The Litterboom Project, a South African initiative that uses floating barriers to intercept river plastic, has received a Defender Conservation Award. The recognition includes a £100,000 bursary, a vehicle, and access to mentorship to support the expansion of its operations into remote river systems.
Why it matters
This award highlights the effectiveness of localized, infrastructure-based interventions in preventing plastic waste from reaching marine environments. By scaling these proven river-interception methods, the project aims to address the significant volume of pollutants currently flowing through urban South African waterways.
The Litterboom Project currently removes 5 tonnes of waste monthly from the Tongaat, Umhlanga, Umgeni, and Umbilo rivers. The team uses physical floating barriers designed to block debris from exiting river mouths into the ocean.
The players
The Litterboom Project
A South African environmental initiative that installs floating river barriers to capture plastic waste before it enters the ocean.
Defender Conservation Award
An international grant program that provides funding, equipment, and mentorship to environmental projects.
The details
The project uses floating barriers, a simple physical obstruction that spans the width of a waterway to trap surface-level solid waste while allowing water flow to continue. Once intercepted, teams perform regular clean-ups to remove the accumulated plastic and refuse from the barriers. This method prevents non-biodegradable debris from reaching sensitive coastal ecosystems and open water.

The Tech Race
This initiative represents a move toward localized, high-impact mechanical interventions in the broader struggle against marine plastic proliferation. It aligns with global strategies to prioritize upstream capture before waste degrades into microplastics.
The project plans to use its new funding to reach remote river systems, potentially reducing plastic pollution in regions previously lacking formal waste management infrastructure. There are currently no direct operational changes for the public as the project focuses on industrial-scale river management.
The takeaway
The project demonstrates that physical, low-tech barriers in key river channels can yield significant waste reduction results. Watch for the project to announce new installation sites in remote regions as they deploy their £100,000 bursary in the coming year.
