Abstract Medium density fibreboards (MDF) are currently not recycled after service life, but various publications report on recycling by the disintegration of MDF using techniques and properties obtained recovered fibres (RF). In this study, main aim was to put back RF into manufacturing process as closed-loop repeated thermo-hydrolytic disintegration. Compared previous studies, focus with a re...

In this study, ironwood (Casuarina equisetifolia L.) raw material was used. 1.17 moles of urea-formaldehyde (UF) resin (12.5%), solid paraffin (1.5%) and 10% ammonium chloride solution were added to the fibers. Boards with a density 0.694 g/cm³ produced in MDF production line. The physical mechanical properties boards evaluated. Swelling thickness for 2 24 h 2.53% 6.01%, respectively. Modulus r...

The purpose of this study is to develop a low-formaldehyde-emitting resin system for medium density fibreboards (MDF). A combination of polyamines with phenolic resins seems to be suitable for this purpose. To produce panels with such a resin system, polyethylenimine, and a phenolic resin were separately applied on fibres and subsequently made into boards in a thermal pressing process. It was d...

Paper is a thin material mainly used for writing, printing and packaging. The stem fruit of two Musa species: Acuminata balbisiana (Banana stem) Paradisiaca (Plantain were expended. chips charged into digester with different percentages (5, 10 15 %) sodium hydroxide (NaOH) subjected to the impregnating temperature (60oC) 1-hour before heating 100oC 3-hour. stems pounded finely mortar pestle the...
