Contra Costa County covers refinery towns, a working port, BART-served office districts and some of the East Bay's quieter professional suburbs. On one day we might clear shop electronics from a refinery contractor in Richmond or Martinez; on the next, decommission a server room on a San Ramon corporate campus or collect a few drives from a Lafayette law office. We run all of it under the same certified process.
Every city below has its own page:
- West County: Richmond (port and Chevron refinery), El Cerrito (compact, BART-served, apartments and shops) and Hercules (waterfront redevelopment).
- Central County: Martinez (county seat and refinery contractors), Concord (office parks and the Naval Weapons Station redevelopment), Pleasant Hill and Walnut Creek (BART-adjacent office towers and Broadway Plaza retail).
- Lamorinda and the San Ramon Valley: Orinda, Lafayette, Danville (professional offices that want discreet data destruction) and San Ramon (Chevron's headquarters and other large corporate campuses).
- East County: Pittsburg (industrial waterfront), Antioch (small businesses and property managers), Oakley (new shops and rental homes) and Brentwood (farms and new retail centers).
We also serve San Pablo, Pinole, Rodeo, El Sobrante, Moraga, Alamo, Bay Point, Discovery Bay and the Contra Costa Centre area. If you don't see your town, request a quote and we'll confirm.
Any retired business electronics qualify: desktops, laptops, servers and networking racks, UPS systems, copiers and printers, phone systems, TVs and monitors, POS terminals, audio and video equipment, all battery chemistries and hard drives. The work behind a pickup can include:
- Electronics recycling with reuse reviewed first.
- IT asset disposition for fleets of laptops and desktops with resale potential.
- Data center and UPS decommissioning for campus server rooms.
- On-site hard drive shredding when drives can't leave the building intact.
Six steps, the same in every city: containers, training, a pickup by our own crew, tracking under a ticket number, processing at our Sacramento facility, and certificates and reports. Every Contra Costa pickup runs under our ISO 9001, 14001 and 45001 certifications, and larger jobs can be phased across buildings with separate paperwork for each phase.
Discarded electronics and batteries are universal waste in California, so they can't go in household trash or a business dumpster. Our pickups are for businesses and agencies, and we don't offer residential service. Household electronics go to Secure Recycle, our sister company for consumers, which operates from our Sacramento address at 3921 Pell Circle. Contra Costa residents can also use a nearer site from CalRecycle's list.
Do you offer recurring pickups?
Yes. We run recurring route-based pickups and on-call pickups. Retail and office clients with steady turnover usually prefer a schedule; a one-time lease-end clear-out is booked on call.
Can one program cover sites in several Contra Costa cities?
Yes. A company with offices in Walnut Creek and a warehouse in Richmond can run both under one account, with tickets, certificates and reports kept separately for each site in our client portal.
Request a quote with your city and a rough idea of volume, whether that's a single office in Lafayette or a data center exit in San Ramon.
No obligation. We respond same business day.
Reviews
A little bit off the beaten track in Natomas, but Modern Waste quickly and efficiently helped me recycle my broken Lithium Iron Phosphate batteries at a reasonable $/lb fee (Sac county e-waste will not accept these items). Ramiro and Vincent were very friendly and helpful.
Chris was awesome! He came in and picked up all of the e-waste we had ready for him. He was polite and professional throughout the entire process. He handled the equipment with care, including the site equipment that was already in place. I am very happy with his service and appreciate the great job he did.
Aaron and Vincent were awesome, excellent customer service!
Great guys, excellent customer service, highly recommend!
