Japan's top paper manufacturers are getting in on the fight against plastic pollution, coming up with innovative, sustainable alternatives to items that aren't usually so eco-friendly.
A subsidiary of Nippon Paper Industries has developed a waterproof cardboard box as an alternative for polystyrene containers.
Nippon Paper Industries says the box can hold water without leaking for up to three weeks. Food processing firms are already using it to transport fish.
The president of subsidiary Nippon Tokai Industrial Paper Supply says they see opportunity in the broader push for sustainable products, and "plan to put a great deal of effort into tapping into these societal trends."
The Daio Paper Corporation, meanwhile, is looking to replace the plastics hooks and hangers in our homes with high-strength paper versions.
