While plastic has many valuable uses, we have become addicted to single-use or disposable plastic which results in severe environmental consequences. In total, half of all plastic produced is designed to be used only once and then thrown away. In all of the single-use plastic wastage, there is also a significant contribution of plastic pens, disposable or not. This adds up to a result where we decisively take up instant disposal instead of recycle or reuse. Pens, which are globally used as instruments for writing, are generally made of plastic. When these are discarded, they have a negative impact on the environment since there are no known ways to recycle the discarded pens. The plastic wastage arising from pens alone was amounted to 600-630 tonnes between 2017 and 2018, worldwide. This project aims at design and fabrication of an Automatic Ink Refilling Machine for used ball point pen refills to avoid the major wastage of plastic used in the manufacturing of the pens and making it reusable until the tip or ball wears out. The “Ink re-filler” machine is mechanically constructed with hydraulic actuation for the function and is interfaced via an electronically operated interface, enabling anybody to fill the ball point refills for reuse, under less than a minute and at low cost. This will also avoid the continual purchase of new refills and pens, since the cost of the ink of the pen is hardly lesser than 1% of total cost of the pen.
