I come from Japan, currently studying Education Policy and International Development at the University of Bristol. I wanted to try something out myself addressing environmental issues while I study how to incorporate sustainability in education.
My challenge
I would like to try fitting my one month waste in two jars. (food/other waste)

I had my food waste in the freezer to prevent it from rotting. 

Then an idea came up in my mind that maybe defrosting the waste would help to shrink the whole thing, so I decided to do it… and it worked!

The jar full of food waste became half of the amount. 

This may not be reducing the food waste it self, but I think it is worth doing since I can reduce the plastic bag use for taking out the trash. 

I also find this quite easy and handy, because by freezing the food waste I do not have to worry about the smell. (Which was sometimes annoying when I was keeping it in the bin)

I might be able to continue the freezing and defrosting routine even after the cChallenge period is over.
