Re: [biofuelwatch] Digest Number 1686





Sarah,

the basic problem about using any crop residue or waste for biofuel is that this removes the plant "waste" from the natural nutrient cycling system.

If one remembers that the plant biomass has been grown using mainly artificial, fossil fuel based fertilisers, basically all that is happening is that the fossil fuel is being converted - in an inefficient manner - into energy, through tapping into the latent energy of the plant biomass.

What should be happening is that the plant waste should be being composted and returned to the fields to close the nutrient cycle.

All of teh talk of using switchgrass, bagasse and any other crop stover is basically a symptom of open cycle, opportunistic thinking which fails to consider the holistic nutrient cycle which we used to rely on! Which is one of the reasons we are in the mess we are in...

be well
Glenn

Biofuels are a wide range of fuels which are in some way derived from biomass.

Your idea?
