Sign up for a FREE Learn to Backyard Compost Class

Spring is here, and it’s time to take your recycling and gardening efforts to the next level by learning how to compost in your own backyard! Get started today by signing up for one of Denver Recycles’ and Denver Urban Gardens’ free Learn to Backyard Compost classes. These hands-on classes will show you just how easy and fun it is to make your own compost from food scraps and yard debris such as leaves, brush, and even weeds!


Organic materials such as leaves, branches, grass clippings and food scraps make up more than half of what Denver residents send to the landfill each year. Making and utilizing compost at home is easy and it will leave you with a sense of accomplishment and some finished compost that can be used as a soil amendment around your home.

Free Learn to Backyard Compost classes begin on Sunday, May 5th and are offered through mid-October at the Denver Compost Demonstration Site (located within the Gove Community Garden on the southwest corner of 13th Avenue and Colorado Boulevard).  Each of the regular two-hour Learn to Backyard Compost classes includes an overview of composting basics, such as how to prepare organic material, how to create the proper mix of browns (carbon) to greens (nitrogen), how to properly water and turn your compost pile or tumbler, and how to troubleshoot problems. In addition to the traditional composting techniques outlined in all classes, a total of six Worm Workshop classes will focus specifically on vermicomposting (worm composting) techniques.

Registration for all classes is on a first-come, first-served basis and will open one month prior to each class date. Pre-registration is required. To sign up for classes, visit or call 303-292-9900.

Denver’s FREE Learn to Backyard Compost classes are sponsored by Denver Recycles and Denver Urban Gardens.  For more information about the many ways to compost, please visit or call 311 (720-913-1311).

A Denverite’s Guide to Celebrating International Compost Awareness Week, May 5 – May 11!

 The United States Composting Council (USCC) has declared the week of May 5 to May 11 International   Compost Awareness Week, and this year’s theme is “Cool the Climate, Compost!”

By composting once-living materials such as leaves, branches, and food scraps, organic materials are kept out of the landfill where they would otherwise break down and create a harmful greenhouse gas known as methane. Avoiding the creation of methane is one benefit of composting, but it’s not the complete picture.  When applied to soil, finished compost also kickstarts soil’s ability to store, or sequester, carbon thanks to the actions of microorganisms in the soil. Not only does composting keep harmful carbon out of the atmosphere, it also holds the key to drawing carbon down out of the atmosphere, which helps cool the climate.

  • This is a one-day event and your only opportunity to purchase discounted bulk and bagged compost from the Denver Composts program. Don’t miss out!
  • Compost will only be available at the Havana Nursery site (10450 Smith Rd., just south of I-70 on Havana St.), and only while supplies last. Compost will be available in one-cubic-foot bags for $4.00 per bag and in bulk for $35.00 per cubic yard. Complimentary compost loader service available for bulk compost purchases. There is no “dig-your-own” compost option. Limit of 20 bags or 3 cubic yards per vehicle.
  • Free mulch will be available at the Havana Nursery site and at four additional “dig-your-own” mulch satellite sites, while supplies last.  Complimentary mulch loader service available at the Havana site only.

Compost is a great soil amendment that can be used to improve soil in new construction projects, landscape renovations, backyard gardens, container gardens and even houseplants. Compost is widely recognized for its ability to improve soil structure, reduce water needs, and add soil nutrients and beneficial microorganisms. The compost sold at this event is made in part from leaves collected from last fall's LeafDrop program and from the yard debris and food waste collected through the Denver Composts program.

The mulch for this event is made from ground up Christmas trees collected through the Treecycle program, and from storm debris branches removed from Denver parks. Mulch can be applied to landscaped areas to control weeds, retain soil moisture, and protect shallow-rooted plants. 


  1. Residents must bring their own pitchfork or shovel for loading mulch, and bags or containers for transporting mulch.
  2. Residents must bring their own tarps to cover loads of mulch and/or compost in trucks and trailers.
  3. Commercial entities are prohibited from taking mulch and purchasing compost offered at this event.

