Eating plastic for profit

https://www.theguardian.com/environm...ttles-in-hours

Quote:
A mutant bacterial enzyme that breaks down plastic bottles for recycling in hours has been created by scientists.

The enzyme, originally discovered in a compost heap of leaves, reduced the bottles to chemical building blocks that were then used to make high-quality new bottles. Existing recycling technologies usually produce plastic only good enough for clothing and carpets.

The company behind the breakthrough, Carbios, said it was aiming for industrial-scale recycling within five years. It has partnered with major companies including Pepsi and L’Oréal to accelerate development. Independent experts called the new enzyme a major advance.
The main point of interest is how PET can be recycled effectively using this method.

I'm assuming it works well in specific conditions ..
So humidity ,temperature ,ph ect .. so effectively in a purpose built bio-reactor thingy ...
They've been talking about these bugs and their development for a good few years now , the sooner they start to make an impact on waste streams the better ...

John McGeehan and team are mentioned in the original article and it looks like they too have had a breakthrough.

Scientists have created a new "super enzyme" that can break down plastic up to six times faster than their previous enzyme.

Without studying this my first reaction is that it's like some Repak inspired nonsense. I know it's nothing to do with Repak but it's like some wheeze that they would come up with.

I don't care how many enzymes eat how much plastic but I don't see it making much difference to the amount of plastic getting into the environment. Plastic bottles, packaging etc. needs to be phased out and in the case of hard plastic (bottles) need to have serious deposits put on them so that throwing them into the countryside is akin to throwing money away.

Worse than that ,it'll be the economics of it all , it's going to be competing with oil ,and that's cheap ... Your deposit idea , and putting levies on plastic waste to pay for the reprocessing will work , but only really in developed countries ...
