Why are we asked to remove lids from plastic bottles when recycling? Many of them carry a recyclable logo.?

The plastic is a different color and they do not want to mix the colors. You get a higher price when the plastics are not mixed. Some plastics have a different molecular composition.

Good question, maybe it because there a different colour or because the plastic is thicker or they crush them before there melted, but i don't actually know

Wellll I guess its because of the firm air spaces that leaving the tops on create, a lot of them left like this would take some crushing, actually the best thing to do is squeeze them flat under your arm and then screw the top back on!!

I think they do not want any liquids in them.

just remove the lids but include them in your recyclables. i'm sure it has something to do with the machines they use.

its so the bottles can be crushed and compressed more, if they have the lids on they take up more space because the air can't get out.

I believe it help in crushing them as well as keeping people from weighing them down with water to make more money off recycling.

Maybe, the bottles will build up pressure with the lids on and explode. Hot exploding plastic doesn't seem fun at all.

I never realised that, now i'll throw in the lids too. Cheers
