I was interested to see more ways that larger scale sewage treatment facilities are being utilised for recycling and greener purposes, especially after my post regarding the recycling of CD’s last month.
A Sewage Treatment facility in Berkshire is being used to create phosphate thanks to the unique make up of the waste water being sent to it by residents and workers.
A report earlier this month in the Daily Mail claims that:
“A new £2million sewage treatment facility is turning our waste into super fertiliser that could help secure future global food supplies.”
Reading the story in more detail it seems the plant utilises the phosphorus from the sewage to create fertilizer than can be used by crop growers here in the UK.
At present we (the UK) import 38 tonnes of fertilizer a year from other countries, so there are obviously benefits to the economy of using the facility this way.
Each year 150 tonnes of the special fertilizer will be created by the plant based in Slough . The chemical is said to be critical in the growth of crops, but it is thought that demand will overtake supply possibilities around the year 2030 as stock of the typically mined substabce starts to decline. This renewable way of creating the phosphate is therefore going to be welcomed by the agriculture industry, for whom a decline in supply would likely effect greatly.
The full report completed on the 5th November – It’s viagra for plants – can be found on the Daily Mail website.
