Bohol adopted a free app that maps plastic from photos of basura. Here is how it works.
The UP Marine Science Institute signed with Bohol and Bohol Island State University on July 31 to roll out PlastiZen Basura Patroller. You open it, snap the litter, and submit anonymously.
The province of Bohol is now using a phone app to find out where its plastic trash actually piles up. The University of the Philippines Marine Science Institute said it signed an agreement on July 31 with the Provincial Government of Bohol and Bohol Island State University to deploy an app called PlastiZen Basura Patroller across the province. It was funded by the Department of Science and Technology, co-implemented by UP Baguio, and it is on Google Play.
The app asks almost nothing of you. Its own instructions are three lines: open the app, snap a photo of the litter, submit anonymously. The photo carries the location with it, so every submission tells the province two things at once, what the trash is and exactly where it was sitting.
What citizen science actually means
Citizen science is a plain idea with a formal name. Instead of paying a small team of researchers to walk every shoreline, you let thousands of ordinary people each report the one spot in front of them. Nobody needs training, a lab, or a job title. The value is in the volume.
The submissions do not just sit in the app. They feed PlastiCount Pilipinas, an open source tracker launched in 2022 that keeps a repository, assisted by artificial intelligence, of both microplastic and macroplastic pollution trends. Bohol will run the tool through its Provincial Environment Management Office, and UP Diliman handles the handover: training, technical guidance, and where the data is stored.
Why it matters to Bohol
Bohol is a UNESCO Global Geopark, and its money comes off the coast. Officials said the location tags let them aim cleanups and spending at the places that are actually leaking waste into the water, rather than spreading effort evenly across a province where the problem is not even. The project sits under the national plan for marine litter, which sets a target of zero waste in Philippine waters by 2040.
The catch to watch
Mapping trash is not the same as removing it. The app produces a picture of the problem, and someone still has to fund the trucks and the people. Two other things are worth noting: the launch covers Google Play, and no iPhone version was announced. And a citizen science app is only as good as the number of people who keep opening it, which is the part no agreement can guarantee.
