thermoelectric,...;
managing many projects/programs at
state level: KC 07-04, KC 08-02, KC 08-04; KC 08-06 etc. at
ministrial levels and locality.
Up to 12/2004, about 1,100 articles and reports have
been published by FES staff. FES also has coordinated with
World Bank (WB); Asian Development Bank (ADB); UNICEF;
UNEP; UNDP; CIDA; EU and Flemish Community of the Kingdom
of Belgium to carry out research, studies and exchange
training. FES staff have attended many international
conferences and symposiums on environment.
FES
students
have
actively
carried
out
and
participated in
research and field studies. They have
achieve many good prizes (1 first; 2 second and 1 third
prizes)
in
different
levels
(Ministerial;
National
university) and other competitions which are sponsored by
International organizations/NGOs (Sonny Green Invention: 2
second and 3 third prizes; UN Wetland Ambassador, etc.).
FES students also effectively take part in many Youth
movements such as "Green Summer".

II. PROJECT DESCRIPTION
With
rapid
development
of
idustrialization
and
mordenlization
processes,
industrial
waste
has
been
dramaticaly increased both in amount and kinds. It requires
adequate awarness, behavior and proper investment for waste
treatment icluding solid wastes. Sludge dischaged from
metal electricplating contains high amount of heavy metals.
It is hazardous waste for organisms and harms human health.
Resulting from previous studies organisms/livings could be
killed or degragated by sufficently high concetration of
heavy metal. Low concentration can cause chronic poison or
bioaccumulation affecting organisms in long-term times,
particularly heavy metals comtaminated in environment
propably cause adverse effect to human health through food
chain.
Heavy metal rich sludge treatment methods majority are
puting ash into cement box then disposed/land filled;
incineration. The treatment methods for reuse of these
wastes (including sludge from wastewater, heavy metal rich
sludge from recovery process of electroplating damaged
products) have been studied by many researchers and
obtained good results. However, in Vietnam this issues has
not sufficiently been studied and implemented.
Current economic development has increased significant
demand in consume and services, especially eat and drink
services. Besides socio-economic benefits these social
servises have created some environmental issues like
generation of a large amount of used tissue-paper/napkins.
The
amount
become
increasing
together
with
rapid
development of hotel and restaurant system. This solid
waste actually is a huge source of xenlulo which can be
treated to reuse as raw material/subtrate for mushroom
cultivation.
6
Mushroom is a kind of clean food, rich in nutrient and
pharmaceutical product. Currently, mushroom cultivation is
a great potential job with good income and appropriate to
rural/agricultural areas of Vietnam.
At the moment we are facing on the pressure of rapid exhaustion of natural
resource. Wastes therefore should be considered as a special type of resource. In order to
contribute in this research area we have implemented a project : Study on
treatment technology and reuse of solid wastes. (Case studies:
Treat and reuse of heavy metal rich sludge of Goshi-Thang Long Company as a
ceramic pigment and construction additional material and Treat and reuse of used
tissue-paper/napkin for mushroom cultivation)
Objectives and research contents
1. Premininary treatment of solid waste rich in heavy
metals (Crom, Nikel, Iron)
2. Testing of reuse solid waste as :
- Additional materials in colour blending (pigment) in
pottery and ceramic production
- Additional
production
materials
in
raw
pottery/ceramic
- Additional materials in production of enamellel tiles
for house floors and pavements and red enamellel
tiles (bricks)
3. Treatment and reuse of used tissue-paper/napkin as a
new raw material (substrate) for mushroom cultivation.
First,
used
napkin
has
been
treated
by
natural
fermentation, a suitable fermentation time is selected to
achieve the highest yield. Then, appropriate operation
parameters such as temperature, moisture content, pH and
time for mushrom growing are identified.

Treatment
of
wastes/residue

cultivation to produce microbilogical fertilizer
mushroom
Innovation ideas of the solutions
Reuse
(pigment)
of heavy metal rich waste as color enamel
in
pottery
and
ceramic
production
is
an
7
innovative and original selection. It based on the fact
that wastes containing heavy metals have similar color as
that from inorganic colouring powder used in pottery and
ceramic production. Currently, in Goshi Thang Long Company
everyday more than 1 ton of heavy metal rich sludge has
been discharged (with the disposal fee of 2 mil. VND/ton).
This increase production cost and also environmental hazard
because heavy metals from waste could be released and
contaminated to environment. A treatment of waste in
laboratory: drying, grinding, siewing (with size 0,025 mm),
and being used as color pigment with different ratios and
as additional materials in raw pottery production has a
great
scientific
and
innovative
meening
because
it
increases Company’s profit and at the same time reduces
negative impacts on environment. The studies have been
implemented in pottery and ceramic production enterprises
Quy Mao, Bat Trang and Construction Company 27-7 in Thanh
Son, Kim Bang Ha Nam
During recent years mushroom cultivation has strongly
been developed. However, the cost of traditional raw
materials like rice straw, cotton waste, sugar-can solid
waste, sawdust etc.) is also increasing (e.g. 1 ton of
cotton waste now costs 900.000 VND). Thus, a introduction
of alternative raw material replacing gradually traditional
raw material is a significant way in terms of science and
practice.
Project Impact
The Project has a positive socio-economic impact on the
target groups: manufacturers (reducing disposal expenses);
project participants; hotel and restaurant owners; small
producers (using waste as raw materials); local people
(creating jobs and incomes).
Furthermore, the project contributes into transition
of production structure, diversifies products; Promotes
awareness
on
environmental
production;
reduces

Dissemination Potential
The initiatives on treatment and reuse of different
kinds of solid wastes can be applied for similar kinds of
solid waste and the use of treated wastes as raw materials
could also be disserminated in different production
enterprises and communities.
