Washington, DC’s Smart Bins Start a New Era for Urban Composting

Team Compost Connect, 03 August 2025
Washington, DC’s Smart Bins Start a New Era for Urban Composting

Washington, DC has taken a significant step towards sustainability with the launch of its Food Waste Smart Bin programme. Led by the Department of Public Works (DPW), the initiative introduces 30 rodent-proof, sensor-equipped composting bins across the city, providing 24/7 access for residents to drop off food scraps. This effort aligns with the District’s ambitious goal of diverting 80% of waste from disposal, reinforcing its commitment to zero waste and a circular economy.

A Community-Driven Approach to Composting

DC’s new Smart Bins were placed with community input to ensure they are easily accessible, especially for residents in multi-family housing who may not have had previous access to composting. By introducing convenient, unstaffed drop-off points, the city is building on its existing Compost DC programs, which include staffed Food Waste Drop-Off sites at farmers’ markets and a curbside compost collection service for 9,000 single-family homes.

Residents can locate their nearest Smart Bin and review composting guidelines at: www.zerowaste.dc.gov/foodwastedropoff

How Smart Bins Work

DC’s Smart Bin programme is designed to make composting simple and efficient.

  • Rodent-proof design – Bins are built to keep food waste securely contained to help prevent pest concerns.
  • Smart sensors – Each bin uses real-time monitoring to track capacity, so collections can be better timed and avoid unnecessary trips.
  • 24/7 accessibility – Residents can drop off food waste anytime using the metroKEY app or a keypad access code.

Supporting DC’s Circular Economy

The organic waste collected from Smart Bins, along with curbside and drop-off programmes, is processed into high-quality compost. This compost is then used by local farmers, landscapers, and community gardens or sold at local hardware stores and garden centres, helping improve soil health and reducing reliance on chemical fertilisers (source).

This initiative is part of Mayor Muriel Bowser’s broader waste reduction strategy, with $3 million allocated in the FY25 budget to maintain and potentially expand the city’s curbside composting programme. DPW Director Timothy Spriffs said that one-third of food produced in the U.S. is wasted.

“By installing food waste smart bins across the district, DPW is expanding access to food waste diversion opportunities for all district residents, an important step in helping to divert 80 percent of waste from disposal to achieve D.C.’s zero waste goals,” according to Spriffs.

Globally, about a third of all food goes to waste. In 2022 alone, a staggering 1.05 billion tons of food were wasted according to the United Nations Climate Change. This adds to the 8 to 10% of global greenhouse gases emitted during food production, transport, and decomposition.

Expanding Composting Infrastructure

DC’s Compost DC programme already plays a pivotal role in waste diversion, and the addition of Smart Bins strengthens that infrastructure. Besides the new bins, the city operates:

  • Twelve staffed Food Waste Drop-Off locations at farmers’ markets and community hubs on weekends.
  • A curbside compost collection programme serving 9,000 single-family households, with plans to expand.

These food waste drop-off services have been provided in DC since 2017 in its eight wards. By combining technology and community involvement into waste management, Washington, DC is proving that urban composting can be both practical and scalable.

A Model for Other Cities?

DC’s Smart Bin initiative sets a precedent for cities looking to increase composting access without rolling out new curbside collection services citywide. By leveraging smart technology, community collaboration, and existing infrastructure, Washington, DC is showing that innovative, cost-effective solutions can support waste diversion goals in urban environments.

As cities worldwide seek to improve sustainability, Washington, DC’s Smart Bin model could serve as a blueprint for integrating technology-driven composting solutions into municipal waste systems.

Washington, DC’s composting efforts have also been reinforced by local partnerships, including a collaboration with George Washington University to collect organic waste and expand composting accessibility.

A Model for Other Cities?

While Washington, DC advances its composting initiatives, other regions around the world are also finding new ways to handle organic waste.

Italy’s Industrial Composting Success

Italy has built a robust industrial composting system that includes compostable bioplastics in its waste management. With over 300 composting facilities and strict policies, Italy has already exceeded its 2025 and 2030 recycling targets for compostable materials.

Australia’s Government Initiatives in Composting

Australian governments have launched policies supporting composting at both state and federal levels. Investment in infrastructure, encouraging businesses to adopt compostable alternatives, and mandatory organics diversion from landfills are key strategies driving change.

New Zealand’s Evolving Waste Policy

New Zealand saw only one of its five key waste minimisation policies move forward in 2024: standardising materials accepted in recycling schemes. These recent policy changes highlight the complexities and challenges in balancing environmental goals with economic and logistical considerations.

South Australia’s Composting Research

South Australia is leading the way in composting, with recent research spotlighting its best practices for processing food and garden organics. Findings offer valuable insights for other cities and states looking to improve their waste diversion policies through programs like FOGO.

The Current Challenges in Implementing FOGO

These global efforts on waste minimisation show that cities and states can implement innovative solutions tailored to their local waste management challenges. Composting remains one of the many ways we can move towards a more sustainable and circular future in our communities.
