Characteristics of Maha Sarakham University’s waste    

From the study, survey and analysis of solid waste components of Maha Sarakham University. By studying the physical characteristics of solid waste (Physical Characteristic) from studying and collecting data on the amount of waste from faculties/departments that occur per day within Maha Sarakham University. Shows the amount or proportion of each type of waste generated to lead to further management planning. According to a study from Maha Sarakham University, there are 4 types of waste: general waste, organic waste, recyclable waste, and hazardous waste. When considering the percentage of solid waste components of each type of Maha Sarakham University, it was found that general solid waste had the highest amount, averaging 70.70 percent, followed by recycled waste, organic waste, hazardous waste, averaging 25.5 percent, 3.30 percent, and 0.5 respectively

     If there is separation of recyclable waste and organic waste, it will be managed at the source.(Faculty/Department) will be able to reduce the amount of waste that is sent for disposal by 28.8%, including separating organic waste that is mixed in general waste (plastic bags), which will further reduce the amount of waste that is sent for disposal.
