This document provides an up-dated progress report on our development of pigment emulsified creosote (PEC) used as a cleaner alternative to conventional high temperature creosote. A range of commodities (both hardwood and softwood) has now been satisfactorily treated in pilot plant and full scale commercial operations. Both brown (PEC 30B) and white (PEC 30W) formulations have been used. In addition a number of biocides have been added to PEC 30B in order that wood may be treated to lower overall creosote levels while still retaining full preservation performance. It is anticipated that PEC will be used to treat a wide range of hardwood and softwood commodities.
