Zoos and aquariums face tremendous opportunities (and expectations) for creating eco-friendly waste management programs. The public expects these institutions to offer comprehensive recycling and compost programs to demonstrate their commitment to the Earth. Thankfully, America's zoos and aquariums are up to the challenge. Let's take a look at some innovative institutions to see what they're doing and how they're doing it.


Columbus Zoo and Aquarium: Leaders in Composting


With Jack Hanna on the board of directors, you'd expect the Columbus Zoo and Aquarium to have a top-notch collection of animals. However, the Ohio zoo takes its commitment to the Earth a step farther. It has an innovative composting program that sends 864 tons of material to a local commercial composter. That's 1,728,000 pounds of food scraps, animal manure, and bedding!


Zoos have the unique opportunity to be such prolific composters due to the large amount of animal manure produced. For instance, at the Columbus Zoo and Aquarium, the animals produce about two tons per day. By partnering with a nearby facility, the zoo is able to solve a waste management problem while creating nutrient-rich soil and local jobs in the process. 


By collecting food scraps in their kitchens, the zoo adds even more useful organic material to their haul of compost. Zoo maintenance workers can also divert soiled animal bedding from the landfill and send it to the composting facility. Maintenance managers should just remember to provide assistive lifting devices when asking workers to handle awkward, heavy loads.


Philadelphia Zoo: 2017 Green Award Winners


The Philadelphia Zoo has been around for more than 150 years, but it’s still coming up with innovative solutions to worldwide problems. Its current focus is on sustainability, and it’s created an ambitious set of goals to continually drive down energy expenditures and water use.


Two of the zoo's major sustainability goals involve water conservation, and it’s created innovative approaches to achieve them. For instance, to reduce water consumption, it’s installed waterless urinals, and it collects rainwater to flush toilets. These are great examples of changes that save water without negatively impacting the zoo experience.


Over a five-year period from 2009 to 2014, the zoo decreased water use by 64 percent. It’s also removed large swaths of pavement and replaced it with rain gardens and infiltration basins to capture rainwater. This reduces local flooding and gives the zoo extra water to use for landscaping and other applications that use non-potable water. In 2017, the Association of Zoos and Aquariums honored the Philadelphia Zoo's sustainability program with their prestigious Green Award.


Recycling at Zoos and Aquariums


Recycling programs in zoos have never been more robust. Almost all zoos collect plastic, glass, and aluminum, but it's also becoming commonplace for them to accept cell phones and more obscure items. The Topeka Zoo even accepts old holiday lights, which are dismantled and recycled for parts.


This focus on recycling is about more than just keeping junk out of landfills; it also reduces the need for mining and deforestation. More specifically, cell phones require a mineral called coltan that comes from Congo. By harvesting and reusing coltan from old cell phones, there is less need to mine it from the habitat of the lowland gorilla, which helps conserve the species.


As stewards of wild animals, zoos are creating a multitude of programs to help the earth. Whether it's through the alchemy of composting, simple solutions to reduce water use, or reusing parts from old items, zoos are meeting and overcoming their unique waste management challenges.


Solus Group offers a wide variety of quality material handling products with solutions focusing on warehouse storage, shelving, battery handling, industrial safety, dock accessories, drum handling, packaging, industrial and office furniture, and janitorial maintenance.

Apparel Impact

By Sophie Leone • February 12, 2026
Established in 2015, Apparel Impact has been working within their community to reduce textile waste, fight clothing insecurity, create jobs, and ensure those in the community in need of clothing never go without. This family and veteran owned company is built on the foundation of disruption for good. The Apparel Impact team has been working to make real changes in an industry that has remained the same for many decades. They continuously push for transparency, accountability, and working solutions in the field. Today Apparel Impact works with over 1,800 partners and locations, including schools, towns, nonprofits, national brands, and small businesses across six states. Apparel Impact is also working to bring textile sorting and grading capacity back to the Northeast, while launching upcycling brands aimed at scaling textile reuse across the region. For Apparel Impact, it is all about “changing the way people think about clothing, proving a for-profit company can still put people and communities first, and making sure what we collect helps someone’s life, not a landfill.” Their impact and reach continue to grow every year. “Textile recovery only works at scale. It takes leadership, accountability, and real collaboration across states and sectors. We joined NERC because we believe in building infrastructure that actually changes outcomes, not just talking about it. We’re proud to stand with the NERC and others in the Northeast who are ready to move the industry forward.” NERC is excited to welcome Apparel Impact to our growing group of textile focused members. We look forward to amplifying their voice and helping to expand textile recovery in any way we can. For more information on Apparel Impact visit.

Planet Aid

By Sophie Leone • January 20, 2026
Planet Aid is a nonprofit established in 1997 to divert clothes and shoes from the U.S. waste stream and fundraise for community development programs around the world. With thousands of donation bins and centers across the Northeast, Mid-Atlantic and Midwest, Planet Aid’s mission is to inspire positive change by making it easy for donors, partners and communities to take small steps that add up to a big impact. Over three decades, Planet Aid has collected more than two billion pounds of clothes and shoes for reuse. These donations have helped Planet Aid raise more than $100 million to fund community-led projects in the U.S., Africa, Asia, and Latin America. With headquarters just outside Baltimore, MD, Planet Aid serves thousands of communities in 14 states, including New York, New Jersey, Maine, Massachusetts, Connecticut and more. For those without a yellow collection bin or white donation center nearby, they've developed a donation through mail option. By partnering with Give Back Box, you can pack up and mail your donation items directly to their thrift store. This inclusive approach allows them to reach more communities, diverting even more waste that may have gone to a landfill or incinerator. “Planet Aid is excited to join NERC, an organization that shares our goals of minimizing waste, conserving natural resources, and advancing a sustainable economy,” said Uli Stosch, Planet Aid’s Chief Officer of Strategic Development. “We looking forward to collaborating with NERC’s members to help U.S. communities in the Northeast minimize textile waste while maximizing reuse to limit the negative impacts of fast fashion.” NERC is excited to welcome Planet Aid into our growing group of nonprofit members. We look forward to helping share the excellent work they are doing in the NE and around the world. For more information on Planet Aid visit.
