It often sounds like some people don't dispose of recyclables properly because they simply don't know where to go for certain things. A little lazy, sure, but one place making that info easily accessible is Earth 911: Environmental Recycling, Reuse & Renewal.
This site has so much varied information for living green and living well, and on the top of every page: an easy search engine to find a local recycling center nearest you (for all types of products).
Site also includes event lists, discussion forum, and world news on green issues.
PS. The site is currently looking for environmental writers to join the team. Click here for all information.
