Pencil Printer to Reuse Unwanted Pencils

Stubby or worn-down, used pencils don’t have to end up in landfills anymore, as Hoyoung Lee has invented a pencil printer to creatively reuse unwanted pencils.

Toner News reports the innovative printer is environment-friendly, as it replaces toner cartridges with lead from unwanted pencils to print text, and meanwhile use the erase portion to erase typo mistakes after printing. It is estimated that more than 350 million toner cartridges are consumed each year and end up in landfills.

When using the pencil printer, users simply insert the pencil stub into the appropriate port to have it grounded. Heat is applied to separate the wood from the lead. While the lead is used for the printing function, the worn down eraser on the end of the pencil is also reused and ends up in the eraser cartridge, allowing users to correct mistakes and save paper. With the curved design, the eraser dust would just drop down the side of the paper without affecting the printing.
