Exactly this. They just burn pretty much everything. I have no idea what the carbon capture situation is like in Japan. But at least they use the waste heat to power municipal baths.

On this note, the exterior of an incinerator in Osaka was 'refurbished' by the Austrian artist Huntertwasser, who was certainly an interesting person.

If you're ever in Vienna, there is a museum of his design that is worth visiting - it's quite unlike anything I've visited before/since

Interesting. And how do they handle the toxic fumes?

They breath then, that's how...

That is an active area of research.

That's surprising to me since they have one of the best average air quality scores of any country (that's avaiable with gmaps).
