<p>A process for producing a nutrient rich material, the process comprising dewatering dairy waste to produce a sludge having a solids content of between 20 % and 30 % by weight. Optionally, the process includes the step of further drying the sludge to approximately 90 % solids and optionally mixing the dried sludge with a matrix material comprising organic and/or inorganic compounds to produce a nutrient base fertiliser. The invention also relates to a process for producing a growing medium by mixing the nutrient rich material with matrix material comprising peat, composted bark and lignite and composting the resulting mixture.</p> |
