Mixed waste is the most expensive waste there is. Once food scraps, plastic, paper and hazardous items share a bag, each of them loses value: wet waste contaminates recyclables, recyclables slow down composting, and the whole load usually ends up in a landfill or an open dump.
Source segregation, separating waste at the point where it is created, is the simplest and most effective fix. It costs very little, yet it decides whether the rest of the system can work at all.
The three-bin basics
- Wet (biodegradable) waste: food scraps, vegetable peels, tea leaves, garden trimmings.
- Dry waste: paper, cardboard, plastics, metal, glass and textiles, kept clean and dry.
- Domestic hazardous and sanitary waste: batteries, bulbs, medicines, diapers and sanitary products, wrapped and kept apart.
Why it matters for businesses
For hotels, hospitals, campuses, offices and apartment communities, segregation turns a disposal cost into a set of manageable streams. Wet waste can be composted or sent to biogas on site, clean dry waste can be sold to recyclers, and the small hazardous fraction can be handed to authorised handlers.
Many local bodies in India now require large generators to segregate and, where possible, process their own wet waste. Getting segregation right first makes compliance far easier.
Making it stick
- Colour-code bins and label them with pictures, not just words.
- Place bins where waste is actually produced: kitchens, pantries, wards, classrooms.
- Train housekeeping staff first. They are the last checkpoint before collection.
- Measure: weigh each stream weekly and share the numbers with the team.
Segregation is not a recycling activity. It is a habit, and habits are built by design, training and feedback.
