Dar es Salaam. Researchers from the University of Dar es Salaam (UDSM) have unveiled a range of locally developed technologies aimed at reducing construction costs, lowering carbon emissions and improving energy efficiency as Tanzania seeks sustainable solutions for the construction and energy sectors.
Speaking to The Citizen yesterday at the ongoing 50th Dar es Salaam International Trade Fair (DITF), laboratory scientist Mr Jason Kaijage said the technologies were designed to tackle climate change through environmentally friendly alternatives to conventional construction materials and processes.
Among the innovations is Duracem, a cold asphalt technology for road construction and maintenance. Unlike conventional asphalt, which requires heating before application, the product can be used without heating, reducing emissions and cutting costs.
Mr Kaijage said the technology could lower road construction costs by between 20 and 25 percent while allowing roads to reopen within two to three hours after application.
“Conventional asphalt releases harmful gases during heating and increases construction costs. Our cold asphalt is cheaper and environmentally friendly,” he said.
