One of the foundations of a progressive society is efficient waste management. A city or town may have large malls, top-class hospitals, and an entirely built telecommunications network. Still, it will see health issues, environmental deterioration, and unsanitary living conditions if it can not handle its waste.
Reducing, reusing, and recycling the three Rs may sound cliched, but they form the foundation of every waste management practice. Imagine if, for instance, plastics were reused and recycled annually. Although landfills would not be quickly depleted, the amount of energy and cash saved would be enormous.
Some management methods, since they have been tried and tested, are considered top solutions. They are taking a look at how they serve residential and industrial waste management.
Recycling is not inexpensive, and the process uses more time for some materials. However, attempts should be made to follow through once certain items that can be recycled are established.
Some of the advantages of spent catalyst recycling include creating revenue by selling the material, saving space for landfills, and extending items' lives. Of course, it might be necessary to handle and sample the materials, but it is part of most production methods, so it does not pose a problem.
Composting is an organic matter's regulated decomposition and can be practiced on a small or large scale. It creates fertilizers that are nutrient-rich and can be resold and used to reap good benefits. Like hazardous waste transport, composting produces income and provides opportunities for jobs. It can also decrease the spread of pathogens if done correctly. The landfill room is saved as well.
The strict control of runoff and insects and the need for adequate space to compost on a wide scale are a few composting areas that beg to look into.
Rendering includes handling the carcasses of animals to transform them into usable goods. Slaughterhouses, for instance, produce tons of waste such as horn, bone, and inedible tissue. It is time-consuming and cost-prohibitive to dispose of them. Meanwhile, rendering addresses this issue and produces revenue.
The practice works its way into many of the things that we use. Like the steel rolling industry, animal feed, candles, and soaps make full use of it.
Incineration, in controlled conditions, is the combustion of waste. Hazardous waste that can not be recycled or composted is fed to incinerators at too high temperatures that burn them. Reduction of waste volume, elimination of pathogens (like a disease-carrying medical waste), and reducing waste toxicity are the key benefits of the practice.
Residue formation and the ability to create unwanted byproducts are a few downsides to incineration. Not every town or small city can have a facility because it is a closely regulated operation that involves detailed expertise and specialized equipment.
Other waste management practices can be adopted, but they should only be placed in place if it is not feasible to use the above approaches.
Open Burning: Open burning refers to the open-air burning of waste. It is routinely pursued by developed countries that don't have proper waste management procedures. While it benefits from not needing waste transportation and precious metals recovery to a disposal site, air pollution is induced, and contamination will spread. Many states also ban the practice, and there are limits on licensed pages.
Burial: Burial is equivalent to composting, but it refers not only to organic matter. Unless strict monitoring is performed, it is not an advisable activity as it can contaminate soil and water supplies and attract scavengers if not buried at the required depths.
