A recycling program collects aluminum cans, plastic bottles, and glass jars. They collected 120 aluminum cans, 80 plastic bottles, and 50 glass jars. Each aluminum can weighs 15 grams, each plastic bottle weighs 25 grams, and each glass jar weighs 300 grams. Calculate the total weight of the collected items in kilograms.

A recycling program collects aluminum cans, plastic bottles, and glass jars. They collected 120 aluminum cans, 80 plastic bottles, and 50 glass jars. With each aluminum can weighing 15 grams, each plastic bottle 25 grams, and each glass jar 300 grams, the total weight adds up in a measurable way. This calculation reflects not just numbers, but the collective environmental impact of everyday waste. As communities nationwide focus more on sustainability, tracking waste collection at the item level reveals how small actions scale into meaningful change. The idea of quantifying recycling—Dwight collecting 120 cans, 80 bottles, and 50 jars—resonates with growing public interest in transparency about waste. In the U.S., increasing participation in recycling programs is tied to rising awareness of landfill reduction, circular economies, and carbon footprint reduction. People want to know how much material is recovered, and specifically how heavy it is in familiar units, like kilograms. This number bridges data and reality, making environmental efforts tangible. To calculate the total weight, begin by converting each item’s count into kilograms using their respective grams per unit. For aluminum cans: 120 cans multiplied by 15 grams equals 1,800 grams—equivalent to 1.8 kilograms. Plastic bottles contribute 80 × 25 = 2,000 grams, or 2.0 kilograms. Glass jars total 50 × 300 = 15,000 grams, or 15.0 kilograms. Adding these weighted totals: 1.8 + 2.0 + 15.0 equals 18.8 kilograms of collected material. For practical reference, this weight is roughly the equivalent of 6.5 adult aluminum cans by volume or about 37 average-sized water bottles, highlighting the substantial volume behind these numbers. This calculation supports not only public records but also program effectiveness. By tracking actual weight, cities and nonprofits assess collection efficiency and material value for recycling markets. For residents, understanding the weight reinforces the impact of their participation—each can, bottle, and jar contributes directly to resource recovery and energy savings.
