Plastic Waste Management Technologies
Please give more details of new technical application area:
Current invention will help in improving the catalytic properties by restoring the activity for longer period of time as well as with the product selectivity. The waste plastic is believed to have lots of impurities which often lead to the deactivation of catalyst during catalytic cracking very rapidly. Thus, pretreatment of plastics can be one of the options to improvise the catalyst utilization for the defined product formation. The research incorporates the novel process of thermo-catalytic cracking of waste plastic for the fuel range liquid formation. Thermal treatment of plastics will lead to the generation of vapours which are supposed to come in contact with the catalyst for further cracking followed by the condensation of gaseous fraction forming liquid products.
Organization(s):
Indian Institute of Technology (IIT) Delhi
Affiliated Ministry: DRDO, Govt of India
Type of technology development: Indigenous
Does the technology help in replacing any import items currently
procured from outside India?
No
Does the technology have export potential? Yes
Category of Technology developed: Futuristic
Stage of Development: Prototype Level
Please describe in detail including the TRL Level:
Use of waste plastics may bring many societal benefits offering future technological advances, however concerns about plastic waste disposal are diverse accumulation of waste in landfills, natural habitats, physical problems for wildlife due to plastic ingestion or entanglement, leaching of chemicals from plastic products and their transfer to wildlife and humans. Eventually, overriding concern about our current plastic usage is not sustainable. Technology developed by our team addresses all above concerns through plastic waste valorisation converting it into useful low cost cleaner fuel. The developed process is sustainable at the prototype level and can be taken forward to field test.

    Abstract:

Applications: 1. 100 percent conversion of waste plastic to fuel range hydrocarbons. 2. 75 percent low cost liquid fuel and 25 percent combustible gases are obtained. 3. The minimal operating parameters such as temperature catalyst intake and gas flow rate compared to existing technologies. 4. Overall process runs at minimum energy consumption (No external H2 source), with maximum energy output and efficiency. 5. No waste by products are obtained in the overall process. 6. Commercial pricing of the process and the end product as calculated through techno economic analysis is around Rs 45 to 55 only. 7. No potential competitor exists at this conversion rate as well as economically viable benefits.
Advantages: 1. The present invention has the advantage over other claimed processes in respect of operating temperature, the ratio of plastic to the catalyst, use of transition metal modified zeolite catalyst, reaction duration, yield of liquid product, and catalyst recyclability. 2. The fixed bed reactor setup is mainly distributed into two zones of heating i.e thermal cracking and catalytic cracking. 3. The separated zones prevent the catalyst form the direct contact with the impurities present in the waste plastic. This prevents the early poison of the catalysts. 4. More refined and low cost can be obtained.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
