Cleaner technology implementation
Introduction of cleaner technology
In the first stage, the company participated in a project called “Promotion of Cleaner
Technology in Thailand,” implemented by the Thailand Environment Institute (TEI) with
support from the Danish Cooperation for Environment and Development (DANCED) and
Federal of Thai Industries (FTI). The project focused on water and energy conservation
options for implementation in the initial stages, as follows:
• replacing worn out pipes;
• installing steam piping insulation;
• enhancing boiler efficiency; and
• implementing simple good housekeeping
practices such as installing water meters,
level controllers, and flow control nozzles.

Standardisation of color-matching procedures.
The company participated in the Research Cooperation Project on
Dyeing and Finishing Industries in Thailand by Technology of Cleaner
Production, supported by the New Energy and Industrial Technology
Development Organisation (NEDO), Japan, and the Department of
Industrial Promotion (DIP). The project aims to eliminate the re-dyeing
process by improving working procedures for staff and using
computerised matching devices.
Accurately matching colours is vitally important to the
quality of products. In the project’s implementation, an
expert from Kurabo Industry Company, Japan, conducted a
short-term study to identify opportunities for improvement
in the working procedures of laboratory staff. It was found
that the quality of the colour-matching process was mainly
based on staff experience. It was also found that factors
affecting the end-result of matching, such as temperature and

water volume, were not properly controlled, which led to
errors in colour matching.
Consequently, standardised working procedures, such as measuring instrument selection and
solution preparation, were introduced to ensure more accurate colour matching. In order to
improve working procedures, laboratory staff were trained on how to achieve uniform colour
mixtures. Working conditions were also carefully controlled; a highly sensitive weightmeasuring
device was moved to an air-conditioned room to avoid disturbances from electric
fans, and a computerised colour-matching device was installed in order to enhance matching
efficiency.
Boiler and steam trap retrofit
Steam is one of the necessary results of the heat transfer process.
The factory periodically conducts an energy audit and
benchmarking to monitor inefficiencies in the process.
Consequently, top management decided to participate in the
Steam System Project in order to improve energy efficiency in
the steam generating and recovery system. This development by
Sinsaenee Company was selected as a pilot project for steam
trap installation. The steam trap is an automatic valve that
catches and releases condensate into the piping systems, thus
preventing the release of steam and ventilating air into the
system.
