When organic materials break down, they create a nutrient rich soil amendment that helps restore farmland and promote sustainable agriculture. It’s important to protect this cycle as the soil that is produced is often used to grow the food we eat here at CU.

As a student at �鶹��Ѱ��Boulder you have the unique opportunity to directly impact the local soil cycle. Your efforts help keep our compost stream clean so local farmers and gardeners can provide us with the best food.

What you can compost

As of April 1, 2023, A1 Organics no longer accepts previously compostable materials such as napkins, paper towels or serviceware labeled as “compostable.” Food scraps and yard waste are the only items currently accepted. Since these changes, �鶹��Ѱ��has continued to be able to compost the majority of what we previously composted. While public facing compost bins had to be removed, staff on campus are working to expand compost access on campus.

Composting efforts on campus

One effort to reintroduce access to composting is being led by �鶹��Ѱ��Facilities Management. They have a pilot program to place small food scrap buckets in kitchenettes and discreet areas around campus. For example, in the Sustainability, Energy and Environment Community (SEEC) building, there are buckets in several of the kitchens used by students and staff. Each week, Facilities Management staff empties the small buckets into a larger compost receptacle, which is then taken to the on-campus Grounds and Recycling Operations Center (GROC) to be sorted and combined with other food waste for composting.

If you live or work on campus and would like to participate in this food scrap composting pilot, please fill out this form today! We have a limited number of food waste collection bins available in various locations across campus for folks who sign up to participate in the pilot!

Another effort to divert edible food waste from disposal on campus is being led by �鶹��Ѱ��Dining Services. This involves collecting food scraps produced during food prep and transporting it to a local regenerative farm, Golden Hoof. These scraps feed livestock, like chickens and pigs. This not only diverts food waste from the landfill, but it also reduces the need to grow and produce food for the animals, resulting in a win-win for the environment. The Golden Hoof scrap program is currently taking place at the UMC and C4C, with hopes to expand it to Will Vill in the future. Dining Services also composts hundreds of tons of food waste per year from food prep in kitchens as well as from food scraps left over by students when plates are washed in the dish rooms.

Another program to increase composting is handled by the Environmental Center’s Zero Waste Team. During large events like football games, basketball games and concerts, a team of students sort all waste following the event. Students set up tables, wear gloves and hand sort through hundreds of bags of compost and recycling. Dumpsters dedicated to landfill, recycling and compostable items capture the separated materials, which are hauled to each respective facility for processing. During the 2024 football season, the Environmental Center partnered with �鶹��Ѱ��Athletics, Levy Restaurants, Facilities Management, and A1 Organics to pilot a high-quality compost load containing hand-sorted food waste and CMA certified compostable service wares. This process ensures that only the pre-approved materials were purchased for food service and produced a very desirable mixture to be processed at the local compost facility. CMA certified compostable products are tested and verified to break down properly in industrial composting facilities. Thanks to the dedication of this team effort, 17,572 pounds of organic materials were successfully composted this season. Ultimately, with lessons learned from 2023, we need to keep in mind the goal is to transition away from single use systems.

The Zero Waste team is looking at the changes in accepted compost as an exciting opportunity to rethink the way our food disposal and purchasing systems work. CU’s newly adopted Climate Action Plan calls for reducing waste, phasing out single-use plastics, and switching to more reusables for some operations. Instead of continuing to have single-use, compostable products like to-go boxes and cups, �鶹��Ѱ��could implement a reusable system. This might change to all reusables for dining, whether you are eating in-house or taking it to-go. The to-go item would be checked out during food purchase and then returned by the user to be washed, sanitized, and used again. This could help cut down on the “take, make, waste” system of single-use items and create a more sustainable model for our campus.

Students can help bolster these efforts by advocating for programs, getting involved with the Environmental Center or sharing ideas with student government.

Composting in the Community

For campus community members who live off campus or frequent off-campus locations, Boulder County published a composting changes FAQ explaining how A1 Organics’ changes will impact trash collection in the surrounding Boulder community. For campus community members who live outside of Boulder County, Eco-Cycle published composting guidelines for the Front Range region.

Despite recent changes in regional composting rules, �鶹��Ѱ��Boulder continues to lead innovative composting and food waste diversion efforts across campus from pilot programs and partnerships with local farms to game day waste sorting and a push for reusables.

