EURO PAPER

• keen to exploit principles of industrial ecology
• mutually-sustaining association of industries
  brought together to minimise raw material use and
  waste
• eco-park concept, usually centred around an
  energy production facility, eg at Kalundberg in
  Denmark
• reject waste stream
• continue to improve fibre removal and maximise
  plastic content
• improved combustibility with a view to energy
  recovery in some form
• sludge waste stream
• content with its approach to land application,
  but wants other proven options
• fortunate location with nearby cement works, but
  want to retain ownership of waste and not be
  reliant on others
• collaboration with nearby mills to develop
  regional plant for energy and filler recovery and
  new machine to manufacture PW using DIP and
  recovered filler
