Yes. Place your shredded paper in a clear plastic bag, tie it securely and place it in your blue recycling cart. You may also use a paper bag.

Residents are encouraged to donate items that are reusable. If items are not reusable, the Clean Up Day program provides you with curbside collection.

Goodwill and Salvation Army accept unusable clothing (e.g., torn, stained clothing). They sell it to a cloth recycler to be made into rags.

Most types of plastic, with or without a number, are accepted in your blue recycling cart. This includes bottles, containers, film plastics (e.g., plastic bags, dry cleaning bags and bubble wrap) and rigid plastics (e.g., broken toys, shelving, laundry baskets and container caps/lids). There are some exceptions such as plastic foam. Additionally, film plastics must be bundled together inside a clear plastic bag. Learn more about What Goes Where at www.cityofpaloalto.org/wgwtools

Although it is technically possible to recycle expanded polystyrene, there are no viable, cost-effective markets currently available for this material. There are no recycling markets for other types of plastic foam.

Loose plastic film and plastic bags get tangled in the sorting equipment at the recycling facility. Placing it in a clear bag makes it easier to spot and pull off the conveyor belt at the beginning of the process.

No, you do not need to wash or rinse your recyclables – you just need to pour out liquids, scrape out food, and wipe out oily or sticky residue. A rule of thumb is if you turn over your container and shake it a bit (opening facing down) and nothing comes out, it’s clean enough for your recycling cart. View our Residue video for more information

Although it is technically possible to recycle juice boxes and other aseptic containers, we do not accept them in our program because it is not economically feasible at this time. Only a few paper mills are capable of recycling them. If we were to add aseptic containers to our recycling program, Green Waste would have to either separate them out at their sorting facility (which requires special machinery and storage space) or the containers would get included into the mixed paper. If they were in the mixed paper, GreenWaste would have to limit their marketing options only those mills capable of recycling aseptic containers instead of marketing it to get the best price.

Yes! Our recyclables are getting recycled. Please continue to recycle. The recycling market has changed significantly in the couple of years since China restricted the materials they accept for processing. The City is addressing the current recycling challenges in a multi-pronged approach – outreach to reduce contamination of recycling materials; creating policies to reduce waste; and directing GreenWaste to improve materials separation and utilize domestic markets when available, and to improve tracking of where materials are ending up.  

The good news is that GreenWaste has been able to find new markets for the items China no longer accepts. And in response to our request to prioritize domestic markets, GreenWaste was even able to secure domestic markets for all our plastic except film plastic and for cardboard. Film plastic and mixed paper is still going overseas and there is a current market and demand for these materials.

So recycling is still feasible and we definitely want to encourage recycling. That said, it is even better to avoid creating waste in the first place. While recycling is good, reducing and reusing items is MUCH better.

Yes! All food scraps should be put in your green cart including bones, meat, dairy, fruit, vegetables, grains, dough, coffee grounds and filters, teabags and other plate scrapings. You can place food scraps and soiled paper loose or bagged with compostable bags in your green cart.

Yes! Soiled paper products can be put in your green cart including paper towels, napkins, tissues (yes, even your used tissues can be composted), pizza boxes, paper plates and cups, paper take-out containers, food and beverage cartons, and food soiled paper/cardboard packaging. They can be placed directly in your green cart.

Yes! You can place compostable plastic products that are clearly labeled ‘Compostable’ in your green cart. This includes clamshell containers, cups, utensils and bags. Products that are labeled ‘Biodegradable’ are not accepted because they do not break down fast enough during the composting process.

We strongly discourage using your kitchen sink grinder/garbage disposal to dispose of your food scraps. By placing your food scraps in your green compost cart you:

• Reduce sanitary sewer system blockages and expensive repairs resulting from sewer backups into homes or onto streets. Food scraps sent down the drain often contain fats, oils, and grease that are the cause of most residential sanitary sewer backups.
• Conserve water. Several gallons of water are required to flush food scraps down the drain. In Northern California, where water resources are scarce, this is not the best use of water.
• Reduce household energy use and maintenance costs. Grinders/disposals require and electrical connection and, like any other machine with moving parts, may break down and require professional repair.
• Generate energy. Food scraps collected in the green carts will be anaerobically digested, creating methane that is then combusted to generate electricity.
• Create a usable product. Food scraps collected in the green carts will produce energy and then becomes compost, which will provide nutrients to the soil for growing plants.

