On Monday, January 18th the nation celebrated the life and legacy of Doctor Martin Luther King Jr. as “a day on, not a day off.”

The MLK day of service honors Dr. Martin Luther King, Jr’s work dismantling the systemic racism that legislation alone could not solve. It is the only federal holiday designated as a national day of service to encourage all Americans to volunteer to improve their communities.

For MLK Day of Service 2021, the litter intelligence company Litterati had a role to play too. We believe every single one of us has the right to a clean and healthy environment and we’re on a mission to make the invisibile of waste and litter visible.

The challenges hosted on the Litterati platform make it possible for anyone to use the data and experiences from litter cleanups to fuel community pride, collective power, and civic advocacy to make equity real.


From all over the US, 19 challenges were started in cities across Pennsylvania, Texas, Tennessee, Washington, and California.

Community challenges were created by municipal groups and NGOs, while another third of challenges nationwide were started independently by community members. 4 major corporate partner organizations also took part in local community challenges.

In total, thousands of pieces of litter were cleaned during the Dr. Martin Luther King Day of Service, with some communities continuing their efforts throughout the entire month of January.

The data collected will give these communities the insights they need to prevent litter at its source and create systemic change to ensure that all people have the right to clean neighborhoods.
