See also the German 'Green' party whose policies have led to lots and lots more CO2 emissions over the years.

Also, Greenpeace energy selling organic gas. That’s is very funny until you realise that 1) they are serious, and 2) they vote.

I've seriously wondered about this. Tell us more. Do you just act as a private middleman to get things to the dump? Do you sort or resell?

Yes it’s a private subscription based hauler like like Waste Connection, Waste Management etc… However, we’re only ever going to do residential because the goal is to grow ownership of waste infrastructure to employees of the cooperative and cooperators, as well as homeowners with returns on their recycling and any other services Eventually, the goal is to provide all community services, including banking and general…

This is fascinating. I love that your goal is to compete with the status quo US services and society without apology. Good luck!

Landfills certainly require more power to operate than that gas scheme can provide later. It all sounds and reads like a fairytale but none of this is sustainable.

This is my argument against recycling. It is not sustainable to recover a tiny amount of energy when balanced with the extra diesel-guzzling truck traversing the neighborhood. All so we can think we're "making a difference" by keeping plastic bottles out of a landfill.

It’s a good thing we have electric motors, then. An additional benefit is that they are much less likely to wake you up when they get your bins at 5am.

Unless you can wish natural gas into existence, that means keeping a lot of infrastructure and storage just in case.

I'll pitch in. Standardize on a strict set of allowed mixtures of plastics (and possibly even colors!). Not just "PP", "ABS" and so on, but exact formulas. Also, keep the set of allowed formules small. This will serve two purposes, first, allow plastics to be actually recycled to a greater extent. Now, plastics are very much "mystery" items. Second, it will reduce the amount of harmful and toxic additives in plastics…

How do you make China adhere?

You don't and they won't.

Do you mean "renewable" gas? https://green-planet-energy.de/privatkunden/prowindgas

I can't find anything about "organic" gas, maybe your auto translate did a wrong thing?!

Is that actually true?

If you mean "over the last 20 years", then no, they weren't even a governing party between 2005 and 2021.

You're perhaps talking about the downstream effects of sunsetting nuclear energy but even since then, the ratio of renewable energy has only increased. So what do you mean exactly?

This was quite interesting -- but I only found that because it had a transcript.

Which is why I like transcripts. It is apparently a ~17 minute video. Time to read (for me): 2½ min. I timed it.

I'll give 2min to learn about rubbish management, a subject I'm not particularly interested in. I won't give ⅓ of an hour to it though.

If you're making a video, provide a transcript.

Oxide Computer: this especially applies to you.

I wonder if in 100-500 years they will mine landfills for materials or elements that have become scarce. Or maybe they will just keep them as natural gas reactors.

There's a kids sci-fi novel called The Ear, the Eye, and the Arm that talks about this a bit. There are children searching for plastic in landfills because they've run out of oil to make new plastic. Plastic bowls and things are status symbols because of how expensive plastic becomes.

The Trump administration backed away from policies meant to reduce carbon emissions, and promoted policies meant to increase energy independence through increased reliance on and use of fossil fuels. The same administration also rolled back nearly 100 separate environmental regulations. It supported developing energy reserves on federally protected land, including national forests and near national monuments. Trump h…

I don't know what I read to get a totally opposite meaning of the original comment, but rereading it now does make this ID10T level of WTF

I modified my original comment to replace "people" with "environmentalist" in the first sentence to clarify what I meant—you probably read it before I did that. Sorry.
