Living on biomass only: a thought experiment

  • by

Let’s suppose we design a society to live on biomass only. What sources do we have available and how are we going to divide the uses of that biomass to get the most out of it? And if there is a lot of carbon in the atmosphere will we still need to carbon compensate and sequester even if we stop using fossil fuels?

First of all it is only excess biomass we are talking about: food waste, wood not used for building or firewood. And waste not composted. The diagram below shows one feasible scenario.

The top section is for dry waste, the sections below for wet.
