Perhaps narrow your role and allow someone else to be responsible & accountable for driving the business side of things?

Take an honest assessment of how you can meaningfully contribute and concentrate on that, and pass the reins over to someone else who specializes in handling reins. Where are you best? Pushing forward on a long-held vision, planting a flag in the ground and rallying everyone to it, while ignoring petty concerns like a positive balance sheet? Great! Delegate that latter one to someone who specializes in it and then cooperate & thrive with them.

On the other hand, the plastic industry needs reform. Only about 1/3 of plastic produced is recycled in practice, and even then only once. Hardly the recyclable miracle that the plastic lobby has been messaging on since at least the 1990s. And what is the industry's response? Increased production YOY! Want truly recyclable materials, in practice? Glass. Steel, and some other metals. Fibers, like paper, to an extent.

That being said, I see a need for "base-load" plastic. Plastic is useful and we may forever need it, until at least something better comes along. Particular in key single-use applications like health services.
