Conversion of paper mill sludge into pelletised composite activated sorbent

Objective

There are currently more than 1.200 paper mills in the EU, each generating from between 10and over 100 dry tons of paper mill sludge or filter cake (FC) each day. This project focuses on converting paper mill sludge or filter cake (FC), which is typically landfilled or incinerated and is a major environmental concern, into pelletised, composite sorbent of activated carbon and highly porous cay. The composite-activated sorbent (CAS) is especially suitable or the purification of industrial waste water, such as paper mill effluent prior to discharge. The proposed two-stage technique involves segregated fluidised-bed pyroysis, with programmed heating at a relatively low temperature to maximise char yield (carbon retention is critical to low-carbon feedstock of FC) and combustion of pyrolysis gases at a higher temperate, with H20 and CO2 as the main gaseous products.
