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.
With erupting concern over police brutality, law enforcement agencies are turning to body-worn cameras to collect evidence and protect police and suspects. But how do they work? And are they even really effective?
A half century ago, cars were still built by people, not robots. Even on some of the country’s longest assembly lines, human workers installed windows, doors, hoods, engines, windshields, and batteries, with no robotic aid.
DuPont's Hytrel elastomer long used in automotive applications has been used to improve the way marine mooring lines are connected to things like fish farms, oil & gas installations, buoys, and wave energy devices. The new bellow design of the Dynamic Tethers wave protection system acts like a shock absorber, reducing peak loads as much as 70%.
