I hate typing this because it gives Nestle the slightest shred of credit. Their pods are aluminum and recyclable. Keurig k-cups started off as non-recyclable plastic but have now switched to some kind of, apparently, recyclable plastic…supposedly. Doesn’t make the use of pods much better but it’s not nothing.
To expand on this Have you considered Matrix? It’s like IRC but encrypted AND includes a bridge to IRC so you can have the best of both worlds. https://matrix.org/ The most popular client here https://element.io/ though there are many others.
