Sometimes, the most effective environmental solutions are the simplest ones.
These mesh traps are installed at stormwater outlets to catch bottles, plastic packaging, cans, branches and other debris carried through city drains after heavy rain. Water can continue flowing through the mesh while larger waste gets trapped before it travels farther downstream.
The first two traps collected around 370 kilograms of debris — showing just how much rubbish can move through stormwater systems without most people ever noticing.
The results were encouraging enough for the system to be expanded. With five drainage nets now operating, more than 3.6 tonnes of waste and debris have reportedly been intercepted across dozens of cleanouts.
The biggest benefit is catching pollution before it reaches rivers and oceans. Once plastic enters waterways, currents can carry it enormous distances, while sunlight and waves can break larger pieces into smaller fragments that are much harder to remove.
When the nets fill up, workers can lift them out, remove the collected waste, separate recyclable materials and return the traps to service.
No futuristic technology. No complicated machinery. Just a reusable barrier positioned where pollution is trying to escape.
Sometimes, solving a huge environmental problem starts with one remarkably simple idea.