Refuse & Reuse for Less Waste

Even better than recycling, the number one way to reduce waste is to not create it in the first place.  Not creating waste requires refusing disposable items, and reusing and repairing products that you already have.


There are lots of ways to stop waste before it starts.  One of the first steps you can take is to stop buying and using disposable products. Here are some examples:

1.       Bring your own reusable water bottle wherever you go.  Add water bottle to the list of items that you run through in your head before leaving the house - keys, wallet, phone, water bottle - and you’ll be on your way to making this part of your daily routine.

2.       Bring your own reusable travel mug. Most coffee shops will give a discount for providing your own mug, and your drink will stay hot longer too!  

3.       Bring your own tote bag every time you shop and say no thanks to plastic and paper shopping bags.  Most stores provide a discount for each bag you bring.  

No matter how small or insignificant an item may seem, making a product new from raw materials requires the energy-intensive and resource-intensive steps of removing material from the earth, processing it, manufacturing it into something useful, and transporting it to wherever it will be sold. All these steps require a lot of energy, and have an environmental impact. So, rather than using an item just once, it’s best to find items that can be reused.  To really make your efforts count, be sure to use your reusable fabric tote bags, travel mug and/or water bottle regularly and resist replacing them just because you like the color or logo of another reusable product better. 

Let’s put an end to single-use waste. Incorporating durable, reusable items (preferably ones you already have), into your daily routine is a great way to curb a throw-away lifestyle, save money, and prevent litter. Visit to learn more and to take the Refuse & Reuse pledge.

Save the Food! Preventing Food Waste Starts With All of Us

The Natural Resources Defense Council (NRDC) estimates that up to 40% of food in the United States is wasted. While some of this food waste occurs outside of our immediate control as part of the complex national food system, a large percent of this waste can be controlled a little closer to home. In fact, NRDC found that upwards of 40% of the food wasted in Denver was generated from households. This makes households the single largest generator of food waste in Denver, and therefore, a great location to focus on reducing food waste.


While no reasonable Denver resident would intentially throw away hundreds of dollars worth of food each year, that’s essentially what we’re all doing.  The average American family of four spends an estimated $1,800 per year on food that they don’t eat!

In a recent study of Denver households, the NRDC found that the average amount of food wasted, per person, in households included in this study was about 4.2 pounds of food per week. Of that, more than 76% of this wasted food could have been eaten (for example – a banana peel is considered an inedible food scrap in this study, but a discarded piece of banana is considered edible). If this situation sounds alarming, it certainly is. However, there is hope, and there are lots of great tools to help change things, especially in our homes. 

Here are a few quick tips and resources from to help prevent food from going to waste in the first place:

When we waste food, we’re essentially wasting everything that was used to produce it-- including water, energy, labor, fuel, time, and of course, money.  Even though the Denver Composts program can accept food scraps and food waste for composting, it’s always better to prevent food from going to waste in the first place.

Lend a Hand and Adopt-a-Spot in Denver


Denver’s Adopt-a-Spot program is a great resource for residents that are motivated to help keep Denver a clean and safe place to live and play.

The program is free, and perfect for groups of all sizes and participants of all ages. Groups ranging from organized civic groups, to families, to schools are encouraged to Adopt-a-Spot in Denver and commit to maintaining this spot for a year (or more!).



Adopting a spot is not only impactful, but also rewarding. Here’s what the commitment entails:

  • Maintaining a stretch of road, alley or open area (public right-of-way) for one year.
  • Providing the person-power to pick up litter, remove illegal signs and report graffiti vandalism.
  • Notifying the Keep Denver Beautiful program staff of planned cleanup dates so that supplies can be provided, and trash removal can be scheduled.

Denver’s Keep Denver Beautiful program staff is here to help you with your commitment and can provide organizational help, safety and procedure training, supplies such as bags, safety vests, work gloves and tools (as needed), and trash pick-up after each cleanup. Your group will also receive a customized sign to advertise your commitment.

