The company develops and deploys large-scale systems to efficiently concentrate plastic for periodic removal. The plastic is tracked and traced through DNV's chain of custody model to certify claims of origin when recycling it into new products. The company has developed a portfolio of interceptor solutions to halt and extract riverine plastic before it reaches the ocean.
