Elizabeth, what I really liked about this one was the multi-win-win strategy. Keep a potential pollutant out of landfills, use something that's otherwise thrown away (=trash) to squeeze even more value out if it (aka recycling of a sort), make a better product with it that's also got a better carbon footprint than the previous ingredient, and help farmers make more $$ by selling the  cellulosic trash instead of paying to have it hauled away. Now--how do we apply this model elsewhere?

Rob, the whole second-generation phase of biofuels is surprisingly unknown to many people, especially here in the US. That second generation is the use of non-food crops, on soil that can't be used for food crops, etc. etc.

Thanks for presenting a different side about how the refuse from these crops can be reused, Ann. I didn't realize there was this type of research being done, but it's good to see! Anytime natural waste materials can be reused to improve something else, that's a good thing.

Very interesting, Ann. Nice use of waste materials, especially since everything usable has already been squeezed from these materials. I also like that it's non-food materials that are going into the concrete.

Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
Plastics designed for use in medical devices and hospital equipment have to do multiple jobs, as is made clear in an article in our sister publication MDDI.
Arevo Labs has developed a new filament 3D printing process for making very high-strength PEEK- and PAEK-based carbon fiber composites, and the commercial service is now available.
Some of the biggest challenges for adhesives that join multiple materials are coming from consumer electronics, especially mobile and wearable devices.
Whether it's the outside of an aircraft, the inside of an electronics module, or the surface of heavy-use industrial flooring, these coating and sealant materials are suitable for the job.
