Student Abstracts: Waste Management at PNNL

Mop Water, Trim Sol, and Recycling. MELISSA ROBERTSON (WSU, Pullman, WA 99163) KATHY POSTON (Pacific Northwest National Laboratory, Richland, WA 99352) .
Throughout the summer I have been working on a major trash-recycling project and managing a Mop water/Trim Sol waste stream. I have been following up on these three projects for about eight weeks. I conducted all of the research by interviewing,sampling,Internet researching,and document requests. The two waste streams had many options for treatment and I had to narrow it down to one consistent and effective method. Some of the options looked at were evaporation, extending life/paired with evaporation, disposal/incineration,and recycling/filtering. The dumpsters were surveyed by volunteers on a weekly basis according to a pickup schedule. A database was created in order to track the building,time,date,level,and material in the dumpsters. From this information I was able to go back and see what actions need to take place. A meeting was held concerning the Trim Sol and Mop water waste streams where we discussed the options at hand. The best option chosen was extending life/paired with evaporation. A "new technology" cutting fluid product will be used, demineralized water, an antimicrobial agent will be added to the sumps, and the waste will be evaporated. A meeting was held where the data was reviewed and a proposal was produced. We are going to separate the buildings into two categories;opportunity for reduction and no reduction needed. The buildings that have an opportunity for reduction will be continually surveyed to collect more data to produce a plan of action. Both projects served the purpose of reducing the amount of waste being returned to the environment. The goal was to reduce the quantity of waste being generated and to possibly eliminate the source of waste.
