This is literally the most intriguing thing in my life right now. What a tease. Does anyone have insight into why Italian garbage is less safe?

Hmm. I was under the impression that burning garbage is different in that you are burning carbon that is already in play in the carbon cycle system - unlike burning coal, which without human intervention would never be introduced into the environment at such a rapid pace. I could be wrong! I was disappointed by the lack of an explanation, or even links to background on the science of this process. Just a puff/fluff p…

It would really depend on what is being burnt. If it is primarily food waste, paper products, natural fibers, wood, etc.. then yeah; all of that carbon was already "in the system". If they are burning lots of garbage made from petrochemicals then that garbage is basically just another fossil fuel. As I understand it, the real issue with "clean coal" is not the soot but rather the CO2. Depending on what this garbage a…

I found a case study about Oslo's waste management strategy: http://www.c40cities.org/c40cities/oslo/city_case_studies/wa...

The study emphasizes their focus on composting for food products and recycling everything else, so a minimum of waste needs to be incinerated or dumped. Also, Oslo closed their landfill in 2007, and it seems they burn the residual gasses (methane?) for electricity, if not burning all of their old trash. The report focuses on home recycling requirements, but does not mention commercial or industrial waste, which are by far larger generators of waste.

So, it seems likely that the incinerated waste is not "in-system".

The Mafia. They control some of the Italian garbage and you are not sure what the garbage actually contain.

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

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.

It's better than landfill without methane recovery, greenhouse gas wise.

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

Being a tropical country, India does not need much of indoor heating. Fine option for heating water.

Or process heat for industry, that's how it is used in my home town.

Or desalinating water. India needs clean water, no?

Not really, they just drink it from the river.