Yes, small amounts of oil or grease from household cooking are allowed. Use paper towels or other compostable items to absorb them and place them in your green compost cart. Bring large amounts of unwanted cooking oil to the Household Hazardous Waste Station.

Absolutely. Backyard composting provides an on-site sustainable solution for many types of food scraps, like fruit and vegetable peelings and ends. Soiled paper such as paper towels, coffee filters, and tea bags are also suitable for home composting. Food scraps that are not appropriate for backyard composting, like meats, cheeses, eggs, oils, and bones, can be placed directly into the green cart. Soiled paper products such as paper takeout containers, paper plates, and used tissues, which are not appropriate for backyard composting, should go into the green cart.

Free home composting workshops are offered by Santa Clara County. Palo Alto residents that attend one of these workshops can receive a free compost bin. Learn more on our Home Composting page.

The compostable material collected in your green cart is taken to the Zero Waste Energy Development Company (ZWED) in San Jose, where it is anaerobic digested and composted. This process yields both renewable energy and compost which is used to enrich the soil.

There are a number of different ways you can make compost collection easy and convenient without smells or bugs. Palo Alto residents have shared their tips on what works for them at www.cityofpaloalto.org/foodscraps. Here are a few tips for indoor storage:

• Empty your kitchen bucket into your green compost cart regularly – about every two to three days. 
• Line your kitchen bucket with a compostable bag, wrapping messy food scraps in newspaper or utilizing used paper towels to soak up moisture before placing in the bucket.
• Sprinkle baking soda or spray vinegar inside the bucket to reduce odors. 
• Wash your bucket with soapy water or in your dish washer. 
• Place your bucket (or other preferred collection container) in your freezer to avoid food from decomposing before placing the materials into your green compost cart for collection.

Yes, you can use compostable plastic bags. When purchasing them, look for bags that are clearly labeled “Compostable” or “BPI certified” (Biodegradable Products Institute.) Bags labeled as simply 'Biodegradable' are not accepted because they do not break down fast enough in the composting process. Plastic garbage bags and single-use plastic bags are not accepted.

For a comprehensive list of certified brands and products, visit the BPI catalog

You can find compostable plastic bags at a number of local stores. The most common brands include: BioBag, If You Care, Ucan Untrash, Glad compostable, Bag-to-Nature, and EcoSafe. These bags are generally available in 3 sizes:

• 2.5 to 3 gallons – these fit in your kitchen bucket
• 13 gallons – these are the standard ‘tall kitchen trash bag’ size
• 30 to 40 gallons

If you prefer to buy online, many e-commerce websites offer a wide range of certified compostable bag brands in bulk.

Here are some tips to keep your green cart clean:

• Use newspaper, paper milk cartons, compostable bags or other compostable items to containerize your food scraps before placing them into your green cart.
• Place food scraps in between layers of yard trimmings within the green cart.
• Sprinkle baking soda into your green cart.
• Keep the green cart in the shade on hot days.
• Rinse out your green cart as needed. Pour dirty water onto grass or gravel. Never pour the dirty water on your driveway or down the storm drain. The dirty water going down the storm drain flows directly to our waterways and could negatively impact fish and other wildlife in the creeks and Bay.

Placing food scraps in the green cart is no different than placing food scraps in the black cart as garbage. The green carts are made from a heavy-duty plastic and are designed to remain upright. If you have additional concerns, place the food scraps in compostable bags or containers (e.g., milk carton, ice cream carton). They will keep the food scraps contained and reduce the odors emitted from the food scraps.

Events are held every Saturday from 9am-11am and on the first Friday of each month from 3pm-5pm. The events are held at the Regional Water Quality Control Plant (RWQCP) located at 2501 Embarcadero Way, Palo Alto.

Unwanted hazardous household products such as used or expired medication, paints, solvents, fuels, cleaners and pesticides are accepted. A larger list of accepted items is available on our Hazardous Waste Program page.