A Day in the Life of a Sustainable College Student at �鶹��Ѱ��Boulder

A Day in the Life of a Sustainable College Student at �鶹��Ѱ��Boulder Anonymous (not verified) Sun, 10/12/2025 - 18:26

The key to being a sustainable college student is finding balance through the accessible actions that fit into my day and create positive impact. Over time, I’ve learned that sustainability isn’t all or nothing. I think of my efforts as a mix of learning from �鶹��Ѱ��Boulder’s sustainability community, building daily habits that add up, and making meaningful choices that align with my values, all with a focus on progress over perfection.

Learning from �鶹��Ѱ��Boulder’s sustainability community

This mindset sank in through Environmental Center events. At America Recycles Day, I received Tupperware and metal straws that quickly replaced single-use items. What felt like a small change became a reminder that reducing waste often starts simply. Volunteering at Ralphie’s Green Stampede made this lesson tangible by seeing the volume of waste produced at a single game. It emphasized the importance of our mindset about what we consume.

Routines add up

In daily life, these ideas show up in small habits. I start my day by filling my reusable water bottle, saving over 150 plastic bottles a year. I take the Buff Bus instead of driving, which helps get me further on campus, avoids the stress of parking, and saves money. These small choices help both the planet and my budget. On campus, sustainability shows up everywhere. At Folsom Field, Ralphie’s Green Stampede sorts trash after games, proving sustainability can be woven into traditions people already love. Even as Boulder’s composting rules change, �鶹��Ѱ��and Ralphie’s Green Stampede community keep adapting.

Sustainable choices make memories

Off campus, sustainability blends into my social life. My friends and I use BCycles when going out, and some of the best memories come from those rides; even biking uphill on a half-dead BCycle feels worth it. Choosing the sustainable option can add to the experience, not take away from it.

Progress over perfection

Of course, I’m not perfect. There are days I forget my reusable water bottle or grab takeout in plastic containers. �鶹��Ѱ��Boulder’s sustainability culture has shown me that it’s not about perfection, it’s about weaving sustainable choices into daily life. Sustainability here isn’t a separate “to-do list” for students. It’s built into the free bus rides, B-Cycles, Ralphies Green Stampede, and everyday conversations. In those ordinary, everyday life choices, sustainability becomes less about guilt and more about being a part of something bigger. Join the community today by signing the Sustainable Buffs Pledge.

Students and community partners keep thousands of items out of landfill Jenna Morrow Fri, 10/10/2025 - 13:25

Each move-out season brings a surge of unwanted items as students transition out of Boulder’s rental housing. To reduce waste and support reuse, �鶹��Ѱ��Boulder’s Off-Campus Life (OCL) and the Environmental Center partnered with the City of Boulder, Boulder Area Rental Housing Association (BARHA), and local Zero Waste organizations for a coordinated effort to collect reusable items and divert materials from the landfill.

In 2025, five drop-off stations were set up on the Hill during both spring (May 11–14) and summer (July 31–August 3) move-out periods. Stations were located at 11th & Penn, 13th & Euclid, 15th & Euclid, 10th & College, and 12th & Aurora—with Aurora and 12th proving most popular in the spring, collecting 339 items, and 15th and Euclid taking the lead in the summer with 350 items.

Across both events, students and community partners made a measurable impact.

Spring 2025: 11.9 tons were sent to the landfill, while 5.145 tons were diverted, achieving a 30% diversion rate.

Summer 2025: 22.92 tons went to the landfill and 6.5 tons were diverted, for a 22% diversion rate.

Together, these efforts kept over 11 tons of materials out of the landfill in just two move-out periods. Volunteers and staff supported 43 pickups, sorted donations, and ensured items were properly managed at each site.

Looking ahead, OCL, the Environmental Center, and community partners are exploring ways to expand collection efforts into additional neighborhoods while keeping the program financially and environmentally sustainable.

Want to help?
Be part of the move-out solution next year! Whether volunteering with the Environmental Center, donating before trashing items, or shopping reused at local partners like Resource Central and CU’s Surplus Store, every action helps keep Boulder cleaner and more sustainable.

