"Trash economy. The abundance of trash. What are we gonna do with it? Are we gonna put it on an island? Are we gonna make it somebody else’s problem? Or are we going to take the initiative, and take this problem by the horns? Trash economy. You use cubes of trash as money. Everybody becomes rich, it’s a gold rush."

I'd love to see 'mining' defined more broadly here. Sure metals are a great target but every useful and valuable material known to man exists in landfills. A "full cycle" or "total recovery" mindset would be far more exciting. Treat everything as potentially valuable and you get better economics. I'd love to join a company who had this as their mission. Sure, start with metal recovery but continually build out new recovery processes until you can "ingest" everything and turn it into something useful.

this non-issue happened in a modern landfill near my hometown. They just used a different grade of material and pocketed the difference. The chemicals area leaching now into the groundwater. Any researchers reporting on that are sued. Even police is used for intimidation. Country is Germany.

I'm continually surprised by blatant corruption in first world countries. It's like I expect privilege to translate into integrity.

I'm super excited for all the plastic in the world and all the devices that we use everyday to rot because we developed a bacteria that eats it and now your iPhone internals have an infection and your phone just disintegrates and the steering wheel falls off your car

Lots of organisms eat wood and cotton. How often does your furniture and clothing just randomly disintegrate? You really cannot imagine a middle ground between these products existing for millions of years vs. your steering wheel falling apart while you're driving?

> furniture and clothing just randomly disintegrate?

Quite frequently, if you have moths . Like it used to be a major problem before the insect apocalypse and we used to kill them with poisob

There is or was a British inventor who build an odd contraption with 2 vibrating plates with grinded garbage flowing between them suspended in ferrofluid. Along the track the paeticles sort themselves by density. Innitially a silly idea as ferrofluid is expensive but he wanted to see how well it worked and possibly try better fluids. It turned out to produce much more ferrofluid than was consumed. The story ends with: no one was interested enough to spend money on it.

You should visit the average landfill to get a firsthand impression of the sheer volume of trash that arrives every day. Sorting at that point would require a huge investment in infrastructure and technology on-site. Individuals sorting their own trash at the other end of the stream is quite easy and costs only a few minutes of their time. It's like diverting the flow of a tributary stream vs. diverting the Mississip…

Hey big city, we're actually the Mafia. We know where you live and have been financing your election and the next guy's. So stfu and keep paying.

Some years ago, Switzerland completely stopped using landfills. All garbage is incinerated. The resulting slag is then processed to reclaim nearly all metals as well as some other important elements. Of course, the burning creates CO2. However, you don't have to mine and refine metal ores, and the incinerators also generate electricity and district heating. So the ecological balance is actually pretty good. As a fina…

what happens to the remaining mess of thousands upon thousands of unknown and or toxic mixed chemicals?

Can you elaborate which town and landfill?

A trash incinerator in Norway is working on extracting and storing that CO2. So they could end up being carbon negative in the long run
