What you also forgot to mention is just how much trash we generate… that would be a massive limiting factor as well. It’s hard enough to get a few tons of stuff on a rocket going to space. I couldn’t get an exact figure on a quick google search but humanity generates somewhere on the order of tens of thousands of metric tons of trash per day

First - The major problem with trash isn’t the getting rid of it part, it’s the gathering it up part. If we could do that, it wouldn’t be a problem.
Second - Launching things on a rocket is kinda dangerous still, there’s a risk the rocket will blow up on launch, scattering the material across a large area. This is a big reason why things like nuclear waste is a problem to transport in general, much less flying it somewhere.
Third - Launching something into the SUN is really hard, it would be easier to send something out of the solar system than back into the sun.

Fourth - Someday we’ll figure out a use for everything, wall-e style. If we dump everything into a centralized landfill, we’ll eventually be able to collect/sort/recycle it into something useful. Throwing it into the sun (or off-planet) would make that stuff unavailable forever.
Finally - Throwing stuff into the sun would actually get rid of it forever, yes. It would be completely decomposed into the atoms it was made from. If we threw ENOUGH heavy metals into the sun, we could actually poison the sun making it not able to fuse hydrogen anymore, but even if we threw the entire earth into the sun, it wouldn’t be enough.

The frustrating part is that this could be the easiest to solve. Require boats to weigh in and out, and account for everything on board. Minus fuel, plus fish, but those old, broken nets and plastic waste need to return to port to be properly disposed of. Throwing even a soda can overboard should result in significant fines.

How do you weigh a boat precisely enough to detect a soda can missing?
themeatbridge@lemmy.world 1 month ago
Fair question. You’re not going to catch a soda can, but a boat should be a closed system. The thresholds should be as low as is practically enforceable.

A lot of ocean trash comes by river from poor countries.

Ocean trash comes from plastic manufacturers. Responsible wealthy countries ship their dutiful recyclables to garbage pits in poor countries.
Most poor people don’t even have the education or resources to polymerize crude into poly-vinyl, it’s harder than you’d think.

Also by river from wealthy countries, and has done so for centuries.
The scope of the task of removing it is far bigger than OP can imagine.

Most of the plastic in our oceans comes from land-based sources: by weight, 70% to 80% is plastic that is transported from land to the sea via rivers or coastlines
Most of the world’s largest emitting rivers are in Asia, with some also in East Africa and the Caribbean
Seven of the top ten rivers are in the Philippines. Two are in India, and one in Malaysia. The Pasig River in the Philippines alone accounts for 6.4% of global river plastics
Rich countries tend to have better functioning waste collection and disposal services.

Also, sending things to space is way, way, way worse for our planet per kg of stuff, because of the fuel and parts that it takes

How can earth have enough heavy metals for that?
mipadaitu@lemmy.world 1 month ago
You misread, I specifically said that Earth doesn’t have enough mass for that.
Vilian@lemmy.ca 1 month ago
True, thanks

Another problem is that each item we throw into the Sun is comprised of atoms. We would literally be taking the atoms that makes up earth and throwing them away to a place where the atoms would no longer be part of earth. While a McDonalds cup isn’t going to catastrophically change earth, do it enough times and we could see a problem.
