I wrote recycling and asked my chemistry teacher afterwards and she said it's fine
Thats reassuring. The advantage of chemistry is there are generally several acceptable answers which mean you can make educated guesses. Good luck with the rest of your GCSE's.

This is what my head of chemistry told us to do when it asked for two. We did a past exam question identical to it but with a different polymer
Ah ok, we had been told by our teacher that it was acceptable to draw one link but add a small n at the bottom to show that it was a chain with various numbers of monomers. I'm not 100% though so it may just depend on how pedantic edexcel's mark scheme is

We're also told to draw a small 'n' after it but rather than put a number, draw the whole thing out and leave the 'n' there instead of putting a 2. I assume it's just a different method
Do you think we could have said, recycled. i was tempted to go with incinerated but couldn't decide which they preferred?
I wrote recycled and the starch granules thing. You should have wrote down both recycling and incineration cause remember they'll pick the right one, it doesn't matter if the other points are wrong. If you can't pick between two answers just write both down.
I'm pretty sure that if you were to 'incinerate' a plastic bag, the toxic fumes produced would definitely be far worse. The answer was to put starch molecules in the bag so that micro-organisms could break it up after a while.
Personally, I found the C1 paper A LOT easier than the B1 paper because it covered a good range of topics and didn't lead to much 'wasted' revision; unlike the B1 paper where they didn't half drag on some of the topics they used.

It just asked for another method of disposal, not a cleaner one, so I'm pretty sure you'd get burning/incinerating as well as recycling and starch molecules.
Huh but there were no questions on vegetable oil and calirometry??????
The last question was 5 marks and it asked about gardening vegetable oils. There was not any questions about calorimetry specifically but the question asking about how you could improve the shown experiment, had a diagram of calorimetry

I think you may have the wrong paper for this thread. We did the GCSE Edexcel Higher.
I need your help in the exam i wrote beneath the question but still in the big box which has all the questions in it. Will it not be read now as i though it was still in the big box
