SB PulpDesign AB is a one person company with over 40 years of experience in the pulp & paper industry.
Experience
I, Staffan Berg, started the company in April 2020 to work as an independent consultant. My work experience has been built in a career spanning over 40 years in various positions in large Swedish forest products companies.
Kraft process, fibre lines, recovery, waste-water treatment and the interaction between the mill processes
I have extensive experience of all parts of a Kraft mill, but my areas of specialisation have been the fibre lines and the wastewater. I am uncommon in that I have experience of how the different parts of a mill interact. It is often forgotten that a truly optimised process should be tuned to improve the performance of future production steps in downstream sections of the mill. To summarise; I am more of an,” Interaction specialist,” when it is much more common to be a specialist in digesting, bleaching, recovery or wastewater treatment alone.
Mechanical pulp
I have a great degree of experience working with TMP, CTMP and HTCMP.
Process-simulation
My work with mill interactions from the wood yard to the paper/board machines and wastewater systems has given me a lot of experience in process simulation. In the past I worked with Win-Gems but for the last 15 years I have been working with the Extend-based ”PaperFront.”
From Fibre properties to Paper properties
My experience is not confined to the pulp mill. I have worked on how the properties of the fibres impact the stock preparation and the properties of the paper or board products produced. As a Product Development Engineer at the Iggesund mill I spent more than 10 years optimising the fibre production for optimal paper properties.
Waste water treatment
I have experience from design and operation of both biological treatement and chemical percipitation (inkluding biogas production) of waste water from Kraft- and mechanical pulping. The experiences resulted in a procedure to caracterize the organic content (COD/TOC). The result is used to predict the cleaning and gas production potential.
