Chandigarh, November 30

The office of the Controller General of Patents, Designs and Trade Marks (CGPDTM), under the Department for Promotion of Industry and Internal Trade, has approved the patent of Mohali-based entrepreneur Amardeep Sharma, who had developed a machine that processes all types of waste, including wet and dry garbage, without any segregation. He said the end product came in the form of green coal known as RDF (refuse derived fuel), which has a greater calorific value than coal itself. TNS
