So you reckon you're clean and green? But what about your bodily waste? Who takes care of that. Alan Leckie from Forest Research in Christchurch has come up with a plan to use our solid waste (euuurghhhhh!) as a fertiliser for trees, effectively turning our waste from a difficult problem into a useful resource. Trees also help to remove the most environmentally harmful elements from the biosolids which is just another reason that they are so important!! Follow that turd!
