Another greener telemark boot, also from Scarpa. (Check here for a review of the Scarpa T2 Eco boot).
From the company: “The freeride boot for those who work/play/live in their boots is now made from Pebax Rnew”, a renewable plastic derived from castor oil. This renewable material extracted from the oil rich seed (40% to 60% oil) of the castor oil plant, or Ricinus communis, has many positive industrial design qualities. According to Warren McLaren, who writes for the Treehugger website, “castor oil has been adopted by chemical company Arkema to manufacture a thermoplastic elastomer (TPE) they brand as Pebax. Their Rnew version is considered to be the bio-based TPE to offer high performance without compromises. Some of those performance characteristics include: low density, flexible without fatiguing, energy return, power transmission, low temperature application, chemical and ultra violet (UV) light resistance.
Extra info on the technical properties of Pebax is available here.
No information on working conditions as yet.
I cannot find any distributer details for Australia as yet, perhaps ask around at your local store to see if they can get them in.
