So you believe that it is more energy efficient for a ton of compost to be moved by humans than by a single truck making one trip? What about all of the oil it takes to generate the food to feed the humans who move the compost? I don't have time to do the math at the moment but I hope someone else does. That sounds dubious at best.
How much extra food does it take? It's not that strenuous to use a bike, just takes time. Also, if the compost is used to grow food, it doesn't take much oil to feed the biker!
