Children picking up litter from a park

Enter the 2025 Litter Poster Competition

Published: 19/03/2025

The Parks Trust are proud to launch the 2025 litter poster competition in partnership with Milton Keynes City Council. We are asking 5-11-year-olds who attend a Primary School in Milton Keynes to unleash their creativity and design a poster that encourages people to stop littering across the city.

The winning design will be displayed in the parks, in local parish council facilities and on social media. Winners will receive a set of 10 litter pickers for their school, and a free Outdoor Learning session with The Parks Trust if your school can accommodate it. The winning artist will also receive a goodie bag. 

How to enter

  • A4 size
  • Designs should be eye-catching and easy to understand

Top tips

  • Content of images – Think about the benefits of taking litter home and the problems litter causes
  • Colours – bright colours will attract more than black and white
  • Drawings – make sure they are clear. It is important that the images are your own and not traced from a book etc. You can use digital illustrations or photos but they must be your own. 
  • If you are using text, think about your language – is it simple and short? Make sure it is easy to understand.

Entries must be submitted by the closing date of Friday 25th April at 5pm. Please read the competition terms and conditions before entering. All entries will be judged and the shortlisted finalists will go to a public vote on Tuesday 29th April to help us decide the overall winner.

We can't wait to see your entries. Good luck!
