LITE MDF panel

The dataset is representative for the production processes used in 2021, in the country of production, Republic of Ireland. The data Quality Level, according to Table E.1 of EN 15804 +A2, Annex E, is as follows: • Geographical representativeness: Very Good. • Technical representativeness: Very Good. • Time representativeness: Good. Allocation of energy and electricity types and amounts to the various manufacturing processes has been provided by the manufacturers along with production waste. Allocation of impacts to the products is based on the product composition mass. Flows related to human activities such as employee transport are excluded. The construction of capital assets such as buildings, manufacture of machines and transportation systems are also excluded since the related flows are assumed to be negligible compared to the manufacture of the building material when compared to these systems over a full lifetime of operation. The cut-off criteria of section 6.3.6 of EN15804:2012+A2:2019 have been followed, where 99% of the total energy and materials are included, and the total neglected input flows for the modules reported on in the LCA are less than 5% of the energy usage and mass.

This EPD is carried out for the MEDITE LITE MDF panel. MEDITE MDF panels are manufactured in accordance with I.S. EN 622-5:2009, Fibrepanels – Specifications, Part 5: Requirements for dry processed panels (MDF). The constituent raw materials of the MDF panels comprise: wood logs, wood chips and additives such as MDI, urea, resin, fire retardant and wax. By weight, wood comprises 91%, additions 7% and water 2%. The intended use of the MDF panels is in the construction industry in structural and non-structural applications, such as flooring, roofing, walling, timber-frame sheathing, temporary works and external hoarding. MEDITE LITE MDF is manufactured by refining softwood chips into wood fibres and combining them with resin glue and other additives. The wood fibre is then conveyed and dried by hot air through tube driers. The dried fibre passes over a continuous weigh belt and is conveyed to fibre storage bins, ready for the next production stage. The wood fibre mat is then formed by even controlled spreading of the dried resinated wood fibre onto a continuously moving wire mesh belt. The depth and width of wood fibre mat is pre-set according to thickness, width and density required. The mat is then compressed to a more compact form, excess fibre is trimmed off the edges and recycled back into the wood fibre forming system. The fibre mat then moves through a continuous hot press which consists of an upper and lower continuously moving heated steel belt, the pressed panel is then cross-cut to the required size, then cooled, stacked and moved for either storage or sanding. This EPD also covers the transport to site and end-of-life stages. This covers: transport to site, and end-of-life transport from site, waste processing and waste disposal. In the end-of-life it is assumed 90% of the MDF is incinerated (C3 phase) and 10% of the MDF ends up in landfill (C4 phase).
