Adjustment in HDPE bottles may save oil
As a recycler, we want to clarify some inaccuracies in the story ``Low supply stymies recyclers,'' in the May 21 issue of Plastics News [Page 1]. First, colored opaque PET bottles account for the greatest amount of yield loss among high density polyethylene recyclers, not HDPE containers that contain calcium carbonate.
In addition, the number of HDPE bottles with calcium carbonate that sink in the recycling stream are smaller than the number that sink in lab tests and there is no set percentage of calcium carbonate that will cause an HDPE container to sink. That is the opposite of what the article states. The amount of calcium carbonate that will cause an HDPE container to sink depends on the pigments and additives in each bottle.
Utilizing calcium carbonate in HDPE bottles can reduce our nation's dependence on petroleum. If all bottle makers used 3 percent of calcium carbonate in their product, it would displace more than 100 million pounds of a petroleum-based product
Stimulating innovative out-of-the-box thinking and working together with others can resolve many of the complex issues we face and result in real positives for the environment.

Letters offer varying points of accuracy
The two letters in the April 16 issue [Page 6] are a small study in contrasts. Roger F. Jones presents a very clear and well-grounded commentary on another one of those ``U.S. is losing ground'' stories you like to print [``America not losing ground on commerce'']. For my money, he gets the subject exactly right, including his closing thought that, ``I don't think we really want the government to be picking economic winners and losers.''
On the other hand, Snehal Desai wrote one of those buzzword letters that sounds good but doesn't say much [``Key to success: Work with the stakeholders'']. I guess my problem with it is the multiple references to ``stakeholders,'' with a ``sustainable'' thrown in. I don't know what stakeholders are, beyond suppliers and customers. I presume they are interested parties to commercial transactions who don't buy or sell. But how does one become a stakeholder? Show interest? Are they self-selected then? How credible is their claim to be a stakeholder? And if they ``have not been part of the commercial process,'' why should they be involved or considered, beyond what's legal and moral?
Of course, I know the answers really, and the biggest stakeholder of them all is the government Mr. Jones warns us about. No we don't want that stakeholder, nor do we want anti-everything Luddites deciding who the winners and losers are. Let the commercial world function and keep the people who think they know what's best, but don't have an economic stake in the process, stay on the outside.
