#8. Pencil Pusher
According to Clean Air Council, American businesses use about 21 million tons of paper every year. Now a Chinese trip hopes to change that with their P&P Office Waste Paper Processor which turns paper into recycled pencils. But it doesn’t seem to have any practical implications, after all, most businesses take notes of their tablets and laptops.
#9. Perpetual Printers
Traditional printers require a lot of paper and expensive inks and toners. But a Japanese company called Sanwa Newtec is offering its own kind of inkless, tonerless and re-writable printers called PrePeat rewritable printer. A single sheet of paper can be used 1000 times before being replaced. Sounds great but there is a catch. It is so expensive that most offices will not be able to afford it. A single printer costs about $6,000 while a pack of 1000 sheet costs over $3,300.
#10. Hemp Fuel
Hemp is usually associated with marijuana and hence carries a bad reputation. Ethanol can be extracted from hemp which can be used as fuel. But due to hemp’s reputation, ethanol is extracted from corn which is slightly less efficient than the former process.
