History

The International Day of Zero Waste was officially established by the United Nations General Assembly in December 2022 and its first celebration was in March 2023.

This day is now celebrated annually to promote public awareness across the globe about the need for more zero-waste initiatives as they work toward sustainable development.

Working to address the unsustainable practices in production and consumption, this event is supported by the United Nations along with many other environmental organizations, non-profits, sustainable businesses, and more.

Other events that are celebrated by Days of the Year along a similar theme as International Zero Waste Day are Zero Waste Week in March, Zero Emissions Day on September 21, and International E-Waste Day on October 14.

How to celebrate

Minimize Consumption

Every person, family, business, or school can use International Day of Zero Waste to take stock of the ways they consume without thinking. Ask some of these questions to get started: What opportunities might there be to cut down on fuel by running errands all at once or carpooling with a coworker? Is it possible to eliminate single-use products like throw-away paper plates or plastic forks? What about the simple idea of using cloth shopping bags instead of plastic ones? Or using beeswax cloths instead of plastic wrap?

Reuse and Repurpose

This is just the right time for consumers and businesses to get into the habit of thinking more carefully about the products they use. Get creative with ways to invest in sustainable habits like making use of refillable water bottles, coffee cups, and straws. Consider cooking more carefully with fresh produce (not packaged in plastic!), while repurposing vegetable scraps for broth and composting the rest. All it takes is a bit of clever thinking and looking at things differently before throwing them in the garbage can.

Advocate for Better Zero Waste Policies and Practices

Anyone can use their voices for International Day of Zero Waste by speaking up against wasteful practices and promoting sustainable businesses. Consumers can show support through the places they spend their money and citizens can show support for good eco-policies by the places they give their votes!

Shop Second Hand

For furniture, household items, clothing, and sporting equipment, consider shopping second-hand. This also works for cars, kids’ toys, electronics, and more! Not only does buying used or refurbished extend the life of an existing item and keep it out of the landfill, but it also means there is less waste coming from the factories that make new products. Plus, going vintage is just super cool these days!

FAQ

Is “zero waste” really achievable, or is it more of a guiding goal?

Experts describe zero waste as a long‑term systems goal rather than a literal promise that no waste will ever be created. The idea is to design products, services, and public policies so that waste is continually reduced and materials are kept in use for as long as possible through repair, reuse, recycling, and composting. Cities and companies that adopt zero‑waste strategies typically set measurable targets to significantly cut landfill and incineration, even if reaching absolute “zero” remains aspirational.

How is zero waste different from simply recycling more?

Zero waste focuses on preventing waste before it is created, while recycling deals with materials after they are already discarded. A zero‑waste approach prioritizes refusing unnecessary items, reducing consumption, reusing and repairing products, and redesigning packaging and supply chains so they generate less waste in the first place. Recycling and composting are still important, but they are seen as last steps in a broader strategy rather than the main solution on their own.

What role does zero waste play in tackling climate change?

Poorly managed waste contributes to climate change through methane emissions from landfills, energy use in producing new materials, and pollution from burning trash. Zero‑waste strategies reduce the need for extracting and manufacturing virgin materials, which cuts greenhouse gas emissions across the whole life cycle of products. International analyses of municipal solid waste show that shifting to waste prevention, reuse, recycling, and composting is one of the more cost‑effective ways for cities to lower emissions while improving public health.

How does waste affect people in low‑ and middle‑income countries differently?

In many low‑ and middle‑income countries, rapid urbanization and limited waste collection mean large amounts of trash are dumped or openly burned, often near informal settlements. This can contaminate water and soil and expose residents, including children and waste pickers, to smoke and hazardous materials. International assessments highlight that improving basic waste management and gradually adopting zero‑waste and circular economy measures can reduce these health risks while also creating safer, formal jobs in recycling and recovery.

Can businesses realistically move toward zero waste without raising prices too much?

Businesses that pursue zero‑waste practices often start by cutting inefficiencies, such as excess packaging, overproduction, and energy‑intensive materials, which can lower costs over time. Many firms adopt circular economy models, design products for easier repair or recycling, and participate in take‑back or refill systems. While there may be upfront investments in redesign and new logistics, case studies from regions implementing circular policies show that resource savings and new revenue streams from reused or recycled materials can offset costs rather than simply driving prices up.

What are some examples of city‑level zero‑waste policies that have worked well?

Several cities have adopted combinations of policies such as mandatory separation of recyclables and organics, bans on certain single‑use plastics, “pay‑as‑you‑throw” fees for residual trash, and investment in reuse and composting infrastructure. Well‑known programs include cities that set formal zero‑waste targets and then back them with ordinances requiring recycling and organics collection, along with public education. Evaluations of these programs show substantially higher diversion from landfills and incineration when regulations, infrastructure, and public engagement move forward together.

How does zero waste connect to food waste and food insecurity?

Food that is grown, processed, and transported but then thrown away wastes land, water, energy, and money, and it also generates greenhouse gases as it decomposes. At the same time, many communities face food insecurity. Zero‑waste thinking encourages preventing surplus food in the first place through better planning and storage, redirecting edible surplus to people in need through food recovery systems, and composting inedible scraps. This approach helps reduce environmental impacts while making better use of food within local and national systems.
