Altamont Landfill and Resource Recovery Facility is located at 10840 Altamont Pass Road in Livermore, California. The facility serves as an important part of the Bay Area’s waste-disposal and resource-recovery infrastructure, receiving waste from communities throughout the region while also supporting organics processing, special-waste management and renewable-energy activities.
The historical WM Northern California/Nevada page identified the site simply as Altamont Landfill and described it as a Subtitle D-approved facility providing Class II and Class III disposal. That historical facility entity, address and disposal intent remain strongly aligned with current official WM information.
Altamont is particularly relevant to the broader Bay Area waste-management network, including its relationship with the Davis Street Resource Recovery Complex and Transfer Station in San Leandro, where residual trash is consolidated before being transported to Altamont for final disposal.

What Is Altamont Landfill?
Altamont is more than a simple municipal garbage dump.
Current WM information describes it as an Altamont Landfill and Resource Recovery Facility, combining final disposal with other material-management and sustainability operations.
A regional landfill receives material that cannot be appropriately reused, recycled, composted or managed through another recovery pathway. Different waste categories can require different approval, preparation or receiving procedures.
The basic regional relationship is:
Home / Business / Project
→ Collection or Self-Haul
→ Recycling / Transfer / Recovery where appropriate
→ Altamont Landfill for qualifying residual material
For example, material received at Davis Street in San Leandro can first undergo reuse, recycling or composting recovery before residual trash is transferred to Altamont.
What Areas Does Altamont Landfill Serve?
Current WM information states that Altamont accepts disposal waste from the nine Bay Area counties:
- Alameda County
- Marin County
- Sonoma County
- Napa County
- Solano County
- Contra Costa County
- San Mateo County
- San Francisco County
- Santa Clara County
WM’s current facility information further distinguishes between disposal tonnage originating in Alameda and San Francisco counties and certain waste streams originating in the other seven Bay Area counties. Commercial and special-waste customers should therefore confirm origin and material requirements before arranging disposal.

What Materials Does Altamont Landfill Currently Accept?
This is one section where current information should take priority over the much broader archived accepted-material directory.
Current official WM information specifically identifies the following categories:
- Municipal solid waste
- Construction and demolition debris
- Yard waste for composting
- Biosolids
- Auto shredder residue
- Sludge
- Industrial and special waste
- Certain drum-managed liquids and solids
- Friable and non-friable asbestos under special requirements
Material acceptance is conditional. Some waste streams require profiles, appointments, special packaging, regulatory documentation or advance approval.
Municipal Solid Waste
Municipal solid waste (MSW) refers broadly to ordinary non-hazardous trash generated by homes, businesses and institutions.
Current Altamont information specifically identifies municipal solid waste among accepted disposal categories.
Before sending material as general trash, users should first determine whether part of the load can instead be:
- Reused
- Recycled
- Composted
- Donated
- Managed through a specialized recovery program
The archived page likewise treated MSW as only one material stream among several available waste-management pathways.
Construction & Demolition Debris
Altamont currently accepts qualifying construction and demolition debris (C&D).
C&D waste can be generated from:
- Building construction
- Home remodeling
- Demolition
- Roofing work
- Commercial renovation
- Property redevelopment
- Infrastructure projects
The archived Altamont page associated C&D with materials such as concrete, brick, lumber, roofing materials, insulation, plastics and metals.
Where recycling is practical, recoverable construction material should be separated before final disposal. A mixed demolition load may be handled differently from source-separated concrete, metal or clean wood.
Clean Concrete
The historical Altamont page specifically listed clean concrete as an accepted-material entity and defined it as concrete free of contaminants such as soil, organic matter and chemicals.
Your recovered Clean Concrete page therefore has a historically legitimate semantic relationship with Altamont.
However, current official Altamont service information categorizes construction material more broadly as C&D debris rather than separately advertising clean concrete as its own current public category.
For that reason, users transporting a source-separated concrete load should confirm current classification, pricing and preparation requirements before arrival.
Yard Waste & Organics
Altamont currently identifies yard waste for composting among its accepted material streams.
This is particularly important because the facility also operates an industrial-scale composting system.
Current WM information states that Altamont operates Alameda County’s first industrial Covered Aerated Static Pile (CASP) composting facility and can process up to 500 tons per day of residential green waste co-collected with food waste.
Organic streams can include qualifying:
- Yard trimmings
- Leaves
- Grass
- Tree trimmings
- Food-related organics accepted by the applicable program
This creates an important semantic distinction:
Organic material → composting
instead of:
Organic material → landfill disposal
Current WM information notes that green waste and residential food scraps diverted from landfill are used in the production of compost.
Internal Link: [Organics & Composting]
Municipal Trash vs. Organics
Users should not assume that everything arriving at Altamont follows the same disposal pathway.
Ordinary non-hazardous residual waste may go to landfill disposal, while suitable green and organic material can enter a composting operation. Current official pages separately identify both MSW disposal and yard-waste composting.
Separating organics before disposal helps keep potentially recoverable material out of the landfill stream.
Industrial & Special Waste
Current Altamont services include qualifying industrial and special waste.
