Warren Central School students were able to examine oils, carbon, the steel tyre reinforcing and beading that are recovered from the processed tyres, and learn how the oil can be refined into petrol, diesel, jet fuel and other petroleum products.

"We would like to encourage other schools to visit particularly any from the Dubbo area because we recognise getting the recycling message to the next generation is very important," Mr Bayley said.

Warren Central teacher Abdullah Zayied said the school visit was instructional as the children were studying resource management and recycling and it was an opportunity to see how it all works in practice.

"Naturally, we had to be aware the plant is an industrial workplace so we did a thorough risk assessment prior to the visit to minimise any danger," Mr Zayied said.

Mr Bayley said recycling was vitally important for the future and particularly when it came to items like old tyres that were such an environmental problem, as they will last for over 500 years.

The carbon is used in a range of products from printers' ink to cosmetics and the steel can be used for scrap or for new tyres.
