the current process of waste management is wasting valuable nutrientswasting valuable nutrients
• Compostable, clean organic material which contains the nutrients necessary for the production of food is currently lost to landfill
• Plants need between 60 to 90 nutrients, minerals and trace elements to be healthy
• Chemical fertiliser only contains a few of these
