　　简介：
　　The focus of the Trajano Research Lab is to develop process technology for the production of chemicals from forest biomass that complements existing forest industry operations.  These developments will require fundamental knowledge to enable process scale-up and prove economic viability.  Dr. Trajano studies the fundamentals of recovering sugars from biomass and the catalytic conversion of those sugars into chemicals.  These biomass-derived chemicals are a sustainable alternative to traditional petrochemicals.  She also studies the recovery and purification of speciality compounds from biomass for use in fragrances, vitamins, and pharmaceuticals.  These technologies will renew the forestry industry, create jobs in nearby rural communities, and contribute to the low-carbon economy transformation. 
　　British Columbia’s pulp is some of the strongest in the world and commands a premium price in the global marketplace.  In partnership with Canfor Pulp Products, Dr. Trajano is exploring how to recover polysaccharides from wood waste to make a green paper strength additive to further enhance pulp performance.  The effects of feedstock, temperature and time on polysaccharide recovery from wood waste will be described.  The effects of adsorption of model polysaccharides and polysaccharides from wood waste on paper properties will be presented.
