About the innovation

Why did you create this innovation?

By composting you can reduce the amount of waste sent to landfill.

What does your innovation look like in practice?

Landfills seal rubbish in airtight spaces so air cannot get to organic waste. This means it decomposes anaerobically (without oxygen) and creates powerful greenhouse gases, in particular methane which contributes to global warming and climate change.

How has it been spreading?

But sending organic waste—a chaotic jumble of yard material and discarded food—to a landfill takes up a lot of space. More troublesome, however, is that when organic waste is buried, it decomposes under oxygen-free, or anaerobic, conditions, producing gases that pollute the atmosphere. The decomposition is driven by microbes that grow in the absence of oxygen. We took a film video sequence about it ,with the interaction of the whole class.

If I want to try it, what should I do?

What do you need?
banana peels, egg shells, coffee residue, water, blender

1. Place everything in the blender,  mix it up for a minute or three. And you’re done!
