What is Solid Waste Management
Solid waste management is a process of collecting, treating, and disposing of solid material that has been discarded after serving its purpose. Everyday, a huge amount of solid waste is been disposed from residential, commercial, and industrial areas. Solid waste management also offers solutions for recycling items for both garbage and non-garbage materials. Land filling sites using solid waste, can produce foul smell if the waste is not treated properly. It pollutes the surrounding air and can create serious pollution to our environment.
Types of Solid Waste
So here are different types of solid wastes that can be treated into producing necessary or non harmful materials.
Residential areas where people live are some of the major sources of solid waste. Garbage from these places include food wastes, plastics, paper, glass, leather, cardboard, metals, yard wastes, ashes and special wastes like bulky household items like electronics, tires, batteries, old mattresses and used oil. Most homes have garbage bins where they can throw away their solid wastes in and later the bin is emptied by a garbage collecting firm for treatment.
Industries are known to be one of the biggest contributors of solid waste. They include light and heavy manufacturing industries, construction sites, fabrication plants, canning plants, power and chemical plants. These industries produce solid waste in form of housekeeping wastes, food wastes, packaging wastes, ashes, construction and demolition materials, special wastes, medical wastes as well as other hazardous wastes.
Commercial facilities and buildings are yet another source of solid waste today. Commercial buildings and facilities in this case refer to hotels, markets, restaurants, go downs, stores and office buildings. Some of the solid wastes generated from these places include plastics, food wastes, metals, paper, glass, wood, cardboard materials, special wastes and other hazardous wastes.
Crop farms, orchards, dairies, vineyards and feedlots are also sources of solid wastes. Among the wastes they produce include agricultural wastes, spoiled food, pesticide containers and other hazardous materials.
Construction sites and demolition sites also contribute to the solid waste problem. Construction sites include new construction sites for buildings and roads, road repair sites, building renovation sites and building demolition sites. Some of the solid wastes produced in these places include steel materials, concrete, wood, plastics, rubber, copper wires, dirt and glass.
The urban centers also contribute immensely to the solid waste crisis in most countries today. Some of the solid waste brought about by the municipal services include, street cleaning, wastes from parks and beaches, wastewater treatment plants, landscaping wastes and wastes from recreational areas including sludge.
This refers to hospitals and biomedical equipment and chemical manufacturing firms. In hospitals there are different types of solid wastes produced. Some of these solid wastes include syringes, bandages, used gloves, drugs, paper, plastics, food wastes and chemicals. All these require proper disposal or else they will cause a huge problem to the environment and the people in these facilities.
Benefits of Solid Waste Management
Improper disposal of solid wastes originated from industrial, commercial, and residential areas can create unsanitary conditions, which leads to pollution and imbalance in the environment. It can create major health problems to both human and the other living beings and affect the entire earth. So by collection and treatment of solid waste we convert the harmful particle and turn them into environment friendly materials and also reuse for other purposes.

Plasma gasification is an extreme thermal process using plasma which converts organic matter into a syngas/synthesis gas.
RDF consists largely of combustible components of such wastes, as non recycable plastics, labels, and other corrugative materials.
Pyrolysis is used heavily in the chemical industry for thermochemical decomposition of organic material at elevated temperatures.
Anaerobic digestion is a series of biological processes where micro organism breaks down bio degradable material in absence of oxygen.
Bioconversion or biotransformation, is the conversion of organic materials, such as plant or animal waste, etc into usable products.
Waste autoclave is a form of waste treatment that uses heat, steam and pressure of an industrial autoclave in the processing of waste.
Composting is the key ingredient of organic farming where matter is being decomposed and recycled as a fertilizer and soil amendment.
A landfilling is a process for the disposal of waste materials by burial and it is the most common method of organized waste disposal.
Incineration is a high-temperature waste treatment system that involves the combustion of organic substances contained in waste materials.
