EPA indicates landfill cover is not CRT recycling


The federal EPA has clarified its regulatory stance on whether leaded glass destined for tile manufacturing or landfill cover should be considered recycling.

In separate letters dated Sept. 10 and uploaded onto the agency’s website, Barnes Johnson, the director of the Office of Resource Conservation and Recovery, addresses the use of CRT glass as alternative daily cover (ADC) and as a flux and lead oxide in making ceramic tiles.

According to those letters, the ADC option is considered legitimate disposal while the tile option is legitimate recycling.

“Hazardous waste, such as CRT glass, that has been treated … and that no longer exhibits hazardous characteristics may be disposed in a landfill,” Johnson writes in the ADC letter. On the tile front, the agency states, “Based on the provided information, the EPA finds the legitimate recycling factors set forth in EPA policy … appear to have been met.”

The letters are addressed to two of the biggest names in the end-of-life electronics game: The ADC letter was sent to Sony, and the tile letter was sent to Sims Recycling Solutions, the electronics recycling wing of publicly traded Sims Metal Management. Sony had asked the agency for clarification on the ADC front, while SRS had requested clarification on the tile option.

It’s significant that the tile process received an OK to be deemed recycling while landfill cover is only considered “disposal.”

Both ADC and and tile applications are seen as emerging downstream applications for CRT glass, which has become increasingly burdensome for e-scrap firms. Consumers worldwide have moved to non-CRT technologies so glass-to-glass markets for recycling firms have eroded, but the backlog of old monitors and TV sets continues to head into the e-scrap recycling stream.

While the EPA’s two letters noted the authority of states to set forth “more stringent” regulatory policies than those asserted by the federal agency, states are likely to refer to the EPA letters for guidance on policy making in the CRT arena.

Kuusakoski U.S. is the only company currently offering the CRT-to-ADC option in North America, partnering with a landfill located in Peoria, Illinois. The process, according to the company, seals the lead within the glass to prevent leaching and then is spread on top of a landfill as ADC.  A Vermont-based firm also looked into the option.

Some states have already concluded the option is not recycling and therefore does not count toward manufacturer recycling goals. In addition, the R2 e-scrap environmental standard has banned the use of CRT glass as ADC. The other certification standard, e-Stewards, meanwhile, allows it as a “last resort,” but does not deem it recycling.
