With its future at stake, New Zealand Foam Latex needed an economically viable and environmentally friendly fuel to produce steam needed to manufacture their products – all made from foam.
Coal was cheap, from $6.10/GJ. But emissions and the costs of mitigating them ruled it out. Diesel and LPG would cost over $30/GJ.
Wood was cost-effective and clean-burning. A variety of sources helped assure reliable supply - forestry hoggings, timberyard residues, left-over pallets and demolition, even dunnage reclaimed from shipping.
