As biodegradable waste contains a lot of water, I was wondering how much mass reduction I can achieve by exposing it to the sun (by evaporating some of the contained water).

On a sunny day in March (Belgium), I weighed these fruit peels (I had just consumed the fruit):

66 grams

Exposing it to sun & air:

After 7 hours, 24 grams left:

So we lost 42 grams, almost 2/3 of the original mass.

For those of you having to pay for their household biodegradable waste processing by the kilo, it might be something to look into.

I’ll have to figure out if this is something practical & that scales easily, or not.
