Solid Waste Stream Assessments determine the components of given waste streams. An evaluation of findings allows components to be targeted for effective source reduction, reuse, or recycling. LLNL assessed 10% of its onsite dumpster locations (25 of 250). Dumpsters were selected based on location and surrounding facility use. Dumpster contents were sorted according to type into containers. The filled containers were weighed and photographed. The information was noted on field tabulation sheets. Dumpster locations, date of sort, sort categories, weight, and cubic yardage were entered into a database for review and tabulation. LLNL sorted approximately 7000 pounds of waste in each of the two assessments. A high incidence of cardboard (uncompacted) was present in most dumpsters. A high incidence of polystyrene was also present at dumpsters serving the LLNL cafeterias. Very little glass or aluminium was found. Enough waste paper was present to indicate that the paper recycling program needed increased employee awareness and a possible expansion. As a result of our assessments, LLNL has expanded its cardboard and paper recycling programs and implemented moving box and pallet reuse programs. LLNL is also studying a possible recycling program for cafeteria polystyrene and possible program expansions for magazine, newsprint, and glass recycling.
