Waste Management

By - Swati yadav

 Keeping our environment clean is essential to living healthy and comfortable lives. People, factories, processes and animals produce waste every day, so it is an inevitable part of the society.

There are 5 major types of Waste:

1. Liquid waste

Liquid waste refers to all grease, oil, sludges, wash water, waste detergents and dirty water that have been thrown away. They are hazardous and poisonous to our environment and are found in industries as well as households. Wastewater, as it is often called, is any waste that exists in liquid form.

 

        2. Solid Waste

Solid waste is any garbage, sludge, and refuse found in industrial and commercial locations. The five major types of solid rubbish are;

• Glass and Ceramics: Numerous companies readily recycle ceramics and glass.
• Plastic waste: Plastic waste is any container, jar, bottle, and bag that is found in companies and houses.
• Paper rubbish: This refers to all newspapers, packaging materials, cardboards, and other paper products.
• Metals and Tins

                                  

       3. Organic Waste

Organic waste refers to rotten meat, garden and food waste. This type of rubbish is commonly found in homes.

4. Recyclable Waste

All discarded items like metals, furniture, organic waste that can be recycled fall under this category.

5. Hazardous Waste

Hazardous waste includes flammable, corrosive, toxic and reactive materials. In a nutshell, they are wastes that pose a significant or potential threat to our environment.

 

 Waste Management (or waste disposal) includes the processes and actions required to manage waste from its inception to its final disposal.[1] This includes the collection, transport, treatment and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, economic mechanisms. 

 

Waste can be solid, liquid, or gaseous and each type has different methods of disposal and management. Waste management deals with all types of waste, including industrial, biological, household, municipal, organic, biomedical, radioactive wastes. In some cases, waste can pose a threat to human health.[2] Health issues are associated throughout the entire process of waste management. Health issues can also arise indirectly or directly. Directly, through the handling of solid waste, and indirectly through the consumption of water, soil and food. Waste is produced by [3] human activity, for example, the extraction and processing of raw materials.[4] Waste management is intended to reduce adverse effects of waste on human health, the environment, planetary resources and aesthetics.

Waste management practices are not uniform among countries (developed and developing nations); regions (urban and rural areas), and residential and industrial sectors can all

 take different approaches.

METHODS TO MANAGE WASTE:

● Recycling  :

Recycling is the process of collecting and processing materials that would otherwise be thrown away as trash and turning them into new products. The great thing about this waste management system is that it has economic and environmental advantages. It saves the government resources needed for waste projects, provides thousands of jobs, and will make a decent deal of money. Only bring recyclable waste to the closest recycling centre to get money from recycling.

● Incineration

This type of waste management includes the disposal of waste materials by means of burning. The thermal treatment is another name for this disposal method. You may incinerate on a commercial or human scale and dispose of a broad variety of waste materials. Most countries with limited land consider the incineration process. You may use the power produced by burning waste materials to produce heat, energy or steam. One of the drawbacks of this disposal process is that it can be a source of air pollution.

● Landfills

 It is one of the most popular types of waste management systems in the world. It includes the collection, transportation, disposal and burying of waste in designated property. Many towns are planning deserted and barren areas to cope with waste. 

Authorities are committed to ensuring that the construction of each landfill is successful in terms of sanitation and economic land use. However, landfill sites are a significant cause of health and environmental problems that concern many communities. For instance, gas from these landfills is often incredibly dangerous. 

●  Biological Reprocessing

Chemical waste materials, such as kitchen waste and paper goods, can be reused after a procedure called biological reprocessing which is another popular system amongst the varied types of waste management. Multiple physiological systems, including recycling and biomass gasification, are used in biological reprocessing. Composing is a normal biological mechanism that is carried out under control conditions. One of the ends of the stock is natural gas, which is used to produce heat and electricity. Biological reprocessing is commonly used for the disposal of industrial waste.

● Animal Feed

Food waste is a serious issue and needs serious consideration. According to the United States Department of Agriculture, between 30 and 40 percent of all food created by the United States is spent on food by retailers and customers. This is a major problem as the food value is estimated to be $161 billion. The nation is leading the world in terms of food waste, and the cause is self-explanatory. Food can be preserved by manure and livestock feed and this is also one of the ecological types of waste management methods.
