Abstract
This report summarizes the work and findings of a national research project designed to investigate both the process parameters that affect resin application efficiency and the possibilities for optimizing MDF resin injection systems. The scope of this research includes: developing and evaluating methods to quantify resin distribution, degree of resin pre-cure, and resin loss; conducting a series of experimental works using selected test methods to quantify the resin distribution of blowline-blended fibre, resin loss, resin pre-cure, and their correlations to MDF panel properties. Based on experiment results, the following conclusions can be reached:
Blowline resin injection is still the most effective and economical method for resin blending in MDF production.
Blowline resin blending efficiency is affected by fibre characteristics, resin distribution, resin pre-cure, and resin loss during the MDF process.
Resin distribution is affected by steam/fibre flow dynamics and consistency, and resin spray characteristics.
The best resin distribution can be achieved with steady steam/fibre flow at an adequate velocity (approx. 80 m/s at the injection point with steam pressure of 4.5 bar) and high turbulence in the blowline, low resin viscosity, and a good injection nozzle system.
Both the XRF test method developed by Forintek and the nitrogen content test using the Kjeldahl method are effective methods for determining resin content and resin distribution on the MDF fibre.
For the typical MDF mill studied, resin loss during the MDF process is about 6.5%.
Overall resin pre-cure in a typical MDF process is about 20%. Results from the laboratory experiment confirm that at 40ºC, the rate and magnitude of resin curing reaction can be significant.
The test methods developed or adopted in this study for analyzing resin distribution, resin loss, and resin pre-cure, and the computer model for calculating refining energy balance can be effective tools for optimizing blowline resin injection systems in MDF mills.

Abstract
This energy use status report focuses on five commodity products produced within the broadly defined wood products sector: softwood lumber, softwood plywood, oriented strand board, particleboard and medium density fibreboard. The study examines gross facility manufacturing energy use and puts this energy use in context by relating it to upstream energy required to procure raw material and energy inputs. In addition, this work tracks both direct and indirect carbon emissions by fuel type and accounts for the carbon sequestered in wood products and thus, presents a carbon balance for each finished product at the plant gate. Using a life cycle analysis approach, this report documents the cradle-to-gate energy use in the production of the five commodities. Data reported here can assist each industry segment in better understanding material and energy use for the purpose of reducing energy consumption in the future.

Abstract
Canada’s wood products industry has long played an important role in the Canadian economy. It is a diverse industry, producing both commodity and value-added products in every region of the country. This energy use status report focuses on five commodities produced within the broadly defined wood products sector: softwood lumber, softwood plywood, oriented strand board (OSB), particleboard (PB) and medium density fibreboard (MDF). The study, conducted by FPInnovations – Forintek Division, takes a different approach than other Canadian Industry Program for Energy Conservation (CIPEC) reports. It does not focus solely on gross facility manufacturing energy use, but also puts this energy use in context by relating it to upstream energy required to procure raw material and energy inputs. In addition, the study tracks direct and indirect greenhouse gas (GHG) emissions by fuel type and accounts for the carbon sequestered in wood products and thus, presents a carbon balance for each finished product at the plant gate. Using a life-cycle analysis approach, this report documents the cradle-to-gate energy use in the production of the five commodities, so each industry segment can better appreciate how it draws upon and uses materials and energy resources and how it may reduce its energy use in the future.
Chapters include resource extration, forest managemetn, resource transportation, softwood lumber manufacture, softwood plywood manufacture, oriented strand board manufacture, composite panel board manufacture, gross energy and carbon balance summary and energy use reduction potential in wood product manufacturing.
