title: Bioferment residue: TG-FTIR study and cocombustion in a MSW incineration plant.
abstract: With fast development of industry large quantities of hazardous waste are produced in China. Today, incineration plays an important role in the disposal of hazardous waste. Co-incineration of some types of hazardous wastes with municipal solid waste (MSW) has been suggested in the Proposed Standards for Pollutants for MSW combustors in China, published in 2010. According to this proposal, coincinerated hazardous waste should have similar combustion characteristics with MSW, such as bioferment residue (HW02-276-001-02 in China Hazardous Waste List). In this study, residue from the production of hydrochloride salt spectinomycin, a bioferment process, was studied by thermogravimetric analysis (TGA) coupled with Fourier transform infrared (TG-FTIR) analysis. In TGA, the sample attains its final weight before 800 °C. No gaseous pollutants evolve in large amount during FTIR analysis. During test runs at a MSW incineration plant in Jinhua, Zhejiang Province, bioferment residue was added to MSW at a rate of 24 ton/day and fed to the circulated fluidized bed (CFB) incineration system with capacity of 500 ton/day MSW. The operating parameters and emissions were monitored. The system performance was obviously not affected by addition of bioferment residue to MSW/coal and the pollutant emissions met the Chinese standard, with or without addition of bioferment into feedstock.
