Korea-based skin care brand Siita has developed a new technology that speeds up the decomposition of its own biodegradable plastic waste, reportedly allowing the company to become a zero-waste enterprise.
The technology "accelerates the decomposition process of plastic from 500 years to just three months," per the company.

Siita recollects its containers via a portal on its website, on which consumers can register their spent packaging. The packaging comprises a biodegradable resin derived from a single raw material, according to the brand.
The collected material is pulverized down to 300 micrometer units, which is "optimal for complete composting," according to Siita. That material is then sent to the company's composting facilities.
The degraded containers ultimately "become high-quality, eco-friendly and organic compost" with no toxic components. This can then be fed to soil, imparting nitrogen and phosphoric acid.
Siita's range includes a Daily Facial Cream, Intensive Cream, Daily Cleanser and Daily Toner. Per the company, 90% of its sales are derived outside Korea.
