Get your hands dirty. Keep your city clean.

Take the #trashtag data challenge using the TrashBlitz web app to collect data on the top polluting single-use plastic items. Identify brands in your neighborhood while cleaning up the area. This data will be modeled by 5 Gyres to give any city a comprehensive picture of what type of plastic pollution is entering their waterways.

Data Collection Days: April 20th & May 11th 
Solutions Summit: May 30th

April 20th: Join Friends of the LA RiverSurfrider LA, and Heal The Bay at their community organized cleanups along the watershed while using the TrashBlitz app.

May 11th: 5 Gyres led data collection sites:
Van Nuys: 10am-12pm
6300 Balboa Blvd
Lake Balboa Park

Los Angeles: 10am-12pm
751 Echo Park Ave
Echo Park Lake

If you can’t make either of the days of action but still want to get involved, contact to learn how.

The Story of TrashBlitz

We believe that solutions should not only be left to policymakers, and that science should not only be left to PhDs. We are all key stakeholders in the health and the future of our communities.

TrashBlitz is about providing a platform for all of us to unite around taking charge of waste in our communities, through gathering the data we need to identify problems and drive solutions locally.

Today, scientists and policymakers everywhere are understanding that ocean plastic pollution is a symptom of how plastic moves through communities on land, the way products and packaging are made, and the systems that capture waste (or not). This is the research frontier of science, the UN, governments and corporations, but it’s missing the voice of the people to frame and direct solutions that serve everyone.


Globally, we have been tracking the issue of plastic pollution in our oceans and communities for over 10 years. We have worked alongside our ambassador network around the world to document plastic firsthand, and leverage the data to drive upstream solutions. We have seen how small, local engagement can scale to drive statewide and even national change, as in the case of plastic bags in California, and the National Microbeads Free Water Act of 2015. And we have seen an explosion of global interest, messaging, solutions, and data emerge on plastic pollution.

But we have also heard from many stakeholders that while global datasets are informative, what’s needed to drive change in communities is local data: what’s in our backyard? And what local knowledge, innovation, or expertise can we tap into to drive local change?

This is where grassroots mobilization will engage in collecting meaningful data and bring it to government and corporate leaders with the solutions that work best for all.
