Prompt Description

1. Overall Layout: A centered circular closed loop, equally divided into four quadrants. Four segments are equidistantly distributed clockwise on the ring, connected by light blue arrows, forming a complete cycle. 2. Four Core Segments (clockwise): First Segment (12 o'clock position): Agricultural Waste Input Icon: A simple corn cob outline icon. Label: "Agricultural Waste" (e.g., corn cobs). Visual: The icon is filled with light green, symbolizing nature and raw materials. Second Segment (3 o'clock position): Biomanufacturing Core Icon: A combination icon of a flask and a double helix DNA, representing synthetic biology fermentation. Label: "L-Lactic Acid Production." Visual: The icon is filled with blue, symbolizing technology and manufacturing. Third Segment (6 o'clock position): Material Synthesis Icon: A polymer chain structure icon composed of "PLA" letters. Label: "PLA Synthesis." Visual: The icon is filled with dark blue, symbolizing materials and polymerization. Fourth Segment (9 o'clock position): End Products Icon: An outline icon of a degradable lunch box or shopping bag. Label: "Green End Products." Visual: The icon is filled with green, symbolizing environmental protection and finished products. 3. Connections and Dynamics: Each segment is connected by simple curved arrows, with the arrow color being light blue, indicating the direction of material and value flow. In the center of the ring, a circular arrow icon or the words "Green Material Ecology" can be added to highlight the theme. 4. Style and Color Scheme: Background: Pure white. Lines: All graphics use thin solid line borders, without shadows, maintaining a flat design. Color Scheme: Green (#4CAF50): Represents agriculture and environmental protection. Blue (#2196F3): Represents technology and manufacturing. Light Blue (#87CEEB): Used for connecting arrows. Font: Use a sans-serif font (such as Microsoft YaHei, Arial), with small and clear label text.
