Sorry, that's just ludicrous. Putting plastic in a dump is much better than letting it kill animal after animal, decomposing into smaller pieces and getting into the food chain. Ideally we design most plastics out, but barring that recycling would be fine - and just burying it is still much better than either burning or letting it drift into oceans.

Your comment's great, except for the first sentence, which is what the site guidelines refer to as calling names in arguments. Would you mind reviewing https://news.ycombinator.com/newsguidelines.html and editing those bits out of your HN comments in the future? I know it seems small, but it has a downgrading effect on conversation. Also, it often doesn't seem small to the person being addressed that way (or some oth…

Thank you for being the net on the outlets of our drainage pipes! Subtle & not unnoticed work.

This seems worse in almost every respect than a hydrodynamic stormwater separator. With the latter, you pop open a manhole cover and suck out the goo with a vacuum truck. With a net, you have to somehow pick it up without spilling the contents. Then you hope you can empty it without destroying it or you replace it. This sounds much harder. Oh, and hydrodynamic separators claim to catch oils, too.

The only benefit I can think of is that it is probably easier to retrofit onto existing installations.

How much do those cost though?

“The public” just voted in a popularity contest. “The public” doesn’t give a shit about coal.

Unless you live in Townsville, Queensland which currently has high unemployment and a new coal mine scheduled to be constructed nearby.

Well colour me pleased that Townsville, Queensland is representative of our entire country.

Australian. I've seen this circle the internet many times, but I've never seen one in the wild at any beach or river outlet.

I doubt that "Australia" Found a Way is putting credit where it deserves to go. It's not exactly a national priority.

You make it sound like Australia has a huge problem with plastic/trash in waterways that "Australia" is actively ignoring.

In general, Australian's culture is to use rubbish bins and keep things tidy.

Sidepoint: I am not sure if it is something only Australians do, but whenever something about Australia comes up, there will be an Australian there bemoaning how badly we do things. Yes, there is always room for improvement, but Australia is so far ahead of most countries in just about any measure that you choose, that one has to wonder where this sentiment stems from.

Wet garbage is extremely heavy and hard to clean up. These socks typically require heavy equipment to remove/maintain. These filters also only work well in very specific drain configurations. Not as effective as the article suggests.

What is specific about a circular drain opening for this to work?

800 pounds? China pumps 4,800,000,000 pounds (2.4 million tons) of plastic into the ocean each year. No, western countries are not perfect. Yes, the vast majority of ocean waste comes from poor, non-Western countries. The US, 3rd largest country by population, is #20 for ocean pollution. China alone produces 1/3 of all ocean waste. https://www.scientificamerican.com/article/world-s-oceans-cl...

Western countries export most of their plastic waste to the countries named in the article. Substantial amounts of the plastics China spills into the ocean are ours, exported there for “recycling”

Why does that matter? The issue is that they claim to be recycling and then just dump it in the ocean instead.

I kayak and fish in the bays of NYC. A fact not known by much of the population of the city is that almost every time it rains, the sewage treatment plants release raw sewage into the ocean. This is due to the storm drains being drained by the same system that sewage is treated from. Due to this the water is filled with trash, floating condoms, and wet wipes. So this isn't just third world countries. It is bad enough that bacteria and nitrogen wastes get into the water when this happens. They should at least capture the trash and disgusting sewage products.
