The objective of this research was to study the clay tile (CT) production using palm ash (PA), spent bleaching earth (SBE) and palm fiber (PF) as substitute materials. The effect of ingredients and PF length on CT qualities were investigated. The ingredient of clay: PA: SBE: PF used three proportions as following 58: 20: 20: 2, 56: 20: 20: 4, and 54: 20: 20: 6 (% by weight, wt). Each ingredient used the fiber length of 15 and 25 mm. The crystalline phase of raw materials was inspected. The CT after production were examined qualities as accorded with Thai industrial standard (TIS) in terms of water absorption, bulk density, acid corrosion and transverse breaking strength (TBS). Results showed that the clay tile qualities in terms of bulk density and acid corrosion were in the acceptable level as 1.45-1.65 g/cm3 and less than 0.03%, respectively. The water absorption quality was more than 6.5% and the TBS was below 600 N. Hence, this research also revealed that the all wastes (PA, SBE, PF) from palm oil industry can be used to produce the clay tile.

Size grading is one of important processes for producing the Robusta green coffee bean because it can increase the value of green coffee bean and decrease the problem in the manufacturing process, especially roasting process. Therefore, the objective of this work was to investigate the effects of inclined angle and oscillating revolution speed on the performance of size grading machine of Robusta green coffee bean using oscillating sieve with swing along width direction. When increasing the inclined angle from 4 to 6 degree, the weight purity index and the clogging sieve percentage were decreased. For the size grading efficiency, it found that the size grading efficiency was increased when the inclined angle increased from 4 to 5 degree. However, the size grading efficiency was decreased when increasing the inclined angle from 5 to 6 degree. When considering in term of oscillating revolution speed, the increase of oscillating revolution speed provided the decrease of weight purity index, size grading efficiency and clogging sieve percentage. The appropriate condition for using the size grading machine of Robusta green coffee bean using oscillating sieve with swing along width direction is the inclined angle of 5 degree and the oscillating revolution speed of 185 rpm.

One of the essential processes for producing the green coffee bean with Robusta variety is size sorting process because it is able to add the value of green coffee bean. The excellent size sorting can be done by using the size sorting machine. In this study, the size sorting machine with revolved sieve which provided the good distribution of green coffee bean was used and the three factors such as sorting angle, revolved speed and feed rate were investigated using Response Surface Methodology (RSM) based on a Central Composite Design (CCD). The optimum conditions of size sorting efficiency were revolved speed of 8.35 rpm, sorting angle of 5.05 degree and feed rate of 26.59 kg/h. These provided the size sorting efficiency of 75.15% with high correlating coefficient (R2 = 97.65). This indicated that the data predicted with Response Surface Methodology was good agreement and adequacy of models.

Bleaching earth (BE) and empty palm bunches (EPB) are residual materials in the palm oil production process. Inside BE consisted of copious oil quantities, in the same way, the EPB had the high heating value. These residual materials could be recycled to become the biomass briquettes (BB). Therefore, this work investigated the BB production at the different condition. The compression temperature was 150, 250 and 350°C. The compressive velocity was 30, 40 and 50 rpm. The mixture ratio by weight between BE and EPB was 30:70, 40:60, 50:50, 60:40 and 70:30. After production, the BB were examined the fuel properties, i.e., moisture content (MC), ash content (AC), the heating value (HV), the fixed carbon content (FC) and volatile matter content (VC). Experimental results showed the MC, HV, FC and VC diminished with the decrease of EPB quantity. The AC increased with the augmentation of BE content. The BB production rate increased with the compression velocity by it had the maximum production rate about 390 pieces per hour at the velocity of 50 rpm. Moreover, the increased velocity affected the diminution of HV, fixed carbon, moisture and volatile matter for some the mixture ratio and compression temperature. The alteration of compression temperature insignificantly affected the quantity of HV for some the mixture ratio and compression velocity. The BB production should be produced at the ratio of 30:70 combined with the compressive speed and temperature of 30 rpm and 250°C, respectively. This condition gave the high HV, the low moisture content corresponded with the standard of fuel properties, excepting, the quantity of ash and fixed carbon.

