Car Tyres May Purify Wastewater in Future. Pixabay

Rubber granulate made from end-of-life car tyres may in future lend itself to applications such as wastewater treatment, say researchers.

A Finnish team has demonstrated that the granulate processed from used car tyres is capable of acting as biofilter material in sewage treatment.

The project, carried out by Finnish Tyre Recycling Ltd and Apila Group Oy at Heinola sewage works, showed that tyre rubber granulate is capable of effectively removing nitrogen and phosphorus from wastewater.

The granulate offers a large surface area for the biofilm to grow on and significantly retains, in particular, phosphorus, thanks to the iron contained in the granulate.

“No leaching of harmful substances from the tyre granulate to the soil or water was detected, but the use of granulate for sewage treatment requires an environmental permit,” explained Risto Tuominen, managing director of Finnish Tyre Recycling.

“We have also decided to test tyre granulate in the treatment of industrial wastewater. Other interesting applications include the treatment of run-off water from agriculture, peat production and forestry,” added Tuominen.

There is a lot of potential in tyre rubber granulate as soon as the hesitation to use it dissipates, said specialist Sanni Pisto from Apila Group (IANS)



7th of December 1949, the Armed Force Flag Day

Since the 7th of December 1949, the Armed Forces Flag Day has been observed in India, annually. This one day is dedicated towards collection of funds from the citizens of India for the welfare of the ‘Indian Armed Forces personnel’. It has become a tradition to pay respect to the people who have served in the army, Navy and Airforce, on this day.

“The idea behind observing a Flag Day was to distribute small flags to the general population and in return collect donations.” The color-scheme of the flag is very similar to the ones used by fellow Commonwealth members like Cyprus, Kenya and Nigeria. The Flag Day signifies that it is the responsibility of the citizens of India to take care of the families and dependents of the armed forces personnel who fight for the country.
