 Waste management plays a noticeable role in controlling waste materials of human society without harming the environment. Our world would be worse a place if we stopped recycling, processing, reducing, and disposing of garbage that we create every single day. For example, the average person generates about 4.5 pounds of trash per day, while more than 2.12 billion tons are produced each year. There are various categories of waste on the planet and these are managed with different functions. Recycling Recycling itself is divided into three main types. Mechanical recycling, which is the most common one, plastics or other waste disposal are transformed to produce new materials. It is mostly used to make garbage bags, floors, new packages, and many more. Energy recycling- with the help of incineration plastics are converted into thermal and electric energy. Chemical recycling-in order to be used as raw material, plastics are reprocessed with modified chemical structures. Landfill process Sanitary landfills are designed to bury the trash to be isolated from the groundwater, rain, air. This type of landfill uses two ways; the trench and the area method to prevent hazardous substances. Municipal Solid waste landfills(MSW)- household garbage is collected and regulated by local governments and they are turned into MSW’s disposal, but some items such as motor oil, batteries, chemicals, etc are prohibited. Biological reprocessing The purpose of this process is to speed up the natural decomposition of organic matter and it recycles the waste materials like plants, food scraps, and paper products.

Hello Sara, this is your mentor Hannah.
Sorry for the late comment.
Great article on types of waste management: recycling, landfill process, and biological reprocessing.
Since we don't have infinite amount of landfill, I hope it is least-used.
For that, toxic wastes should be reduced, right?
Thank you for your great article and please keep up with your wonderful work :)

Hello Sara, this is your mentor Joon!
There are different methods of waste managements, and those methods you have mentioned ,recycling landfills, and Biological reprocessing, are quite popular ones. One I would like to
give a point is biological reprocessing and incineration that is being researched in recent days.
Scientists have found out the ways to obtain gas from decomposition process that could be
used as fuel for generation. Scientists also found that if incineration process reaches certain
level of temeperature, no waster materials were emitted. Aren't they interesting? It would
be good if you can also look them up on your own.
Well read, and let's keep up!
Best,
Joon
