This Week’s News about Recycling and End-of-Life Composites
#composites, #sustainability, #recycling, #end_of_life_composites, #thermolysis This week I’m going to make my newsletter just a bit shorter than what I did last week with all of the pictures of sailboats that use recycled or natural fibers for primary structure. There are a couple of fairly newsworthy things that have happened just in the last few weeks that I want to focus on this week. And I want to also let everyone know that I am going to take a couple of weeks off wri

Natural Fibers and Racing Sailboats – How Much Fun is That?
#racingsailboats, #sustainability, #naturalfiber, #flaxfiber, #bamboofiber, #bioresins I saw an article in Composites World this week about a flax fiber boat manufacturer I wrote about two and a half years ago – Greenboats – that has been building recreational sailboat hulls since about 2020 using flax fiber. They source their flax of course from France which grows more of this stuff than any other country in Europe. Anyway, the article is about a strategic partnership betw

A Few More Tidbits in Composites Sustainability News
#composites, #sustainability, #energyefficiency, #renewableenergy, #fibers, #resins I received my November Issue of the Composites World magazine (electronically of course) this week and as usual it had a couple of interesting developments in the world of composite materials sustainability, one of which is sort of fun – if you like water sports. So, I thought I would write about these and a couple of other things that I came across in my information feed about composites. A
