Turning Global Waste Into Next-Gen Materials

Fiber Global is tackling one of the built environment’s biggest challenges: the heavy environmental cost of traditional construction materials. Using proprietary technology, the company transforms industrial waste streams - such as recycled cardboard and paper - into high-performance, low-emission fiberboard.

Their flagship product, Forged Fiber Board (FFB), is formaldehyde-free, low in VOCs, and certified UL GREENGUARD Gold. Designed to outperform conventional wood and composites, it offers a significantly reduced carbon footprint, while supporting a scalable circular economy solution.

This approach not only diverts waste from landfills but also unlocks new possibilities in green architecture, furniture, and materials innovation.

Funding with Strategic Impact

The new investment brings more than capital to Fiber Global - it brings seasoned leadership. Ira Ehrenpreis, Managing Partner of DBL Partners, has joined the company’s board. Known for his work with Tesla and other climate innovators, Ehrenpreis brings decades of experience in scaling purpose-driven companies that create lasting environmental and economic value.

The partnership between Fiber Global and DBL reflects a shared belief in building companies that deliver both impact and performance - without compromise.

Redefining the Future of Building Materials

At the heart of Fiber Global’s growth is a vision to redefine what building materials can be. Founder and CEO KC McCreery has long championed the idea that sustainable construction doesn't have to mean sacrificing performance or profitability. His focus has been on building a platform where waste is no longer seen as a burden, but a valuable resource - one that can be reshaped into climate-friendly, durable materials that are both beautiful and practical.

With the support from DBL Partners, McCreery and his team are now positioned to scale U.S. manufacturing rapidly, tapping into national demand for clean, cost-effective alternatives to wood, MDF, and composite products. This next phase will focus on making sustainable materials more accessible to mainstream markets at industrial scale.

Market Tailwinds: Why the Timing Is Perfect

With buildings and construction accounting for over 10% of global greenhouse gas emissions, governments and corporations are under growing pressure to reduce their carbon footprint. As ESG mandates tighten and consumer demand for sustainability grows, the market for circular and eco-certified building materials is surging.

Fiber Global is ideally positioned at the intersection of environmental innovation and manufacturing efficiency. By producing locally and using reclaimed materials, the company also minimizes emissions from transport and raw material extraction - creating a compelling sustainability value chain from end to end.
