KARACHI: Ideas for innovative solutions to day-to-day pressing issues drew large numbers of visitors over the two days of the Research and Technology Showcase 2022 exhibition jointly organised by NED University of Engineering and Technology and Sindh Higher Education Commission at Expo Centre that concluded on Friday.
Thirty-two universities from across the province participated in the show with 340 locally-developed technologies. A significant number of these projects were initiatives taken up with an aim to find solutions to the several pressing issues Pakistan currently face.
“Considering the fact that our country lacks low-cost efficient technologies for water purification and wastewater recycling, our team has developed ion exchange membranes, currently being imported at a high cost. These special membranes transport certain dissolved ions while blocking other ions or neutral molecules,” explained Dr Shazia Perveen of the NED university’s chemistry department.
Trials had been completed and funding assistance was needed to start commercial production of the membrane, she added.
At another stall, students of the NED university’s civil engineering department had put on display samples of limestone calcined clay cement which could reduce carbon dioxide emissions by more than 30 per cent compared to the ordinary cement.
“This blended cement produced for the first time in Pakistan by using local raw material has demonstrated greater durability,” Mohammad Hasan Khan and...
