What is it and who is it for?
Venues with organic waste streams they can consistently expect and plan for can retrieve and maximise the value from those waste streams by transforming and repurposing them into energy, fertilisers, water, or even new foods.
How could it work?
- Specific types of organic waste (e.g. coffee grounds) can directly be used for e.g. mushroom cultivation
- Different types of organic waste can be repurposed into biogas, digestate, electricity, or event water using either
- Portable units or
- Built-in systems at fixed locations
- Fast-composters can enable the quick transformation of organic waste into compost that urban farmers can use right away.
Existing solutions include:
- The Waste Transformers (transforming organic waste into value)
- Alchemia Nova (transforming organic waste into biogas)
- The Waste2Food platform (recovering protein resources from organic waste)
- RotterZwam (turning coffee grounds into mushrooms)
- GroCycle (turning coffee grounds into mushrooms)
- Are there examples of buildings, hotels, or venues that have successfully set up closed-loop systems using organic waste?
- How can we ensure demand for the outputs if e.g. the quantities produced exceed the needs of a particular venue?
- What would be a good place to start?
- What needs to happen at the venue level to make this solution at success? Who needs to be on board?
