Good article explaining the detection method for CNT's in soil. Are there toxicity concerns for CNT's in product? Also, are there concerns with the processing method used to add the CNT's to the base material?

life cycle concerns

Ann, this is indeed a concern.  Like many of the clever solutions to engineering problems, we have to think of the effect on living organisms, not just humans.  Semiconductor manufacturing also uses many toxic chemicals, for example, and these have to be controlled.  This is true at the point of manufacture and at the point of disposal.  I recall that even the ink used in thermal printers, such as those that are used to print receipts at stores, can be toxic.  We need to be careful in handling exotic, engineered materials.

One question I do have is about the detection method.  Since microwaves are used, I assume that the tests done on earhtworms are destructive.  Soil, even after being exposed to microwaves, is still just soil.  An earthworm on the other hand...

In this slideshow's latest crop of new bio-based and renewable plastics and methods for making them, some materials can even be completely recycled several times without loss of original properties.
It's probably too late to buy one, but some lucky people will soon be the owners of only 50 electric motorcycles made entirely with 3D printing from a super-lightweight aluminum alloy.
Oak Ridge National Laboratory has developed a surface preparation method to improve joining carbon composites with aluminum, with potentially far-reaching ramifications for high-volume industrial applications.
Our latest crop includes ABS alternatives, tougher PLAs, flexible plastics including a flexible nylon, polymers with better heat resistance, and the first biocompatible resin for desktop 3D printing.
New and improved fastening methods are helping engineers join plastics, composites, and thinner metal sheets in a variety of product assemblies.
