摘要
At least one nutrient-rich substance and/or waste product is added to the effluent. A method for processing effluent liquid or sludge in order to produce fertiliser, comprises increasing the nutrient content of the liquid or sludge by adding one or more nutrient-rich substances or products (preferably natural ones) and/or nutrient-rich waste products. An Independent claim is also included for fertiliser produced by this method.
