The smallest saving occurs if the heat comes from a gas-fired CHP plant, i.e. when it is a by-product of electricity generation. "We should only build new district heating networks in regions where we know we can connect sufficient geothermal sources in future" But heating networks have disadvantages and limitations too.
The process, which is expected to turn at least a third of the trash into useable electricity, isn't exactly the best thing for the environment on account of all the CO2 it'll release, but it'll at least put a nice, big dent in the landfills and illegal dumps that have been building up in Shenzhen. One of these landfills actually killed dozens of people last year when it unexpectedly
