### OPTIONAL POLLUTION PREVENTION INFORMATION

To claim information in this section as confidential circle or bracket the specific information that you claim as confidential.



## In this section you may provide information not reported elsewhere in this form regarding your
efforts to reduce or minimi ze potential risks associated with activities surrounding manufacturing, processing, use and disposal of the PMN subs tance. Please include new information pertinent to pollution prevention, in cluding source reduction, recycling activities and safer processes or products available due to the new chemical substance. Source reduction
includes the reduction in the amount or toxic ity of chemical wastes by technological modification, process and procedure modifica tion, product reformul ation, raw materials substitution, and/or inventory control. Recycling refers to the reclamation of useful chemical components from wast es that would otherwise be treated or released as air emissions or water discharges, or land disposal. Description of pollution prev ention, source reduction and recycling should emphasize potential risk reduc tion subsequent to compliance with existing regulatory requirements and can be either quantita tive or qualitative. The EPA is interested in
this information to assess overa ll net reduction in toxicity or environmental releases and exposures, not the shifting of risks to other e nvironmental media or no n-environmental areas (e.g., occupational or consumer exposure). In addition, information on the relative cost or performance characteristics of the PMN substance to potential alternatives may be provided. All information provided in this section will be taken into consideration during the review
of this substance. See the rev ised Instructions Manual that in cludes a Pollution Prevention manual for guidance and examples.

Describe the expected net benefits, such as (1) an overall reduc tion in risk to human health or the environment; (2) a reductio n in the volume manufactured; (3) a reduction in the generation of waste materials through recycling, source reduction or other means; (4) a reduction in potential toxicity or human exposure and/or environmental release; (5) an increase in product performance, a decrease in the cost of production and/or impr oved operation efficiency of the new chemical substance in comparison to existing chem ical substances used in similar applications; or (6) the extent to which the new chemical substance may be a substitute for an existing substance that poses a greater overall risk to human health or the environment.

This substance is manufactured in support of [ for use in the

Electronics market segment. [ ] are [ employing efficient [

emitters; the energy consumption for mass-produced [ ] is expected to be 30% lower

than that for equivalent [ . Intrinsic to the design of an [ is that more of the

light generated by the light source is actually utilized [ and the efficiency with which that

light is generated improves the overall power consumption.

Eliminating the [ steps involved in [ processing replaces the subt ractive process of patterning

~10g of [ per [ glass to the additive process of c oating and printing <1g of [ ]

materials per [ ] glass, reducing waste. Current [ ] made by [ employ structurally similar

materials but deposit them by [ ] . This process wastes 80-90% of the consumed

materials. The [ process employed with the [ ] materials wa stes only 10-20% of the consumed material.
