Types of Solid Waste. Recycling is when waste is converted into something useful. It reduces the amount of waste that needs to be treated, the cost of its handling, its disposal to landfills and environmental impacts. It also reduces the amount of energy required to produce new products and thus helps conserve natural resources. Upcycling and downcycling are two common words used when it comes to recycling. Upcycling implies upgrading of a commodity by different processes of recycling.

An example of upcycling is to make roads out of cheap plastic. Downcycling implies downgrading a commodity by different processes of recycling. An example of downcycling is breaking down of high quality plastics at high temperature into different lower quality plastics. There are a large set of informal waste collectors in India. They are called local waste dealers or 'Kabadiwallahs'.

They collect and sort dry waste into aluminium, plastic, paper, glass, etc. Each waste has a price fixed in the waste market.

In addition to the waste pickers, the dealers also collect dry waste from individuals, apartments and institutions.

Municipal laws governing the urban local bodies do not have adequate provisions to deal effectively with the ever- growing problem of solid waste management. With rapid urbanization, the situation is becoming critical. The urban population has grown fivefold in the last six decades with The improper disposal of municipal waste has a serious and dangerous impact on a wide range of areas.

Garbage thrown in the street or in open spaces creates a public health hazard, while waste dumped near rivers, lakes and streams contaminates the water supply. Rubbish that is burned in the open rather than disposed of properly creates pollution and releases toxic fumes into the environment.

Non- biodegradable materials thrown into open drains make their way into the sewerage system, clogging pipelines and damaging infrastructure. The hazards posed by the dumping of untreated hospital and industrial waste are even greater, with the release of pathogens and toxic compounds posing a grave threat not just to human life but also to plants and animals.

Garbage dumped in the countryside is not simply an eyesore; entire landscapes are ruined and unique habitats for flora and fauna are lost. All of these problems are common in India, where vast quantities of solid waste remain uncollected in the streets, along major roads, in empty plots of land, down hill slopes and in illegal dumps.

Composting is the decomposition of organic matter by microorganism in warm, moist, aerobic and anaerobic environment. Farmers have been using compost made out of cow dung and other agro-waste.
