Accelerating a zero-waste future
Zero Waste
A zero-waste future requires a systemic approach. At Harvard, we aim to sustainably manage all waste streams—including plastics, electronics, recyclables, and organics, as well as construction, demolition, and hazardous waste—while prioritizing waste prevention and reduction.
Framework for Waste Stewardship
Zero Waste Future
In 2025, Harvard launched “Accelerating a Zero Waste Future: A Framework for Waste Stewardship,” a new plan to transition our campuses to zero waste. Developed by the Waste Stewardship Steering Committee in collaboration with University leaders, the framework prioritizes waste prevention, reduction, reuse, and responsible recovery, and aligns with Harvard’s Sustainability Action Plan.

Stop by the Smith Campus Center for an December Freecycle! Drop off reusable goods you no longer need, and browse a fantastic selection of items brought by others. Find some secondhand items to gift this year. Popular items include books, clothes, and working household goods.

Laura A. Stevens is a geophysicist whose research focuses on hydrological drivers of ice-sheet deformation, combining a range of observational techniques and theoretical approaches to understand ice-sheet dynamics in our warming climate. At Radcliffe, Stevens is interrogating a newly collected dataset to explore whether emerging, high-elevation lakes on top of the Greenland Ice Sheet could augment this ice sheet’s contribution to sea-level rise, alongside collaborating with Harvard’s polar oceanographers to reimagine directions for the joint field of fjord-ice-sheet dynamics.

Join Harvard Medical School for an event that will highlight the urgent challenges at the intersection of health and sustainability – including health inequity, climate change, biodiversity loss, antimicrobial resistance, infectious and non-communicable diseases, as well as weak health systems. These issues illustrate the inseparable links between human, animal, and ecosystem health, and underscore the need for a One Health approach to achieve effective solutions. With only five years left to reach the Sustainable Development Goals, the event will explore how the implementation of One Health can decisively strengthen global health and sustainability efforts. |

Embark on a birdwatching tour in the Arboretum’s landscape with docent and birder Donna Sullivan. This two-hour tour is suitable for adult beginners as well as more experienced birders.

Take a brisk walk this winter and stay healthy and connected to the Arboretum at a time when the landscape is pared down to its beautiful bones. Join docent Carol Kuo for a 90-minute walk that is similar to a guided tour, but with a slightly faster pace and fewer stops, to keep your feet warm and your blood pumping! Please dress appropriately for the weather including sturdy footwear. Each walk will cover a different part of the Arboretum, depending on weather and seasonal features.

When we think of electricity, we often picture wires, circuits and generators. But did you know that living things can also produce electricity? In fact, electricity powers many of the biological processes in living things, including us! Even more surprising is that bacteria can use electricity to “breathe rocks.” What does this mean exactly? Join Harvard scientist Federica Calabrese as she uncovers how some microbes evolved to live in oxygen-free environments and how we can harness “bioelectricity” to power our own electronic devices. 20-minute talk followed by 10-minute Q&A session. Recommended for ages 10 and up. Presented by the Harvard Museum of Natural History and Harvard Museums of Science & Culture. |

Embark on a birdwatching walk in the Arboretum’s landscape with birder and wildlife photographer Michael Bryant, AKA Nature Man Mike. This two-hour walk is suitable for beginners as well as more experienced birders. Binoculars will be available to borrow on a first-come-first-serve basis, but you are encouraged to bring your own!
–
Hardwood cuttings are one of the many techniques the Arboretum uses to propagate its plants: propagators take cuttings from the mature stems of woody plants, carefully trim and coat the ends in rooting hormone, then plant them in specially designed growing media. Join Arboretum Propagator Sarah Shank for a hands-on workshop to learn this specialized form of propagation: the class will begin with a presentation on the biology of hardwood cuttings, then head outside to collect our own cuttings from nearby woody plants, and finally return inside to prepare and root the cuttings in growing media. Participants will bring home a small tray of cuttings to grow into their own small trees and shrubs. |

Frederick Law Olmsted, considered the father of landscape architecture, designed some 500 public spaces in North America. The Arnold Arboretum is the only arboretum he designed, a National Historic Landmark, and a model for others around the world. Docent Bill Beizer, will identify the elements of the Arboretum that best reflect Olmsted’s philosophy and approach to landscape design. |

How is Harvard reducing waste?
Harvard is taking a systemic approach to waste prevention and reduction, aiming to ensure the materials that the University purchases and handles are used effectively and for as long as possible. Harvard is also strategically preventing waste throughout our value chain, while minimizing on-campus municipal solid waste (or trash) and sustainably managing other waste streams.
We are focused on piloting solutions on campus to reduce waste. The Waste Stewardship Committee is developing guidance and resources to help Schools and Business Units create their own zero-waste plans and goals.
Harvard will continue to measure and report data annually for Harvard’s major waste streams and aims to develop a strategic zero-waste plan by the end of 2024.
Harvard Recycling & Waste Management
The primary campus waste hauler office at Harvard manages all waste streams across Harvard’s Cambridge, Allston, and Longwood campuses. Explore their resources:
