- Biorefineries - Approximately every 30 years, the First World War, the Second World War, the Oil crisis of the 1970s, and now, interest in developing biorefineries from lignocellulose peaks. Research scientists at the Forest Products Lab advanced biorefinery technology during the 1940s and 1970s. We are continuing in this tradition by trialing several biorefinery concepts on the pilot scale. The engineering data from our trials are incorporated into economic models that allow use to evaluate the probability of success for biorefineries connected to a paper mill. We are also currently working with several paper companies in an effort to evaluate opportunities for biorefineries at particular mills.
- PSAs - Pressure sensitive adhesives are used in everything from shipping containers to postage stamps. We are reducing the negative environmental impact of PSA use by developing recycling compatible adhesives that are made from renewable materials. Beginning with sponsorship by the US Postal Service, we developed testing methods to determine if an adhesive is likely to cause problems in a paper recycling mill. Working with adhesive suppliers we have assisted in the development of PSAs that pass our test methods. We now are incorporating non-petrochemical monomers into new PSA formulations that will allow them to be biodegraded.
- Fungus - Fungi orchestrate a complex set of enzymes to degrade lignocellulose. In many cases the transformations caused by the fungi are similar to unit operation required for biorefineries. We probe the detailed mechanism of fungal action using the methods of polymer science, chemical analysis, and reaction engineering.
- Integrate biorefineries into pulp mill operations
- Estimate economic performance of various lignocellulose processes
- Understand the mechanisms of fungal decay using engineering analysis
- Develop recycling-compatible and sustainable pressure sensitive adhesives

|How Does Wood Decay Start?|
How do fungi rot wood? Using new tools, fluorescent dye attached to tiny beads, and laser confocal microscopy, Forest Service scientists were able to follow oxidation on a microscopic level. The information is helping them zero-in on the chemicals fu ...

|Scientists Determine Critical Factors that Caused Peroxide Explosion in Paper Mill|
In 2001, a peroxide bleach stage at a paper mill in Evadale, Texas, exploded, rupturing two bleaching towers, destroying a pump, and propelling fragments over 800 yards in all directions. There were no fatalities in this incident, but unfortunately, ...

|Recyclable, Compostable Stamps That Last “Forever”|
Do you remember the last time you licked a stamp? Maybe not, and for good reason: 20 years have passed since the U.S. Postal Service (USPS) first started transitioning from “lickable” stamps to the peel-and-stick squares we use today, called “pressure-sensitive adhesive” stamps by those in t...
