The potential eco-synergetic effects of using two waste flowsfor the substitution of mineral fertilisers is assessed from nutrient and environmental points of view. The two wastes are: composted organic municipal waste (slow release of nutrients) and nitrate polluted water (rapid nitrogen release).Catalonia is selected as a representative Mediterranean area of study. Macro-data at county level was used for the calculations, geographic information system, for the illustrations, and IPCC impact factors, for the environmental quantification. Compost and polluted water are able to supply 35-50% of the nutrient demand of Catalan horticulture production (330,000 tons of horticulture products per year), leading to reduction of 46% of the global warming potential of mineral fertiliser production.Moremineral fertilisersare saved in urban and agriculture intensive areas.
