Since December 1996. Clean Technology Solutions Pty Ltd. Running own consulting engineering company specializing in materials and energy conservation.

June 1996 - November 1996 Manager Technology Development, Australian Paper Fine Papers Development Group.

* Responsible for cost effective designs which allowed the new Maryvale No 5 machine to be started within the existing mill site discharge licence constraints and water treatment capacities while satisfying internal stream quality requirements.

* Developed steady-state simulations of the water systems to allow prediction of environmental effects. Initiated development of high-fidelity models from Amcor’s Research & Technology Centre and from engineering contractors.

* Working with Water Reduction Task Force and having established several professional focus groups, delivered phased development opportunities to allow mill to reduce effluent volumes and contaminant quantities.

September 1995 - May 1996 Manager Technology Development, Amcor Paper Group’s International Division on special assignments at McKinley Paper Company, Prewitt, New Mexico and Holfelder Papierfabrik, Wiesloch, Germany.

* Coordinated water process optimization phase at Prewitt and performed commercial evaluation of system to allow future designs for other proposed mills.

* Co-authored study on integrated design of closed water systems into recycling mill operation.

* Established QA computer systems; designed and equipped quality control laboratory for Wiesloch mill; and set up environmental performance monitoring computer systems.

September 1993 - August 1995 Technical Manager McKinley Paper Company’s Prewitt, New Mexico Recycling Mill, reporting to Vice-President, Operations.

* Co-designed, using modeling techniques, mill closed water system, now patented worldwide as the Amcor Zero Liquid Effluent system.

* Supervised construction completion and commissioning of the Zero Liquid Effluent closed water system.

* In collaboration with mill’s chemical vendors, designed and specified chemical systems to suit totally-closed system. The system we pioneered with Betz Paperchem became the system of choice in tightly-closed mills.

* Participated in recruiting team and training of operators in technical aspects of paper manufacture and water system control.

* Participated in startup/commissioning of paper machine, responsible for product quality assurance and process control improvements.

* Established mill’s laboratories and quality assurance system, including purchase and implementation of QA software.

* Developed and implemented mill’s Environmental Management Plan.
