SR132 Environmental inventory of three common NZ composite sheet materials (2004)

A truncated life-cycle inventory study of the three common types of New Zealand-produced wood-fibre-based composite boards (fibre-cement board, medium-density fibre-board and plywood sheeting) was conducted and an examination of the three composite boards from raw material acquisition through to the finished product on the factory floor was made.

The environmental aspects investigated were: energy and material inputs and discharges to air, land and water. An environmental profile was derived, listing all the major inputs and outputs in the production of 1 kg or 1 tonne of respective composite board.
