Applying the same “modus operandi” as Precious Plastic in order to repurpose tons of wasted coffee grounds.
– OPEN SOURCE;
– Machines made from basic materials, affordable & easy to build;
– Modular and scalable;
– Fun
Building a set of machines which make the extraction of biofuel, from used coffee grounds, possible.
Residual waste can then be turned into coffee briquettes/pellets which can be used for heating or cooking purposes.
Used coffee grounds could possibly provide energy to power a Precious Plastic V3.0 container/workshop.
Let’s apply the lessons learned and repurpose used coffee grounds so they don’t end in a landfill.
That’s cool
I know that you can mix egg shells and coffee grinds to make an excellent fertilizer, but one project I have been interested for a while is to use food leftovers to create Methane gas using a home-made biodigester https://energiacasera.wordpress.com/2009/11/19/biodigestor-casero-de-bidon/
Yes, bio-bean is a company on an industrial level for big cities like Melbourne [and London]
Precious Coffee could be implemented in big villages or small cities. Using coffee from the biggest coffee shops and office spaces. Not really on a household level.
The biofuel part of the process may be complex, but the briquettes/pellets part not so much, I think.
Ooh, I like this. I’m guessing you are targeting coffee shops rather than individual consumers?
Most of my hippy pals who have coffee grinds to dispose of put them in the compost/ wormeries, and one dedicated gem of a person keeps his for his orchard as they are acidic and especially good for fruit trees apparently. (Who knew?).
Please check bio-bean.
It’s a company based in London. Unfortunately their technics are not open sourced I’m afraid. However, it’s a really good starting point.