No gas cylinders (camping & BBQ propane tanks are ok); radioactive wastes; wastes containing body tissues or body fluids; controlled substances; electronics; motor oil; antifreeze; car batteries; explosive wastes (marine flares); and ammunition. A larger list of accepted items is available on our Hazardous Waste Program page.

Residents can only transport up to 15 gallons or 125 pounds of household hazardous waste at any time. However, residents can make more than one trip to the HHW Station.

Businesses or non-profit organizations located in Palo Alto, East Palo Alto, Mountain View, Stanford, Los Altos and Los Altos Hills that generate less than 220 pounds of hazardous waste per month can participate in Palo Alto's Conditionally Exempt Small Quantity Generator Program.

If you find this occurring regularly, contact GreenWaste Customer Service at (650) 493-4894 or pacustomerservice@greenwaste.com to order a larger recycling cart at no additional cost. If this only occurs on occasion, you may place your additional recyclables in a paper bag next to your recycling cart. Additional cardboard should be flattened and cut into pieces no larger than 2’x 3’,tied and placed next to your cart.

If you find this occurring regularly, contact GreenWaste Customer Service at (650) 493-4894 or pacustomerservice@greenwaste.com to order a larger compost cart. Up to 3 carts are available to residents for no charge; additional carts will be available for a nominal fee. If this only occurs on occasion, you may place your additional yard trimmings in a compostable container, such as 30 gallon Kraft paper bag, cardboard boxes or in bundles (no larger than 2’x 4’) next to your wheeled cart. These containers/bundles may not exceed 40 pounds and will not be returned.

Scavenging recyclables at the curb is prohibited by City ordinance. If you see someone other than GreenWaste employees collecting your recyclables, obtain the vehicle’s license number and description and report it to the police department immediately at (650) 329-2413.

Residents who generate minimal waste may be able to save money by reducing their garbage service level to the 20 gallon mini-can. If you are interested in subscribing for mini-can service, please contact GreenWaste Customer Service at (650) 493-4894 or pacustomerservice@greenwaste.com

To ensure collection of your landfill (i.e., garbage), recycle and compost, place carts curside by 6 AM on your collection day, close all lids - please do not overfill and place front of cart facing the street. Sometimes your garbage may be picked up later due to substitute drivers, traffic or route changes. If your garbage is still not collected by 4 PM on your normal collection day, please contact Customer Service at (650) 493-4894 or pacustomerservice@greenwaste.com

Contact GreenWaste of Palo Alto at (650) 493-4894 or pacustomerservice@greenwaste.com to start refuse services. If you need assistance with recycling, composting, or other zero waste measures, a GreenWaste Environmental Outreach Coordinator (EOC) can assist you, at no additional cost. Assistance includes:

• Establish service levels, conducting site visits and waste audits
• Planning for special events
• Educating employees on how to properly sort their waste with EOC on-site training and meetings
• Posters and stickers
• Tours of our processing facilities

All material should be sorted properly and placed inside the appropriate service containers. If you occasionally have extra material, please do not stack it on the ground, call GreenWaste to schedule an extra collection. If you regularly have extra material, please call GreenWaste to increase the size of your container or frequency of pick-ups. Please also note that lids must close on your containers at all times or you may incur extra charges. By keeping all material inside the appropriate containers, you are also helping keep Palo Alto clean and litter-free, which helps prevent litter from getting into our local creeks and the Bay.

To keep your compost and garbage bins odor free, remember to bag and tie the materials when you take them to your outdoor bin. You can also request bin wash service from GreenWaste (for a fee).

Yes, both are compostable. Here is a detailed list of accepted materials or contact GreenWaste Customer Service at (650) 493-4894 or pacustomerservice@greenwaste.com. The exception to this rule is Yard Trimmings debris box service where only yard trimmings are allowed.

Reducing the total volume of materials set out for collection by using the 3Rs (reduce, reuse, recycle/compost) is the best way to reduce your bill.

• Reduce – Eliminate disposables and purchase items with no or recyclable packaging.
• Reuse – Give, donate, or sell reusable items utilizing local reuse organizations and internet resources.
• Recycle – Participate in the recyclables collection program.
• Compost:
  • Reduce the amount of yard trimmings generated on your property by replacing high maintenance landscape (e.g., turf, landscape requiring constant trimming) with native plants.
  • If possible, compost on your premises.

