When it comes to sustainable innovation, CleanFiber has emerged as a serious player striving to revolutionize insulation production by tapping into an unexpected resource: cardboard boxes. While the traditional cellulose insulation industry grapples with dwindling supplies of old newspapers, CleanFiber eyes a different path, capitalizing on the burgeoning abundance of corrugated cardboard.

In a world increasingly shaped by e-commerce, cardboard boxes have proliferated, reaching staggering annual quantities of up to 50 million tons. Yet, their potential as insulation material remains largely untapped due to the formidable challenge posed by contaminants such as plastic tape and metal staples.

Enter in CleanFiber, a visionary startup that foresaw this paradigm shift and embarked on a journey to tackle the complexities of cardboard transformation. Led by CEO Jonathan Strimling, the company has already made significant strides, producing insulation equivalent to 20,000 single-family homes.

However, recognizing the need for scalability, Strimling strategizes beyond the confines of their Buffalo headquarters, eyeing a nationwide expansion. To fuel this ambitious endeavor, CleanFiber secures substantial funding, with Spring Lane Capital leading a Series B investment of $28 million, accompanied by a $31.5 million project financing facility.

Central to CleanFiber’s success is its pioneering production process, which converts cardboard into a viable alternative to traditional cellulose insulation. While profitability remains a guarded secret, Strimling hints at significant progress in cost reduction, a crucial factor in market competitiveness.

Having surmounted the initial hurdles of technology commercialization, CleanFiber sets its sights on the future, navigating the complexities of scaling production. As stringent building codes demand increased insulation, the company stands poised for growth, transcending the need for competitors’ downfall to thrive in an evolving market landscape.
