Phoenix-based materials company Supersede has secured a $5 million catalytic loan from Closed Loop Partners to expand production of its engineered structural materials made from recycled plastic waste. The funding will support manufacturing equipment installation at the company’s new Midwest facility, which is expected to begin operations in summer 2026.
The announcement was confirmed through official statements published by Closed Loop Partners and supported by company updates shared through Supersede’s official channels, including LinkedIn. The financing marks another step in the growing demand for alternative construction materials designed to reduce reliance on traditional plywood and wood-based panels.
Funding Aims to Scale Manufacturing Capacity
According to Closed Loop Partners, the loan comes through its Catalytic Capital & Private Credit division and is intended to help Supersede increase production capacity as demand rises across several industries.
The company’s upcoming Midwest manufacturing facility will support additional production lines beyond its current Arizona operations. Reports indicate the new site will accommodate at least eight more production lines, significantly increasing output capacity for its structural panel products.
Supersede said the expansion will also help strengthen domestic supply chains for recycled polypropylene materials used in its manufacturing process.
Alternative to Traditional Plywood
Founded by CEO and co-founder Sean Petterson, Supersede develops engineered panels designed as replacements for marine-grade plywood and oriented strand board (OSB). The company’s flagship product, the Supersede Marine Board, is manufactured using recycled industrial plastic waste.
The panels are designed to be waterproof, rot-proof, mold-resistant, and fully recyclable. The company says the material performs better than conventional plywood in areas including water resistance, dimensional stability, durability, and fastener retention.
Supersede’s products are currently used across marine manufacturing, recreational vehicles, specialty vehicles, modular housing, and residential and commercial construction markets.
Growing Demand for Circular Construction Materials
The investment comes at a time when manufacturers and builders are looking for alternatives to traditional wood products due to supply chain instability, rising material costs, and sustainability concerns.
Closed Loop Partners said Supersede’s manufacturing model supports circular economy goals by using recycled industrial plastics that are often difficult to recover through conventional recycling systems. The company also operates a buyback program that allows used materials and production offcuts to be reprocessed into new panels.
Sean Petterson stated that the funding will help the company meet increasing market demand and accelerate its next phase of growth. Closed Loop Partners executives added that expanding end markets for recycled materials is becoming an important area of investment within the circular economy sector.
The latest financing follows Supersede’s earlier $10 million seed round announced in 2025, which included participation from Closed Loop Partners and other strategic investors.
