Tokyo government has switched from fossil fuel to biomass energy to supply around 80 percent of electricity in its Shinjuku Ward headquarters, as part of efforts to achieve net zero carbon dioxide emissions in the metropolis by 2050.

That's a good start, local govt set example for the rest of nation. While central govt still doing things unchanged.

Hitachi Zosen purchases energy produced by waste power generation at incineration plants within and outside Tokyo, supplying the biomass portion to the city government.

There is a "biomass portion" that can be separated when burning garbage and running thermal power generation off the heat?

I do know you can make electricity from biomass like wood pellets, but you normally don't burn them at garbage incinerators.

Although what TMG is trying to accomplish is clearly admirable, it's a disingenuous claim. You cannot buy some of the electricity produced jointly from renewable/non-renewable sources and claim that your electricity is only from the renewable portion.

At most they can claim that around 40% it does (roughly corresponding to the biomass portion of waste in these plants) which is still much better than nearly everyone else.

Why not just convert all available incinerators to waste to steam power plants. Burning waste can boil water to create steam energy just like a nuclear power plant. But waste to steam power plants are much safer and with filtered smoke stacks it is a whole lot cleaner too.

Cheaper and cleaner. Somebody has to lead the way if the USA won't. Bravo, Japan!
