-Sources of fiber and structural materials
-Medicinal and cosmetic products
-Extractive or chemical products
-Edible fruits and nuts
-Animals and animal-derived products
-Chemically-processed products
Current Status of Forest Products Research
Philippine total land area: 30 M ha
Forest cover: ~23% (lower than global avg. of 30%)
EO 26 NGP: Reforestation program
EO 23: Prohibiting timber harvesting in natural forests
Research Gaps
Insufficient quality planting materials
Lack of information on disease control technologies
Low productivity due to wood effects
Need for new technologies for value-added products
Limited satellite laboratories
Conflicting policies
Lack of livelihood programs and marketing systems
Production vs. Consumption
2020: Local supply of wood did not meet 6 million cubic meter consumption
Increased demand for construction, packaging, furniture, etc.
Decrease in exports, increase in imports → negative economic impact
Wood Properties & Forest Products Technologies
Properties: Physical, Mechanical, Chemical, Anatomical
Wood Modification: Enhances properties for service life
Thermal Modification: Reduces moisture absorption, improves stability
Mechanical Properties
Strength properties (bending, compression, tension)
Toughness: Energy absorbed during bending
Resilience: Resistance to bending
Chemical Properties
Proximate Chemical Analysis: Holocellulose, Alpha-Cellulose, Lignin, Extractives
Anatomical Properties
Sample preparation using a microtome
Image analysis using Optika microscope and ImageJ
