Netgear have a recycling program where you can send in any brand of old product free of charge to be recycled when you purchase a new Netgear product. Details at http://www.netgear.net.au/recycle/
Procedure wise just pack up the old unit, fill out the form which generates a reply-paid label then drop it in the post.
On receipt, Thiess Services (the recycling company) will separate out the heavy and ferrous metals and plastics to be melted down and made into new stuff. Brilliant!
Thumbs up to Netgear!