Scavenging recyclables is prohibited by City ordinance. If someone other than GreenWaste is collecting your recyclables, obtain the vehicle license number and description and contact the Police Department immediately at (650) 329-2413.

The Ordinance requirements are:

• Everyone in Palo Alto is required to place their discards in the correct container designated for that type of material – black carts or tan bins for landfill (i.e., garbage), blue for recycle (e.g., plastic, glass, metal, paper), and green for compost (e.g., yard trimmings, food scraps, soiled paper).
• Any entity with garbage service in Palo Alto also must subscribe to recycle, and compost collection service from GreenWaste of Palo Alto, the City’s contract hauler.
• All building tenants, including residents of multifamily complexes, must have access to landfill (i.e., garbage), recycle, and compost collection containers.
• All locations where a business’ customer, employee, or visitor may need to discard materials need to have containers for solid waste, recycle, and compost. Examples include: in a dining room area for a fast-food restaurant, a lobby, and a kitchen or lunchroom in an office building.

The City and GreenWaste will provide kitchen food scraps collection buckets for residents of multifamily complexes. Additionally, City staff and GreenWaste Environmental Outreach Coordinators (EOCs) will work with businesses to identify the optimal locations for internal solid waste, recycling, and compost containers and provide signage, but will not provide internal containers.

The entity that pays for refuse service is responsible for the material found within the collection containers. The City and GreenWaste will work with property managers and landlords to provide training and appropriate signage to help tenants sort their discards properly.

If you are experiencing problems with other people using your collection containers, they can be equipped with locks to eliminate the ability for anyone other than the key holder to use the collection containers.

There is no specific or numeric threshold to determine contamination. Sorting waste perfectly can be challenging. Contamination will be monitored by both GreenWaste truck drivers as part of regular collection and GreenWaste Environmental Outreach Coordinators (EOCs) through random site visits. If the GreenWaste truck driver or EOC identifies obvious contamination, the container would be considered contaminated. Contaminated containers will be addressed in a multi-step procedure, fees and fines may be incurred.

Regular monitoring of contamination in the landfill (i.e., garbage), recycle, and compost containers will be done by the drivers during collection. City staff or GreenWaste staff may perform periodic checks to determine if the customers are in compliance with the ordinance.

Compostable plastic bags provide the best defense against compostable materials from becoming an odor or bug issue. Be sure to empty internal compost containers at least every two to three days. Rinse your internal compost containers periodically as needed.

The material in the compost containers has always been a component of your waste. If you did not have issues with vectors when you put compostable materials, e.g., food scraps or paper towels, into the landfill (i.e., garbage) containers, you should not have issues with moving that same material to a different colored container. It may help to contain compostable materials in a compostable plastic bag. Make sure to keep the lids of the collection containers closed at all times. Should the compost collection containers need to be cleaned, GreenWaste offers a bin wash service for a small fee.

Deconstruction is the systematic and careful dismantling of a structure, typically, in the opposite order it was constructed, to maximize the recovery of materials for reuse and recycling.

Deconstruction is an environmentally friendly alternative to demolition, it involves buildings or structures being systematically taken apart thereby allowing materials to be kept unbroken and separated, making it easier to reuse and recycle. This differs from traditional demolition, where an excavator knocks down a whole building with all the materials within the structure being smashed and combined into a container.

Despite Palo Alto’s already high recycling rate for construction projects, approximately 44% of what Palo Alto sends to the landfill comes from construction and demolition projects. The City is requiring deconstruction to recover valuable building materials that would have been destroyed by traditional demolition. Deconstruction attains a higher end use for building materials, reduces the amount of waste going to landfills, conserves natural resources, reduces greenhouse gas emissions, and encourages Zero Waste.

Reuse is further or repeated use of materials or items in their current form, including sale or donation of items. It is different from recycling which is breaking down used items to make raw materials for the creation of new products. Some materials commonly salvaged for reuse include lumber, fixtures, doors, cabinets, appliances, and bricks.

