However, cost is currently a prohibitive issue to widespread use, the researchers said. While petroleum is readily available to siphon from the ground, widespread infrastructure for algae farming will be needed for plastics made of the bio-based polymer to become used en masse, Burkart said.

However, the process the researchers devised can also be applied to other plant-based material, Burkart said.

The researchers hope their new process can eventually be implemented widely for food packaging, Pomeroy said.

"But if you're going to ask me, 'Could we do this with anything?' I'm pretty sure we could do this with most anything," he said.

Sounds like an economy of scales problem, and the scale isn't there. Fixable, but not great.

No he said that in the video. It's a moot point. We are looking at doing something new. Will it be price competitive once it matures? Thats what we need to be asking.

Because if yes, immediately shift ALL subsidies from petroleum to whatever CAN effectively replace oil-plastic.

Whatever we do, it has to actually be effective regardless of cost. Cost come down as economies of scale sort themselves out.

Plastic is killing us anyway, what cost matters if we are all dead?

This is a problem NOW. Paying for it is a problem LATER.
