SEOUL, Feb. 16 (Korea Bizwire)Face masks that used to symbolize the pandemic era are now turning into a source of environmental harm.

The Anti-Corruption and Civil Rights Commission (ACRC) reported that each South Korean citizen used a new disposable mask every 2.3 days on average last year. More than 7.3 billion masks were thrown away in a single year.

Disposable masks are typically made from polypropylene, a synthetic resin produced by polymerization of propylene. It takes around 450 years for them to decompose.

Burning them is also a problem. The U.S. Environmental Protection Agency reported that burning 1 ton of masks emits 3.07 tons of greenhouse gas.

The ACRC has made a policy proposal to find ways to recycle used masks, after ensuring public health safety.

Kolon Industries Inc., a textile and chemical materials maker, estimates that recycling used masks to produce 1 ton of polypropylene products will cut carbon emissions by 2.7 tons.

Profitability is the issue at hand. Recycling 1 kilogram of used masks can produce recycled pellets worth 100 won (US$77,940).

Separating non-plastic parts, such as metal pins, from used masks is quite costly. For now, mask recycling companies can barely make a profit.

Lowering the cost of recycling, and higher demand among companies and consumers for products made from recycled pellets are seen as crucial to overcoming the current situation.
