Consider a household that generates a certain amount of waste per day. Of this amount, bottles and cans represent 20 percent (by weight) and are recycled by the family. Twenty percent of the paper waste (32 percent total) is burned in the fireplace. The remaining paper along with the rest of the waste is put into containers for collection. On a given day, 20 lb of consumer goods (food, newspapers, magazines, etc.) are bought into the house. The family consumes 7 lb of food that day, and 5 lb of food is stored. The magazine received represent 5 percent of the paper wastes of the day, and they are not thrown away. Draw a materials flow diagram of this problem and calculate the amount of solid wastes disposed of during this day.
