Collection and Disposal of Wastes

Municipal solid waste management systems are built around the collection and disposal of garbage and other waste. 

The primary goal of a waste collection strategy is to collect, in a timely and cost-effective manner, as much correctly source separate waste as possible, in order to make the subsequent waste sorting and or treatment stage as simple as possible, with the ultimate goal of increasing re-use and recycling.

Garbage management authorities develop and implement waste collection strategies that are based on the features of the collecting zone (e.g., population density, types of buildings) as well as the public’s acceptance of various waste collection methods, among other factors. 

The optimal number of separately collected waste fractions for their situation, the targets established in the local waste management strategy and those set by national or European legislation, local residents’ attitudes toward the environment and perceptions of the environment, as well as seasonal variations, are all factors to consider.

Best practices should be followed. Solid waste collection services for families and businesses, where applicable, are provided by door-to-door or kerbside collections, or at municipal garbage collection centres, depending on the location of the collection service. 

Collection rounds are often offered for the most voluminous MSW fractions, with municipal waste collection centres that accept a broader range of waste streams, such as waste electrical and electronic equipment, as part of their service. 

For additional waste fractions, complementary systems can be utilised, for example, bring systems that target specific waste fractions such as glass can be brought into the system.

A typical waste collecting strategy executed by leading waste agencies would comprise the following components

Food waste should be collected on a frequent basis (e.g., weekly or more frequently depending on the climate and season).

Mixed waste should be collected on a less frequent basis (e.g., every two weeks); recyclables should be collected on a frequent basis (e.g. paper, cardboard, cans, plastics, glass), individually source separated where public acceptability allows, otherwise co-mingled and sorted at a material recovery facility; glass, followed by paper and cardboard, should be collected. 

The establishment of a convenient network of civic amenity sites that receive all waste fractions from residences that are not collected door to door or in street containers, including hazardous trash and biowaste (e.g. from gardens)

Conversion of biodegradable waste into compost

Organic waste that can be broken down into carbon dioxide, water, methane, or simple organic molecules by bacteria and other living things through composting, aerobic digestion, anaerobic digestion, or other similar processes is classified as biodegradable trash.

Composting is the process of building a pile of wetted organic matter known as green waste (leaves, food waste) and then waiting for the materials to decompose into humus over a period of weeks or months, depending on the temperature.

Choking of cattle’s throat due to swallowing of plastic bags 

The cow is classified as a ruminant. This implies that it almost swallows the food before bringing it back to the mouth when it has the opportunity and chewing it again before sending it back to the stomach for digestion.

 The stomach, on the other hand, contains four chambers. 

When a cow consumes plastic, the plastic enters the stomach and remains there for the majority of the time.

 Over time, the plastic accumulates and might cause a blockage in the stomach’s digestive tract.

A clogged stomach in a cow is a potentially lethal situation. 

The stomach of a cow contains bacteria that aid in the digestion of the food, and the bacteria also creates a lot of gas as a result.

 The gas is forced out of the stomach by the movement of the stomach. 

Once the stomach is obstructed, this movement is hindered, and the gas builds up in the abdomen. 

The end outcome will be a severely swollen stomach, which will result in a horrible death.

Improper disposal and air pollution

Our atmosphere becomes increasingly polluted as the world becomes hotter and more crowded, our engines continue to spew out polluting emissions, and half of the world does not have access to clean fuels or technologies (such as stoves or lamps). 

Nine out of ten people now breathe polluted air, which kills 7 million people every year.

Air pollution is difficult to avoid no matter how affluent the neighbourhood in which you live.

 It can be found everywhere around us. 

Our bodies’ natural defences against microbes in the air can be overcome by contaminants in the air that penetrate deep into our respiratory and circulatory systems, harming organs such as the lungs, heart, and brain.

It is well known that air pollution and climate change are closely related – the primary cause of climate change is fossil fuel consumption, which is also a major contributor to air pollution – and that measures to mitigate one can benefit the other. 

The United Nations Intergovernmental Panel on Climate Change (IPCC) issued a warning this month that coal-fired electricity must be phased out by 2050 if we are to keep global warming to 1.5 degrees Celsius.

 If this does not happen, we could be facing a catastrophic climate crisis within 20 years.

Conclusion

Waste created in campus laboratories and shops cannot be disposed of in the usual trash or down the drain because they include chemicals that are toxic to humans and animals.

 In the United States, many of these wastes are governed under the federal Resource Conservation and Recovery Act (RCRA).

 When a project is in the proposal stage, it is critical to assess the amounts and types of trash that will be generated in order to guarantee that a disposal option that is both legal and inexpensive exists—and to reduce the quantity of waste generated. 

Every individual bears some level of responsibility for the generation of waste.

As part of a municipal landfill diversion programme, waste collection involves the collecting of recyclable goods at the curbside that are technically not rubbish.
