During the epidemic of the coronavirus covid-19 single-use plastic containing products were in high demand across the community and may not be cost effective to recycle. However repurposing such materials can reduce their environmental impact for instance plastic foam waste can be made into pots for planting different types of plants and trees. By mixing the foam with a suitable cement in a ratio of 1:1 a large range of pot diameters from 4.5-10 inches can be produced suitable for both indoor and outdoor planting requirements. These pot products suitable for growing plants of all sizes are durable unbreakable water tight. Therefore it is a product that repurposes the leftovers from the community and may even add value. This strategy helps reduce the problem of waste and in particular encourages replenishment of green space to nature and the environment which also helps to combat global warming.

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 research aimed to 1) To analyze the basic understanding and awareness of household waste separation. 2) To study the guidelines for the development of activities to raise awareness of waste separation in the household and 3) To practically benefit to raising social awareness from group activities. The sample used for this research was school students with education level lower than bachelor’s degree in Bangkok and vicinity. In-depth Interviews were used to collect data from 35 students. The research found that Attitude – According to comments from students during group activities they had the attitude towards the household waste separation at the highest level because the waste separation behavior reduces pollution and makes the environment cleaner. Personal Norm to follow all the survey questions was at a moderate level as 1) parents expected them to engage in waste separation behavior 2) friends expected them to engage in waste separation behavior and 3) friends placed importance on engaging in waste separation behavior. Perceived behavioral control to put into practice was at a high level due to 1) waste separation is easy and 2) being confident that waste can be separated on a regular basis. Intention – Students had a high level of intention to practice 1) Students were willing to separate the waste if there is an appropriate waste separation spot. 2) Students planned to separate the waste if appropriate waste separation spots are available. 3) Intended to separate their household waste on a regular basis. The results were used as a guideline for the development of activities activity development creating interest in activities. All of which were necessary to be environmentally focused and to lead to the storytelling to create continuity of activity. Recommendations – If possible the development of activities to raise awareness in the household for students and for parents should be integrated because parents have a significant influence in setting an example for target students.

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.

This research aims to develop the natural rubber and ethylene vinyl acetate (EVA) plastic floor tile with flame resistance property. The 6 ratios of natural-rubber STR 20: zinc oxide: stearic acid: sulfur: mercaptobenzothiazole: diphenyl guanidine: EVA plastic: antimony trioxide were equal to 100: 5: 2: 3: 0.5: 0.2: 20: 0 100: 5: 2: 3: 0.5: 0.2: 20: 20 100: 5: 2: 3: 0.5: 0.2: 20: 40 100: 5: 2: 3: 0.5: 0.2: 20: 60 100: 5: 2: 3: 0.5: 0.2: 20: 80 and 100: 5: 2: 3: 0.5: 0.2: 20: 100 by weight or phr. The samples are ground by two-roll mill and formed by compression molding at 150 degree Celsius with 30x30x0.2 cm of dimension for 4: 29 to 5: 19 minutes. The properties of the natural-rubber floor tiles were tested under ASTM standard. From the results it was found that the natural rubber and ethylene vinyl acetate plastic floor tile with flame resistance property was the suitable ratio for using as the rubber floor tiles in building and extinguished a fire by themselves. The antimony trioxide effected to increase the density hardness and thermal conductivity and decrease the tensile strength tear strength and wear resistance properties of the natural rubber and EVA plastic floor tiles
