We really owe it to future generations to figure out effective, energy efficient plastic recycling. This seems to be a big step. The economic barriers are huge here, oil is going to be cheap for a while yet.
That said, it is a bit concerning that this could escape into the wild. Plastics are harmful long term but it’s crucial to society that they don’t just start degrading.
Why? Plastic is made from oil. Oil exists deep in the earth, more or less permanently. If we extract oil, convert it to plastic, and then sequester the plastic permanently, e.g. via a landfill, then that seems net neutral.
Yes plastic ends up in the ocean. But most plastic waste in the ocean comes from recyclables shipped from first world to third world countries with poor refuse control.
Extracting oil is an expensive process that has environmental consequences, and storing plastic after the fact requires land and can result in plastic leaching into the environment. There are also other petroleum byproducts between extraction and having usable plastics.
With that in mind being able to recycle plastic cheaper than creating it from oil would be an economic and environmental win.
As a small factual change I can not find any evidence for the statement that most plastic waste comes from shipped recyclables. I'd love a source for that.
Almost all plastic recyclables in the US is shipped to Asia and Africa. It’s simply not profitable to process here.
From the article:
Recently, however, China has made efforts to curb waste.
For years the country had imported millions of tons of recyclable waste from overseas, but a growing recycling burden at home prompted the government to shift its policy.
It is profitable to recycle plastic if you can pay people a few dollars a day to sort through it all to find the valuable pieces.
China’s change in recycling policy was caused by, among other reasons, a documentary on the workers who sift through the countless volumes of plastic waste. It’s quite sad: https://m.youtube.com/watch?v=6qZwo6U5YFY
The packed that waste on fishing ships who dumped it on the way out and brought back fish. So basically, we dumped our plastic into the ocean, but with a clean consciousness after a convuluted process..
Can we stop pretending that whatever bejing decrees becomes reality in the country it claims to rule over? Its a nice play-pretend facade and the socialist inspired reality below is usually quite dystopian..
The source you provided says that exports from North America are around 751,000 tons annually, with only 300,000 tons exported outside of North America. This NYT article says exports from the U.S. alone is 48 million tons, 25 million of which go to poorer countries [0].
Data for January showed that exports of scrap plastic from the United States edged upward, to 48 million tons from 45 million tons the previous January. Exports to poorer nations were virtually unchanged from a year ago, totaling 25 million tons.
If these larger export numbers are correct, then the estimates in the article you provided should be multiplied by a factor of 10 at least.
Plastic stuffs become microplastics. Which are now everywhere, from mountain tops to breast milk. We are only just starting to glimpse the impact on ecologies, public health, reproduction rates, ad nauseum.
The principle of harm reduction dictates that society should take a few steps back and figure out what's going on.
True but I think the broader point still stands. Natural gas would either stay sequestered, leak into the atmosphere as an even more potent greenhouse gas, or breakdown into CO2.
We really owe it to future generations to figure out effective, energy efficient plastic recycling.
Why do we owe it to the future? We can just stick the plastics in a land fill and deal with them later. They don't degrade (much) after all.
Perhaps oil will become expensive enough, and recycling good enough, that it will makes sense to mine landfills in the future.
(I agree that putting plastics in the ocean or so is probably not a good idea. But that doesn't mean recycling is the only alternative, especially when it doesn't make economic sense.
Btw, most plastics also burn well. So waste-to-energy plants might also make sense.)
I mean there's food-grade paraffin and beeswax wax can act as a polymer that addition of heat will reform. I can remember thinking as a kid, "why can't we just melt all this crap down?"
I guess call it indoctrination since reuse, conservation, recycling is something taught to kindergarteners, but even at face value the lifecycle obviously a cost -- trash management, elegance (due to litter, and bad packaging), the risks of petroleum mining/hydraulic fracturing, presumably greenhouse gas emissions, microplastic contamination, risks of sloppy chemical engineering/benzene contamination... all costs centered on crap that mostly sucks as a product to begin with... an idiotic matryoska doll of nested garbage.
The requirements get tough at those scales, for the full life cycle I suppose, iterating on any component effectively is a lifetime of work. Oh you can melt it, what about nonremovable contaminants? how much energy input did that cost? I don't see any clear-cut solution except to eliminate subsidies at a solution-dependent rate.
Grow plants, use plants to make plastic, use plastic for all kinds of great things, bury used plastic deep underground forever as a form of carbon sequestration. Repeat.
That seems highly unlikely, and with efficient recycling, completely unnecessary. There are a number of uses where plastic is the best solution - economically and environmentally.
There are countless applications where anything other than plastic really makes no sense, or is quite impractical or even impossible. The idea of eliminating plastics is pure fantasy.
Even reducing them doesn't make that much sense. The amount of energy needed to recycle metals is generally much higher.

90% of river-borne ocean plastic comes from 10 rivers in Asia and Africa: https://www.weforum.org/agenda/2018/06/90-of-plastic-polluti...

Sounds like it isn't profitable there either, so why are we shipping it

We pretend to recycle and they pretend to care..
I'd like to see a source for this because I don't believe anything of it. I only found an article saying it's not true https://ourworldindata.org/plastic-waste-trade

A great deal of plastic is made from natural gas, not oil.
True but I think the broader point still stands. Natural gas would either stay sequestered, leak into the atmosphere as an even more potent greenhouse gas, or breakdown into CO2.
Multiples of the carbon in plastic is released in it's production.

It's always been confusing why this isn't as simple as running the dishwasher.
Why would you expect it to be?

Simple things are expected due to a lack of understanding of the complexity of the problem
Funny enough, even supposedly simple dishwashers are already marvels of engineering.
Grow plants, use plants to make plastic, use plastic for all kinds of great things, bury used plastic deep underground forever as a form of carbon sequestration. Repeat.
Recycling plastic is pointless.
It is crucial to society that we transition away from them almost completely
That seems highly unlikely, and with efficient recycling, completely unnecessary. There are a number of uses where plastic is the best solution - economically and environmentally.
Why? What bad things do you expect to happen?
Enjoy your laptop made of bamboo.
That actually sounds dope.
Apple laptops are largely made of aluminum, I think.
There's some plastic in there, eg for the keyboard. But removing 90% of plastics would solve 90% of the problem they pose. No need for purity.
(I'm just playing devil's advocate here. I don't actually think plastics are necessarily all that harmful.)
There are countless applications where anything other than plastic really makes no sense, or is quite impractical or even impossible. The idea of eliminating plastics is pure fantasy.
Even reducing them doesn't make that much sense. The amount of energy needed to recycle metals is generally much higher.
To what?
