Science Activity : Garbage Enzyme

A friend made a few bottles of garbage enzyme and gave me one last month. It had another month to go before I can use it. The organic waste was banana peel, orange peel and other fruits that she can't recall. It looked like this

2nd month, more or less
On 20/7/2011, it has some bubbles bubbling and some white stuff at the top. it has become a little bit clearer compared from the last time I checked (aiyo, forgot to jot down the date). Hurray! Can't wait to use it for my money plant, which is hanging alone in my bathroom (maybe I should hang another bottle of money plant to keep it company)
more than 3 month

What happened in the bottle?
Bacteria will produce enzyme to help breakdown the fruit. That's why it looked squishy and all mushed up.

Why is making garbage enzyme is the GREEN thing to do?
What is being produced during the enzyme production?
O3 (ozone) + NO3 (nitrate) + CO3 (carbon trioxide)

O3 reduces heavy metals (not the music genre) in clouds. Clouds that trap a lot of heavy metals appear darker so more heat will be trapped on earth. More heat trapped means our earth get hotter (as in temperature and not physical appearance)


the white stuff seems to be forming  on
top of the bottle 

NO3 is good nutrients for plants.

Why do we have to put sugar in the mix?
Sugar is food for the bacteria. Forgetting the sugar is a cruelty towards them.

Why do we have to leave for more than 3 months?
3 months is a reasonable dateline for the bacteria to finish the job. Most of the of the organic waste has been broken down after this period. the liquid is clear with less sign of activity (probably the bacteria are lazing around with nothing to do..hahaha) 

What can we do with the liquid after 3 months?
Fertilizer, of course but some say cleaning agent and much much more. It maybe a good cleaning agent, and deodorant (but the smell.. phew! no thank you)
