Is There Enough Biomass to Fuel the World? Part I
How much biomass is produced each year and how much can we sustainably harvest? In the first part of this series, we find that the annual global production of land-based biomass is 50 billion tons, of which roughly 8 billion tons of biomass can be sustainably harvested each year. This is determined by dividing biomass into four distinct groups suitable for energy production: wood, agriculture, food waste and manure. For each group, the amount of annual ‘production’ and the amount suitable for sustainable ‘harvest’ is determined, adhering to the ‘food, feed, fiber first’ principle.
