Reject Waste Pellets of Paper Mills as Fuel and their Contribution to Greenhouse Gas (GHG)
The paper-recycling process of paper mills generates reject waste in the region of 5-25% of its raw material, depending on the recovered fiber quality and process used in the mill. We carried out an assessment of the paper industry’s reject waste pellets (RWP) as a boiler fuel. Reject waste was...

Summary: | The paper-recycling process
of paper mills generates reject waste in the region of 5-25% of its raw material, depending on the
recovered fiber quality and process used in the mill. We carried out an
assessment of the paper industry’s reject waste pellets (RWP) as a boiler fuel. Reject waste was
identified by means of sorting. The pelletizing of paper mills’ reject waste
is a solidification process, as it is easier to
store, handle, and transport solid waste. We analyzed the approximate
calorific value and the sulphur content
of reject waste pellets. The results showed that the components of reject waste are largely comprised of 51% fibers and 49% plastic.
The plastic components of are dominated
by the high density poly ethylene (HDPE)
plastic type. RWP contains a lot
of organic matter and has a high calorific value and low sulphur content, which
gives it the potential of being used
as fuel. Utilization of 10% RWP mixed with 90%
coal as boiler fuel could reduce CO2 gas as greenhouse gas (GHG) emissions by about 9%. |
