Micrometer scale optical measurements of paper caliper and refined fiber must be reconciled with the massive, energy-intensive machines they are intended to control. Although there are quite different measurement technology paths used by suppliers, all roads may lead to Rome from a control and quality management point of view.

Demonstration projects include nanocellulose and lignin production, with bio-fuel from wood waste to come. Bio-energy is also an important part of the portfolio.

Government of Ontario seed funding through CRIBE (Centre for Research and Innovation in the Bio-Economy) is promoting new bio-product and bio-energy projects which may help to turn around the province's forest products industry.

Tembec is one of a select group of companies in the world which have been refining wood chips into their constituents for years, producing specialty cellulose and by-product chemicals.

Supervisory optimization controls (APC) automatically coordinate the numerous steps involved in batch digester charging, cooking and blowing during steady state operation, during production rate changes and during fibre species changes.

Scanning measurements of fiber weight and moisture are now combined in a single infrared sensor. Nuclear material licensing, handling and staff training are eliminated.

Users of molded plastics are asking for alternate materials which are strong, durable, light in weight and made from renewable sources. A growing number of companies – including a Canadian one - are leading the way with wood pulp-based composites.

Advanced process control (APC) can deal with lengthy time delays and stabilize the kiln operation from shift to shift. Pulp mill bottlenecks have been solved and significant energy savings have been achieved.
