Concrete Recycling in Saratoga: Turning Concrete Debris into Reusable Resources
Concrete recycling in Saratoga turns demolished driveways, foundations, sidewalks, and building slabs into crushed aggregate, base rock, and road fill instead of sending heavy material to a landfill. Through CALGreen, covered projects in Saratoga must divert 100% of land-clearing debris and 65% of all other C&D debris from landfill disposal, with weight tickets and diversion reports required for documentation.
GreenWaste provides debris box rentals and C&D recycling services to Saratoga homeowners and contractors, with material processed at the GreenWaste Zanker Resource Recovery Facility in San Jose. The facility diverts up to 75% of incoming material, well above CALGreen’s 65% threshold.

Why Saratoga Projects Recycle Concrete
Meeting CALGreen Diversion Requirements
Saratoga follows California’s CALGreen building standards through the West Valley Solid Waste Management JPA, which also covers Campbell, Los Gatos, and Monte Sereno. Projects must divert 65% of C&D debris from landfills, and concrete is typically the heaviest single material stream in a demolition. Recycling it is one of the fastest ways to reach that 65% threshold.
Weight tickets from certified facilities serve as compliance documentation. GreenWaste provides detailed recycling reports showing tonnage collected and diversion percentages achieved, satisfying CALGreen requirements for building permit files.
Cost Advantages Over Landfill Disposal
Bay Area landfill tipping fees continue to rise, 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 Recycled Class II Base Rock. The cleaner the load, the better the rate.
Using recycled concrete aggregate as base material also costs less than purchasing virgin rock. The savings work on both ends: lower disposal costs and lower material procurement costs for the next phase of a project.
Keeping Materials Local
Every ton of recycled concrete replaces aggregate that would otherwise need to be quarried. GreenWaste processes concrete at its San Jose facility, keeping the material in the regional supply chain rather than requiring imports from distant quarries. Peer-reviewed research on recycled concrete aggregate production has found carbon emission reductions of roughly 20% to 40% compared to virgin aggregate extraction, depending on transportation distances and processing methods (EPA overview of C&D recycling benefits).
Where to Recycle Concrete Near Saratoga
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 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, with industrial crushers, magnetic separators, and multi-stage screening that produce clean, graded aggregate. 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.
Residential customers can bring concrete directly to the facility during operating hours with no appointment needed. Concrete weighs roughly 150 pounds per cubic foot, so even a small volume adds up fast. For anything beyond a few broken sections, a debris box rental is more practical than self-hauling.
GreenWaste Hayward Transfer Station
GreenWaste also operates the Hayward Transfer Station in Alameda County, which processes up to 175 tons per day of C&D material. This facility provides additional Bay Area capacity for source-separated concrete from driveways, building pads, road construction, and demolition projects.
What Concrete Can Be Recycled?
Nearly all concrete is recyclable at GreenWaste’s facilities. Foundation and structural concrete, driveway and sidewalk slabs, concrete block and CMU, and concrete with embedded rebar are all accepted. GreenWaste’s processing systems extract rebar and wire during the crushing process, and the separated steel is recycled through scrap metal channels.
Concrete heavily contaminated with asphalt, wood, or trash needs sorting before processing. Clean loads move through the system faster and qualify for better rates. Concrete containing hazardous materials requires specialized disposal and is not accepted. When possible, separating concrete from other demolition debris on site before loading improves processing efficiency. Contact GreenWaste for guidance on load preparation and material requirements for your project.
Debris Box Rentals for Saratoga Concrete Projects
GreenWaste provides debris box rentals to Saratoga 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. All concrete collected through Saratoga debris box services is processed at GreenWaste’s certified facilities with full documentation for permit compliance.

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. Its angular particle shape provides strong compaction and interlocking characteristics, making it a structurally sound alternative to virgin aggregate.
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 purchase and delivery throughout the Bay Area.
Common Applications
Recycled concrete aggregate from GreenWaste 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. California transportation agencies routinely specify recycled aggregate for highway and road construction.
