The theme for the 2025 International Compost Awareness Week (ICAW) Poster Contest is "Sustainable Communities Begin with Compost!".

My concept for this design draws inspiration from Andy Griffiths' and Terry Denton's Treehouse children's book series. The focal point of the design is a large treehouse, inhabited by a community of personified animals living in harmony with each other and their environment. These animals are all working together to care for the tree that provides their home so they can continue to grow and thrive together. The roots of the tree are growing amongst composted soil, depicting that the community is thriving from the provided nutrients from the act of composting.
