Synopsis

This unit will equip students with the ability to evaluate new developments in the recycling of paper, and in the pumping of fibre suspensions, to evaluate the implications for the availability and use of recycled fibre of changes in patterns of collection and usage and of new legislation on recycling and to analyse the implications of flocculation for processing. This unit will examine the statistics and trends in collection and use of recycled fibre, the effects of recycling on the properties of the fibres, the flocculation of suspensions of fibres from hardwoods and softwoods and various pulping processes, factors influencing the pumping of fibre suspensions, removal of contaminants from recovered paper and virgin fibre using hydrocyclones and screens and the de-inking and brightening of recovered paper.

Outcomes

Learning objectives of this unit are that the student will:

  1. Acquire an increased knowledge and understanding of:
    • Recycling of paper; trading, mass balance and effect on properties
    • Flocculation and other properties of fibre suspensions
    • Pumping of fibre suspensions
    • Pulping of recycled paper
    • Contaminant removal from virgin and recycled fibre by hydrocyclones and screens
    • De-inking of recycled fibre suspensions
    • Chemical engineering aspects of pulp brightening

  1. Develop the skills required to:
    • Analyse new developments in recycling processes and make appropriate and innovative recommendations
    • Keep up to date with developments in recycling legislation and assess their relevance to and likely impact on specific commercial operations and markets

  1. Demonstrate the ability to:
    • Undertake in depth research of the literature on recycling, analyse the information obtained and produce a report which demonstrates understanding and insight
    • Organise practical experiments, make detailed observations of experiments, analyse the results and produce an accurate and detailed report
