Thames Water to produce fertiliser from waste

October 21, 2010 at 4:48 am

Thames Water has announced that it will be starting up a new process of producing eco-friendly fertiliser from sewage. The process will take place in a waste water facility in Slough, and follows on from a successful experiment in North America.

The process involves recycling excess nutrients in the water into environmentally-safe fertiliser. It reuses natural resources as well as creating a product that is safe for the environment, leading many to dub it the perfect solution.

The Slough plant has been running a pilot scheme since March, and it will now go into full-scale production of the fertiliser. Thames Water will partner with Ostara Nutrient Recovery Technologies, a Canadian firm, and the facility should be up and running by the middle of 2011. The project will cost in the region of £2 million.

The process works by removing struvite from sewage which contains ammonia and phosphorus, and then converting this into natural fertiliser. This will be the first time the process has taken place in Europe. The plant will produce 150 tonnes of fertiliser a year, which will go by the name of Crystal Green and will be sold around the country.

On top of the benefits of the renewable product, Thames Water will also be saving £130,000 to £200,000 a year in chemical dosing costs which are necessary to clean up the build-up of struvite.

Reserves of phosphorus are running out around the world, with some experts predicting that mineral sources could run out completely in the next 30 years. This new technique could therefore become a very important way to produce a renewable solution to the problem.

  1. Sewage treatment system sludge says:

    Yes, sewage sludge is turned into fertiliser in North America and there have been many Court Actions as a result. Sewage contains viruses, bacteria and prions (Altzheimers disease is a prion), some of which are almost impossible to kill and these have caused illness and death. There are American websites devoted to it. The Canadian Health Authority even has a name for the disease, ‘Sewage Sludge Disease’. Of course we are told that there is no danger involved, after all, isn’t that what they said about feeding animal by-products to cattle – before Mad Cow Disease evolved?

  2. Sewage fertiliser is NOT harmless says:

    Alzheimer’s Disease (AD) has been identified by scientists as a prion disease. There are nearly a million victims of AD in the UK excreting infectious prions to sewers, where the wastewater treatment process reconcentrates the prions in the sewage sludge that Thames Water intends to turn into ‘safe’ fertilizer. No sewage treatment process inactivates prions – they are practically indestructible. The wastewater treatment process reconcentrates the infectious prions in the sewage sludge.

    It is madness.
