According to results of weekly and monthly
monitorings of Grease & Oil content in wastewater
done in 2019, the Grease & Oil content in wastewater
had increased to be within the standard determined
by law throughout the year.
According to the graph, the volume of valueless waste requiring
disposal constantly decreased from 2015 to 2019 by 0.063 Ton /
Final compound or 39.43% and the volume of waste decreased
by 0.0001 Ton / Final compound or 1.30% compared to 2018.
Another activity which can reduce carbon black waste
is monthly rotary feeder cleaning. This activity would
reduce blockage in rotary feeder and allow the carbon
black to flow through rotary feeder smoothly.
