As someone who works in industry, we are always on the look out for ways of increasing recycling rates. Some ideas we have used (or looked at):
http://www.aerosolv.com - An aerosol puncturing kit. If you use a lot of aerosols at work, this gadget will puncture them, and the propellants/product will go into a drum, and the gases will pass through a filter. Dead simple idea, and turns a hazardous waste into something that can be sold for scrap! The US Navy use apparently, but don't let that put you off
Chimb Seperator. Chimbs are the metal rims on cardboard kegs. If your work handles loads of cardboard
pr fibre kegs, this device will remove the rims so you can send them for scrap, and the cardboard for recycling. (From Bryden Engineering in Leeds). Product is not on their website!
A company that sells environmental technology from around the world:
