ถุงดูดซับธรรมชาติจากกากกาแฟหมักด้วยน้ำคีเฟอร์เพื่อดูดซับคราบน้ำมันปนเปื้อน
Oil spills in every household caused by cooking are difficult to eliminate when accumulating for a long time. In this study the researchers aimed to develop the remaining coffee grounds for oil absorption. From 2 coffee ground samples types A and B obtained from different coffee shop & coffee grounds type A demonstrated more effective in absorbing vegetable oil. The sample A was thus treated with hydrogen peroxide (H2O2) solution at the concentration of 0.5 1 3 33 50 80 and 100 percentages for 30 minutes and determined for the efficiency in oil elimination. The sample with at least 80 % (v/v) H2O2 showed the most effectiveness in absorbing oil. The coffee grounds that were later treated with pineapple juice fermented Kefir could help increase coffee ground degradation at 51.07 percentages. The Kefir treated coffee grounds packed in an absorbent bag revealed higher effectiveness in oil absorption at least 51.07 percentages compared to the controls that were cotton bag and coffee a harboring at the percentages of 73.85 and 30.04 respectively. This coffee ground bag after thrown into the ground could be decomposed in nature for 52 percentages within 1 month. Due to the oil elimination properties of the coffee grounds that are environmentally and human friendly as well as low cost it is possible to develop the kefir treated coffee grounds for being oil-absorbing products that can come in contact with human skin.

The objective is to produce the biomass pellet fuel from coffee silverskin and spent of coffee grounds. To study the percentage of cassava powder as binder was mixed at 5 10 15 and 20% by weight and the best condition was chosen. Then to study the ratio of coffee silverskin and spent of coffee grounds was 5 ratios (100 : 0 75 : 25 50 : 50 25 : 75 and 0 : 100) on propertied of biomass pellet fuel. Characteristics and properties of raw materials and biomass pellet fuel were analyzed. The results found that the highest property of the biomass pellet fuel was 20% of cassava powder as binder. The biomass pellet from spent coffee grounds as main component was higher quality than coffee silverskin. The biomass pellet from spent coffee grounds was the maximum fuel property. The bulk density was 0.9699 0.0045 g/ cubic cm shatter index was 92.6510 ± 0.2102% heating value was 17.2772 ± 0.0319 MJ/kg and heat utilization efficiency was 16.59 ± 0.02%. The results from the part of coffee silverskin and spent of coffee grounds ratio showed that the best ratio from 2 raw materials was 25 : 75 that gave the highest quality. The heating value was 17.1544 ± 0.017 MJ/kg and heat utilization efficiency was 16.48 ± 0.01%. In addition the study also discovered that the biomass pellet had moisture contents in the levels acceptable under biomass standards. Thus in summary the coffee silverskin and spent coffee grounds had physical property and fuel property according to the standardization to be made into biomass pellet fuel. It considered to be one of alternative fuels in country permanently.
ศึกษากระบวนการทำเครื่องปั้นดินเผาโดยใช้ประโยชน์จากกากกาแฟเหลือทิ้งเพื่อพัฒนาสู่การออกแบบเชิงสร้างสรรค์
The research objective of this research 1) study and experiment the waste of coffee waste to create a creative advantage 2) study and design pottery handicraft products using the waste of waste coffee material 3) develop and build on existing local knowledge that is valuable and worth a lot more Research results conclude that the trial in removing waste coffee residue as a clay mixture can make the product more beautiful in terms of texture and color tone. Which is very beautiful and has a higher value. Which when burned in the ideal temperature. The surface of the pottery will have a rough texture uneven and color in the color tone Din. Can develop into creative design. The design of pottery and handicraft products using the waste of coffee residue into creative design. The concept of design is to take into account the uniqueness of endowment beauty usability. Manufacturing Processes The design pattern is derived from three forms from which the researcher attaches importance to shaping the design of the pottery. The shape of the design is derived from the uniqueness of Thailand. The result of the design is a decorative sculpture home size is appropriate to the home decoration of all types all the beauty resulting from the local wisdom. Production experiments showed that It is a way to add value to your product.
การพัฒนาแผ่นซีเมนต์บอร์ดด้วยกากกาแฟเพื่อการอนุรักษ์สิ่งแวดล้อม
The using of ground coffee wastes from industries to develop the cement board is an objective of this research that can solve the air pollution problems from smell and spreading of ground coffee wastes. The ratio of Portland cement type1: fine sand: tap water is equal to 1: 0.5: 0.416 by weight and the ratios of Portland cement type1: ground coffee wastes include 1: 0.05 1: 0.06 1: 0.07 1: 0.08 1:0.09 and 1: 0.10 by weight (6 ratios). The production of cement board uses the pressure casting in temperature 30 – 35 degree of Celsius and controls 0.75 g/cm3 of density. The testing of cement-bonded fiberboard properties follow the TIS 878-2537 standard (cement bonded particle board: high density). From the results 1: 0.05 is the most suitable quantity of cement: ground coffee wastes which mixed in cement board. This cement boards can reduce the ground coffee wastes by using as aggregate to produce the construction materials.
