Biological Treatment of Solvent-Based Paint

摘要

Paints utilized for military purposes are formulated to stringent military specifications (MILSPECs). After the shelf life has expired, the paint can no longer be used for its original purpose/application. Furthermore, Navy policy prohibits the use of reformulated MILSPEC paint on anything classified as mission critical; therefore, treatment/offsite disposal are the only two alternatives available for managing this waste. As a result, management and disposal of expired shelf-life (ESL) paint is the Navy's most expensive waste. ESTCP funded a demonstration to evaluate biological treatment of ESL paint as it appeared to be the most promising technology. NAVFAC ESC's system experience and data collation raised major issues related to aerobically digesting ESL paint under the current design. First and foremost is cost effectiveness. The highest cost, by far, is labor and electricity, due to the limited throughput of the system.
