Hello, I've just begun PhD research into the use of on site composting of human waste and its use as a fertiliser. If anybody is working in the same area I would be glad to hear from them. Also, would anyone know the address, E-mail or otherwise, of the 'International Reference Centre for Waste Disposal'? Thanks.
