> what is possibly the greenest power plant in the world
That's a bold claim with no evidence. They're burning trash. How could that possibly be the greenest power plant in the world?
Dane here. I agree strongly.
The plant is likely to be burning imported wood pellets as well, because its capacity is way above the amount of available waste[0]. So-called "biofuel". It's quite controversial, to say the least[1]. This is similar to what Drax (largest CO2 emitter in the UK) did to wiggle around the phase-out of coal and to get in on those subsidies for green energy, which apparently includes importing wood from forests in the US, because some clever lobbyists has ensured it qualifies as "green".

I just recently happened across an investment brochure for wood pellets (produced in Germany). The projected returns are pretty good, and the brochure definitely marketed them as "green" (renewable and carbon-neutral (if you plant enough new trees), local (if you consume them locally)).
I don't read Danish, but surely the power company will at some point be able to provide information on what percentage of their fuel (in the last year) was municipal waste and what part was e.g. "biofuel". Speculating just based on the amount of waste produced in Copenhagen (or Denmark) and the power plant's capacity doesn't appear very fruitful to me, because if your plant is capable of handling municipal waste and has more capacity than available waste, you could just as well import waste from other countries and turn that into electricity. (Depending on distance, burning pellets may of course be cheaper, as they have more energy per cubic meter. But pellets cost money, and treating waste for others makes money)
It's covered in grass, albeit artificial. The ski course is green in summer.
"That’s right. Last weekend in Copenhagen, an 8-year dream was realized when the first paying skiers took their runs down a one-third-mile course, wrapping around what is possibly the greenest power plant in the world."
"A hybrid between a building and a landscape, the huge glass and mirrored structure contains planters covering the façade in a checkerboard pattern that might one day give the illusion of a GREEN mountain from every direction"
If anyone knows where to find more technical details about how this plant works, and what makes it "the greenest power plant in the world", I would be curious to take a look.
The plant is located very close to downtown Copenhagen, and there is no ash issue.

Personally I've looked what is slag consist of as it doesn't seem like it could be very green, but so far looks like good idea.