�鶹��Ѱ��Boulder and City of Boulder Expand Student Move-Out Waste Diversion Efforts Jenna Morrow Tue, 06/24/2025 - 13:04

From May 11-14, a unique community partnership brought together the City of Boulder, �鶹��Ѱ��Boulder, Boulder Area Rental Housing Association (BARHA) and Zero Waste organizations to support students and reduce landfill waste during move-out. Recognizing the increased waste during this time of year, �鶹��Ѱ��Boulder’s Off-Campus Life and Environmental Center partnered to set up five stations along the Hill for students to take belongings they no longer need. Goodwill, USAgain, Eco-Cycle, Resource Central, Home Ahead and the �鶹��Ѱ��Distribution Center took many usable items from the stations to resell or recycle, helping to close “the loop” and provide convenient ways for students to get rid of items.

With the success of the project and strong partnerships, we are doing it again! Many leases end in late July and early August, so we are hosting a second round of this project during this time from July 31–August 3.

Whether you are passionate about contributing to the city’s circular economy goals, want to give back to the community or are curious about what students leave behind, we need you!

Sign up for Move-Out shifts July 31st - August 3rd
Can’t volunteer but want to help out? Please support our zero waste partners by shopping reused! Visit CU’s Surplus Store on Walnut and 33rd, Resource Central or any Goodwill location to support our partners.

Help reduce move-out waste and support Boulder’s circular economy — volunteer or shop reused during �鶹��Ѱ��Boulder’s upcoming student move-out event July 31–August 3.

Celebrating Marianne Martin’s Lasting Impact on �鶹��Ѱ��Boulder Jenna Morrow Tue, 05/06/2025 - 11:28

After more than 25 years of extraordinary service to �鶹��Ѱ��Boulder, Marianne Martin is retiring at the end of this month. As Associate Director of the Environmental Center, Marianne has been a driving force behind many of the university’s most innovative and influential sustainability efforts. Her legacy spans decades, programs, and people—and reflects the kind of leadership the Environmental Center has fostered over its 55-year history.

Marianne began her journey at �鶹��Ѱ��Boulder as a student where she was active with Wilderness Study Group. After helping start a non-profit after graduating, she joined the Environmental Center staff in 1998 and has dedicated her professional career to building a more just, sustainable campus. Under her leadership, the Center’s staff and budget quadrupled. She played a key role in developing institutional sustainability plans and initiatives that set �鶹��Ѱ��Boulder apart nationally such as; Sustainable �鶹��Ѱ��Grants, EcoReps in the residence halls, One Million Acts of Green, green purchasing programs, sustainable food, and campus pollinator gardens, and the Green Office certification program. She also launched programs that engage students directly in sustainability careers and changemaking, including the Campus Sustainability Roundtable, Teach for Sustainability internship, and sustainability action teams. She’s been a collaborator on partnerships such as Ralphie’s Green Stampede, FLOWS, relocating the campus recycling center and the Williams Village greenhouse.

For over a decade, Marianne led the charge to bring the national Bioneers conference to �鶹��Ѱ��Boulder as well as the Annual Campus Sustainability Summits. These events connected students and community with a powerful mix of environmental justice, cutting edge scientific solutions, and sustainable leaders from across sectors. She built community coalitions, coordinated logistics, and inspired innovation across campus, year after year. Her work was recognized in 2014 with the “Women Who Make a Difference” award, and most recently, she received the �鶹��Ѱ��Boulder Campus Sustainability Legacy Achievement Award for her enduring impact.

Beyond programs and plans, Marianne’s greatest legacy may be her mentorship. Hundreds of students and staff have grown under her guidance to become sustainability leaders in their own communities. She’s known for cultivating a culture of collaboration, care, and purpose that will continue to shape the Environmental Center for years to come.

As Marianne retires, we extend our deepest gratitude. Thank you, Marianne, for your unwavering commitment, your vision, and your heart. You’ve made �鶹��Ѱ��Boulder a better place and your legacy will continue to inspire change for generations.

Give and Go: Move-Out 2025 Jenna Morrow Wed, 04/16/2025 - 15:17

Spring has arrived, and that means �鶹��Ѱ��Boulder students are moving out! With nearly 8,300 first-year students living on campus, the �鶹��Ѱ��Environmental Center is preparing for the annual Give and Go Drive. Drop off stations will be set up in 26 campus halls in common rooms starting April 18 until May 8 to collect items in good condition for donation.

