Plastic is widely used in food industry: plastic bags, beverage bottles, packaging boxes, cling film...What's troubling is that plastic is difficult to degrade, leading to an increasingly severe problem of "white pollution." Now, with the revolutionary technology of "photodegradation degradation," there's no need for high-temperature and high-pressure conditions, nor for sorting and cleaning. Discarded plastic can easily degrade, while also producing byproducts for manufacturing new plastics. In Hainan, this technology is transitioning from the laboratory to comprehensive industrialization.

Technology will surely provide a solution to environmental problems such as carbon emissions and plastic pollution. What are the challenges to sustainability in business practice? What solutions does technology bring? Taking a look around the world, what advanced sustainable business models are worth learning from?
