2. Objectives of field observation at Sai Mai transfer station To find the percentage of plastic wastes in municipal solid wastes To identify the types of plastics in municipal solid wastes 3. Procedures of sample collection The random sampling method is use to collect waste samples base on the American Society for Testing and Materials (ASTM). First, random spot are chosen and separated from the original waste using a shovel as shown in Figure C-44. Secondly, mix the pile of separated waste to get a heterogeneous sample than divide the waste into four different piles of waste as shown in Figure C-45. From the four different piles, 2 of it are eliminated while the other 2 are used for sample analysis as shown in Figure C-46. This is to ensure homogenous collection of waste. The wastes from each pile are then segregated according to the type of waste. After segregation, each type of wastes is measured with a weighing machine. Only plastic samples are separated into each type of plastics.

4. Categorizing of waste Waste from C-47 pile separated from the original pile of waste are segregated into papers, plastic and foams, glass, metals, textiles and organic waste are segregated, and then wastes are placed into plastic bags to identify the waste composition of the piles using a weighting scale as shown in Figure C-47.
