Plywood Rots. Supersede Extrudes Its Replacement From the Plastic Nobody Wanted.
Sean Petterson sold his last hardware company after raising more than $60 million. Now he is in Phoenix extruding recycled polypropylene into a board that boatbuilders are bolting into 2026 hulls - and he wants a micro-factory in every city with a plastic problem.
Oceanworks®
Oceanworks is a Los Angeles-based B2B platform that makes it easy for brands to buy verified recycled ocean and ocean-bound plastic and to fund the cleanup of plastic that has no resale value. It runs a global marketplace connecting collectors and recyclers with major consumer brands, backs every transaction with its Oceanworks Guaranteed traceability system, and sells IMPAC+ plastic offsets that work like carbon credits for plastic waste. The idea is simple: turn corporate demand into a paycheck for the people pulling plastic out of coastlines before it reaches the sea.
