Nowadays, how to manage solid household waste effectively is a great concern for officials throughout Vietnam.
Background / Description
Solid
household wastes are wastes from the lives and activities of human and animal.
Wastes are produced from households, industrial zones, public places, malls,
from agricultural activities, constructions, from hospitals, waste treatment
facilities, etc. In particular,
solid household waste accounts for the highest proportion.
The
amount and constituents of waste differ in each province, country or area,
depending on the local policies, economic
and technological development, as well as the awareness and literacy level of
the people. Every activity in the normal course of living, doing business,
travelling, etc. produce a significant amount of waste.
Common solid waste treatments:
·
Incineration: This is the most common
treatment for solid wastes globally, especially for toxic industrial wastes and
harmful medical wastes. The treatment of fume from the burning is an issue that
demands special attentions.
·
Sanitary landfill: This is the simplest and most common treatment. Landfills
are usually used to treated non-reuseable municipal wastes, ash from
incinerators, and industrial wastes. Harmful and radioactive wastes are also
buried in specifically-designed landfills.
·
Composting:
This treatment is used on non-toxic organic matters by first dehydrate, then treat until it becomes porous and
moist. The final results of the decomposing process are carbon dioxide , water
and stable organic compounds such as lignin, cellulose, fibers, etc.
·
Recycling:
Recyclable wastes such as metal, plastic and paper are sold by households to
junk collectors, then transferred to crafting villages. The recycling
technologies in crafting villages are mostly outdated, the infrastructures are
lacking, the businesses are small-scaled, leading to severe environmental
pollutions in some areas.
Technical
Specifications
Seeking advanced treatment technologies meeting
the following requirements:
·
System capacity range: 50 tons/day; 100 tons/day;
600 tons/day;
·
Buried proportion after treatment: less than 10
percents;
·
Technology meeting standards of Ministry of Natural Resources and Environment and
current technology transfer regulations;
·
Technology
is reliable (applied in some areas in Vietnam with good results);
·
Reasonable
treatment cost for each waste unit .
Form of Cooperation
Consultancy and full transfer of technology.
