Which batteries pile up on job sites, how to store them safely between pickups, how to run battery recycling across several projects, and which other regulated waste needs a plan.
A busy job site goes through batteries quickly. Cordless drill and saw packs wear out, laser levels and radios eat AA cells, and lifts, light towers and generators carry lead-acid batteries that eventually fail. Spent packs end up in truck beds, gang boxes and, too often, the roll-off bin. In California none of them can go in the trash, and a damaged lithium pack in a dumpster full of wood and cardboard is a fire risk.
Modern Waste Solutions has operated since 1999 from its Sacramento facility and recycles every common battery chemistry for contractors and other businesses throughout California. This guide covers the batteries that pile up on construction sites, how to store them between pickups, how to run battery recycling across several projects, and the other regulated waste a site should plan for.
| Source | Typical chemistry | What to watch for |
|---|---|---|
| Cordless tools and chargers | Lithium-ion; older packs NiCd or NiMH | Dropped or crushed packs can overheat; keep damaged ones apart |
| Radios, laser levels, meters, headlamps | Alkaline and lithium primary cells | Loose cells short against each other and against metal |
| Lifts, light towers, generators, compact equipment | Lead-acid | Heavy, acid inside, must stay upright |
| Temporary security, alarms and exit lighting | Small sealed lead-acid, NiCd | Collected at closeout and forgotten in trailers |
| Laptops, tablets and phones used on site | Lithium-ion (built in) | Recycle the whole device as e-waste |
Equipment batteries have their own storage and lifting issues. Our guide to lead-acid battery recycling covers them in detail.
CalRecycle bans every type of battery from the trash, from AA cells to lead-acid, and DTSC regulates most spent batteries as universal waste. The company that generates them is responsible for getting them to an authorized recycler, and a roll-off box is the first place an inspector or a hauler will notice them.
There is a practical reason too. Lithium-ion packs that have been crushed, punctured or shorted can go into thermal runaway, and a bin loaded with lumber, packaging and drywall scraps gives a battery fire plenty to burn. Batteries in waste trucks and sorting facilities are a known cause of fires. Our article on the risks of improper battery disposal explains how those fires start.
On multi-contractor projects, settle before work starts which company collects and documents spent batteries. When nobody owns it, batteries leave the site in whichever truck happens to be closest.
Where lead-acid batteries are charged on site, OSHA's construction standard (29 CFR 1926.441) applies. It calls for ventilation so charging gases can't build up, face shields, aprons and rubber gloves for workers handling acid or batteries, facilities for quick drenching of the eyes and body within 25 feet of battery handling areas, and a way to flush and neutralize spilled electrolyte.
Contractors with more than one active project do better with a standard setup than with a different habit at every site.
Our battery recycling service supplies containers for each chemistry, labeling, pickup and certificates. Yards and larger sites can join a route-based recycling pickup.
Batteries usually aren't the only item that can't go in the roll-off. Renovation and demolition bring out several streams with their own rules, and it helps to know which vendor handles which.
| Waste stream | Who handles it |
|---|---|
| Electronics: radios, tablets, cameras, access control, old building controls | We do, through electronics recycling |
| Solar panels removed from roofs | We do, through solar panel recycling |
| Asbestos, lead-based paint debris, solvents and fuels | A licensed abatement contractor or hazardous waste transporter |
No. Keep lithium-ion tool packs, alkaline cells and nickel-based batteries in separate containers. Mixing chemistries complicates recycling and raises the risk of shorts.
Stop using it, don't charge it, and move it to its own container away from flammable material. Tell us about it before pickup so it can be packed correctly.
Yes. We recycle lead-acid batteries from lifts, light towers, generators and other equipment. Keep them upright and give us a count and approximate size when you request pickup.
Yes, for contractors and other businesses, subject to route and access. Many contractors find it simpler to consolidate at their yard and schedule regular pickups there.
Battery recycling on construction sites comes down to a labeled container for each chemistry, somebody responsible for it, and pickups that keep pace with the project. Add electronics to the same plan and the roll-off stays clear of regulated waste. Request a quote for containers and job-site or yard pickups.

This was our first time working with MWS and they were amazing! Quick response time, efficient, and friendly. Ivan was the team member who was on site for the pickup, and he was great. He worked quickly, is very knowledgeable, and is so kind. It was so easy working with him. We are looking forward to using MWS for our E-waste and Universal waste needs in the future. - Sacramento City College Sustainability

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.
We had another vendor cancel on us last minute & Modern Waste jumped into action & was able to help us with ewaste & critical document shredding overnight. Team was helpful, professional & got the job done quickly & efficiently. We were able to complete an office move out/shut down in a day with their help! Highly recommend this business!
Thank You Gretchen! We are happy to make a difference.
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.
I needed hard drives on some old laptops destroyed so any old personal information can't be stolen. The guys there were friendly and helpful and fast. Thanks Pavel and Vincent. Thanks Modern Waste for doing a helpful fast service to us.
We truly appreciate your generous review! 😊 It's fantastic to know our team was able to assist you with your hard drive destruction needs efficiently. We are so glad to hear you had a pleasing experience with us. Our door is always open for all your future recycling needs!
