[font=-apple-system, system-ui, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen-Sans, Ubuntu, Cantarell, 'Helvetica Neue', sans-serif]how about making a machine, which takes a printed paper from one side and gives back a completely blank sheet back ?[/font]
[font=-apple-system, system-ui, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen-Sans, Ubuntu, Cantarell, 'Helvetica Neue', sans-serif]From my personal experience in college and now in office, I have seen people (Including me) taking a lot of prints everyday, however eco-friendly one tries to be, some work needs to be done on hard copies.[/font]
[font=-apple-system, system-ui, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen-Sans, Ubuntu, Cantarell, 'Helvetica Neue', sans-serif]Majority of the print-outs taken are for temporary work and goes to garbage ultimately. My major concern is to reduce this wastage. Using conventional paper recycling takes lot of time and also degrades the quality of the paper.[/font]
