How about stop making planned obsolence products? How about not charging outrageous prices when their computers need repair?

New comment by alexandrehtrb in "Ask HN: Why are electronics still so unrecyclable?"

> I have some notes on a semiconductor fabrication process with just sustainable inputs: Ethyl Lactate, Lignin-Vitrimer, Nitrogen, CO2, Laser-induced Graphene, A-CNT, PCLP Photo-cleavable Lignin Polymer, Hexyl Cellulose

Yeah, I was thinking of something like that. If there are fewer chemical components, recycling gets easier.

Ask HN: Why are electronics still so unrecyclable?

alexandrehtrb — Wed, 11 Feb 2026 15:12:53 +0000

I was wondering why electronics and computer parts are so unrecyclable (is there a better word for that?).

From what I searched, only a small percentage of electronics are recycled and those that do, are through chemical processes. Electronics today use plastics and special metals, and extracting them isn't straightforward, because requires energy and big acid digestors.

Is there some kind of initiative on this area, on using other materials or designing chips and boards to be more recyclable or reusable?

We shouldn't post politics news on Hacker News unless they are tech-related... if we allow this, it will grow worse through time. I am here to read tech content, not politics.

Most reflection usage is for JSON (de)serialization and for that you can use source generators, which also offer better performance.
