Oslo is turning garbage into energy and is running out of garbage

Re: Oslo is turning garbage into energy and is running out of garbage
#2Oslo is powering their city by putting black ash into the air, which absorbs heat from sunlight, slightly increasing the amount of energy in all of our environmental systems. The place is powered by externalities, just like China. This solution is no better than coal-generated electricity, and this feel-good article is no more useful than clean-coal articles.

#3I always thought burning garbage is really bad for the environment. Aren't there dangerous chemicals that are released if the garbage is not incinerated?

It seems that the garbage is sorted through before they burned it.

At least in the US, a modern incinerator produces cleaner exhaust gases than a power plant does. This is because the air quality restrictions are quite tight, and building an incinerator from the ground up with those restrictions in mind results in exhaust flues with filters to catalyze by products into non-aerosols.
That said, providing heat is the best use for this since even low grade heat (100 - 150 degrees C) is usable for heating buildings and water for washing etc. But you can't pull a lot of electricity out of it with steam turbines.

Don't some of the modern systems have processes that mitigate the released ash?
I found their recycling systems to be even more impressive sounding than the garbage incineration

My understanding is that the garbage would be burnt anyway so better use it for heating.

#8Can you please come to India and help us. We need this very badly.

As others have noted, you can sort out the worst garbage and install filters, and modern filters are very good.
It’s still worse for the air than putting the garbage in landfills, but landfills have their problems too.

That was it came to my mind when I read the article!: "Why not expand to India?"
