We covered the issue (once or twice) of whether aluminium cookware leads to Alzheimers and had robust discussions (once, twice and thrice) on the risks associated with perfluorooctanoic acid (PFOA) in Teflon based non-stick cookware. In the latter case the US EPA is asking manufacturers to reduce their PFOA emissions by 95% before 2010. Into this debate comes GreenPan. It claims to be the "the first environmentally- friendly, PTFE-free non-stick cookware available since the introduction of non-stick technology in 1938." PTFE being Polytetrafluoroethylene, the chemical name for Dupont's Teflon trademarked material. The details for GreenPan are a little sketchy, but we are told it uses a Thermolon ceramic-based nano non-stick technology that has high heat resistance (850Â°F or 450Â°C) and is scratch and abrasion resistance. The marketing blurb suggests it will not will not break down or wear over time. Plus there are also claims that Thermolon-based cookware releases 50% fewer greenhouse-gasses during production. Curiously however it was launched nationwide exclusively online at HSN.com on Thursday, 26 July 2007. Now just a couple of days later there is no reference at all to the product line on their site. Very odd. But you can find more information at Thermolon and ::GreenPan. Via PR NewsWire.
