9EURO 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
