Experts say about two liters of oil are necessary to produce a single pound of toner powder – the amount required for each oil-based cartridge. 100 million such toner cartridges are used every year by various institutions in the US alone, which directly translates to over 50,000 tons of the petroleum-based substance.
Soy ink in itself isn’t a new concept – in fact, it is today used in over 95 percent of America’s daily newspapers, while about one quarter of commercial printers regularly operate on soy ink. However, it is the first time a technology is introduced, which allows soy-based substance to be used in laser cartridges. PRC says its products, which can be identified by the “SoyPrint” label, are already compatible with the most popular brands of laser printers found on the market. “Now every office employee can help reduce dependence on oil every time they put a toner cartridge in their printer” – said Debe Overhaug, president of PRC.
