As the use of tracking tags grows, some people are concerned by the potential environmental impact of the radio-frequency identification devices. Generally the concerns involve recycling the tags.

Joe Dugan, president and CEO of the RFID company RF Code, said there needs to be a U.S. recycling program for the tags, and "we want industry to be responsible." Last week, RF Code announced that all of its RFID products are now lead-free and comply with a European Union directive banning the use of certain toxic chemicals within the region.

Dugan said Congress should provide RFID usage guidelines for the United States.

There are two types of RFID tags, passive and active. Passive tags are powered externally, while active tags must carry a source of energy that enables them to operate internally. Dugan said passive tags are meant to be disposed of quickly.

Clarke McAllister started his company, ADASA, to find a solution to the possibility of RFID tags piling up as the industry grows. His company has pursued innovative methods of removal, recovery and re-use of RFID tags.

Angie Leith from the Environmental Protection Agency said in a 2005 presentation that the EPA wants to make sure RFID technology does not present any problems that could affect the current recycling and re-use infrastructure. The EPA supports working in partnership with industry and other government agencies so the tags are environmentally benign.

An intra-government U.S. RFID Council meets a couple times a year to discuss such issues, Leith said during a telephone interview.

Many industries -- including steel, aluminum, plastic, paper and glass -- are concerned that when RFID tags are attached or potentially embedded within products and not properly removed, the effects on the recycling process could be serious.

The American Iron and Steel Institute warned in an April release that RFID tags made with copper as the antenna component would be devastating for steel recycling and the steel industry in general because of the possibility of the RFID tags mixing with steel scraps. On the other hand, it said the use of aluminum would have "no discernable effect" on the recycling process.

The steel industry is calling on the government and business entities to reject the development of copper-based tags.

An expert group on RFID formed by the global trade association AIM submitted a draft standard to the International Organization for Standardization last month. It highlights the concern that although RFID is poised to help with the recycling of various products, many recycling streams are challenged by tags.

"Mandated RFID tagging by major retail and government entities creates a situation where massive amounts of RFID tags will be entering the waste stream of the container or item to which the tag is attached," according to the standard.

• See the following Web site: http://itvibe.com/news/2767/ Why is no one reporting on the obvious security flaws in RFID? The government is progressing toward chipping all animals (and then possibly people) with RFID tags. No one has done any research on the downside: The environmental concerns are the tip of the iceberg. For example, if chickens get a chip, what happens to the tiny chip during food processing and consumption? If chips are vulnerable to hackers, should they be use to ensure food security? Reference: http://www.rfid-weblog.com/50226711/nonaisorg_we_dont_need_no_stinking_tags.php I believe the RFID program is about to hit a nerve in the public awareness, especially after a few passports are hacked.

• The benefits of RFID have been widely discussed as it pertains to the manufacturing, logistics, and distribution process. This chain only represents one part of the input-throughput-output process. RFID could be the enabler of a broader recycling initiative in which tags inform the garbage disposal system (garbage trucks) on what elements, plastic types, paper types, etc., are contained within the waste products before delivery to an RFID-integrated automated recycling facility that can process a broader array of waste products. At the very least, this gives policymakers a better handle on itemized waste metrics. Sean Evans Posted August 8, 2006 1:41 PM
