From tankered waste and trade effluent services to our biosolid fertiliser for agriculture and land reclamation, we have your business waste needs covered
Recycling biosolids back to the land makes some savings in environmental impact both from mineral fertiliser production, transport to the farm gate and its final application.
Recycling biosolids to agricultural soils has an important role in replacing the loss of organic matter that can arise from intensive arable farming where there is no alternative organic input. A reduction in organic matter can lead to increases in soil erosion which can contribute to the silting of watercourses.
The production of Nitrogen fertilisers requires large quantities of energy. The manufacture of one tonne of nitrogen fertiliser in a modern process produces about 2.2 tonnes of carbon dioxide the most important contributor to climatic change.
Production of phosphate fertiliser typically requires both mining and chemical processing both of which can have significant environmental impact. Phosphate fertiliser is mainly produced in Florida and Morocco incurring substantial transportation with the subsequent further emission of climate change gases.
The impacts of mining and processing also apply to the trace elements that biosolid supplies. This particularly applies to Sulphur that increasingly has to be applied as a fertiliser as natural deposition decreases.
All these impacts can be reduced by using biosolids.