Demolition will no longer be allowed. Projects where structures are being completely removed (previously referred to as “demolition”) are required to conduct a survey designating the materials to be salvaged for reuse, deconstruct the structure, and source separate materials for reuse and recycling.

Deconstruction, salvage for reuse, and source separation requirements are effective July 1, 2020. Building permit applications submitted on or after this date will be subject to these new requirements.

The new deconstruction ordinance requires projects where structures are being completely removed to conduct a survey designating the materials to be salvaged for reuse, deconstruct the structure, and source separate materials for reuse and recycling.

Residential and commercial projects where structures are being completely removed, formerly known as demolition, must comply with the requirements.

All deconstruction materials are required to be sorted onsite into specific categories.

• Materials for reuse – These materials were designated as salvageable in the Salvage Survey. They are to be packaged and delivered to a City approved reuse facility by the project contractor.
• Materials for maximized recycling – These materials are to be separated into specific categories (e.g., obtain separate containers provided by GreenWaste of Palo Alto for sheetrock, clean wood, etc.) and delivered to one of the City approved materials recovery facilities listed in Green Halo.

Some of the categories for source separation of material include: 

• Concrete (e.g., asphalt pavement, bricks/stones, gravel, porcelain, etc.)
• Wood Waste (e.g., unpainted wood/ lumber, yard clippings/ landscaping, etc.)
• Sheetrock
• Asphalt shingles
• Carpet/padding
• Metals

For more information on ordering containers, visit www.GreenWasteofPaloAlto.com

For detailed information about the deconstruction requirements, visit www.cityofpaloalto.org/deconstruction, or refer to Palo Alto Municipal Code 5.24.

Previously, all residential whole structure removals were required to obtain a salvage survey to identify materials that were salvageable for reuse – the choice to salvage those materials was optional. The new requirements expand the salvage survey requirement to both residential and commercial whole structure removals and require certification from the reuse facility that the items listed on the salvage survey were salvaged. The salvage survey itself has not changed.

Currently, The Reuse People is the only organization allowed to perform the salvage survey and accept salvageable materials. Contact them at info@thereusepeople.org or visit www.thereusepeople.org for more information.

The list of approved reuse organizations may be expanded in the future. Staff chose to remain with the currently approved reuse organization for the launch of the new deconstruction requirements. Once there is a better understanding of the program needs and material flows, additional reuse facilities may be approved.

All deconstruction and construction projects are required to utilize GreenWaste of Palo Alto for the collection of all materials if using containers (bins or debris boxes) at project sites. Contractors can continue to self-haul material by using trucks but must still deliver materials to one of the City approved processing facilities listed in Green Halo. More information can be found at www.greenhalosystems.com

All projects using bins or debris boxes at any deconstruction or construction site are required to obtain these containers through the City’s hauler, GreenWaste of Palo Alto. Bins and debris boxes are available in multiple sizes and can be ordered on an on-call basis or as a scheduled weekly service. To request containers, contact GreenWaste of Palo Alto at (650) 493-4894 or email pacustomerservice@greenwaste.com. Additional information can be obtained atwww.greenwasteofpaloalto.com

Yes, self-haul of materials may continue if using trucks, but materials must be source separated and delivered to City approved processing facilities listed in Green Halo. More information can be found at www.greenhalosystems.com. 
Use of any containers not provided by GreenWaste of Palo Alto is not allowed.

All materials are to be delivered to one of the City approved materials processing facilities listed in Green Halo. More information can be found at www.greenhalosystems.com

Compliance with the City's Municipal Codes on deconstruction, refuse collection, and waste sorting requirements is expected. Non-compliance will result in violations and fines and may also lead to project delays.

Expanding these requirements to other construction related projects is likely, but not yet established. These new requirements help the environment and will support the City’s Zero Waste and Sustainability & Climate Action Plan goals by increasing reuse and recycling, conserving natural resources and reducing greenhouse gas emissions.

Construction waste containing asbestos, lead, PCB, etc. is considered hazardous, such hazardous waste should be identified by a qualified professional prior to the commencement of the project. Abatement by a qualified contractor must be performed to properly remove and dispose of the identified hazardous waste. During deconstruction, if additional hazardous materials are identified, additional abatement must be performed. More information can be found atwww.baywise.org/demolition
