TPI Polene claims waste-fuelled power is unsustainable07 November 2018, Published under Cement NewsTPI Polene has complained about the quality of national waste sorting in Thailand. The company has invested about THB4bn (US$121.9m) in waste-fuelled power plants. But high operational costs, including sorting, make the waste-to-energy business unsustainable, says the Thai cement producer. The lack of sorting means that Thailand's wet and damp waste can only generate about 1200kcal of energy when it is burned in the cement kiln. Japanese cement kilns generate 4000kcal from sorted waste f... |
