Abstract

The use of natural resources as particleboard materials has significantly increased due to growing environmental and sustainability concerns. This study aims to evaluate the physical and mechanical properties of particleboard made from three waste materials: eggshell particles, wood particles, and bamboo particles. The composite was formulated with the volume fractions of 10% epoxy resin, 25% Polyvinyl Acetate (PVAc) adhesive, 40% eggshell particles, and a 25% combined bamboo and wood particles. The bamboo-to-wood ratios investigated were 0:25 (B0W25), 12.5:12.5 (B12.5W12.5), and 25:0 (B25W0). Samples were prepared by cold compaction at 3 MPa for 2 hours, followed by curing at 100°C for 1 hour. The samples were evaluated for various physical properties, including density, water absorption, and thickness swelling, as well as mechanical properties such as hardness, flexural strength, flexural modulus, and flexural strain. Since multiple responses were obtained, the Data Envelopment Analysis-based Ranking (DEAR) method was used to assess composite performance. The study found that sample B25W0 exhibited the most optimal performance, with a density of 1.53 ± 0.01 g/cm³, water absorption of 8.47 ± 0.36%, thickness swelling of 6.05 ± 0.89%, hardness of 67.17 ± 0.94 Shore D, flexural strength of 12.90 ± 0.29 MPa, flexural modulus of 1.24 ± 0.03 GPa, and flexural strain of 2.23 ± 0.17%. The improvement is attributed to the alkali treatment of the bamboo particles. These results indicate that eggshell and bamboo hybrid fillers have strong potential as for structural particleboard.

Abstract

Heat exposure can influence the changes in hardness and flexural strength of composites made from eggshell particles and bamboo fibers. The composite samples were prepared through cold compaction at 5 MPa for 2 hours. The materials were combined based on the following volume fractions: 50% epoxy resin, 10% alumina, 10% graphite, 5% zinc oxide (ZnO), and a 25% mixture of eggshell particles and bamboo fibers. The composite samples were then heated to 200°C for 1 hour. The final step involved curing, which required heating the samples in an electric oven at 150°C for 1 hour. Using a weighting method, the composite containing 25% eggshell particles achieved the optimal result, with a multi response performance index (MRPI) of 42.43. This composite exhibited hardness, modulus of elasticity (MOE), modulus of rupture (MOR), and strain values of 70.24 Shore D, 37.65 MPa, 8.58 MPa, and 0.78%, respectively. Conversely, the sample with 25% bamboo fiber and no eggshell particles demonstrated the highest flexural strength at 12.06 MPa, while the sample containing 25% eggshell particles recorded the highest hardness of 70.24 Shore D.

Abstract

Aim: This study aims to determine the potency of horsetail plant to remove heavy metal concentration. Methodology and Results: Data was obtained from fifty-four (54) horsetails which were divided into three batches of 12, 18, and 24 plants respectively. Furthermore, the experimental method with the subsurface flow system treatment was used with two samplings for seven days. The results showed that the first, second and third batches gave a 6.83%, 10.28%, and 16.26% impact on reducing concentration of Fe respectively with an approximate average of 11%. Therefore, the detention time of the leachate constructed wetland reactors significantly reduced the Fe contaminant. Conclusion, significance, and impact of study: This research provides a solution to mitigate the environment by adopting the accumulator of Horsetail plants (Equisetem hyemale) in the constructed wetlands reactor experiment. From the three reactors approximately 0.03 mg/L of heavy metal iron was removed after a seven day run. Therefore, horsetail plant showed a positive impact in reducing environmental pollution, a trend adoptable in wastewater and leachate treatment technology in Indonesia.
