Summary: Particleboard is a wood-based panel product created raw under pressure and temperature using wood particles assessed with adhesives. In recent years, the need for wood in the Philippines has expanded dramatically, requiring imports from other countries. Technological advancements have made it possible to employ raw waste materials as an alternative to wood-based products. Coffee husk is the dried outer layer of the coffee fruit that remains after extraction, and it is a significant source of agricultural waste in the Philippines. Plastic waste, in addition to agro waste, is large across the country, particularly polypropylene plastics, which are extensively used in consumer containers. This study investigated the effectiveness of Coffee Husk and Polypropylene as Raw Materials and Isocyanate as a binder in Particleboard. The prototypes were manufactured using 5 mix designs as 44:45:11, 41:50:9, 38:55:7, 35:60:5, and 32:65:3. Each mix design is replicated 3 times with the dimension of 40cm x 40cm x 1.2cm and a target density of 0.8g/cc. The board was tested through Density Variation (DV), Moisture Content (MC), Thickness Swelling (TS) Test, Moisture Resistance (MR) Test, Density Variation, Moisture Content (MC), Modulus of Rupture (MOR), and Internal Bond (IB) Strength. The mix design 5 had the most successful test results in Density Variation, Moisture Content, Thickness Swelling, and Internal Bond Strength, as none of the boards passed Modulus of Rupture and Moisture Resistance. The product was then evaluated using the TUP Evaluation Instrument for Developed Prototype.

Particleboard is a wood-based panel product created raw under pressure and temperature
using wood particles assessed with adhesives. In recent years, the need for wood in the
Philippines has expanded dramatically, requiring imports from other countries.
Technological advancements have made it possible to employ raw waste materials as an
alternative to wood-based products. Coffee husk is the dried outer layer of the coffee fruit
that remains after extraction, and it is a significant source of agricultural waste in the
Philippines. Plastic waste, in addition to agro waste, is large across the country, particularly
polypropylene plastics, which are extensively used in consumer containers. This study
investigated the effectiveness of Coffee Husk and Polypropylene as Raw Materials and
Isocyanate as a binder in Particleboard. The prototypes were manufactured using 5 mix
designs as 44:45:11, 41:50:9, 38:55:7, 35:60:5, and 32:65:3. Each mix design is replicated
3 times with the dimension of 40cm x 40cm x 1.2cm and a target density of 0.8g/cc. The
board was tested through Density Variation (DV), Moisture Content (MC), Thickness
Swelling (TS) Test, Moisture Resistance (MR) Test, Density Variation, Moisture Content
(MC), Modulus of Rupture (MOR), and Internal Bond (IB) Strength. The mix design 5 had
the most successful test results in Density Variation, Moisture Content, Thickness
Swelling, and Internal Bond Strength, as none of the boards passed Modulus of Rupture
and Moisture Resistance. The product was then evaluated using the TUP Evaluation
Instrument for Developed Prototype.
