Introduction: Sorting Waste Is Saving the Future
If you’ve ever thrown banana peels, plastic bottles, and used diapers into the same trash bin—you’re not alone. In most Kenyan households, waste is not separated. Everything is bundled together and discarded without much thought. But here’s the truth: mixed waste is wasted opportunity.
Proper waste segregation—the process of sorting waste into distinct categories before disposal—is the first and most critical step in sustainable waste management. It’s how we reduce pollution, improve recycling, cut landfill volumes, and protect both people and the environment.
In this post, we’ll explore what waste segregation is, the major types of waste, and give you an in-depth, Kenyan-relevant list of everyday items that fall into each waste stream. By the end, you’ll be ready to sort waste like a pro—at home, work, school, or business.
What Is Waste Segregation?
Waste segregation is the practice of dividing waste into different categories based on its type, composition, and disposal method. In most zero waste systems—including Kenya’s Sustainable Waste Management Act (2022)—waste is typically separated into at least three main streams:
- Biodegradable/Organic Waste
- Recyclable Waste
- Residual/General Waste
Some systems also include special categories like hazardous waste, e-waste, and medical waste for proper handling.
Why Segregation Matters in Kenya
Waste segregation isn’t just a “nice-to-have”—in Kenya, it’s now the law. The SWM Act mandates that all citizens and businesses separate their waste at the source. Here’s why this matters:
- Environmental Protection: Recyclables and compostables can be reused; when mixed, they’re often contaminated and sent to landfills or incinerated.
- Health & Safety: Proper sorting reduces exposure to hazardous substances, especially for waste pickers and children.
- Economic Opportunities: Segregation fuels the circular economy, enabling recycling companies, compost producers, and artisans to turn waste into value.
- Reduced Landfill Pressure: With over 60% of Kenya’s waste being organic, composting it alone could cut landfill use by half.
The 6 Core Waste Categories in Kenya
Let’s break it down:
1. Organic/Biodegradable Waste
This is any waste that comes from plants, animals, or food and can decompose naturally without harming the environment. In Kenya, this is the largest waste stream—making up over 60% of household waste.
Common Organic Wastes in Kenya:
- Ugali scraps, sukuma wiki stems, vegetable peels
- Fruits (banana, mango, avocado skins and seeds)
- Leftover food and bones
- Maize cobs, sugarcane peel
- Tea leaves and coffee grounds
- Grass cuttings, leaves, small branches
- Eggshells, coconut husks
- Paper towels, napkins (unbleached and food-soiled)
- Manure from small-scale livestock or poultry
- Spoiled or expired food from kiosks and markets
👉 Disposal method: Composting (home or community compost bins)
2. Recyclable Waste
Recyclables are materials that can be processed and reused to make new products. When sorted correctly, these items are valuable for businesses and waste pickers.
Recyclables Common in Kenya:
- Plastic bottles (soda, water, juice)
- Jerricans and yogurt containers
- Aluminum cans (soda, beer)
- Cardboard boxes (e.g., Unga packages, cereal boxes)
- Glass bottles (soda, beer, juice, jam jars)
- Scrap metal (wires, nails, iron sheets)
- Office paper and newspapers
- Hard plastics (e.g., buckets, chairs)
- Fabric offcuts (in small quantities)
- Tetra Pak cartons (milk, juice)
- E-waste (old phones, cables, remotes — requires special handling)
👉 Disposal method: Rinse, dry, and deliver to a recycling center or partner with a local waste collector
3. Residual Waste / General Trash
This category includes waste that cannot be reused, composted, or recycled. It’s the least desirable stream and should be kept as small as possible.
Typical Residual Wastes in Kenya:
- Diapers and sanitary towels
- Used tissues and cotton pads
- Cigarette butts
- Vacuum dust
- Razor blades
- Hair and nail clippings
- Masking tape
- Certain food wrappers with metallic lining
- Chewing gum
- Broken ceramics and mirror shards
👉 Disposal method: Wrap carefully (especially sharp items) and dispose through county collection or certified waste companies
4. Hazardous Waste
These are materials that pose health or environmental risks when not handled properly. They can be toxic, corrosive, flammable, or reactive.
Examples from Kenyan Homes and Businesses:
- Batteries (AA, phone batteries)
- Old paint cans
- Pesticides and herbicides (used in farms)
- Mosquito coil ash
- Expired medications
- Cleaning agents (bleach, ammonia)
- Nail polish, polish remover
- Fluorescent tubes and old bulbs
👉 Disposal method: Never mix with regular waste. Drop off at designated hazardous waste centers or contact county environmental offices.
5. Electronic Waste (E-waste)
With rising tech use in Kenya, e-waste is a growing problem. It includes gadgets that are broken, outdated, or no longer used.
Common E-waste in Kenya:
- Broken mobile phones and chargers
- Radios and TVs
- Laptops, monitors
- Keyboards, mice
- Printers and cartridges
- Remote controls
- USB drives and hard drives
👉 Disposal method: Partner with e-waste companies like WEEE Centre or Enviroserve. Never dump in general bins—it leaches toxic chemicals into the environment.
6. Medical Waste (Domestic-Level)
This is relevant for homes with chronically ill individuals, caregivers, or home nurses.
Examples:
- Used syringes and needles (sharps)
- Bandages and gauze
- Medication wrappers
- Gloves and masks
- Inhalers
👉 Disposal method: Place in a sharps container or sealed box and deliver to your nearest hospital or health center with proper disposal facilities.
Waste Segregation Setup for a Kenyan Home
Segregating waste doesn’t need fancy equipment. You can begin with:
- A bucket or compost pit for organic waste
- A sack or bin for recyclables (clean and dry)
- A black bag or small bin for general waste
- A separate small container for hazardous or electronic waste
Labeling each container and placing them in convenient areas (like kitchen corners or balconies) makes the system easier to follow for everyone in the household.
Educating Your Household or Business
Whether you’re in a flat, estate, school, restaurant, or office, creating a culture of segregation starts with awareness:
- Hold weekly awareness sessions at schools or churches
- Create clear, visual signage above bins
- Encourage kids to lead sorting as a fun responsibility
- Post sorting guides in shared spaces
You can also engage with community groups, SACCOs, and zero waste organizations for training and support.
Where to Take Sorted Waste in Kenya
Depending on your location, here are options for getting sorted waste to the right place:
- Recyclables: Partner with local waste pickers or SACCOs like Mr. Green Africa, TakaTaka Solutions, or Ecocycle
- Compostables: Use in home gardens or donate to organic farms and school gardens
- Hazardous/E-waste: Contact WEEE Centre, county environment departments, or NGOs involved in safe waste disposal
If you’re not sure where to take your waste, Zero Waste Kenya is compiling a nationwide waste map to help connect communities with the right partners.
Final Thoughts
Waste segregation isn’t just a technical task—it’s a transformational habit. Every time you choose to sort your waste correctly, you’re reducing pollution, protecting health, and creating value from what many people throw away.
It’s not about being perfect. It’s about being aware, intentional, and responsible.
The next time you go to toss out something, ask yourself:
“Can this be reused, recycled, or composted?”
That question is where the change begins.
