Start with what you already have lying around your house.  Your garbage.  You might be a little hesitant on going through your household trash but if you really think about it, there is money just waiting for you in those big black plastic bags.

The key is sorting your garbage.  You should segregate according to degradability.  Non biodegradables are those that do not perish such as plastic, soda cans and such.  Biodegradables are those that disintegrate by itself over time.  Gather all plastics, soda cans and other items that can be recycled and put them in a separate plastic bag or in a box.

The next step is locating recycling centres that buy up trash from other people and recycle them into useful things.  There are recycling centres that have their contact numbers as well as address on the yellow pages.  You may also ask a friend who have done the same thing previously.

Selling your garbage is not only a financially rewarding endeavour.  It is also environmentally sound and it helps in keeping your house spick and span.  You should make a habit out of it and try to encourage people to do it as well.
