This article is a continuation of our previous blog about the benefits and strengths of the solution.  Hereafter we look at the environmental benefits, and provide an overall summary of the benefits of the solution in terms of pig manure treatment.

Environmental benefits

– Solugen runs on electricity. The system is energy-efficient (30 kWh are enough to treat one m3 of slurry) and includes a continuously operating heat recovery process for the treatment of the liquid fraction of the manure.

– Drastic reduction of manure spreading operations, which limits the use of fossil fuels for manure transport and spreading.  From the manure Solugen extracts a solid fraction, biological fertilizers in liquid form, and a high proportion of pure water.

– Reduction of 90 to 95% of the greenhouse gases normally emitted during manure storage and spreading operations. A Solugen system that treats 10,000m3 of slurry per year results in an annual reduction of 572 t CO2 eq.

– Reduction of greenhouse gases emitted by manure transport and spreading vehicles

– By considerably reducing spreading operations, the risks of eutrophication of watercourses and water bodies are significantly reduced.

– Following the liquid-solid separation which is the initial phase of manure treatment, 85% of the phosphorus contained in the manure is found back in the solid fraction. This makes the management of this nutrient much easier, especially in agricultural areas with phosphorus-saturated soils.

– Solugen can extract pure water up to 84% of the treated slurry volume. This water can be used for cleaning livestock facilities, for example, or can be discharged into watersheds without any negative impact on the environment.

Environmental co-benefits

In addition, the Solugen solution offers environmental co-benefits such as :

  • Reduced risk of deterioration of drinking water sources,
  • Reduction of NH3, VOCs (volatile organic compounds) and H2S emissions,
  • Alternative solution to replace part of the mineral phosphorus used in agriculture. It should be noted that sources of mineral phosphorus are limited and show a deficiency in the medium term. The end of mineral phosphorus could create an agricultural crisis.
  • Risks of manure spills when manure pits are full (impact of rainfalls for example)

Preservation of biodiversity

  • Reduction of high levels of phosphorus saturation in the soil reducing :

o Degradation of watercourses through eutrophication

o Groundwater pollution

  • Reducing the risk of over-application of nitrogen and phosphorus.

● Moving towards an eco responsible production: increased value of manure as a fertilizer in terms of timing, content and uniformity of application, thus reducing the need for mineral fertilizers to be applied to crops
