In India, the most intuitive environmental problem is not solid waste, but India's problem of solid waste is not traditional industrial waste, but rather household waste.

When Chinese cities talk about the potential threat of a "landfill", many Indian cities are already enveloped in garbage.

Nowhere is the rubbish piled up in the streets, even in connaught square, in the heart of the capital, new Delhi.

According to an estimate by the organisation for economic co-operation and development (OECD), about 40 per cent of India's household waste is left unfocused, and is thrown away, creating environmental problems.

In fact, the problem of solid waste is not prominent in traditional India, because most of the former modern life garbage can be degraded rapidly to increase soil fertility.

However, with the continuous application of modern materials such as plastic, electronic products, India is way of garbage disposal at the advanced level - don't say that before modern classification recycling, even the most basic concentration of landfill and incineration in India cannot be completely.

It is not difficult to enjoy the technological achievements of modern society, but it is not easy to deal with the drawbacks of these technological achievements, which is also the crux of India's solid waste problem.
