14 Is there enough Biomass! Current liquid fuel required (petrol + diesel) = 60 million ton/year Rising at >10%/year 300 million ton biomass waste 75 million ton biofuel/year 30 million Ha marginal land 300 million ton biomass 75 million ton fuel/year Competition with Animal Feed industry Is this enough, say in year 2050? BIOMASS will stagnate with time. Besides, there is need to find replacement for diesel WHAT NEXT?
