HAZARDOUS WASTE DISPOSAL IN HILLSBORO, OR

Hazardous Waste Disposal for Hillsboro Semiconductor and High-Tech Suppliers

Washington County holds Oregon's largest concentration of semiconductor and electronics manufacturing, and the supply chain around it runs deep: equipment builders, parts cleaners, chemical distributors, contract manufacturers and test labs. Those shops generate small volumes of very specific chemistry, and the profiles have to match exactly what is in each container. Hillsboro generators also tend to sit near a generator-category line: a single month of heavy rework or a line changeover can push a small quantity generator into large quantity status, and in Oregon that month sets the status for the whole year. We help you plan pickups and one-time cleanouts so that doesn't happen by accident.

Acids, Etchants and Bases

Spent sulfuric, nitric, phosphoric and hydrofluoric acid mixtures, buffered oxide etch, and caustic cleaning solutions. Each is segregated by compatibility, packed in the right container material, and shipped with its own DOT description. Hydrofluoric acid waste is handled as its own stream, never mixed in with other acids.

Solvents, Strippers and Photoresist Waste

Isopropyl alcohol, acetone, NMP, PGMEA, photoresist developers and resist strippers, plus the contaminated wipes and gloves that go with them. Solvents with enough BTU value are profiled for fuel blending, and the rest go to incineration.

Slurries and Process Residues

CMP slurries, filter cake and settled solids from process tanks are sampled and characterized, then routed to stabilization, treatment or landfill based on the analysis rather than an assumption.

Lab Packs and Expired Specialty Chemicals

Expired reagents, unused specialty chemistries and unlabeled bottles from labs and QA rooms. We run field hazcat on unknowns, segregate by compatibility, and pack everything into DOT-compliant lab packs with a full inventory.

Parts Cleaning and Equipment Refurbishment

Equipment refurbishers and parts-cleaning shops produce acid and solvent rinses, contaminated wash water and spent media. We set up a pickup schedule that fits the production floor, so containers never sit past their accumulation window.

Tanks, Sumps and Water Utilities

Water utilities and industrial sites across Washington County use our 120-barrel vacuum trucks for tank and sump cleanouts. We pump, wash and haul industrial wastewater and solids to a permitted treatment facility, usually in a single day.

Aerosols, Batteries and Universal Waste

Aerosols, lithium and lead-acid batteries, fluorescent lamps and electronic equipment are handled under universal waste rules, so they don't count toward your hazardous waste totals or push you into a higher generator category.

Supplier Audits and Documentation

Prime manufacturers audit their suppliers' waste handling. Every shipment goes out on a Uniform Hazardous Waste Manifest with land disposal restriction notifications, and the signed copies, profiles and disposal records come back organized for your file.
