Alternative fuel vs environment

THIS is apropos of the news item in media ‘Cement plants mull used tyres as source of fuel’. There are published studies on environmental risks of using TDF. One such report is Soil, Water, and Air Environmental Impact from Tyre Rubber/Coal Fluidised-Bed Co-combustion.That report concludes, as noted in Wikipedia, “atmospheric contamination dramatically increases when tyre rubber is used as fuel. Other different combustion variables compared to the ones used for coal combustion should be used to avoid atmospheric contamination by toxic, mutagenic, and carcinogenic pollutants, as well as hot-gas cleaning systems and Cox capture systems.”While the private sector is keen to keep its factories running in these difficult times, environmental authorities need to ensure that no one ends up making this country one big poisonous gas chamber.@Raza Jaffri — Dawn