 If your school group, business, church, family, or another group wants to commit to adopting a spot, more information can be found online at  or by calling 311. For more information about all other services and programs offered by Denver Solid Waste Management, visit  or call 311 (720-913-1311).

Help Denver Meet its 2020 Recycling and Composting Goal!

In 2018, Denver households generated about 230,000 tons of waste, but only recycled and composted about 57,000 tons of this material. To achieve our 2020 goal of reaching a 34% recycling and composting rate, Denver residents will need to recycle and compost 22,000 more tons per year, which is approximately one more pound, per household, per day! In other words, we can do this!

Getting one more pound of recyclable and compostable materials out of the trash cart and into a recycle or compost cart is easy. Here are some quick actions that you can take today to make this happen:   

Compost more! Nearly 50% of the material in Denver’s trash can be composted. 

  • Sign up for Denver composts. The Denver Composts program is perfect for keeping food waste, yard debris and non-recyclable paper out of your trash (and out of the landfill). Compost collection service is provided by the City for $9.75 per month (billed quarterly), and the green cart is emptied weekly.
  • Learn more about all your composting options, including backyard composting and vermicomposting, at

Recycle more! Nearly 25% of the material in Denver’s trash can be recycled.

  • Do your part to reduce the number of recyclables that mistakenly end up in the trash. Brush up on the list of materials accepted in the Denver Recycles’ program at, and practice your sorting skills with the Denver Recycles Waste Sorting Game.  
  • Increase your recycling capacity by upsizing to a larger purple recycle cart. Many residents have 65-gallon purple carts that can be exchanged for larger, 95-gallon purple carts. If a large purple cart isn’t enough, your home can also request a second recycle cart. 


Reduce the size of your black trash cart.

  • Your black trash cart comes in three sizes (35-, 65- and 95-gallon). Downsizing to a smaller cart will save space around your home and encourage stronger recycling and composting habits.

Keep These Items OUT of Your Purple Cart!

Closing the loop and using recycled material rather than virgin materials to make new products is proven to reduce our impact on the environment by reducing resource use, reducing energy and water use, and by reducing greenhouse gas emissions. Denver residents that recycle using their purple carts and purchase materials made with recycled-content are directly involved in closing the loop, but it’s important to note that Denver residents must also take responsibility for keeping this process moving smoothly by only placing acceptable materials in their purple carts.

Recyclables placed in Denver’s purple recycle carts are collected by Denver Solid Waste Management trucks and transported to Denver’s material recovery facility (or “MRF” for short) for processing. At the MRF, the recyclable materials are sorted into like items, and then compacted into large cubes, called bales, that are loaded onto trucks and trains for transportation to manufacturing facilities where new products are made from recycled materials. 

Sorting the recyclables from your purple carts isn’t an easy job. Denver’s MRF uses a combination of heavy equipment, conveyor belts, screens, robots, magnets, and people to make this possible.  The sorting equipment at the MRF is designed to handle a large volume of acceptable materials.  However, even small quantities of materials not accepted in Denver’s recycling program can damage the equipment at the MRF and slow the process down.  While all contaminants are problematic and costly to remove, certain items rise to the top of the “keep these out of your purple cart” list.

image of items to keep out of recycling cart

The top four items to keep out of your purple cart include:

  • Bagged Recyclables. Only loose recyclables can be sorted at the MRF. Placing recyclables inside plastic bags could result in the entire bag being thrown out. The best option is to keep plastic bags out of purple carts entirely.
  • Plastic Bags or Film. Just as bagged recyclables are a problem for a MRF, the MRF also cannot handle loose plastic bags or other plastic films. For bags that can’t be avoided in the first place, consider taking these bags and films back to the grocery store instead. The group, Plastic Film Recycling, maintains a list of plastic film drop-off centers across the country:
  • Scrap Metal. The only metal accepted in Denver’s purple carts are steel cans, and aluminum cans, trays, pie tins and foil. All other metal is considered scrap metal and should be kept out of purple carts.  A list of local scrap metal recyclers is included in the Denver Recycles’ online Recycling Directory.
  • Tanglers. Cords, hoses and chains are never accepted in purple carts and can cause damage to sorting equipment that is both costly and time-consuming to repair. Remember to keep these out of your purple cart!

