For a material recycling facility (MRF), the composition of the solid waste is given as: Paper – 30%; Plastics – 30%; and Food – 40%. Also, manual sorting is used to remove plastic waste with an efficiency of 85%. Following the manual sorting the solid waste is fed to a zigzag pulse air classifier for separating paper. The air classifier is expected to sort the paper at an efficiency of 90%. If the solid waste processed is 400 tonne/day, determine the quantities of all the products of solid waste processing.

Question

For a material recycling facility (MRF), the composition of the solid waste is given as:

  • Paper – 30%;
  • Plastics – 30%; and
  • Food – 40%.

Also, manual sorting is used to remove plastic waste with an efficiency of 85%. Following the manual sorting the solid waste is fed to a zigzag pulse air classifier for separating paper. The air classifier is expected to sort the paper at an efficiency of 90%. If the solid waste processed is 400 tonne/day, determine the quantities of all the products of solid waste processing.
