Collaborating with Dr. Love-Ese Chile and her team at Regenerative Waste Labs, I was tasked to translate this technical paper on composting biodegradable plastics into an educational sign for the general public.

These signs were to be placed in front of compost bins located in community urban farms, where Dr. Chile's team were monitoring rates of degradation of different types of materials as an educational project.

These materials included fruit peels and manufactured compostable products, and the sign to needed to explain the differences between the types of compost material and how they degrade. After a few rounds of iteration and collaborative sessions, we sent the signs off to the printers!


How do compostable products break down? One side explains how a banana peel breaks down, with all three types of degradation happening all at once (physical, chemical, biodegradation). The other side explains that a biodegradable plastic cup needs some extra help.

The final sign

Initial layout ideas.

First version in production

The first step was to understand the content. After determining the content of the poster over a few co-creation sessions, I sketched out some initial layout ideas. Then, I create the first "proper" version.

Signage outside the urban farm, along with a chalk sign: City Farmer

After the project was over, the sign gets another life: greeting people walking by the urban farm!
