When it comes to waste management, not all garbage bags are created equal. The color of a garbage bag isn’t just a visual difference—it communicates the type of waste it holds, ensures safety, supports recycling efforts, and helps maintain sanitation standards, especially in commercial, industrial, and healthcare settings.

At Kejani Cleaning Services Limited, we supply high-quality garbage bags in various sizes and colors—each tailored to a specific purpose. Whether you’re running a hospital, hotel, office, or construction site in Kenya, understanding these colors will help you manage waste responsibly and in compliance with industry standards.


1. Clear Garbage Bags

Purpose: Transparency in disposal.

Best for:

  • Office waste

  • Recyclables

  • General non-hazardous waste

  • Airport or high-security zones (contents must be visible)

Why Use Them:
Clear garbage bags allow for quick visual inspections of contents, making them ideal where security or recycling sorting is a priority.


2. Red Garbage Bags

Purpose: Medical or biohazard waste.

Best for:

  • Hospitals and clinics

  • Laboratories

  • Health centres

Why Use Them:
Red garbage bags are internationally recognized for disposing infectious and biohazardous waste, including contaminated gloves, swabs, dressings, and blood-soaked materials. Using red ensures this dangerous waste is handled and incinerated separately, protecting public health.


3. Black Garbage Bags

Purpose: General waste.

Best for:

  • Household trash

  • Office garbage

  • Non-infectious waste

Why Use Them:
Black waste bin liners are the most common and versatile. They’re best for regular trash that doesn’t require special handling. They’re opaque, concealing unsightly waste, and are suitable for homes, restaurants, and general business environments.


4. Yellow Garbage Bags

Purpose: Clinical and infectious waste, sometimes chemical waste.

Best for:

  • Hospitals and care homes

  • Quarantine zones

  • Used personal protective equipment (PPE)

Why Use Them:
Yellow waste bags are used for potentially infectious clinical waste that needs high-temperature incineration. This includes body fluids, disposable gowns, and used dressings that are not heavily blood-stained. They help prevent the spread of disease.


5. Purple Garbage Bags

Purpose: Cytotoxic or pharmaceutical waste.

Best for:

  • Oncology units

  • Chemotherapy wards

  • Pharmacies

Why Use Them:
Purple waste garbage bags also known as cytotoxic garbage bags are designated for cytotoxic or cytostatic waste such as expired chemotherapy drugs, syringes, and PPE exposed to these materials. These bags ensure safe incineration and prevent environmental contamination.
