| + | of CDC (Center for Disease Control), we made contact with Mrs. Liu Yee Fen, the |
| + | contact person of Center for Occupational safety and Health and Environmental |
| + | Protection, which is the authorized unit in our campus responsible for lab |
| + | safety and security. With the assistance of our instructor Dr. Ng, we |

| + | some lab security instructions and advice. She also suggested that each of our |

| + | In our applied design, we planned to extract protein and bioproduct from E. coli . |
| + | The waste should be then collected and stertilized. We planned to combine the waste |
| + | heat recovery system in the factory to stertilize the waste medium . One of the |
| + | main goal of our applied design, to turn waste to valuable resource, is fulfilled |
| + | in this biosafety design. |
