GROUNDS / COMMUNITY COMPOSTING
System Design / User Experience / Research
1 week project
An urban composting network connecting communities to farmers through local coffee shops.
COFFEE GRounds as compost
Coffee grounds are an excellent nitrogen source for composting.
Coffee grounds improve soil tilth or structure.
Worms are attracted to coffee and help aerate the soil.
CLOSED LOOP SYSTEM
Symbiotic relationships are established allowing each party to benefit and contribute to the cycle.
Farmers and Coffee Shops sign up for Grounds independently and are matched based on proximity.
The stickers allow coffee shops to customize the compost bins location and size.
Some choose to keep the bins by their dumpsters while others may keep them visible to their patrons.
The stickers inform patrons of where their compost is going and cue farmers to their pick up.
Three coffee shops were interviewed about their composting and trash habits.
None composted their grounds. Two shops did keep their grounds separated from their trash.
