If plastic shopping bags can be made to be biodegradable, why cant all plastic products be made the same.?

Answer 1

The problem is lifetime.

I put some plates on top of the cupboards at home in a plastic bag. I didn't notice at the time it was biodegradable.

What that actually means in this context is "breaks up into dust after a few months". When I came to get the plates down a year later, I touched the bag and it just crumbled into white dust.

If we made plastic water bottles out of biodegradable plastic, you'd only have a limited amount of time to use them. Same goes for steering wheels, CD cases... sounds great in theory but in practise, biodegradable plastic would have to have a variable lifetime, eg good for 50 years, 150 years etc.

It's better for the environment to build things that last years and recycle than continually replacing them with biodegradable ones. Every time you make something, you need energy. Most of the world's energy still comes from oil and coal.

Answer 2

i think that all shops should be made to change the plastic bags to paper bags like in america. it would be easier to recycle then, and most people would know how to do it.

Answer 3

good question dude! why not change plastic bags to easily recyclable brown paper bags instead like the americans do? i think that's better than plastic.

Answer 4

because a plaastic bag is much thinner than any other plastics so it wouldnt work for all products .

Answer 5

GO BACK IN TIME AND TAKE YOUR OWN SHOPPING BAG'S WITH YOU AND BETTER STILL IF THEY PACKED OUR STUFF IN PAPER BAG'S JUST THINK ABOUT IT AND FORGET THE PLASTIC BAG'S THEY ARE NO GOOD.
