The word is in: An article in yesterday’s New York Times declares that stainless steel is better than plastic bottles for the environment–if one stainless bottle takes the place of at least 50 plastic bottles. The two writers of the column are developing a software product that conducts lifecycle assessments. They issued their verdict on stainless steel bottles after taking into account the environmental impacts of mining iron ore, chromium, and nickel, transporting them large distances, making the steel, transporting the steel, fabricating the bottles, and so on.
I can’t comment on the quality of the argument because zero data is provided on any of the inputs, and no information at all is provided on the plastic product.Assuming they are correct, however, isn’t this a little strange? Under what circumstances would someone use a stainless steel bottle to drink water? A hike maybe. No, stainless is too heavy. And how does stainless steel get into the recycling stream? Do you take it to a car shredder? What if people re-fill plastic bottles to drink water?
And what about the environmental waste of printing this silliness on half a page of the New York Times and distributing it across North America to a million people?
Dow Chemical and several other companies have launched a program in Omaha, Neb. to divert about 36 tons of plastics from landfills in its first phase, and convert it into energy used for cement production.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
