Suzuki has announced what it says is the world’s first microplastics collection system for outboard motors as part of the International Boatbuilders’ Exhibition and Conference (IBEX) virtual trade show.
No Effect on Cooling
The system consists of an inline filter installed on the engine’s cooling-water outlet and collects microplastics and other tiny bits of debris sucked in by the engine as it runs. The filter and associated plumbing fit under the cowling of Suzuki outboard models rated at 40 hp and higher. The system includes a bypass channel that allows unhindered engine operation if the filter becomes clogged.
Suzuki says the system is designed to have no impact on an engine’s performance or cooling efficiency. It has been tested extensively in Japan and the company says its research has been expanded and improvements will be made. The system has proven capable of collecting micro-particle pollution including urethane, nylon and wood chips. The filter package will initially be offered as an optional accessory with 2021 model-year engines and Suzuki is reportedly planning to make it standard in the future.
Marine biologists have long acknowledged the threat that microplastics pose to fish, marine mammals and wildlife. The problem isn’t going away and it’s negatively impacting oceans around the world. Suzuki says that combating the problem will require a cooperative effort by industry, the scientific community and outdoor enthusiasts. The manufacturer says the filtering technology developed for its outboards is a first step.
The announcement of the filter coincides with the launch of Suzuki’s Clean Ocean Project, which is a global initiative to reduce plastic waste and its effects on the marine environment. As part of that initiative, Suzuki has committed to reducing the use of plastics in the packaging of materials in its outboards and parts. The manufacturer says this could cut plastic usage by up to 2.3 tons each year.
