The basis of moulded fibre is paper fibre. Moulded fibre products, such as egg cartons and fruit packaging, are made from a "mush" of paper and water. To be more precise, what we are talking about here is vegetable fibres, which are subdivided into primary and secondary fibres. Primary fibres are wood fibres from trees which have grown for several years. These are only used to a very limited extent in the manufacture of moulded fibre.
Secondary fibre materials make up the biggest percentage by a long way. Foremost in this category is waste paper, which is traded in 40 different classes throughout Europe. The moulded fibre industry alone ensures that approx. 200,000 tonnes of it are ecologically recycled every year.
