Toner cartridges (plastics, including OPC drums, blades, gears, case, and toner powder)
that we currently use and discard may cause soil contamination
and water pollution if they are left in a state containing various heavy metals.
The decomposition period of waste plastic takes about 500 years.
Korea spends on 700 ~ 800 billion won on importing cartridges from the US, Japan, China and other countries a year, which results in huge economic losses.
