Phu Dong Textile Co., Ltd is founded in 2006, specializes in
manufacturing grey fabric and interlocked and sized fabric according to
the demand of markets. Products are mostly for domestic markets such as
Central region, Hanoi, and Ho Chi Minh City, 40% of the products are
exported to European, Korean and Japanese markets. The capacity of
plants is 5,000,000 m of sizing and warping per year, and 2/ 1,000,000 m
of raw fabric per year
Before applying CP, the serious problem
of the company is pollution caused by wastewater and exhaust fumes.
Wastewater of company has exceeding the limit values in the standard
TCVN 5945-2005, (COD (140,5mg/l) was exceeded 2,8 times, BOD (73mg/l)
was exceeded 2,43 times and TSS (132mg/l) was exceeded 2,64 times.
Company’s exhaust fumes generated from fuel burning and boiler
operation. CO content (1.264mg/m3) in exhaust gas was exceeded 1.2 times
in comparison with the limit value in National Standard. For solving
these problems, in 2009, the factory received the support from the
Ministry of Industry and Trade via the Cleaner Production in Industry
Component (CPI) to conduct Cleaner Production Assessment and
Application.
Under the MOIT support, in 2009, the company had
implemented CP assessment. In the 1st phase (from July 2009 to February
2010), the Company established a CP team led by Mr. Doan Xuan Tinh
–Director of the company and other 6 members to assess the whole
production line. The Team has conducted a walk-through assessment on the
tea production line at place. After the assessment and identification
of waste streams, the Team has conducted mass and energy balances for
the whole production line. All collected data have been used to analyze
and identify Cleaner Production options for each production step
After
conducting CPA and identifying improvement options, the Company has
carried out 9 no-cost and low-cost options with a total budget of VND 50
millions. Such application has reduced material and electricity
specific consumption to 20% and 3.4% respectively and saved 230 million
dong. In the second phase (from March 2010), the Company has actively
implemented high-investment options to improve the product quality and
solve completely the environmental issues at place and received CPI’s
support (2 billion dong) to install by a 3pass- horizontal boiler,
update and repair sizing machine, install new automatic splicing
machine, install dust suction and filtering system to improve
environment working. Benefits from those solutions are 1.2 billion dong
by reducing raw material consumption and reducing environment treatment
cost.
Particular benefits derived from Cleaner Production are as follows:
Technical benefit
| Economic benefit
| Environmental benefit |
Phase 1
|
Reduction of 20% specific consumption of material
| Saving of 1 billion dong
| Significantly improve the working environment of the factory workers |
Reduction of 3.4% specific consumption of electricity
|
Phase 2
|
Reduction of 37,8% specific consumption of material
| Saving of 1,2 billion dong
| Reduction of 130 tons of CO2/year to environment Reduction of 1.5 tons of residual yarn, waste yarn/year
|
|
|

6 | Install transparency sheets at ceiling of the work shop for using natural light
| 2.4 million dong | EM |
7 | Replace 40 filament lamps of 40W by 10 compact ones of 15W | 0.6 million dong | EM |
8 | Install by a 3 pass- horizontal boiler 1,4 billion dong
| 1.4 billion dong | Saving of 508 million dong/year; reduction of 1,700 m3
of wood /year, 42 tons of coal/year, reduction of 3,000 tons of
CO2/year
| EM |
9 | Install sizing machine
| 3,5 billion dong | Saving up 1.3 billion dong/year
Reduction of 738 kg of solid waste
Reduction of 30% of size chemicals Reduction of 30% of total amount of water use for sizing process | EM |
10 | Install new automatic splicing machine (take only 30seconds for every splicing, reducing losses
| 600 million dong | Saving of 232 million dong/year | TC |
Remarks: GH: Good Housekeeping; EC: Equipment Change, TC: Technology changePerceiving
the benefits from CP application, the factory insisted to maintain the
CP team activities and integrate CP in the general management system at
place. In order to facilitate CP application, a simple environmental
management system has been developed. The factory has also set up
environmental policy, whereby it is requested that the environmental
protection law and other regulations should be followed strictly,
ensuring the sustainable development of the company and reducing waste
emission sources. The factory has integrated process management system
with the environmental management system, therefore, energy and material
consumption is monitored at the same time with the monitoring of
pollutant parameters in the waste streams. A sample system and legal
procedures are built and applied for environment data collection,
checking, classification and data analysis.
An environmental
monitoring plan has been initiated. The aim of the plan is to monitor
significant improvements from applying CP or to adjust if there is any
reduction in environmental benefits. Environment monitoring system
includes monitoring air quality and wastewater.
CP not only
brings about benefits from energy saving, emission minimization, reduced
water consumption, but also helps the Company increase production,
improve product quality, and prove prestige. The implemented CP options
at the Company are a typical case study for enterprises in the sector of
textile production in Vietnam./.
