We are working with LitterLotto to encourage everybody to bin their litter responsibly.

To take part, download the free LitterLotto app download from the App store or Google Play.

Use the app to take a photo every time you put your rubbish in a street bin. Every piece of litter you bin and photograph counts as an entry, so the more you bin, the higher your chance of winning.

There’s a weekly prize of £1,000 for all participants in the UK. In Cambridge, there are also two monthly prizes: £100 cash, and a £50 Love Cambridge gift card courtesy of Cambridge BID.

Your photo must include:

• the mouth of the bin you’re posting into
• the litter you’re binning
• your hand, or a litter picker

Any litter that you would dispose of ‘on the go’ counts – for example, food wrappers, cigarette ends, or bagged dog poo. Household waste such as shampoo bottles, loo roll tubes, and teabags do not count.

If you cheat, LitterLotto will recognise it and none of your entries will count. This includes taking multiple photos of the same bit of rubbish.

Putting rubbish on top of or next to a bin will not count, nor will using a domestic household bin.

The official LitterLotto rules explain eligibility and restrictions in full.
