Geisys Ventures Partners with Cal Poly - SLO on "defeatable adhesive" technology

The technology development and consulting company Geisys Ventures, LLC (Geisys) and California Polytechnic State University – San Luis Obispo (Cal Poly) have executed a Memorandum of Understanding outlining their intent to collaborate on the development and commercialization of a novel adhesive technology aimed at expanding end-of-life options for a wide range of consumer products.

Dr. Kristoffer Stokes, CEO of Geisys, explains that many products are manufactured with various glues due to their low cost and ease of use across materials and product types, but these standard glues often prevent separation when it comes time to repair or dispose of the product. And with mixed recycling being possible in only certain energy-intensive recovery facilities, this means that many high-value materials simply end up in a landfill. According to Stokes, the adhesive technology being developed in collaboration between Geisys and Cal Poly—a “defeatable adhesive”—will address this end-of-life disassembly issue: a critical but often-overlooked segment of the coveted “circular economy.” Says Stokes, “Our excitement for the potential of defeatable adhesives is beyond measure. This technology provides standard adhesive capabilities with the added benefit of design for disassembly (DfD) methodologies, allowing product developers to reuse components and, ultimately, reduce overall waste.”

The patent-pending technology was initially developed in a Cal Poly laboratory led by Prof. Philip Costanzo with applications in biobased, rehealable coatings. “Our technology reinvigorates established and well-understood science to produce novel and dynamic materials. The procedure is straightforward, scalable, and suitable for completion by undergraduates, which demonstrates the robustness of the system,” said Prof. Costanzo. Utilizing specially designed polymers that can dynamically reconfigure themselves, Prof. Costanzo’s concept showed promise in adhesive applications. And early collaborations between Geisys and the Costanzo lab have confirmed the adhesive capabilities of these “smart” materials. This step forward is the result of a two-year partnership between the two groups.

Cal Poly has a mission to foster teaching, scholarship, and service in a “Learn by Doing” environment in which students, staff, and faculty are partners in discovery. As a polytechnic university, Cal Poly promotes the application of theory to practice, and this has been a critical aspect to the success of this joint project. This technology has been driven and developed by undergraduate students learning about how polymer science can be adapted to make more eco-friendly manufacturing approaches. Prof. Costanzo further states that “Our students get hands-on experience solving real world problems. This develops their technical abilities as well their critical-thinking and problem-solving skills.”

“We are excited to partner with Geisys Ventures on this important technology, highlighting Cal Poly’s focus to develop market transforming technologies with our private sector partners,” said Jim Dunning, Cal Poly’s Associate Vice President of Corporate Engagement and Innovation. Geisys plans to continue development and investment in this technology and is working to scaleup for manufacturing trials in the near future.
