The Concern about Hazardous Waste Management
by Okoth Okoth \| 05-03-2020 18:30 0
The Concern about Hazardous Waste Management 1. cause of mass life and material damage and loss (disability, death, fire, explosion); 2. cause of environmental damages: potential water, solid, and air pollution (underground and surface drinking water); 3. cause of potential increased chemical bioaccumulation that is hard for biodegradability (chlorine containing chemicals); 4. cause of long term irreversible health risks (mutagenicity, teratogenicity, and carcinogenicity) 5. high concern of trans-boundary movement of toxic wastes; 6. cause of massive toxic health damages. Hazardous Waste Treatment Different technical options and alternative methods can be employed for the treatment. The end result needs to focus on making the waste non-harmful or less hazardous, reduce its volume and texture, separate for re-use, and isolate it for final disposal. Treatment methods include: A. Physical methods: drying, screening, grinding, evaporation, sedimentation, filtration, fixation, etc. B. Chemical methods: Oxidation, reduction, neutralization, hydrolysis, etc. C. Biological methods: composting, aerobic and anaerobic decomposition, activated sludge, enzyme treatment, etc. D. Thermal methods: incineration, boiling, autoclaving, UV treatment, microwave use, etc. Hazardous Waste Disposal: The hazardous waste, after treatment, can be ultimately disposed using the following methods: a) Land farming: the treated waste can be used as a fertilizer or soil conditioner with the approval of concerned regulatory entities; b) Deep well injection: a special kind of drilled well is prepared for such purposes. Brine (40% salt solution) is usually disposed in this manner. Precautions for water pollution need to be a concern. c) Surface impediment: encapsulation, fixation, or containment of the waste. This method involves arresting or demobilizing the movement or migration of the waste by containing it in a hard core: clay soil, thermoplastics polymers, non-corrosive metallic containers (carbon-steel tanks), cement, lime, fire glass, rocks. d) Ocean dumping: was mostly practiced from 1945 to the 1970s. Despite the existing public protest, this method continuous to be an alternative for the waste generators.

Hi Okoth Okoth, this is Sang Su Lee.

This article deals with the waste management and this is crucial in our lives because we are living in the nature in which we take the resources from. Unfortunately people are making stuffs that are not returnable to the ecosystem. This can be a problem in two aspects: Limited resources and harmful to the ecosystem.

As you mentioned in your article, I really hope waste management technique would improve soon and harmful waste would be dealt more perspicaciously.

Thank you for sharing this article.

Regards,

Sang Su

Hello Okoth! Greeting from your new mentor, Taehyun!

I read well with your writing! Hazardous waste management is a very serious problem. Modern civilization inevitably makes hazardous waste during the process like recycling of plastic or aluminum. (Because plastic is based on oil, plastic waste is hazardous to nature!) So it is really important how to dispose of this waste. But I didn't know about how to treat hazardous waste! Seeing these varieties of ways to treat waste, very insightful!

Thank you for your good writing! Cheers!