These materials differ from normal household garbage because their physical, chemical or regulatory characteristics may require:
- Waste characterization
- Generator documentation
- Advance approval
- Laboratory analysis
- Special transportation
- Specific unloading procedures
- Different pricing
The archived facility page also included industrial and special waste within its accepted-material taxonomy.
Businesses should not arrive with special waste without first confirming whether the load meets current facility requirements.
Soil & Contaminated Material
The historical Altamont page separately identified clean soil and contaminated soil, demonstrating that soil classification was an important part of the original facility’s semantic footprint.
Clean soil was historically distinguished from material affected by petroleum products, pesticides, heavy metals or other contamination. Contaminated soil was described as requiring specialized management based on the nature and extent of contamination.
Current public Altamont service information does not reduce all soil into one simple consumer drop-off category. Anyone transporting excavation soil—particularly from a commercial, industrial or potentially contaminated site—should confirm profiling and acceptance requirements beforehand.
Internal Link: [Soil & Contaminated Material Disposal]
Asbestos Disposal at Altamont
Altamont is unusual compared with many ordinary disposal facilities because current WM information specifically identifies friable and non-friable asbestos among materials handled under special requirements.
The archived facility page also included both asbestos categories and stated that asbestos material should be appropriately bagged or boxed, with historical receiving hours restricted to designated weekday periods.
Current WM guidance notes that asbestos is considered hazardous waste by the State of California and requires special handling.
Therefore, asbestos should never be treated like ordinary C&D debris.
Before transporting asbestos:
- Confirm the exact asbestos type.
- Obtain any required approval.
- Follow packaging requirements.
- Verify receiving days and hours.
- Follow applicable transportation and documentation rules.
Do not rely on the archived receiving schedule for a current asbestos load.
Internal Link: [Asbestos Disposal Guide]
Biosolids & Sludge
Current Altamont service information includes biosolids and sludge among facility waste streams.
The archived site also treated biosolids and sludge as separate accepted-material entities.
These are specialized commercial or municipal waste streams rather than ordinary residential self-haul material. Advance coordination and material-specific requirements may apply.
Auto Shredder Residue
Auto shredder residue (ASR) is another material specifically included in current Altamont service information.
The archived page described ASR as the non-metal material remaining after vehicles are shredded and recyclable metals are separated, potentially including plastics, rubber, foam, glass and other components.
Because ASR is an industrial waste stream, generators should follow current Altamont profiling and approval requirements rather than treating it as ordinary trash.
Appliances
The archived Altamont page listed both appliances with refrigerants and appliances without refrigerants among accepted materials. Historical examples included refrigerators, freezers and air-conditioning equipment in the refrigerant-containing category, and washers, dryers, ovens and water heaters in the non-refrigerant category.
That historical relationship is worth preserving for semantic recovery.
However, current official Altamont’s main service summary does not separately advertise household appliance drop-off in the same way.
Users should therefore confirm current appliance disposal requirements and consider appliance recycling before choosing landfill disposal.
Internal Link: [Appliance Disposal & Recycling]
Mattresses & Box Springs
The archived Altamont facility page explicitly included mattresses and box springs among accepted materials.
This gives your already recovered /accepted-materials/mattresses-and-box-springs/ page a strong historical reason to link to Altamont.
California now has dedicated mattress-recycling pathways, so users should investigate available reuse or recycling before treating an unwanted mattress as ordinary landfill waste.
Because current Altamont’s main accepted-material list does not separately advertise consumer mattress drop-off, current acceptance and rates should be verified before transport.
Metals & Tires
The old Altamont page contained historical accepted-material relationships for metal, mixed metals, car tires, truck tires and tractor tires.
Those entities should remain in the page’s historical/topical footprint without automatically being presented as unrestricted current public drop-off categories.
Metal and tires frequently have recycling alternatives, and users should consider an appropriate recovery option before landfill disposal.
Clean Wood & Other Wood Waste
The historical Altamont page included:
- Clean wood
- Painted wood
- Stained wood
- Treated wood
These materials are not equivalent.
Clean untreated wood can have recovery potential, while painted, stained or chemically treated wood may require different handling depending on coatings or preservatives.
Current Altamont also operates organics and resource-recovery activities, but users should confirm which wood stream applies before transporting a load.
Historically Listed Accepted Materials
The archived Altamont page had a much larger accepted-material taxonomy than the current simplified public service summary.
Historical entities included:
- Appliances with refrigerants
- Appliances without refrigerants
- Friable asbestos
- Non-friable asbestos
- Biosolids
- Clean concrete
- Construction and demolition debris
- Clean soil
- Contaminated soil
- Mattresses and box springs
- Metal
- Mixed metals
- Sludge
- Car tires
- Tractor tires
- Truck tires
- Auto shredder residue
- Green and organic waste
- Industrial and special waste
- Liquid waste
- Municipal solid waste
- Clean wood
- Painted wood
- Stained wood
- Treated wood
Important: this archived list should not be turned into a blanket statement that every material is currently accepted from every customer.
