At Clefs, we operate at the nexus of plastics and sustainability. Our focus is on practical and effective strategies that improve the bottom line and the environmental footprint of your business.
About Clefs Advisory, LLC
Clefs means “keys”, in both the mechanical and musical sense. Finding the right key requires focus, patience, and wisdom – elements not always in abundance when running a business.
Keys unlock doors, but they have to be turned first. We create turning points for businesses ready to align growth with sustainability.
We’ve worked in large publicly traded companies, cash-strapped start-ups, engineered materials firms, and international OEMs. We’ve created and executed go-to-market plans in energy management, composite materials, biofuels, capital equipment, and recycled plastic materials. In each case, the client’s needs were met or exceeded, as measured by increased sales, certifications gained, channel partnerships established, or new markets identified.
No strategy is one-size-fits-all, but there are proven frameworks and tools that can be applied at all levels. We have a few keys at our disposal. Let’s turn them together and unlock your success.

Global polypropylene (PP) is a $120–130B resin platform growing ~4–5% annually, but North American sheet producers and thermoformers are navigating a very different reality: oversupplied upstream resin, shifting demand from PS to PP/PET, rising regulatory pressure, and accelerating interest in food-grade rPP.
