@[email protected] you're presumably joking about the feasibility of getting some of the energy wasted on food & plastic back out again.
But this is a good article on how renewable hydrocarbons can be used for energy. Of course, modern energy use would probably exceed the forage capacity or new growth wood.
What energy is wasted? The energy is still there, it's just a bit annoying to burn (lots of big waxy molecules) so this is a method that breaks it down chemically and makes it easier to burn.
Biomass as fuel is a solution looking for a problem, and trades soil health for nothing compared to electrification. Dumping biomass in deep anoxic lakes might at least reduce the quantity of GHG emitted as opposed to being 'neutral'. Get some solar panels and wind generators and get hydrogen with hydrolysis (and then turn that into whatever you want), or nuclear (Hello China).
By energy wasted on food and trash I mean the hydrogen & energy (both generally from fossil fuels) that go into a lot of the fertilizer which is used in industrial agriculture. All of the energy which goes into plastic manufacturing: fossil fuel feedstocks, cellulose and other stuff going into it, to the transport of supplies & the energy use of everything.
Yeah effective composting is a good way of doing that. I have a compost bin.
