Waste Management
for Air Pollution
Reduce CO2, odor, and regulated smog-forming pollutants like NOx, SOx, VOCs, and PM2.5 at the source. Our modular system plugs into existing exhaust streams. When it's full, we swap it out like standard trash pickup.
Climate Protection
Captured right at the source. Our system converts CO2 into stable mineral solids. No compressed gases or hazardous materials.
Cleaner Operations
Target smog-forming pollutants and particulates for cleaner operations and easier permitting. Improve air quality in your neighborhood.
Human Health
Reduce odors and pollution that is hazardous to human health. A scalable system to address harms from wildfires & secondhand smoke.
Meet your pollution reduction goals today...
and tomorrow.
Our modular hardware adapts to meet your specific emission reduction targets. We can scale to meet your current and future emission reduction needs.
Smog
A high-impact solution for diesel generators. Lower maintenance burdens, increased fuel efficiency, & better cold weather performance.
How It Works
Filter
The Carbon Dumpster connects directly to your existing fossil fuel equipment's exhaust. It filters your exhaust and converts pollutants into minerals that are easy to manage.
Swap
When the Carbon Dumpster is full, a truck comes with a fresh Dumpster and hauls away the full one.
Dispose
Sandbox Carbon safely disposes of the various minerals, ensuring your air pollution never reaches the atmosphere.
Why it works for you
- Modular & Scalable
- No hazmat or compressed gases
- Minimal energy load
- Plug-and-play with existing equipment
- Predictable monthly lease and service fees
- Zero on-site maintenance: we handle filter swaps and material disposal
Commercial Buildings
A plug & play solution to slash emissions from boilers, furnaces, and other natural gas powered appliances.
Mobile & Backup Power
Mobile & behind the meter power without the risk of downtime from complex Tier IV treatment systems.
Schools & Public Infrastructure
Deploy modular air scrubbing during wildfire events or air quality crises. Provide up to 5x better indoor air quality without a major retrofit.
