enkei is a female-founded and majority-women-led company, emphasizing gender diversity in leadership.
• Long-term plans include scaling to large-volume architectural projects and developing a platform for circular materials.
