Waste hauler Republic Services is preparing to open one of the nation's largest composting and mulch processing facilities this fall in El Mirage, a Mojave Desert community where Joshua trees outnumber residents. the $90 million San Bernardino Sustainability Park, built on a former dairy farm that sold its water rights nearly two decades ago, will help Southern California cities comply with state mandates to reduce green waste sent to landfills, according to the source report.

Why a $90 Million Composting Facility Chose a Ghost Town Named El Mirage

The location, about 15 minutes north of Phelan off State Route 138, might seem improbable: a tiny desert hamlet with a fraction of the population of the cities it will serve. But the source article notes the property was previously a dairy farm that folded after the owner realized selling water rights to a thirsty local government entity was more profitable than milking cows.. The land was already zoned for agricultural use, and the existing infrastructure — including a farm scale — made it easier to convert into an organics processing site. The facility is fully permitted and will take in green waste from Southern California communities that need to meet the state's ambitious recycling targets.

From Dairy Farm to Green Waste Hub: The Water Rights Trade-Off

The source reports that the original dairy farm sold its water rights to a local government entity, a deal that underscores a recurring tension in the arid West: the value of water versus the value of land. Republic Services is now repurposing the acreage for waste processing, but the faciilty sits near the California Aqueduct, and stormwater runoff pools are part of the site's design. Chris Seney, Republic Services' director of organics operations, discussed the facility with the Wrightwood Community Service District board member Rick Christensen, as reported. The water rights transaction from two decades ago means that whatever water remains on the property is now managed by an outside agency — a detail that could complicate any future efforts to expand the composting operation or mitigate dust, a common concern at dry desert facilities.

How California's Green Waste Mandates Drove Republic Services' $90 Million Bet

California's Senate Bill 1383, which took effect in 2022, requires jurisdictions to reduce organic waste disposal by 75% from 2014 levels. The source makes clear that Republic Services' facility is a direct response to that regulatory pressure. Municipalities from the San Gabriel Valley and beyond will send green waste to El Mirage, where it will be turned into compost and mulch. The $90 million price tag — one of the largest single investments in composting infrastructure in the nation — signals that Republic is betting big on the long-term viability of the organics recycling market. The solar farm on the edge of the property, owned by a different company, hints at further energy integration, though details remain scant in the original report.

Open Questions:Who Owns the Solar Farm and What About the Local Ecology?

The source article mentions a solar farm on the edge of the San Bernardino Sustainability Park but does not name the owner or outline any power purchase agreements with Republic Services.. It also notes that Joshua trees outnumber people in El Mirage, yet offers no comment from environmental groups or local residents about the impact of heavy truck traffic, noise, or potential dust on the fragile desert ecosystem. Rick Christensen, a community service district board member, spoke favorably about the project, but no opposing voices were quoted.. These gaps leave key questions: How will the facility handle dust and odors in a dry climate? And what happens to the compost market if state mandates shift or municipal budgets tighten?
