Solid waste management is the process of collecting, treating, and disposing of waste in a safe and environmentally responsible manner. It involves the planning, organization, and implementation of waste management programs to reduce the impact of waste on human health and the environment. 

The principles of solid waste management include:
Reduce and minimize waste
Re-use and repair
Recycle or compost waste
Energy recovery
Waste disposal (landfill, burial) 

Some methods of solid waste management include:

Recycling: Recycling is the conversion of waste materials into new products. Examples include wood recycling, paper recycling, and glass recycling.
Composting: Composting is the natural process of recycling organic matter, such as leaves and food scraps, into a valuable fertilizer that can enrich soil and plants.
Incineration: Incineration is a waste treatment process that involves the combustion of substances contained in waste materials.
