PRODUCTION OF REFINED CELLULOSE FIBRE FROM WASTE MATERIALS

摘要

A method of treating fibres produced by the thermal treatment of waste materials, which method includes, drying the fibres such that the moisture content of the fibre is in the range of from 4 to 15% by weight of the fibre and substantially removing debris (such as grit and/or plastics material) from the treated fibre. Optionally the size of the refined treated fibre is reduced to a length typically less than about 35mm and preferably less than 25mm. The fibres are preferably cellulose material from mixed vegetable matter. The fiber may be graded according to its density by an air current separator. Also claimed is a method of producing refined cellulose material, which material may be agglomerated with a binder and used in the manufacture of fuel.
