EVALUATING THE AMOUNT OF PAH WITHIN WASTE-TO-ENERGY GENERATORS’S ASHES

Abstract

This paper mention the research of the ingredients within PAH in ashes of 2 incinerators at Viet Hung and Dan Phuong waste-to-energy factories. Choosing to analyzes 13 PAH according to Viet Nam National Standard 07:2009/BTNMT – The national standard in the limitation of dangerous emissions from: domestic wastes burned by martin, plasma technologies; industrial wastes mixed with hazardous wastes. Results shown: 13/13 PAH combinations exist in the ashes of the incinerators. The differences between PAH indicators is quite large, at max the differences is about 102 times. The PAH content at different samples rely upon: the type of entry wastes, temperature, burning technology. 13 sample analyze all show result below the limit of Viet Nam National Standard 07, so if we only look at PAH content the ash from the incinerators isn’t considered a hazardous emission. This is the basis for the factory and the government to create a management and processing progress which follow the national law of environmental protection.
