Description of Eco Action
Please select only ONE: Year-long activity (Period Indication: on going since 2013 )
Title of Activity: SSMC Eco-Garden by Gardening Interest Group
No. of Participants: 8 Gardeners. The garden is open to all 1600 Staff of SSMC to enjoy and
relax.
Target Group: Staff (Please specify for others: )
Details of the Activity: SSMC Wafer Gardens was officially opened during SSMC EHS week in
Q3 2013. The idea to have a garden was inspired by a visit to SSMC’s adopted school. Our
CEO, Jagadish & the Management Team also wants to cultivate the culture where our
employees are actively supporting the preservation and conservation initiative within SSMC
premises. A group of colleagues came together and built the garden in less than 2 months.
The garden is located at the side gate of SSMC, facing our Pasir Ris community. Today, this
group of colleagues are known as the Gardening Interest Group. This interest group
represents our team spirit towards sustainability as well as a love for nature. The gardeners
create their own fertilizer by composting the unwanted fruit juice pulp from SSMC cafeteria!
In Aug 2014, the “fruits” of SSMC Eco Garden was recognized by the Singapore National Parks,
and we were much honored to receive the Bronze award certificate presented by Mr. Kenneth
Er, CEO of National Parks at Gardens by the Bay. The garden also went on to win the Best
Community in Bloom (CIB) Show Garden and Best Innovative Garden Design in 2015 during
the SG50 CIB awards. There are more than one dozen of plants, fruits & veggies that are
growing in the garden and the plot of gardening land has expanded to double its initial size
with the passion and effort from the interest group. Some of the garden harvest include lady
fingers, papaya, bitter gourd, long beans, sweet potatoes, bananas, pandan leaves, chilli &
herbs of all sorts.

Description of Eco Action
SSMC has embarked on the journey of conservation and reduction since 2002 with the aims
to reduce energy and water consumption, waste generation and CO2 emission.
Table below illustrate the various projects that SSMC has worked on over the years as our
conscious effort to be “environmental friendly”.
Measures to
conserve
resources
SSMC building is designed and constructed to world class standard in energy
usage. An energy audit has been conducted in 2006 to identify the processes that
consume the most energy. Programmes and projects were planned to focus on
reductions of processes identified thereafter.

Implementation of energy saving initiative by switching off Kitchen
mechanical system, 4 units of television sets and partial lighting in the
cafeteria. Reduce energy consumption by 44,190 kWh
Conversion of UPS flywheel conversion to voltage sag protection in 2014,
reduced energy consumption by 919,800 kWh.
Replacement of existing vacuum pumps with energy efficient models
between 2014 and 2016, expected reduction in energy consumption by
3,650,730 kWh.

Organised By:
Among the best Fabs in Singapore that recycle 70% of water.
Increased water reclaim from wafer fabrication process which reduced
157,680 m3 water consumptions annually since 2003.
Reuse and reclaim of AWR (Advanced Water Reclaim) and AOR (Advanced
Organic Reclaim) reduced annual water consumption of 113,800 m3 and
37,400 m3 since 2005 and 2006 respectively.
Other various water saving projects introduced since 2003, reduced
annual water consumptions by 324,747 m3.
Recycling of reused water at Local Scrubber, saved up to 12,000 m3 and
415,000 m3 of water annually since 2006 and 2012 respectively.
Improvements to Wet Bench, APM and HPM reclaim system reducing
water consumption by 200,020 m3 annually since 2013.
Increase reuse water for local scrubber systems reducing water
consumption by 7,300m3 annually since 2014
HF waste water reclaim project and Organic waste water reclaim
improvement project in Oct 2015, reduced Newater intake 890 m3/day
(324,000 m3 per year)
Reclaim water from Fluoride waste water discharge saved
131400m3/year
