2013 APEC Carbon Labeling Workshop
DA.AI’s Green Mission
Date: March. 12. 2013Presenter: Ting HungCompany: DA.AI Technology Co. Ltd. (Chinese Taipei)

Funafuti, the capital city of Tuvalu in the South Pacific island has reached the highest sea level ever in this season.

Over the past 80 years, global warming caused about 10 cm rise in sea level.

Landfill = Emitting 0.27 million tons of CO2-e
Incineration = Emitting 8.49 million tons of CO2-e
In 2010, the global bottled water consumption was about 237 billion L ≈ 6.85 million tons of waste non-degradable PET plastic!

Recycled and processed into chips
for textiles =
Saving 7.59 million tons of CO2-e !!
*As compared with using virgin materials
Recycled polyester fabric - the mainstream eco product

Reasons of limited expansion of the recycled polyester market:
Uneconomical as raw material Instability of the recycled material Unable to meet quality expectations
1 kg PET bottle requires 3.12 L of crude oil. One PET bottle contains at least 90% of
reusable polyester fiber.
Environmental conservation refined from the source Environmental conservation refined from the source

Carbon emission indicator Carbon reduction indicator
Clearly indicates the CO2-e emitted during the life cycle of the product, either single- or multiple-staged.
Indicates the amount of CO2-e of the product reduced in a certain period of time as planned.
Low-carbon mark Carbon-neutral mark
Indicates that the product has a lower carbon emission among equivalent products, or declares that the CO2-e emission of the product has been reduced to a certain level.
Indicates that the product has reached carbon neutral through carbon exchange.
Carbon level indicator Environmental indicator
Indicates the carbon level of the product among equivalent products by using grade, star or tier system.
Indicates other environmental impacts in addition to carbon emission.

Our carbon reduction commitments
DAAI aims to reduce the carbon footprints of its products by 3% within 3 years by:
1. Establishing an effective recycling management system to improve the purity of the recycled PET fiber.
2. Establishing a carbon reduction management system to promote ‘green procurement’.
3. Improving the functionality of the products (e.g. increasing dirt resistant properties, reducing fiber weight etc.).
4. Implementing carbon reduction measures in offices.
First phase:Promote carbon labeling
Second phase:Develop low-carbon mark

Combining the contributions from DA.AI Tech., ITRI and Tzu Chi Recycling Stations
Waste plastic bags collected in Tzu Chi recycling stations
Recycled plastic bags nicely re-sorted by volunteers
Recycled plastic bags broken into little pieces (about 1 cm)
Broken plastics fed into ITRI pyrolysis equipment
Lastly, pyrolysis oil is formed

Occupied area: 5m × 5m × 6m (Double-storey) No. of technicians required: 2, training required
Production efficiency:
Conditions : 75% liquid yield, 20 kg/h feeding rate, 30 working days/month, 12 working h/day
One pyrolysis unit can handle 20*12*30 = 7.2 tonnes plastic bags/mth ~ 96 thousands bags/mth
Oil production = 20*0.75*12*30 = 5,400 kg oil/mth = 6,750 L/mth
Main application: The ‘plastic-pyrolysis oil’ can be used
as boiler fuel for DA.AI’s future R&D center

Recycling PET bottles for chip production in place of incineration:
Note: Calculations were made using WARM, USEPA, with an assumption of average bottle size 600 mL and 27 g in weight.
Recycled 254 million PET bottles
Saved 4.26 million L of crude oil
Reduced 16 million kg of CO2-e
