Fly ash

Fly ash material solidifies while suspended in the exhaust gases and is collected by electrostatic precipitators or filter bags. Since the particles solidify rapidly while suspended in the exhaust gases, fly ash particles are generally spherical in shape and range in size from 0.5 µm to 300 µm. to 300 µm.

Mechanochemical degradation of PCDD/Fs in fly ash …

 · Two distinct mechanochemical degradation (MCD) methods are adopted to eliminate the polychlorinated dibenzo-p-dioxins and -furans (PCDD/Fs) from fly ash in municipal solid waste incinerators. First, experiments are conducted in a planetary ball mill for selecting suitable additives, and an additive system of SiO 2 -Al is chosen for its high-efficiency, low-price, and good practicability.

Reusing Paper Sludge in the Fertilizer Industry

The processing of pulp and paper products yields a significant amount of waste in the form of sludge, collectively referred to as pulp and paper mill sludge, or PPMS. Historically, these residues have been landfilled or incinerated, but as disposal costs rise and sustainability becomes a requirement rather than an option, the industry is looking for a better way to manage them.
