A feature of MDF that may well see its use become more popular is its
"Environmental freindliness". Presently it is made primarily from
plantation grown Radiata Pine, though it can be successfully made from
almost any wood. Recycled paper, recycled scrap
wood, bamboo and materials such as carbon fibres, polymers, steel and
glass have all successfully been used in it's manufacture.
MDF is able to utilise young forest thinnings and sawmill offcuts that
would normally be of only limited value.
The use of MDF over hardwood is being promoted due to a worldwide
shortage of hardwood, and the areas where hardwood exists being touted
as areas of conservation value.
One presently contentious issue is the use of formaldeyde resins in the manufacture of MDF, and the healt risks assocciated. This is being overcome by the use of lignin based adhesives. Presently standards require that the emission of formaldehyde, which can cause eye or throat irritations, from finished products that contain formaldehyde be less than one part per million. This standard is being adhered to by most major manufacturers prior to its legislation.
