In a number of industries where boards are used, the boards used are cellulose based and consist of fibres of particles pressed together with or without a binder to form a continuous matrix in sheet form. The properties of the board vary depending on the constituents and the processes used range from rigid to flexible materials of differing strength and durability. Cellulose based boards are the common choice on the basis of price, appearance and properties. There is scope to further improve the quality of these boards for current applications and also extend their range of use eg moulded items for the automotive and food applications. There is an incentive in finding a co-raw material and especially one from waste material, which on separation into its components is mostly fibre and minerals eg clay and chalk. The subsequent use in products allied to paper and board is a new concept which will require development of new techniques and equipment. As the price of the raw material (wood pulp) for cellulose board has increased dramatically, the success of the project will benefit the environment and help the commercial status of many European mills by turning a waste material which has been disposed of as land fill etc... over the past 20 years, into a cheap and useful raw material. The proposed project therefore aims to develop a process that can utilise both mechanical pulp rejects and cellulose fibres as co-raw materials, design and build equipment for cleaning the pulp and then fibre preparation. Develop a mixed fibre board of quality and greater utility than existing boards.
