Re: depends on the cost and the benefit

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.

Latest Analysis
2016 engineering grads can expect to earn an average salary of $65,000 right out of the gate. Petroleum engineers' wallets are much fatter, though -- they are expected to earn about $20K more.
3D printing is now adding value to manufacturers at all steps along the business value chain. Come find out how at a talk by John Jaddou at next month's Embedded Systems Conference in Minneapolis.
From IoT and M2M to flexible robotics and consumer HMI, the advances in smart manufacturing are being deployed on the packaging floor.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Ear-based heart-rate monitoring gained momentum recently, as sensor maker Valencell Inc. announced it has licensed its biometric earpiece technology to Samsung Electronics Co. Ltd for use in so-called “hearable devices.”
