Small plastic parts often found on beaches - what is this?

Can anyone ID what this is, where it comes from? It is found very often in beach sand samples from northern Taiwan:

Asking for a friend who is researching Microplastic and other plastic pollution in Taiwan:

I’m sure I’ve seen one of these before, can’t remember where though. At a guess based on the size and shape I’d say part of a cheap flow reducer for a faucet or shower, could be completely wrong though!

Hmmmm… I think too thick (high) and too much open space for a flow reducer. Thanks for the guess, though!

Perhaps some form of faucet aerator or mixer? I’d say bring it to your nearest B&Q and find the oldest looking staff member and ask them. Failing that your nearest Shui Dian store.

@olm It is used for water treatment.
I sent a tweet to Dr. Alexander Kunz to let him know.

Search for ‘K1 Media’ or ‘Bio Balls’

Made from High-Density Polyethylene (HDPE).



Worth a watch!

Thanks slawa.

This needs to be banned immediately.

This is a totally fake filtration system, probably invented you-know-where, when there are far better options that have served civilized societies for more than 5,000 years.

Rocks, sand, and charcoal, for example.


I dug a bit who invented it and who bought them out and guess what name came up?


Wait, I know that name!

Shittiest Water Company that scammed shitload of communes in Europe they even made a movie ‘Water Makes Money’ about them:

Bribed officials to privatize water treatment. Increased prices, did no maintenance. $$$ Government forced to buy back and fix broken plants, pipes because people need quality drinking water.

On a related note, there’s a beach in France where old Garfield novelty phones from the 80’s keep washing up. It turns out they’re from a lost shipping container that got stuck in a cave that can only be accessed briefly at low tide, so they can’t get the rest of them out.

I suppose it can happen anywhere on the planet. :earth_africa: :doh:

Awesome @slawa, thanks a lot!

Shameful stuff.

Knew I’d seen them somewhere before! Aquariums! No wonder there are so many of them flushed into the sea.

They are filtering the ocean?

New question from the same guys. What is this?

Note: the orange/red boxes, not the plastic spoons or anything else in the photo

Bait boxes?




Filthy fishermen of Taiwan .
