In July 2025, Aduro became a member of the Plastics Industry Association (PLASTICS) and the Polystyrene Recycling Alliance (PSRA), an initiative of PLASTICS focused on advancing polystyrene recovery. Membership in these organizations connects Aduro to a broad network of resin producers, recyclers, converters, and brand owners engaged in advancing recycling standards, infrastructure development, and circular economy initiatives.

Participation in PSRA provides Aduro with a forum to collaborate on the technical and market challenges unique to polystyrene, one of the more difficult plastics to recycle due to limited collection infrastructure and low recovery rates. Aduro’s early-stage work converting polystyrene into targeted hydrocarbon intermediates using Hydrochemolytic™ Technology aligns with the Alliance’s objectives of supporting innovation and developing viable end markets. This work builds on the Company’s previously disclosed patent filing covering the production of BTX (benzene, toluene, xylenes) from waste plastics and renewable oils, further highlighting the applicability of HCT to polystyrene recovery.

Feedstock Innovation – Synthetic Turf Testing
In July 2025, Aduro announced the completion of testing of synthetic turf waste, commonly used in sports stadiums and landscaping, using its Hydrochemolytic™ Technology with encouraging results. Synthetic turf represents a complex waste stream, composed of multiple materials that are typically difficult to recycle. The tests focused on the polyolefin components, where HCT demonstrated the ability to convert these fractions into shorter-chain hydrocarbons under controlled conditions. This was achieved without extensive preprocessing, as the process demonstrated tolerance for the mixed materials and contaminants typically present in aged turf systems. As part of this initiative, the Company received synthetic turf samples from a global industry stakeholder for evaluation. Several other parties have expressed interest in the results, underscoring the growing demand for chemical recycling options in this segment.

While still at an exploratory stage, the results highlight an area of potential application that has attracted interest from external parties, reflecting the need for innovative approaches to turf and composite waste materials.
