sadly I feel most people would not like the idea of grinding up your bones for fertilizer. How ever my father does want to be dug into his own compost heap. No idea how I'll get that past the local council !!
I'll get him to put it in his will for a posthumous ( pro humus ) giggle !!

Seriously though I think we need a serious effort in place to stop the flushing of NPK down the loo. Be that home composting or centralized re-cycling. But who here will want to deal with their own "waste" ?

Could be combined with methane production to solve a cooking fuel issue.

Just had a thought. When it comes to recycling humans and human waste, we could have a massive problem with persistent pharmaceuticals which could build up in the consumers of the produce. Diclofenac is but one example of a persistent drug that kills vultures.

It seems that if we were to recycle people and human waste that we would become victims of the chemical industry.
