In an average week, a family of five purchases and brings into their home 100 kg of consumer goods (e.g., food, magazines, newspapers, furniture, packaging material, junk mail). Of those 100 kg, 40 percent is consumed as food. Approximately 50% of that food is used for body maintenance and released as carbon dioxide; the remainder is discharged to the sewer system. Approximately 2 kg of consumer goods accumulate in the house. The family recycles approximately 30 percent of the solid waste generated (their state mandates a minimum of 25 percent). Estimate the amount of solid waste this family places at the curb each week for collection.
