“The second system, which is newer and has not been tried extensively, is known as pyrolysis or gasification.”

“And what about the residuals of emerging processes like gasification, enzymatic hydrolysis, depolymerization, biodiesel production, etc?”

“It is also frequently found in coal gasification and oil-refining processes as well as industrial gas turbines operating on impure fuel.”

“The gasifier works by feeding wood waste through the floor and into the centre of a dome-shaped refractory-lined gasifier.”

“The higher velocity fluidization regime means that there is a particle density gradient from the bottom of the gasifier to the top.”

“One method involves a device called a plasma arc gasifier, which generates artificial lightning bolts between two electrodes.”
