Food waste both Domestic and Commercial is a valuable commodity believe it or not. If collected separately it is in great demand as Nutrient rich Compost to condition the soil and reduce or eliminate our dependency on Petro Chemical derived Fertilizers. However when it is not collected separately and mixed in with the general waste the Food Waste fraction is still composted but can not be used in agriculture having been contaminated, has a much lower commercial value and can only be used to reclaim lands and for parks. See Vertal’s MBT plant in the UK on this video as it deals with mixed waste, but the comments made on your Waste Food being used to grow your next meal, relates only to separated Waste Food composting not this MBT type.