Denver is Building Good Recycling Habits at Home and at School!

Denver Public Schools Recycles

It’s back-to-school season, and Denver’s schools are coming back to life with the start of a new school year. While many things can change from year to year at individual schools, one thing remains the same across the board — Denver Public Schools is committed to recycling!  For nearly a decade, Denver Public Schools and Denver Recycles have partnered to provide trash, recycling and compost collection at 160+ Denver schools across the City. Denver Solid Waste Management collection crews collect materials from school facilities, and both District and City staff work together to educate students and keep programs running smoothly.

Individual school recycling and composting programs wouldn’t be possible without the hard work and dedication of teachers, students, administrators, facilty managers, kitchen staff, parents, and other individuals involved with school operations. Before kicking off another great year of parthership, it’s worth celebrating the accomplishments from the 2017-2018 school year.

During the 2017-2018 school year, Denver Public Schools:

  • Recycled more than 3,000,000 pounds of material across the entire school district.
  • Composted more than 566,000 pounds of discarded food waste from 30 school cafeterias. 
  • Added 3 schools to the cafeteria composting program, bringing the total number of schools with cafeteria composting programs to 31.
  • Maintained and supported more than 160 school recycling programs.

In all, DPS kept 19% of its waste out of the landfill last school year. This school year, Denver Recycles looks forward to helping the DPS community in engaging an even greater number of students and staff in our recycling and composting programs.

For classroom resources, additional information about the DPS / Denver Recycles partnership, and for all other services offered by Denver Solid Waste Management, visit or call 311 (720-913-1311).

Composting is One Solution to our Food Waste Problem, But It’s Not a Silver Bullet

EPA food recovery pyramid informationThere’s no denying that food is a huge part of our daily lives. Food is woven into our everyday routines (multiple times per day),it is part of our celebrations, our traditions, and ultimately, our cultural identity. Despite the important role that food plays in all of our lives, Americans are guilty of wasting a lot of the food that we grow, process, distribute, and purchase. The Natural Resources Defense Council estimates that more than 40% of food is wasted, from farm to fork. And, when we waste food, we’re essentially wasting everything that was used to produce it-- including water, energy, time, and of course, money. The average American family of four spends roughly $1,500 on food that they don’t eat!

Since wasting food wastes everything that went into making it, it should come as no surprise that cities like Denver are looking to decrease the amount of food that ends up in trash carts. According to a recent waste audit by Denver Solid Waste Management, food is actually the largest single item found in Denver’s trash carts. Since tossing edible food in the trash is wasteful and also generates greenhouse gases as it decomposes in our landfill, landfilling this material should be done only as a last resort. Composting is certainly preferred over landfilling, but reducing the amount of food that goes to waste in the first place is the best possible solution. The EPA’s Food Recovery Hierarchy is a helpful tool in prioritizing methods of food waste prevention

Here are three quick tips and resources from Save the Food to help prevent food waste in the first place:

The Natural Resource Defense Council’s Save the Food website,, is full of great resources to help prevent food waste. For additional information about composting and other services offered by Denver Solid Waste Management, visit, or call 311 (720-913-1311).

School’s Out for Summer! Summer Safety Reminders from Denver Solid Waste Management

photo of back warning sign on trash truckSummer is officially here! School is out of session, the days are longer, and Denverites of all ages are taking advantage of the warm weather. The streets and alleys are full of walkers, bikers, kids, and of course, their dogs. On top of the increase in pedestrian traffic, the summer months are the busiest months for Denver Solid Waste Management’s trash, recycling and compost collection crews.

