[BIZ STREAM SPECIAL EDITION] This series of special editions feature selected stories from BIZ STREAM's signature "On-Site" reports. This episode examines how advances in the recycling of bio-waste are playing a key role in creating a more circular society. We feature a Japanese company that has found a way to extract hydroxyapatite (a key ingredient in making toothpaste and cosmetics) from eggshells, and another company that is turning sugar cane and other waste products into biofuel.
