Catalyst cuts dioxin emissions from incinerators

The German chemical company BASF has developed a catalytic process to abate dioxin emissions from incinerators. The technology is claimed to have a high destruction efficiency, and appears to bear out the German Government's technology-forcing approach to pollution control standards.

In 1991, the German authorities set a tight dioxin emission limit of 0.1ng/m3, expressed as a toxic equivalent (TEQ) of the most toxic dioxin isomer, 2,3,7,8-TCDD, to be achieved by 1996. At the time there were no proven technologies able to meet the limit.

In the UK, HM Inspectorate of Pollution (HMIP) has set a limit of 1ng/m3 TEQ, to apply to existing incinerators from December 1996 (ENDS Report 209, pp 26-28
