Here's an interesting thing on the sustainability front: recyclable windshield wiper blades. (No idea if they're any good, though I'm going to buy a pair and I'll comment later. This is link to the manufacturer, not a retailer.)
Jamak Fabrication, one of the largest manufacturers of wiper blades, has created the Tripledge® GREEN Wiper Blade ‐ the first ever 100% fully recyclable wiper blade. The Tripledge® GREEN Wiper Blade is a high‐quality, durable, silicone blade produced so that all components can be recycled. Silicone is not a petroleum‐based product; therefore it is easily recyclable, unlike organic rubber squeegees. Jamak has created a unique technology which can repolymerize the silicone blade 100% back into a raw polymer product and make new silicone products immediately. No landfill. No partial recycling.
JAMAK wants to encourage customers to recycle their Tripledge® GREEN Blades once they need to be replaced (The National Highway Transportation Board recommends that drivers change their wiper blades every year). When customers send in their old Tripledge blades to Jamak, the company will recycle them 100%!
