Off topic, but: I often feel that problems related to hard-to-manage waste could be ameliorated by thinking of temporary solutions as "entropy-reducing storage". Especially with recycling — which is currently not cost effective [0] but perhaps could be in the future — we ought to keep the nicely sorted waste separated, and avoid mixing it in with other landfill trash. At a minimum, there's no point in actively increasing the entropy of trash and byproducts. That way, today's landfills could become tomorrow's mines with a lower bar for economic viability.
