A new UN study out this week describes the global rush for lithium, cobalt, and nickel as the 'oil of the 21st century' — fueling poverty, water contamination, and health crises in the countries doing the extraction. That's a global story. But it has a local angle worth sitting with.
The electronics, batteries, and construction materials that end up in San Diego dumpsters contain the same minerals the UN is flagging. When those materials get illegally dumped in a canyon in Santee or a vacant lot in Lemon Grove, they don't disappear. They break down. They leach. They end up somewhere.
Separately, a UN special rapporteur has described a pattern of the U.S. using Mexico as a 'garbage sink' — lax oversight, inadequate standards, accumulated pollution. San Diego sits on that border. What contractors and haulers do here has a short trip to becoming someone else's problem downstream.
This isn't a call to panic. It's a call to be deliberate. Hazardous materials from remodels — old flooring with adhesives, roofing with asphalt coatings, drywall, treated lumber — need to go to licensed facilities that track what they receive and process it properly. The same goes for batteries, paint, and electronics from any teardown or cleanout job in East County or anywhere else in the region.
The practical standard is simple: know where your load goes. Ask the hauler. Keep receipts for loads that include regulated materials. Use permitted transfer stations and disposal facilities. If you're a property manager in La Mesa clearing a unit, or a small contractor finishing a kitchen demo in Chula Vista, this applies to you. The systems exist. The question is whether you use them.
What to do with your next load
- Separate batteries, electronics, and paint from general debris before any hauler picks up your load — these are regulated materials that need dedicated drop-off.
- Ask your hauler for the name and address of the facility receiving your debris. A legitimate operation will answer that without hesitation.
- For remodel projects in El Cajon, Santee, or unincorporated East County, check whether your material includes asbestos-era products before scheduling a pickup — improper disposal carries real fines.
- Keep a receipt or manifest for any load that includes construction debris. If a compliance question comes up later, documentation protects you.
- Do not stockpile construction waste on site for more than a few days in San Diego's dry season — heat accelerates chemical off-gassing and creates fire risk.
