Managing waste responsibly isn’t just good hygiene—it’s the law. Whether you’re overseeing a hospital, managing a construction site, or running a household, knowing which color-coded wheelie bin to use can significantly reduce cross-contamination, enhance recycling, and promote environmental sustainability.

In Kenya, organizations like NEMA (National Environment Management Authority) and global standards such as OSHA encourage proper waste sorting using color-coded bins. This guide by Kejani Cleaning Services Limited breaks down what each wheelie bin color means and the types of waste suitable for each.