The environmental impact of synthetic leather production has raised global concerns due to its reliance on petroleum-based polymers and poor biodegradability. Therefore, the development of sustainable, eco-friendly alternatives using renewable resources has become increasingly important. A biodegradable vegan leather was developed from natural rubber and pineapple leaf fibers (PALF), with properties analyzed using Response Surface Methodology (RSM). The effects of fiber content (X1), compression time (X2), and compression temperature (X3) were studied on biodegradation (Y1), water absorption (Y2), and tensile strength (Y3). Results showed that all three factors significantly influenced Y1, with the predictive model demonstrating high reliability (R > 90%). The optimum condition for Y1 was X1 = 3.0 g, X2 = 70.0 min, and X3 = 110.0 C, yielding a maximum predicted biodegradation of about 21%. In contrast, the models for Y2 and Y3 were statistically unreliable (P > 0.05) due to low RÂ² values. However, Y2 passed the lack-of-fit test, suggesting an adequate model form, while Y3 failed (P < 0.05), indicating an inadequate prediction model. These findings suggest future experiments should narrow factor ranges and include additional control variables to improve the predictability of Y2 and Y3. Despite these limitations, the study highlights a sustainable alternative to conventional synthetic leather, aligning with circular economy principles and supporting the United Nations Sustainable Development Goals (SDGs). Importantly, the process is resource-efficient: from 1 kg of pineapple leaves, only 20 g of fibers is obtained, and just 75 g of PALF was used in 15 experimental runs. This minimal material requirement underscores the potential of the approach for sustainable production, while highlighting potential applications in sustainable fashion, packaging, and eco-friendly product design.

This research evaluated the effects of foam packaging on wholesale packages of banana (‘Kluay Lab Mue Nang’) in Chumphon province, Thailand. The experiment was divided into 3 experimental sets, namely, 1) foam net (FN); 2) expanded polyethylene foam (EPE); and 3) controlled sample without use packaging (NOP) and damages were categorized into three types which were bruising, abrasion and laceration. Vibration tests were performed following the standard method of ASTM D999 Method A2 using the frequency of 4 Hz for one hour. Results revealed that the total damage of EPE (bruising, abrasion, and laceration) was higher than that of FN. When considering the percentage of damage area, it was found that the damage percentages of EPE caused by bruising and abrasion were 7.41 and 3.28%, respectively, and the damage percentages of FN caused by bruising and abrasion were 5.73 and 3.82%, respectively. There was no damage from laceration detected. The results showed that FN had the greatest reduction in damage. The controlled sample (NOP) had a total damage of 20.79%.

The aim of this paper is to increase energy efficiency by reducing specific energy consumption (SEC) during Cissus quadrangularis drying. The fresh sample, with a high moisture content of 90 ± 2 % wet basis (w.b.), was dried by hot air Fluidized bed technique at temperatures of 90, 110, 130 and 150°C to a final moisture content of 5 % (w.b.) and then was compared to the results of tray drying at a low temperature of 50°C, following a method by Tha Sae Hospital in Chumphon province, Thailand. The drying kinetic result revealed that fluidization drying had a higher rate of water removal than the tray drying method. That rate directly correlated with the drying temperature; it increased with an increase of drying temperature. With the increasing of the rate, it resulted in a decreasing of SEC. Although using a drying temperature of 150°C had the highest rate of water removal and subsequently had the lowest SEC, it negatively affected the antioxidant activity of the sample. To dry Cissus quadrangularis with the lowest SEC as possible, it should be dried by hot air fluidization at a drying temperature of 110°C. At this drying condition, there is still a high rate of water removal and a low effect of the desired qualities of the sample.

The steaming process with revolved sieve was studied as a function of steaming time and revolution velocity. The quality of parboiled rice in terms of thermal property, head rice yield and color was investigated and compared to the conventional steaming process such as fixed sieve. The experimental results showed that the steaming process with revolved sieve had advantage over the steaming process with fixed sieve. It led to a steamed sample with higher DG higher head rice yield and lower whiteness value. The required steaming time for a regularity quality by a steaming process with revolved sieve was also shorter. Moreover, the steaming time affected the qualities of parboiled rice. The long steaming time provided the higher DG and head rice yield and lower whiteness value of parboiled rice. Considering revolution velocity, it was found that the revolution velocity did not affect the qualities of parboiled rice. However, the revolution velocity of 5 rpm with steaming time of 5 min provided the difference of quality at each layer.

Betel nut kernel is an important raw material in the leather and dye industries. The quality control after harvest is necessary, especially, the excess moisture content may cause the spoilage. Therefore, this research aims to study the betel nut fruit drying using infrared ray combined with the rotated trays. The betel nuts fruits were placed in rotated trays. These trays were installed within drying chamber which had the infrared rod in 2 positions namely the center and wall of drying chamber. The drying temperature used at 80, 100 and 120°C. The revolution speed of tray was set at 2, 4 and 6 rpm. The dried betel nut fruits were cut into 2 pieces at the blade speed of 25, 30 and 35 rpm. The experimental results showed the installation of infrared rods at the center could decrease the moisture content faster than at the wall. The betel nut fruit should use the drying temperature of 120°C for 10 h and the revolution speed of 2 rpm. The blade speed of 30 rpm gave the most cutting performance about 76%. The colour of dried betel nut kernel (L∗, a∗ and b∗) did not significantly difference with the commercial betel nut.
