Technology developed: Development of sustainable technology for recycling of e-waste (TP19769495192)
Category: Technology Service/Know how
Details of Inventor(s):
Inventor Institution/Organization/Company Department Designation
Prof. K. K. Pant Indian Institute of Technology Delhi Chemical Engineering Professor
Technical Application Area: E-Waste technologies
If 'Other', please specify:
Please give more details of new technical application area:
Organization(s):
Indian Institute of Technology (IIT) Delhi
NA
Affiliated Ministry: DST, 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: Immediate Deployment
Stage of Development: Prototype Level
Please describe in detail including the TRL Level:
A pilot plant with a capacity of 10 kg per hour has been installed at IIT Delhi campus for recycling electronic waste. The facility pyrolyzes the polymeric fraction of the electronic waste into oil and combustible gases in an environment friendly manner. TRL Level -4

    Abstract:

Applications: Reduction of electronic waste. Extraction of metals from electronic waste. Thermal conversion of plastics into oil and combustible gases.
Advantages: Pyrolysis efficiently converts the organic parts of e-waste into valuable products. Pyrolysis also helps in enhancing the separation of the metallic fraction. High amounts of metals can be recovered using this technique with high selectivity, low energy consumption, and low cost. The amount of generation of toxic and corrosive effluent is also minimal in low-temperature roasting technique.

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.
