Engineer Chitra Thiyagarajan Developed Machine Which Converts Plastic Waste into Diesel

Posted by Siva Kumar Ari
An Engineer 'Chitra Thiyagarajan' has developed a machine which converts plastic waste into diesel . She is determined to find a cheap and sustainable fuel, She has finally developed a unit that converts plastic waste into a fuel similar to diesel. After a series of tests in a sustained three-year effort, Thiyagarajan finally perfected the device and applied for a patent.
Engineer Chitra Thiyagarajan Developed Machine Which Converts Plastic Waste into Diesel

Chitra Thiyagarajan's guide is Mr. C S M Sundaram (80 years ) a retired professor of St Xavier's College, Mumbai,  He said the device was the result of backbreaking work, persistence and dogged tenacity. It involved research, fieldwork and frequent upgrading of design, I may have helped her occasionally but the credit is all hers.

Chitra Thiyagarajan applied for a patent for the device in June month 2013. The patent authorities checked the machine for two months and verified that it could be patented. They accepted my application in August month of 2013.

Explaining how her 'pyro-plant' functions, she said, all plastics except PET bottles are put in a chamber and heated in the absence of oxygen over chromium micro band heaters (similar to those used in water immersion rods) to temperatures of between 350oC and 375oC. The gas generated passes into another chamber with a water coolants coils on two sides. It is then pumped into another compartment half-filled with water. The fuel floats on the surface. Non-soluble gas that passes into a condenser can be used as an LPG alternative.

The device is not expensive and requires just three hours to generate fuel. A 5kg unit costs around Rs 75,000 and a 25kg variant, Rs3 lakh. Each kg of plastic produces 800ml of diesel. While the diesel can be stored, the LPG generated has to be used directly and cannot be compressed,  A similar process is used to generate fuel in China but the production costs are high and it is a time-consuming process," Chitra Thiyagarajan said.

Indian Institute of Technology-Madras chemical engineering professor S Pushpavanam said the invention is feasible and could be used to produce fuel. Thiyagarajan's other inventions include a night vision camera and an electromagnetic belt for physiotherapy.

  7. Ms. Chitra, first of hats off to you...Hope you get due recognition and support from government to bring your machine to everybody's home. In the volatile fuel price market nowadays your invention is a savior to India and also to all developing countries that are dependent on western market for their fuel supplies.

    My kind suggestion, Establish your own company once you get your patent, look for good sponsors and produce it on a large basis and kill the fuel crisis. But be aware of the fact my friend, all big fuel companies might discourage your effort. Lets hope for the best, May God be with you.

  9. Good machine to convert city plastic into diesel. How about commercial apllication???
    If investment is more to produce meager quantities of fuel, it will not suceed
