The City of Austin recently launched a new program called the Green30 Challenge through which eligible participants can get a rebate of 75 percent of the total cost of the composting system (taxes excluded) up to $75 in value by following the three following steps:

1. Downsize to a 30-gallon green garbage cart
2. Take a free basic backyard composting class
3. Purchase a home composting system

If you already use a 30 gallon cart, you just need to take the class to get the rebate. Check out this website for more details.
