Stop Recycling Plastic Bottles Without Caps On

With the recycling industry in flux, the rules surrounding recycling plastic aren’t always a given. For one, you can’t recycle plastic bags or straws and now black plastic is even becoming a problem. How will we ever know the right way to recycle?

Given the confusion, it makes sense that on a recent Reddit thread, user u/insert-quote-here advocated for taking caps off bottles when recycling, but here’s why that’s a wrong move—by separating a cap from a bottle, you’ve essentially thrown it right in the garbage.

Why? Oftentimes, when caps enter a recycling facility’s sorting process, they get sorted out because of their small size, and are then sent to landfills. As such, caps are now among the most common trash items found in our oceans (which also end up in the food chain when ingested by sea life).

Part of the confusion lies in us thinking we’re making the jobs of recyclers easier by unscrewing the pesky cap, but it’s actually a waste of your time and effort. Caps and bottles are often separated at facilities using water (after being chopped up, they’re separated based on their ability to float. Caps are less dense and float. Bottles sink).

And caps are valuable, too. They’re made of polypropylene plastic, a coveted plastic type among manufacturers and used in everything from storage bins to cutting boards, so throwing them away is a waste of an incredibly useful resource.

So what’s the right way to recycle a plastic water bottle? First, remove the cap and crunch the bottle up from the base until most of the air is removed. Screw the cap back on, the toss the bottle in the recycling bin! It’s easy, as long as you remember that the two belong together.

    "remove lids from containers before placing them in the recycling bin"

      This is the wrong question. Let's reduce our plastics use. Don't buy bottled water in plastic bottles. Use a tap and fill a glass. Find alternatives to grocery items packages in plastic. It isn't as hard as you'd think. Reduce first then recycle

      I discovered this when I rocked up with $50 worth to drop off and spent an hour unscrewing :(

    I'm confused. Is there some magical point in the recycling process where the caps stop being thrown away and start being recycled? "Those pesky caps are at the bottom of the water now, I guess we may as well recycle them."

    We remove bottle tops and caps, and collect them in a 2L milk jug along with any straws and other small plastic parts.
    then when the jug is fill it goes into the recycling.

    Our council website told us this avoids the small plastics falling through the sorting belts.

    Do some research first and not just publish what your friends tell you.

    Yeah, this is also totally wrong for Western Australia. Our local council requests that we remove the lids and actually place the lids in general waste. The recycling sorters we have struggle with separating the plastics and the lids are not recyclable for us yet (annoying, but I'd rather follow those rules and be sure that at least the bottle is being recycled properly and the whole thing not going to landfill).

    I think the key things are:
    1.) Reduce plastic use as much as possible first.
    2.) Don't take any generic information as gospel. Each council has their own rules as to what can and can't be recycled at their facilities (which your waste goes to). So research your local councils rules and go by them.
