An indoor pig breeding unit has installed a new slurry treatment system which promises gains in storage, handling and nutrient value.A seaweed-based prebiotic treatment is dramatically reducing the volume of slurry to be stored and handled on a South West pig farm. The treatment results in water that - subject to permit - will be clean enough to be returned directly to watercourses.The process, which is being used for cleaning waste water elsewhere in Europe, also produces an added-value solid product that can be used as a natural fertiliser with highly available nutrients, or as a feedstock for anaerobic digestion (AD). This willhelp the farm - the first in the UK to use the technology for livestock slurry treatment - in its overall aim to build a circular farm economy.
