Plastics, Glass & Other Useful Stuff

It is vital that we recycle correctly. If a recycling bin is contaminated with food waste, liquids or other non-recyclable materials the entire bin will go to landfill.

There is a growing number of products that can be made from recycled materials, from fleece jumpers, carpet and wheelie bins (plastic), to road-base (glass), airplane parts and bicycle frames (aluminium cans).

Producing these products from recycled materials rather than fossil fuels uses up to 30% less energy and saves a considerable amount of water.

Recycling also saves landfill space and prevents garbage, like plastic, from ending up in oceans and waterways.

How To Recycle on Campus

      • Use the yellow recycling bins for the recycling of glass bottles, aluminium cans and hard plastics* (such empty drink bottles and food containers). *If the plastic container holds its shape when crumpled, and/or would hold liquid, then that item is suitable for recycling.
      • Scrape all excess food and liquid from containers and bottles into an organics or landfill bin. The machinery that processes recyclables can tolerate a minimal amount of food waste - but not much.
      • Rinse items if the facilities are available.
      • Remove lids from plastic bottles before recycling as the two components are usually made from different materials and if left on, the tops trap air inside the bottle which means it can’t be compressed when it is baled for recycling.
      • If possible, throw paper and cardboard into a blue paper recycling bin. If there is no paper bin around, they can go in the yellow bin.

What Can't Go in the Yellow Recycling Bin

      • Plastic document sleeves and binding covers.  Throw these in the red general waste bin.
      • Plastic computer parts, such as keyboards. Dispose of these through the e-waste stream.
      • Soft plastics, such as shopping bags and plastic wrap. Throw these in the general waste bin or recycle them through a soft plastics bin at a supermarket.
      • Recyclables inside a plastic bag.
      • Excessively dirty items or bottles with liquid inside.

What the Numbers and Symbols on Plastic Mean

Plastic bottles and most other plastic items include a triangle with a number from 1 to 7. This is not a recycling symbol but rather a Plastic Identification Code that tells manufacturers what type of plastic the item is made from.

All rigid plastics labelled from 1 – 6 can be put in the recycling bin. However lightweight polystyrene, such as meat trays, packaging (including foam packing 'peanuts') and hot drink cups cannot be recycled.
