In order to achieve the goal of reducing CO2 emissions, in addition to using electricity sensibly, SRV ismaking efforts to convert the energy (created from burning coal and fossil fuels) to clean energy
sources such as solar energy. In addition, SRV also gradually replaces equipment that consumes a lotof power to equipment with modern technology, increasing efficiency and saving energy.

In 2022, the company was able to return to using VOC-free adhesives after more than a year ofdifficulties in importing this glue from foreign suppliers. In addition, the company also cooperates withthe Japanese factory to promote research and development of products that do not use adhesives toreduce VOC emissions into the environment.

In 2022, SRV had some waterleakage incidents due to damaged
water pipes after a long time ofuse. The amount of water used fordomestic purposes also increased,leading to the failure to achieve
the target of water reduction. 4

INSTALL NEW AIR
CONDITIONERAt the end of 2022, SRV installeda new air conditioner in the Feedprocessing area. The new airconditioner with a capacity of 6.8kwh can replace the two old airconditioners with a total capacityof 8.1 kwh. Thus, the replacementof air conditioners, in addition toensuring a working environment
for workers, will also contributeto reducing power consumption
and reducing CO2 emissions into
the environment. With the new
type of air conditioner, cold air
will blow in the fabric duct and beevenly distributed to the work
areas through small air holes on
the pipe.
Annually, the company will
gradually
replaceoldairconditioners with poor cooling
performance but consume a lot ofpower into new, energy-saving,
using
anew

Realizing that some emission points are located close to each other and have similar
emission characteristics, SRV has combined emission points from 15 points to 9
points to reduce environmental monitoring costs (1300USD/year) and reduce
system maintenance and repair costs.
