DuPont Recruits 500 Farmers for Non-Food Biofuel Project
Next year DuPont plans to complete one of the first and biggest commercial-scale cellulosic biorefineries in the world, which will make biofuel from corn stalks and leaves at this Nevada, Iowa construction site. (Source: DuPont)
I am sure your cost argument is valid but I wonder how much of that argument comes from a culture that is entrenched in how things have always been done and doesn't want to branch out and make the effort to do something new with the waste. I suppose it will take efforts like DuPont's (which I applaud, by the way) to see how this can be both environmentally and financially sound for all parties involved. Maybe you're right and it's policy that will change things and support this so it benefits the farmers as well.
Ann, don't get me wrong, but I still have to wonder about the economics of this. After one of your previous articles I was down on a farm here in Illinois. I asked the fatmer about it. He had significant corn stubble left in his fields. He was aware of the opportunity, but pointed out that he would have to bundle the stalks for them to be used. The indication was that it was not worth the cost. Costs include fuel, equipment wear and farmer time (and wear).
Getting the most from a raw material is very attractive from a social and environmental point of view. The problem comes in the economics. There was a recent article I saw about ethanol producers trying to get more out of the corn by developing secondary products. One was a protien that could be used to make plastics. So, even using the "leftovers" from a process, it turns out that it is cheaper to petroleum based products for the same purpose. These are the kind of engineering trade studies I have seen in a myriad of businesses.
It may take tax and environmental policies to tip the scales.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
