Concrete Recycling in Los Gatos: Eco-Friendly Base Rock Solutions
Construction projects in Los Gatos generate a steady stream of concrete waste, from cracked driveways and crumbling foundations to buckled sidewalks and demolished patios. Recycling that concrete keeps heavy material out of landfills, reduces demand for quarried aggregate, and produces affordable base rock for the next project.
Through CALGreen, the Town of Los Gatos requires applicable projects to divert 100% of all land-clearing debris and 65% of all other C&D debris from landfill disposal. C&D diversion reports and weight tickets must be submitted for all projects to document compliance.
GreenWaste provides debris boxes and dumpster rentals to Los Gatos homeowners and contractors, with material processed at the RCI-certified Zanker Resource Recovery Facility in San Jose. The facility diverts over 75% of incoming material from landfill, well above the state’s 65% CALGreen requirement.
Why Los Gatos Projects Recycle Concrete
Meeting CALGreen Diversion Requirements
Los Gatos follows California’s CALGreen building standards through the West Valley Solid Waste Management JPA, which also covers Campbell, Monte Sereno, and Saratoga. Projects must divert 65% of C&D debris from landfills. Because concrete is heavy and makes up a large share of demolition tonnage, recycling it is one of the most effective ways to hit that 65% threshold.
Weight tickets from certified facilities serve as your compliance documentation. GreenWaste provides detailed recycling reports showing tonnage collected and diversion percentages achieved.
Cost Advantages Over Landfill Disposal
Bay Area landfill tipping fees keep climbing year over year, and concrete is one of the most expensive materials to landfill because of its weight. Recycling clean, source-separated concrete typically costs less than landfill disposal because the recovered material has resale value as aggregate products like base rock. The cleaner the load, the better the rate.
Using recycled concrete aggregate as base material also costs less than purchasing virgin rock, so the savings work on both ends: lower disposal costs and lower material procurement costs for the next phase of your project.
Reducing Quarrying and Keeping Materials Local
Every ton of recycled concrete replaces aggregate that would otherwise be quarried. Recycling keeps processing local rather than importing aggregate from remote quarries or hauling waste to distant landfills. Research shows recycled aggregate production generates meaningfully fewer carbon emissions than extracting and processing virgin aggregate, with studies finding reductions of roughly 20-40% depending on transportation distances and processing methods.
Where to Recycle Concrete Near Los Gatos
GreenWaste Zanker Resource Recovery Facility
Location: 705 Los Esteros Road, San Jose, CA 95134
Hours: Monday through Friday: 6:00 AM to 4:45 PM Saturday: 8:00 AM to 3:45 PM Sunday: 8:00 AM to 12:45 PM Holiday hours vary. Confirm hours before visiting via the GreenWaste contact page.
The GreenWaste Zanker Resource Recovery Facility accepts concrete from residential and commercial projects. Site 1 has areas specifically designed for concrete processing. There is a $60 minimum charge per vehicle, and loads are measured by volume with no allowance for air space.
Accepted: Foundation concrete, slabs, footings, sidewalk and driveway sections, concrete with rebar (extracted during processing), concrete blocks, and precast elements.
Not accepted: Wet concrete, hazardous materials, or loads heavily contaminated with trash, wood, or other non-concrete debris.
Homeowner Drop-Off Tips
Residential customers can bring concrete directly to the Zanker Resource Recovery Facility during operating hours with no appointment needed.
Before loading: break large slabs into manageable pieces, remove obvious trash and wood, and separate concrete from other demolition debris when possible for better rates. Concrete weighs roughly 150 pounds per cubic foot, so even a small volume adds up fast. A pickup truck bed handles a reasonable load, but for anything beyond a few broken patio sections, a trailer or debris box rental is more practical.
Debris Box Rentals for Los Gatos Concrete Projects
GreenWaste provides debris box rentals to Los Gatos homeowners and contractors in three standard sizes:
10-yard box: Best for small projects and the only size that accepts heavy materials like concrete, brick, and dirt. Equivalent to roughly 3 to 4 pickup truck loads.
20-yard box: The most popular option for remodels, property cleanouts, and general debris removal. Equivalent to roughly 7 to 8 pickup truck loads.
40-yard box: Built for large-scale construction or demolition projects. Equivalent to roughly 12 to 14 pickup truck loads.
Important for concrete: Dirt and concrete must go in a dedicated box and cannot be mixed with other debris types. The 10-yard container is the only size rated for these heavy materials.
Each rental is for one week. GreenWaste delivers and picks up Monday through Saturday. Schedule a debris box delivery for your Los Gatos project here.
What GreenWaste Produces from Recycled Concrete
Recycled Class II Base Rock
GreenWaste produces Recycled Class II Base Rock from crushed recycled concrete and asphalt concrete at the Zanker Resource Recovery Facility. Caltrans Class 2 specification test results are published on GreenWaste’s website. This product is commonly used for road base, driveway foundations, parking lot underlayment, and site preparation.
Landscape and Construction Products
The GreenWaste Zanker Landscape Materials Yard at 705 Los Esteros Road sells over 90 recycled-content construction and landscape products, including aggregates, OMRI Listed compost, recycled organic mulch, soil blends, aggregate base rock, and decorative landscape materials. Products are available for pickup or delivery throughout the Bay Area.
Common Applications
Recycled concrete aggregate works well for road base and subbase, driveway and parking lot foundations, site grading and structural fill, drainage systems and French drains, erosion control, and hardscape underlayment. Its angular particle shape provides strong compaction and interlocking characteristics, making it a cost-effective and structurally sound alternative to virgin aggregate.

Frequently Asked Questions
What types of concrete can be recycled?
Foundation concrete, flatwork, structural concrete, concrete blocks, and concrete with standard rebar are all recyclable. GreenWaste’s processing systems extract rebar and wire during the crushing process. Wet concrete, hazardous materials, and loads heavily contaminated with trash are not accepted.
What are Los Gatos’s C&D diversion requirements?
Through CALGreen and the West Valley JPA, Los Gatos requires 100% diversion of land-clearing debris and 65% diversion of all other C&D debris. Weight tickets and diversion reports must be submitted for all applicable projects.
Can homeowners bring concrete to GreenWaste?
Yes. The Zanker facility at 705 Los Esteros Road in San Jose accepts walk-in drop-offs during operating hours with no appointment needed. The $60 minimum charge per vehicle applies. Call (408) 263-2384 to confirm hours before your visit.
What size debris box do I need for concrete?
Concrete and dirt must go in a 10-yard box, the only size rated for heavy materials. This holds roughly 3-4 pickup truck loads. For projects that also generate lighter mixed C&D debris, you may need a second box in a larger size for those materials. Call (888) 533-9269 for sizing help.
