It's the Compost

[from longer article at www.Permacultureactivist.net]
"Much interest of late has gone towards the process of converting waste cooking oils into biodiesel. While this is interesting and creative, it seems inherently limited in its applications, primarily because of the relative scarcity of the source material. Nothing like a sufficient quantity of spent cooking fat is available to provide adequate transport energy for the entire population, even at vastly reduced levels of energy use. Also, the production of industrial cooking oils is primarily monocultural and inherently devastating to enormous areas of the planet. Biologically, production of oils requires a more complex and less efficient energy pathway than plant production of cellulose and ligneous material.

"There will always be many hundreds, if not thousands of times more woody material than oil produced. In addition to the basic phytochemistry, there is the geographic argument: many millions of acres of land are unsuitable for arable crops, are degraded forest of low yield, or are wastelands wrecked by agriculture­ or toxic chemicals. We need technologies for deriving economic yield from the rehabilitation of these lands. We also need simple technologies to break the monopoly of the fossil fuel industries.

"It was the genius of Jean Pain to grasp the essential problem of the age and throw himself into finding simple and appropriate technical solutions for it (even if, by his admission, he did not know all of what he would do at the outset). That these solutions find their most efficient application at a modest and very local scale is a boon to the world and has everything to do with Pain’s original intent. The social and labor arrangements, capital financing, and technology­ required to yield useful and commercially valuable energy and fertilizer for individual and community-scale application from restorative forestry are within the reach of large numbers of people and groups throughout the world.

"What is needed now is for significant numbers of people to realize and take responsibility for our continued use of liquid fuels in transport, energy for domestic heating and hot water, and to realize that the stable and successful transition to a sustainable economy requires us to develop locally controlled and biological sources for these energies, based on simple, widely available and applicable technologies."
