Dear Rachael,
 
Here is a suggestion for your recycling directory.  My wife is a local collecting agent for a charity called Workaid.  They collect old tools, get volunteers to refurbish them in the UK, and then send them off to people in Africa who can use them to make a living or improve their quality of life.  You can read more about Workaid and the things they collect here: http://www.workaid.org/.
 
Anyone who has any of the tools listed should contact my wife on 01372-378914.  She will confirm whether Workaid can take them.  Assuming yes, people just need to bring them to our house in Leatherhead.  We don't advertise our address though as we don't want things dumped at our front door.
 
I hope your project goes well, and congratulations on taking this initiative.
