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.
Energy conservation initiatives
i.  Awareness among the staffs to switch off lights/computers after work
ii.  Implement energy efficient air-con – auto switch off after work
iii.  Replacement of all lighting to energy efficient lights
iv.  Regular learning and sharing with Parent Companies for advanced energy saving technologies
v.  Monthly monitoring on energy and water usage for improvement opportunities
vi.  Annual stack air emission and monthly waste water monitoring adhere to local legislations
Energy Saving Projects
i.  Chiller water system optimization programme reduced energy consumption by 605,900 kWh annually since implemented in 2003.

vi.  Improvements to optimize scrubber performance reduced energy consumption by 50,000kWh since 2012.
vii.  Acid Exhaust diversion project reduced energy consumption by 1,030,037 kWh annually since 2006.
viii. Switched off 21 units of electrical static transfer switches of uninterruptable power supplies, reduced energy consumption by 45,245 kWh since 2013
ix.  Fluorescent lamps retrofitted with LED units in 2014, reduced 1,375,293 kWh per year
x.  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
xi.  Conversion of UPS flywheel conversion to voltage sag protection in 2014, reduced energy consumption by 919,800 kWh.
xii.  Replacement of existing vacuum pumps with energy efficient models between 2014 and 2016, expected reduction in energy consumption by 3,650,730 kWh.
Water Saving Projects
i.  Among the best Fabs in Singapore that recycle 70% of water.
ii.  Increased water reclaim from wafer fabrication process which reduced 157,680 m3 water consumptions annually since 2003.
iii.  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.
iv.  Other various water saving projects introduced since 2003, reduced annual water consumptions by 324,747 m3.
