本書從一個生活化的小插曲展開:小女孩 Tiana 追著跑向回收車的狗狗 Bubbles,也意外踏上一趟認識回收世界的旅程。跟著她走進資源回收場,孩子將看見紙張、塑膠、金屬與玻璃如何被分類、壓縮,再變成全新的物品。故事以輕快節奏串起清楚的知識說明,讓「回收之後發生了什麼事」不再抽象。適合親子共讀與課堂延伸,讓環保行動從日常開始。After their dog Bubbles chases after the recycling truck, Tiana and her family set off on a search to the Materials Recovery Facility, learning about recycling along the way. Exploring the MRF on their adventure, they see how papers, plastics, metals, and glass are collected, sorted, and baled, and then sent to be made into new products. Based on facts about the process of recycling in industrial countries, this book will help children understand the importance of recycling to save natural resources, as well as how they can take action in their own communities.
