Brazil implements reverse logistics system for plastic packaging and boosts recycling | TV BRICS, 23.10.25 Brazil has announced the launch of a Reverse Logistics System for Plastic Packaging as part of its National Solid Waste Policy

"Under the new regulations, Brazil aims to recover and recycle 50 per cent of all packaging by 2040, with an interim target of 32 per cent by 2026."

That's a great step in the right direction. 👏👏 We have the necessary technology to do so, might as well use it.

I'm working on a lab values statement for my new (baby) lab! Does anyone have good examples I can look at or advice they'd be curious to share? I have most of mine written but I want to make sure im not missing important concepts.

(I had to mute the video to be able to finish it)

Horrible choice of tie. It gives Italy 1922-1943 and brings out an authoritarian vibe. 10/10 not recommended (for Office).

Carbon dioxide removal is not a current climate solution — we need to change the narrative Drastically reduce emissions first, or carbon dioxide removal will be next to useless.

In recognition of us doing fuck all to reduce emissions, let me remind y'all that carbon dioxide removal (CDR) is useless unless we decarbonize drastically.

I know this has been one of the most widely requested features. Should be in the release on 10/23

The same logic applies. Maintenance, parts, transport, energy distribution, etc. Indirect GHG emissions may be huge depending on how the logistics are (not) planned nationally.

But the only way to know is to actually crunch the numbers and check 🤷‍♂️

The world sure hopes it is negligible 😅

That will depend on the type of power plant. Assuming solar, there will be GHG emissions associated with producing new parts (mining minerals, actually fabricating the parts, etc), transporting them (produced locally? Or shipped across the world?), and so on...

Those indirect emissions can be huge!

Looking forward to seeing the amazing science from your group! 🥳🥳

The calls are officially up for the @researchireland.ie postgrad/postdoc programs! I can sponsor one applicant for each program to work @coreacter.org @ucddublin.bsky.social School of Chemistry. Please reach out if interested, and please share widely!

Se os perfis progressistas (ambientalistas incluídos) engajassem os conteúdos progressistas com o mesmo 'amor' e empenho com que engajam conteúdos da extrema-direita certamente a esquerda seria dominante nas redes.

Impulsionar os adversários e não os companheiros é incrivelmente absurdo.

Congrats Martin! 🎉🥳

I was gonna say

but the author already ruined it for millions of people.

You don’t really think of AI as being bad for the environment

After all, it’s only computers. How could that possibly be so bad

But the truth is, it’s VERY harmful

I keep seeing the Trump-Intel deal called socialism, but there’s a term for this. This parallels what Mussolini did—the Italian state was one of the world’s largest industrial owners while keeping private companies. Nazi Germany did this too. So did Francoist Spain. It’s called state corporatism.

I somehow missed this paper when it came out but it seems exactly what I've been looking out for one of our projects. Thanks for sharing!
