When most people think of supporting charities, they think of money. This can be a problem for people who are struggling to support their own families. Even if your assets are limited, you can still help. Here are just a few ways to raise money for charities that won't cost you anything.

Recycle cell phones

Fast changing technology means people replace their cell phones more often than other possessions. However the phones have toxins that damage the environment if disposed in landfills. What's the alternative? Recycle! Cell phones can be donated to almost any charity.

Organizations such as American Cell Phone Drive partner with thousands of charities to recycle cell phones. The recycler then pays the charity cash for the phone. Any charity can raise money by joining a program to recycle cell phones.

There are more than just environmental benefits when you recycle cell phones. Many phones can be repaired and reused, and reuse is the best way to recycle. Cell phones can be donated to people in developing countries where it is not economical to install regular telephone service. Another reason to recycle cell phones is to provide emergency communications. Did you know almost any cell phone can connect to 911, even if the phone is not currently active with a carrier? Families who can't afford even basic telephone service can still have access to life-saving emergency assistance.

You can do even more to recycle cell phones by canvassing your friends and family. You might be surprised how many of them have an old cell phone in a drawer somewhere ready to raise cash for your favorite charity.

Join a "thon"

Charities have found that walk-a-thons, read-a-thons, and similar activities are very efficient methods of fundraising. They are inexpensive to setup and operate, generate good revenue, and are fun for the participants. Often people see beneficial side effects. For example, read-a-thons promote literacy and walk-a-thons encourage exercise and good health.

To participate in one of these activities, you collect pledges from family, friends, and neighbors. Then when the time comes, you read or walk your heart out. The more you do, the more the charity raises.

If that seems to tame for you, come up with your own idea. You might be surprised how much your friends will pay to pelt you with tomatoes or watch you shave your head.

Save money to make money

Find small ways to save yourself money and pass those savings on to charity. Use coupons at the grocery store. Buy a few store brand products instead of name brands. If you eat lunch out every day, start bringing lunch once a week instead. Rent a movie instead of going to the theatre. Each time you save money, put the savings into a charity jar and donate the proceeds once a month.

You can also choose brands that donate to charities. The Paul Newman brand donates huge portions of its profits to charity organizations. Ben and Jerry's does as well and also support local farmers and purchase products from developing countries to support economic growth.

There are many more ways to donate to charity without spending your own money. Most non-profit organizations are desperate for volunteers and even a couple hours of your time a week can make a tremendous difference in someone's life.
