It's Just String & Glue. This is a newsletter about composites, the strings, the glues, and the business.


There’s a New Entrant in the Sustainable Natural Fiber Composites Business
#composites, #sustainability, #flaxfiber, #naturalfiber, #recyclable, #greencomposites I’ve seen a couple of posts in Composites World about a company in Turkey that has developed a series of textile products using a mix of flax and hemp fibers specifically for use in composites. And this company, Bpreg, doesn’t just deliver the fiber product, they also pair it with a recyclable thermoplastic resin and sell their products in prepreg form – hence the name Bpreg. I wanted to h

Circularity Challenges and Opportunities for the Composites Recycling and Reuse Business
#composites, #sustainability, #recycling, #reuse, #recycledfiber, #recycledresin This post is the fourth in the series that introduces the ideas spelled out in my second book, just released – “Sustainable Composite Materials: A Roadmap to a Circular Economy”. In the first three posts I talked about sustainability and circularity in the raw materials supply chain, reducing the carbon footprint in the making of both fiber and resin, and reducing the carbon footprint in the pro

How to Make Composites Processing and Fabrication Sustainable
#composites, #sustainability, #energyefficiency, #renewableenergy, #fabrication, #processequipment This week’s newsletter is the third in my series laying out the roadmap to sustainability in composites. But before I get started, I need to let everyone know that my second book, “Sustainable Composite Materials, A Roadmap to a Circular Economy” is officially released as of April 6 (Monday). The book covers the watershed of the issue of sustainability for these wonderful mate

Sustainability in the Composites Raw Material Supply Chain
#composites, #sustainability, #rawmaterials, #greenmaterials, #naturalfibers, #naturalresins I’m going back to what I wrote about a couple of weeks ago – the recommendations for the composites industry that I have in my upcoming book. I promised that I would deal with each part of the industry in turn until I got all the way to the recyclers, talking about where we are today and what I see as a path to sustainability that each piece of the industry can take.

Flax, Flax, and More Flax, And Some Other Stuff
#composites, #sustainability, #flaxfiber, #biocomposites, #fibers There appears to be quite a bit of movement in the natural, plant-based fiber business this past week or two. Two announcements came out in Composites World about companies that are scaling up their flax fiber composite reinforcements business, and another one that I will talk about a bit later about a basalt fiber production facility being built in the Middle East.

Natural Carbon Fiber Precursors – How About Thin Air?
#composites, #sustainability, #energyefficiency, #renewableenergy, #fibers, #resins Yes, in fact, a company in Houston called Mars Materials, Inc. which is a public benefit corporation incorporated in Texas, teamed up with the Textile Innovation Engine of North Carolina and NC State University to take CO 2 captured from the atmosphere and ammonia/bio-based feedstocks and turn it into acrylonitrile. The Textile Innovation Center at NC State tested the Mars material and found

A Bit of Sustainability News and Some Other Stuff
#composites, #sustainability, #rotorsails, #environmentalproductdeclaration, #recycling There has been a bit going on since my last post in 2025, so I thought this week I would catch everyone up with the sustainability initiatives across not only the composites industry itself, but in industries and sectors of the economy that are making heavy use and initial use of composites.

The Maturation of Composite (Fiberglass) Structural Shapes in Construction
#composites, #fiberglass, #structural_shapes, #construction, #composites_in_construction In this last post of 2025, I wanted to complete what I started last week and talk about fiberglass being used for structure in the construction industry. Specifically I want to chat a bit about the evolution of what we have today as standard structural shapes as well as where these products are beginning to replace steel in construction.

Glass Fiber Composites in the Construction Industry
#composites, #sustainability, #rebar, #fiberglass, #frp_rebar, #concrete_reinforcement I thought for this week I would change course a little bit and talk about the construction industry and the application of composites to that industry. The thing that prompted this is an article in Composites World (12/1/2025) announcing that ACMA – The American Composites Manufacturers Association – has put out what they call a product category rule or PCR for fiberglass rebar. And for t

Composite Fiber from Rocks? Yes, as a Matter of Fact
#composites, #sustainability, #basaltfiber, #basalt, #fibers I have been seeing some interesting posts lately about the application of basalt fibers to all manner of composite material products and parts. I had not thought much about it until a recent post in Composites World (11/10/2025) talked about a new replacement for steel rebar made from basalt fibers. For those of you that aren’t rock people or that did not grow up in a part of the country where there were volcanoes

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

What is the State of the Art in Wind Turbine Blade Recycling
#composites, #recycling, #windenergy, #thermolysis, #solvolysis, #pyrolysis, #sustainability I have talked about this repeatedly by giving examples of companies and organizations, some largely funded and supported by governments, in previous posts. This week, I thought I would provide a summary of what I see as the State of the Art in recycling wind turbine blades here in the US and in the EU and UK. A lot has happened in the last couple of years, and some companies are not

Update on REFRESH Project – New LCA Study on Wind Turbine Blades
#composites, #sustainability, #windenergy, #recycling, #renewableenergy A few weeks back I wrote a couple of articles, one about this project (REFRESH) and another about a company in Norway (Gjenkraft) that has gotten seed money to build a plant to recycle wind turbine blades using their pyrolysis process. And of course the day after I wrote the article the REFRESH project posted the results of a Life Cycle Assessment (LCA) that they had performed by a consulting company in
