Illustrative children’s book double-page spread, left page designed as three simple educational visual sections stacked vertically, clean background and pastel colors: top section: colored plastic pieces pouring into a chute, transforming into small bead-like granules below, a simple spiral pipe or small machine in the background; middle section: broken green glass pieces entering a hot furnace, orange melted glass flowing out below, next to a forming silhouette of a jar or cup; bottom section: crushed drink cans being compacted into solid rectangular metal blocks, stacked neatly; each process is shown clearly and minimally, with soft outlines and pastel tones (yellow-grey for plastic, green for glass, silver-grey for metal), no clutter, simple shapes, clean layout.
