Change in Human Behavior Towards a Clean Dhaka

The Dhaka North City Corporation and Dhaka South City Corporation installed around 6,000 waste bins across the city in 2016 but the project failed within a year due to a lack of awareness of the citizens. So, any waste management project in Dhaka require behavioural change of it's citizens.

Creating ink cartridges from recycling plastic wastes

The objective outlines the strategy and mechanism of creating a circular economy by converting plastic wastes into ink cartridges

Solution context

Bangladesh generates 633,129 tons of plastic waste annually and clearly Dhaka as a division creates more waste than any other division being its capital city. These wastes are ultimately dumped as landfills which create a harmful substance called Leachate. Leachate is not just only harmful for the environment but also promotes severe health risks. Also water dredging has nowadays become very difficult due to excess clumping of plastics underwater. Hence, Team Pragmatic has come up with a feasible solution which emphasizes on circular economy because it believes in recycling non-biodegradable products. The plastic wastes generated from educational institutions like universities or schools, offices, supermarkets etc. such as water bottles, plates, straws, glasses, pens (that has run out of ink), spoons, unwanted files, plastic foams rigid plastics (like pipes, crates, expanded polystyrene packaging etc.) will be collected by our plastic recycling organization/start-up and would create ink cartridges out of these plastic wastes which is a process known as 'secondary recycling'. The ink cartridges will be sold to the same institutions we had previously borrowed plastic wastes from at a discounted price. In this way, their costs will be reduced and we will be able to earn by selling ink cartridges to these institutions.

Solution description

The solution follows the process of converting plastic wastes into ink and later making them into ink cartridges. The process involves:-

1) Shredding:- Making paint from plastic recycling

2) Sorting:- Adding dyes to the sorted colored and uncolored part from the shredded materials

3) Removal of Colored Caps: - These colored caps are made of up another type of plastic which floats. Straining of these floating caps add an optimum and qualified ink.

4) Removal of Labels:- The shredded pieces emits soda bath which are hazardous to the skin therefore the corrosive properties must be carefully removed.

5) Drying:- The clean shredded pieces are dried in a rotator which usually takes up to 10 hours. This is done in order to remove the excess water flowing out of the shredded pieces and the drying is done to remove the wetness without damaging the quality.

6) Melting:- This process ensures there will be no clumps in the paint. At 270 Degrees Celsius the shredded pieces are melted which outcomes to the smooth application to the apparel paint.

7) Adding colors:- The last and final step is to add colors to the manufactured paint.
