Untapped resource: coffee grounds. Turning waste into a resource for natural dyeing.
I’m thinking about the food waste in my local area in particular the university I tutor at and it’s local coffee shops. Coffee ground waste is immense, we only have to think about how much coffee the population consumes and then imagine this on a global scale.
The cafe upstairs from my workplace uses kilos and kilos of coffee each day. How can we divert this and use this resource? In one day we reclaimed a FIFTEEN litre bucket full of used grounds that would just go into landfill and won’t be composted. Instead we are trying to divert a small amount of this waste in a local trial to see haw we can use it as a natural fabric dye.
How could we upscale this on a larger scale? Utilise the dye qualities and then responsibly compost afterwards?
