Develop a prototype of the smart bin for supporting solid waste management at the source. The objective is to develop the functionality of the smart bin to meet the requirements of users. A body design of the smart bin prototype made from plastic with a lid size 25 cm. x 36 cm. x 48 cm. the total volume of the smart bin was 31.5 kg and using ARM STM32F4 series micro controller to control the functions of the smart bin. There is a sensor to measure the temperature and humidity. Ultrasonic level sensor Infrared distance measuring sensor and weight sensor with load cell data display controlling the opening and closing of the smart bin by servo motor. A Smart bin prototype can show the amount of waste. Moreover the level of waste and the weight of the waste inside were showed. The smart bin was showed relative temperature and humidity values inside a bin. The optimum distance to the reflective object of the sensor for opening and closing the smart bin was in the range of 20-50 cm. The Smart bin lid provided approximately 7-9 seconds to maintain the status to lid open representing an average time of 7.4±0.9 seconds. This research will help promote waste management at the source and effectively benefits to solve the problem of waste accumulation in place.

This project was created to sort bottles automatically. By specifying 3 types of bottles which are plastic bottles glass bottles and cans To help facilitate the separation of the bottles and then recycle the extracted bottles as needed. The organizer has studied the use of the Arduino program to control the operation of the sorting bottles according to the specified category. Studied the microcontroller system operation Control system And how to use the Arduino program The operating system is divided into 2 parts namely the metal detection sensor section And weight sensor and then send data to the sensor receiver Arduino And the sensor will detect the object all the time in the empty bottle compartment The results showed that the operation of the automatic bottle sorter system When throwing the bottle through the sensor compartment. The performance of the Arduino program that has been written to define the classification of the bottles. Have the percentage of work as specified by 90% and the error percentage of 10%

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 development of loincloth at Ang-Hin Chonburi Stone Basin is to study the pattern of hand-woven cloth and to develop hand-woven cloth products. The area of study cloth loincloth and products of cloth loom hand Chonburi to be developed into a bag product. The results showed that. The information will be used to develop the luggage bag product three patterns of plaid pattern were studied Include Nok Ka Ta pattern Sai Pla Lai pattern and square pattern. The unique colour of the weaving group for design the bag has been developed in a variety of styles and functionalities that can accommodate five types of adolescent behavior. From the focus on the use of working age to study the behavior of the use of existing luggage and increase the usefulness of the use of behavior all models are versatile. Both can be transported for tourism can be inserted. There is a selection of materials other than loincloth to create a variety of materials including sewing so that the parts of the bag are strong especially the ear piece which requires heavy weight and is often damaged before. The first Choosing colors in cool colors. The majority of the sample chose Include Nok Ka Ta pattern (42.5%); they answered that cool tone loincloth was the most suitable tone for producing bag product(65%); the design was the most important factor affecting the purchase decision(60%); the sample mostly used bag when they worked (70%); the useful life of each bag was 2-3 years ( 52.25%); the sample decided to purchase the new bag because the old one was damaged (45%); the most wanted item for the sample was tote bags (42.5%); the suitable material to produce the bag product was leather (61.25%).

It is well known that waste spoiled are undesired and one of the main causing of environmental problems and health effects. In Thailand there are growing wastes especially at Thewarat market every year. The causes of the increase in wastes are from economic and industrial expansion which are important issues for the community responsible to manage and correct the amount and types of waste disposed properly before disposal. In the study a preliminary survey by talk and providing the questionnaires were conducted at the Thewarat market. It was found that solid wastes or rubbishes are mostly generated during and after trading process with and without proper can disposal. The stores did commonly dump the solid and liquid wastes around the stores or nearby the bin not inside the bin. The unpleasant observations shown were the solid wastes and dirty water contaminating into the soil and in the waterway and it was not managed hygienically. Uncared by unconcerned sellers during busy market during the day more unrecognized attitudes of the merchants themselves inappropriate placement of food and food waste in the public for the buyers and manucipal wastes generated by people in the surrounding community were normally observed daily. More risks of disease spreading and accumulated rodents insects and pathogens breeding and homing were appeared during at night after the market closed. In the research the campaign and suggestions were operated by the research team the proposed strategies for the waste management at Thewarat market area were including two times of training; discussions and 2 leaflets. These sessions were based on the education on proper waste management highlight on the proper use of right trash bin with the right waste post-sales area management and the use of microorganisms for the production of bio-fertilizers and bio-fermented solution from biodegradable waste in the market community. Moreover the monitoring communities were done for the proper use of trash bin in the community and providing the right waste management. It could bring the benefits to the community at the initial level especially the realization and attitudes in the suitable waste management since approximated 10% shops keep their shops and area nearby clean thus adding a panoramic view with a good image to the Thewarat market.