To keep up with summer activities and the waste associated with them, there are more than 100 trucks collecting material in Denver’s neighborhoods on any given weekday. While Denver’s talented collection crews are always on the lookout for cars, people and pets, it’s just as important for Denver residents to be aware and alert this summer while sharing the streets and alleys with collection trucks.

Below are a few safety reminders for Denver residents:  

  • Be aware — Denver’s trash, recycle and compost trucks are large, heavy, and challenging to operate. Each truck weighs between 30 and 50 tons, so it’s important to steer clear and give them room to maneuver and stay back!
  • Be patient — emptying carts takes time. Denver’s specialized collection trucks are designed to be efficient at collecting carts, but they might not move as quickly down the street as the rest of traffic. If you find yourself behind a collection vehicle, be patient and make sure they see you. Aggressively passing collection vehicles is unsafe for everyone.
  • Listen for beeping. Loud beeping is the sign of a truck backing up (which is sometimes required to service some of the tight streets and alleys around town). Always stay clear of trucks especially when they’re backing up.
  • Be smart, and help keep kids safe. Observing trucks and waving at drivers is great, but this should always be done from a distance. Help teach kids to use caution around all vehicles (large and small), whether they’re moving or not.

Keeping Denver safe is a community effort, and Solid Waste Management needs your help keeping residents and collection crews out of harm’s way this summer (and year-round!). For additional information about services offered by Denver Solid Waste Management, visit or call 311 (720-913-1311).

Tossing Your Old Textiles is So Last Year – Recycle Them Instead!

photo of pile of used clothesAccording to national estimates, Americans generate nearly 16 million tons of textile waste each year (think clothes, sheets, towels, etc.), yet only 15% of that waste gets recycled. This equates to more than 70 pounds of textile waste, per person, per year!

Despite the many textile recycling options available for Denver residents, approximately 3% of the trash collected by Denver Solid Waste Management is textile waste (that’s about 10 million pounds per year!).

Help us change this trend by following the tips below.  


  • Rent! Don’t Buy. Believe it or not, the sharing economy extends to clothing too. Whether it’s a wedding, another formal occasion, or day-to-day clothes, local retailers and online platforms offer opportunities to rent suits, gowns, work clothes and other accessories.
  • Host or Attend a Clothing Swap. Just because you’re tired of a pair of pants or shirt you’ve had in your closet for years, it might be just what someone else is looking for. Use a clothing swap as an excuse to get together with friends and freshen up your wardrobe.


  • Thrift Stores. Whether it’s for clothing or for repurposing, your unwanted clothing is still in high demand. Some Denver area thrift stores take clothing even if it’s stained, ripped or otherwise unfit for wear. Be sure to always check the clothing donation guidelines for your local thrift store prior to dropping anything off.
  • Textile Recyclers. Look for drop-boxes located all over the Denver metro area. Clothes donated to these outlets are shipped abroad to be used as secondhand clothing, or they’re turned into cleaning rags or carpet padding here in the U.S. Check the Denver Recycles’ Recycling Directory for drop-off options near you.


  • Buy Second-Hand or Vintage. From casual consignment stores, to costume shops, to bridal boutiques, Denver area businesses have you covered with second-hand options.
  • Buy Recycled-Content. The recycling industry is sustained through the demand for products made from recycled-content materials. Check labels for recycled-content the next time you buy clothing, shoes, carpeting, or cleaning rags. These items are commonly made with recycled or repurposed textiles, or other recycled materials.
  • Support Products Backed by “Extended Producer Responsibility.” Look for retailer-sponsored repair and/or take-back programs for textiles. These programs help to encourage higher-quality materials, repairable designs, and/or materials that can be recycled.

Denver Recycles does not accept textiles in its purple cart recycling program, but a full list of local textile recycling options can be found online using the Denver Recycles’ Recycling Directory. For additional information about all other recycling options in Denver, visit, or call 311 (720-913-1311).

