The formation of solid urban garbage is inextricably linked to the expansion and increase of human activities. Technological advancements and increasing urbanization have increased the population's consumption of products (food and other consumables, organic and inorganic, degradable and non-degradable, etc.) and, as a result, contributed to an excessive volume of garbage.
Globally, around one billion tons of solid waste are created each year, with this amount anticipated to rise to more than two billion by 2025.
These wastes have serious consequences for public health and the environment. When trash is not properly handled, it becomes a source of pathogens (insects, animals, bacteria, and so on), harmful agents, and pollutants in the soil and water.
One of the most common kinds of solid waste management is the collecting and storage of garbage in regulated landfills.
What exactly is a landfill for Solid Waste Management?
A landfill, sometimes known as a sanitary landfill, is a garbage disposal site that is meant to safeguard the environment and human health. It's not the same as a public dump. Landfills are constructed to concentrate garbage in compacted layers to minimize volume and are monitored for the management of liquid and gaseous effluent to safeguard the environment and human health.
In addition to municipal solid trash, faecal sludge can be disposed of in landfills. Although well-constructed and managed landfills are safer than open dumping sites, even the greatest sanitary landfill will eventually fill up and begin to leak.As a result, only garbage that cannot be repurposed should be disposed of in landfills. Prevention of waste in the first place remains a priority in order to tackle present waste concerns.
Separating different sorts of garbage and reusing them is far more sustainable!
The Treatment Process and Fundamental Design Principles
A simple landfill is a trench with a protected bottom (to prevent groundwater pollution) in which rubbish is buried in layers, compacted, and covered. At the conclusion of each day, approximately 0.5 m of dirt should cover the dumped garbage to prevent animals from digging up the waste, flies from breeding, and stench, waste (e.g., plastic bags), or diseases from being carried by the wind.
The more advanced landfills have a bottom and side liner system, as well as a leachate removal system that comprises leachate treatment, groundwater monitoring, gas extraction (the gas is flared or utilized for energy generation), and a cap system.
There are both aerobic and anaerobic bioreactor landfills-
Bioreactor technology accelerates the biological decomposition of organic waste (e.g., food, plants, paper, etc.) at a landfill by encouraging the conditions required for the microorganisms that decompose the waste and produce biogas. The moisture content of the trash is the single most essential component in encouraging waste breakdown.To achieve an ideal moisture content of 35 to 45 percent water by weight, liquids must be added to the waste pile. The following liquids are added: previously recovered landfill leachate, gas condensate, water, storm water runoff, and faecal sludge or residual sludge from wastewater treatment facilities.
Once the landfill's capacity is achieved, it must be properly covered and the bottom must be monitored on a regular basis to ensure that no harmful effluent reaches groundwater sources. The cover should be resistant to wind and water erosion, encourage growth, and meet aesthetic, ecological, or end-use characteristics.