The donated items we will be accepting are clothing, furniture, non-perishable food, personal care products, and school supplies. These items will then be collected and processed by our partners—Resource Central, �鶹��Ѱ��Distribution Center, Basic Needs Center, Buff Pantry, and the newly opened �鶹��Ѱ��Surplus store—to be distributed at little or no cost to those in need, most items will go back to our local community. Last year, an incredible 21 tons of items were donated, as well as diverting 14% of usable goods that could have ended up in a landfill.

By donating, you’re helping to build a circular economy, reducing waste, and strengthening our Buff culture of sustainability. Want to do even more? Volunteer! We’re looking for dedicated individuals to assist with collection and distribution efforts. It is a great way to give back to your city and by getting involved!

Join us in making this move-out season more sustainable and impactful!

Additionally, if you or anyone you may know is interested in participating in the cycle of re-use, Resource Central will be hosting a �鶹��Ѱ��Yard sale for items collected from Move Out on May 17th, starting at 9am. At this sale you can shop for gently used lamps, decorations, storage bins, and fans which will cost significantly less than buying new products while enjoying local music.

Help make move-out season more sustainable by donating gently used items through the Give and Go Drive or volunteering to support collection efforts—plus, don’t miss the �鶹��Ѱ��Yard Sale on May 17!

�鶹��Ѱ��Boulder's Zero Waste Initiative: A Pledge for Climate Action through Regenerative Agriculture Anonymous (not verified) Mon, 01/22/2024 - 15:48

With confirmations that 2023 was the hottest year on record, your support is needed to take a proactive approach to addressing climate change through regenerative agriculture and building healthy soils. The �鶹��Ѱ�� is making significant strides in sustainability with its Spring Zero Foodprint pilot, a commitment that extends beyond the campus borders and into the Colorado community. In collaboration with Zero Foodprint, �鶹��Ѱ��Boulder's effort to organize business owners and the �鶹��Ѱ��community is helping build healthy soils across Colorado, focusing on regenerative agriculture projects and climate action.

The Zero Foodprint Pledge:

One of the core elements of �鶹��Ѱ��Boulder's Spring Zero Foodprint pilot, is the pledge taken by third-party vendors to contribute 1% of sales towards supporting build the Restore Colorado grant. This often amounts to cents out of your total bill! This 1% addition is designed to mitigate the climate impacts of businesses and people, as well as showcase a steadfast dedication to climate action and the regenerative agriculture movement. Funds collected from the participating businesses are directed into a pool used to provide grants to local farmers and ranchers. This financial support not only aids in sustainable agricultural practices but also acts as crucial matching dollars to unlock additional funds from philanthropic donors, corporate sponsors, and government grants. To date, the collective action of the Zero Foodprint community associated with Colorado has resulted in the deployment of $323,336 to 30 farms. This financial support is expected to sequester over 42,000 tons of CO2 equivalent, which is the same as 13,000 tons of waste recycled instead of landfilled. This remarkable impact underscores the effectiveness of collaborative efforts in addressing climate change through regenerative agriculture.

Tim Schiel at the UMC Subway has been participating in the Zero Foodprint program since 2021 and is setting an example for other business owners on campus.

�鶹��Ѱ��Boulder encourages its business community to sign up for the Zero Foodprint Spring Pilot program. Participants in the program practice transparent financial transactions. When contributing to the cause, businesses explicitly name "Zero Foodprint" or “Restore Colorado” in their storefront and receipts. This ensures that anyone interested in learning more can easily find information about the Zero Foodprint program. Moreover, it’s important to note that these contributions are voluntary and not a tax- if you don’t want to contribute financially to Zero Foodprint, you can always opt-out!

By actively engaging the �鶹��Ѱ��community into the Zero Foodprint efforts and fostering transparency in financial transactions, we as the �鶹��Ѱ��Boulder community can make significant strides in achieving a sustainable and climate-friendly future. Through ongoing commitments and collaborative efforts, the �鶹��Ѱ��Boulder community members and businesses can set an example for how people can join together to make a positive impact on the environment.

Do you support this initiative? If so, please sign our letter of support here to let your favorite on-campus business know you want to see them participate in the Spring Zero Foodprint pilot!

Questions? Please reach out to ecenter@colorado.edu