Current official service information explicitly confirms a narrower set of public-facing categories and places special conditions on materials such as asbestos, industrial/special waste and liquid/solidification drums.
That distinction is important for both user safety and SEO accuracy.
Materials Historically Listed as Not Accepted
The archived page also had a separate Not Accepted section, demonstrating that the old facility page was intended to help users distinguish between ordinary disposal and materials requiring another pathway. Historical examples included ash, cardboard, carpet, mixed concrete, mixed soil and other specialized materials.
Because the present-day facility classification may differ, users should rely on current Altamont acceptance requirements, not the archived yes/no taxonomy, when planning a disposal trip.
Altamont & Davis Street: How the Facilities Connect
One of the strongest internal-link relationships on this recovered site is:
Davis Street Resource Recovery Complex → Altamont Landfill
Current WM information states that Davis Street in San Leandro is designed to recover materials for reuse, recycling and composting while facilitating the transfer of residual trash to Altamont in Livermore.
This creates a clear semantic facility relationship:
Alameda County waste
→ Davis Street recovery and transfer
→ recover recyclables/organics
→ residual waste
→ Altamont Landfill
Therefore, both facility pages should link contextually to each other.
Altamont Composting & Resource Recovery
Altamont’s role extends beyond final disposal.
Current WM information identifies the facility’s Covered Aerated Static Pile composting operation as capable of processing up to 500 tons per day of residential green waste co-collected with food waste.
This gives the facility an important topical relationship with:
- California organics diversion
- Food scraps
- Green waste
- Compost
- Resource recovery
- Sustainable material management
Current WM information also states that organic material diverted at the facility returns to use as compost rather than simply being buried as waste.
Landfill Gas & Renewable Energy
Modern landfills generate gas as organic material breaks down.
Current WM information states that Altamont uses a network of extraction wells and vacuum systems to capture landfill gas and convert it into renewable energy, with remaining gas managed through controlled flaring.
This creates another important semantic relationship:
Landfill waste → landfill gas → gas capture → renewable energy
It also helps distinguish Altamont from a generic “dump” page and reflects the facility’s broader resource-management role.
Environmental Protection at Altamont
Current official WM environmental information states that Altamont uses engineered systems including:
- Landfill liners
- Leachate collection
- Groundwater monitoring
- Landfill-gas collection and control systems
WM also states that nearly 1,000 acres of the 2,170-acre property are designated as a wildlife preserve under a habitat conservation easement, with an additional buffer area separating active operations from neighboring properties.
These environmental systems belong on the recovered page because they expand the entity beyond “garbage disposal” into landfill engineering, groundwater protection, gas management and habitat conservation.
Altamont Wildlife Preserve
The facility’s current environmental program includes a substantial wildlife-preserve component. WM reports that nearly 1,000 acres are designated for conservation under agreements involving federal and state agencies.
For semantic SEO, this creates relevant—not forced—relationships between:
Altamont Landfill → environmental stewardship → habitat conservation → Bay Area
The content should remain factual rather than using vague sustainability marketing language.
Altamont Landfill Rates
Altamont currently maintains a 2026 accepted-materials and rates document through its official facility site.
Rates can vary by:
- Waste type
- Weight
- Minimum charge
- Special handling
- Profiling requirements
- Customer/account type
Because rates change, publishing copied dollar amounts directly into the recovered evergreen page can create unnecessary maintenance risk.
A better approach is:
Check the current facility rate sheet before visiting.
This keeps the page useful without allowing old pricing to become stale.
Load Inspections & Facility Safety
Current Altamont facility information states that random load checks are conducted, and illegal disposal can lead to further action and cost recovery. It also prohibits scavenging of disposed materials.
Before arriving:
- Secure your load.
- Know what materials are in it.
- Keep prohibited material separate.
- Carry required documentation for special waste.
- Follow employee instructions.
- Be prepared for inspection where applicable.
Commercial generators should be particularly careful to properly classify and document special materials before transport.
Before Visiting Altamont Landfill
Before making a trip to Altamont:
- Identify your waste type. Determine whether it is MSW, C&D, organics, asbestos, special waste or another category.
- Check whether recycling or composting is preferable.
- Confirm current acceptance. Some archived accepted-material categories may not match current public receiving rules.
- Confirm special-waste approval requirements.
- Check current public hours.
- Review the latest rate sheet.
- Confirm special receiving windows for materials such as asbestos or drum-managed waste.
- Secure the load.
- Keep hazardous or incompatible material separate.
- Follow load-check and safety instructions.
Current official information confirms that different material categories have different handling requirements, making advance identification especially important at Altamont.

Bay Area Waste Disposal & Resource Recovery
Altamont Landfill plays a significant role in the Bay Area’s broader material-management system.
Its relationship with transfer facilities such as Davis Street, its acceptance of municipal and construction waste, its organics-composting operations and its landfill-gas recovery infrastructure create a much broader topic than simply “where to dump trash.”
For residents, businesses and contractors, the key is to choose the correct pathway before arriving:
Recyclable material → recycle
Organic material → compost where eligible
Reusable material → reuse/donate
Special material → verify approval
Residual qualifying waste → disposal
