Electronic waste or e-waste describes discarded electrical or electronic devices. Used electronics which are destined for reuse, resale, salvage, recycling, or disposal are also considered e-waste. E-waste is the most dangerous wastes of all because it contains a plastic which does not decompose easily and the other part toxics like lead, mercury, and cadmium which are very dangerous to soil or the environment if they are not managed well. Managing them requires a big budget and very complex methodology so many companies pay to dump in some places because it is not profitable to manage. The problem is first extracting the plastic is hard from the e-waste.

Electrical wires are usually covered with insulating materials, such as plastic, rubber-like polymers, or varnish. Insulating and jacketing of wires and cables is nowadays done by passing them through an extruder. Formerly, materials used for insulation included treated cloth or paper and various oil-based products. The arbitrary melting point ratings of plastics are no more than a guide as to whether plastic is qualified to be used in an electromechanical cable at its rated melting point. For example, DuPont Teflon- FEP-100 has a nominal melting point of 510 F or 265.556 degrees Celsius. There are mainly 5 types of wire: The main our main interest is on a widely used Copper wire. Copper has a relatively high melting point of 1,085 degrees Celsius (1,982 F).

This tells us that insulators have a lower melting point than the wire. Therefore, by developing a home use device that can generate a maximum of 266 degrees Celsius to sort plastic from the e-waste. This way companies do not have to work on the extraction of plastic from e-waste for recycling. This makes the recycling business and plastic waste management way better. I am designing a mechanism that will extract plastics from home use e-wastes especially cables by generating enough heat to melt the plastic but not the wire inside the cable. This way all peoples can sell the plastic and the wire and contribute to plastic waste management process and profit at the same time.

    I have dedicated my life for invention and research because not only I have big dreams but also it is my only way out of poverty. We all have a talent we know or did not find out yet. Mine happens to be inventing. I discovered this talent of mine when I was in second year student during my university life. Starting from that point everything seemed not important except creating new ideas. So, until now I have invented more than 50 inventions which are new to the world and the rest are intended for Ethiopia that will change the life of many people including mine. But because of poverty, theft and many reasons I could not manage to make it. But all that matter is I will never give up. I will invent until and after I become successful. That makes me a strong entrepreneur. My skills are aided with a mechanical engineering degree on design, production and sales expertise. You can find some of my inventions via