Give Yourself a Break This Summer by Grasscycling

Save yourself time and energy this growing season by grasscycling, which is the process of leaving your grass clippings on your lawn after mowing. Grasscycling makes mowing quicker and easier, and is the natural way to return nutrients to your lawn.

photo of lawn mower mowing green grassMore than a quarter of Denver’s household trash is composed of yard debris, and grass clippings account for a large portion of this material from April to September. By grasscycling, you can help stop this material from ending up in landfills and have a real impact on reducing greenhouse gas emissions. If you’re not already a grasscycling pro, give it a try this summer! 


1.  USE ANY MOWER. Remove the mower collection bag to allow clippings to fall back on the lawn. If your mower does not have a safety flap covering the opening over which the bag fits, then you may need to purchase a retrofit kit from your local hardware store.

2.  MOW WHEN IT’S DRY. Wet grass clippings clump together and do not feed your lawn as well as dry grass clippings.

3. FOLLOW THE “1/3 RULE.” To foster healthy grass, do not cut more than 1/3 of the length of the grass at any time, and make sure that clippings are no more than one-inch long. Lawns are healthiest when they are mowed to a height of 2 ½ to 3 inches.

If you hire a landscaper to mow, be sure to ask them to adopt grasscycling methods when mowing your lawn.

A Denverite’s Guide to Composting Methods: Find What’s Right for Your Home!

graphic of composting optionsEven though Denverites are recycling and composting more and more each year, an alarming amount of “good stuff” (otherwise known as recyclable and compostable material) is still ending up in Denver’s landfill. As shocking as it may sound, more than half of the materials Denver residents currently send to the landfill are organic (once living) materials and could have been composted. Denver can certainly do better, and doing so starts with decisions made in your home!

Denver Recycles offers a number of tools to help Denver residents reduce the amount of material ending up in Denver’s trash. Not every approach is feasible or appropriate for every home, but there is something that can work for everyone. To maximize the benefits of keeping this “good stuff” out of the landfill, Denver Recycles encourages residents to choose one, two, or all of the compost options outlined below.

The options below can and should be combined for best results at your home and for maximum benefit to the environment:

  • Denver Composts! Enroll in Denver’s fee-based compost collection program and receive a green kitchen compost pail, a green compost cart, and weekly collection service. This program accepts food, non-recyclable paper products, and yard debris. Denver Composts! is now offered in all Denver neighborhoods!
  • Backyard Composting. Backyard composting is a fun and rewarding way to reduce waste and create a useful compost product in your own backyard. To learn more about the backyard composting process, build skills, or just boost your confidence in your ability to turn food scraps and garden debris into compost at home, consider signing up for one of Denver’s FREE Learn to Backyard Compost (offered May through October at Denver’s Backyard Compost Demonstration Site). Or, just make a trip to Denver’s Backyard Compost Demonstration Site to find inspiration, and to check out the various methods and containers that can be used for backyard composting.
  • Worm Composting. Worm composting, also known as vermicomposting, is an indoor composting option available to everyone, and an ideal option for apartment dwellers and anyone else with limited space. A healthy worm box full of red-wiggler worms will happily consume their weight in veggie scraps and leaves each week, producing a high-quality soil amendment that can be used to feed gardens and houseplants alike.
  • Cherry Creek Recycling Drop-off (CCRD). The Cherry Creek Recycling Drop-off accepts single-stream recyclables and all material accepted in the Denver Composts! program. The site is open Tuesday through Friday from 10 a.m. to 5 p.m., and Saturdays from 9 a.m. to 3 p.m., and is especially helpful for the occasional surplus of compostable (or recyclable) materials.

No matter how it’s done, composting is an approachable and meaningful action that helps Denver residents decrease their impact on the climate, conserve resources, reduce pollution, and improve soil health. And, composting is essential for Denver to be able to meet its 2020 Sustainability Goal of keeping 34% of its waste out of the landfill.  For these reasons, Denver Recycles encourages residents to choose one or all the above options for managing organic waste at home! 

Don’t delay — start composting even more, today! For more information about backyard compost, Denver Composts!, and other Denver Recycles programs, visit or call 311 (720-913-1311).
