Panel Board From Coconut Fibre And Pet Bottle

Abstract

The rate of global deforestation and its impact on the environment has led particle board manufacture to search for alternative feedstock, especially in countries where wood is less available compared to other cellulosic natural product. Based on the properties of coconut fibre and PET bottle, these two materials can be recycle as raw material for manufacture of panel board. As for this study, the coconut fibre were used as the filler and PET bottle as outer lining of the panel board. Two types of coconut fibre were used which are grinding and un-grinding coconut fibre. At first, the coconut fibre are undergoes softening, grinding, drying and sieving process, while PET bottle was cleaning, shredding, sieving before compacted using hydraulic hot press machine. There are four types of testing that been carried out which are swelling, water absorption, Modulus of Elasticity (MOE) and Modulus of Rupture (MOR). The result show the conventional board has the highest value for MOE test, so it’s indicate that the conventional board is less strength from the coconut fibre board. As for water absorption test, the average water absorption of coconut fibre based panel board is less than conventional board. Overall, the coconut fibre board is better than conventional panel board because coconut fibre board are less swelling, has low water absorption, high modulus of rupture and low modulus of elasticity. Based on the finding, this coconut fibre panel board has potential as a stronger and long-lasting panel board than the conventional board in the market. Other than that, the panel also have their own aesthetic value since the recycled plastic bottle used as outer lining is colourful and giving aesthetic value.

Recent Progress in the Application of Coconut and Palm Oil Fibres in Cement-Based Materials

“…In John et al [33], the fraction of hemicellulose was 11.6-21%, and those of cellulose and lignin were a maximum of 60% and 45%, respectively. According to John et al [33] and Ngadiman et al [35], the ash contents are approximately 2.2% to 8.1%. Cellulose seems to be the main component of coconut fibre.…”

Adhesive application on particleboard from natural fibers: A review

“…It also does not need any reinforcement from synthetic petroleum-based adhesives. 59 Lignin adhesive is characterized by low reactivity leading to long-pressing times and thus increased production cost in panel manufacturing. It is worth mentioning that a combination of tannin/ lignin to replace formaldehyde has also been reported in the literature.…”

“…Bio‐based adhesives are characterized by some common problems a lack of economically viable crosslinkers for bio‐based adhesives that would increase reactivity, mechanical properties, and humidity stability. It also does not need any reinforcement from synthetic petroleum‐based adhesives 59 . Lignin adhesive is characterized by low reactivity leading to long‐pressing times and thus increased production cost in panel manufacturing.…”
