Solid waste that are generated must be segregated as dry waste and wet waste. This would help in better treatment and disposal of waste.

In solid waste management, the two primary methods of collection are typically categorized as house-to-house collection and community bin collection.

Solid waste management encompasses the entire process of collecting, treating, and disposing of waste. Among the choices, disposal is the most comprehensive term for the final management stage.

Incineration has a relatively high initial cost because it requires specialized high-temperature furnaces, pollution control systems, and ongoing maintenance. Landfilling and composting are generally less capital-intensive options.

Combustible materials, including rubbish and animal remains, are typically incinerated (burnt) to reduce volume and eliminate pathogens. While they can be landfilled, burning is the standard management practice for combustible waste.

Composting is most suitable for Indian conditions because it's low-cost, environmentally friendly, and produces useful fertilizer. India's climate supports rapid aerobic composting, and it handles the high organic content in Indian waste.

Polyblend is a fine powder of recycled modified plastic. The binding property of plastic makes the road last longer besides giving strength to withstand more loads when mixed with bitumen. Polyblend lowers moisture absorption capacity due to the coating of plastics at the surface.
