In support of the sustainability thought across the world, we began promoting green product actions in 2004, with Green Material, Green Manufacturing, Green Transportation and Green Design as the main features of our green product management system. Apart from promoting green product development, we enable more products to pass Green Mark certification to meet the goal of sustainable development.
Green Material
In addition to introducing the green accounting system to collect and analyze green purchase performance, Coretronic purchased green materials to thoroughly implement green supply chain management. The total purchase amount of green materials for the plants in Taiwan and China in 2021 occupied 97% of the total purchase amount in the same year.
| Year | 2019 | 2020 | 2021 |
| The amount of green material procurement (NTD 100m) | 124.7 | 153.7 | 231 |
| The amount of material procurement (NTD 100m) | 128.6 | 159.8 | 238.1 |
| The percentage of green material procurement (%) | 97% | 96% | 97% |
Green Manufacturing
Product Carbon Footprint Inventory
- The carbon emission at each phase of the product life circle can be analyzed with reference to the carbon footprint inventory. The product subject to carbon footprint inventory in 2021 was 12'' backlight modules (BLMs). The result of the inventory showed a carbon footprint of 2.46 kgCO2e/pcs (i.e. 0.0095kg of carbon footprint per gram of products), 7.9% less than the carton footprint of the same product in 2020.
- Due to the package reduction design, improvement for manufacture, and various energy-saving measures, Coretronic successfully reduced the product carbon emission.
Light Guide Plate Manufacturing Process Improvement
- Regulate the production temperature and save 0.25 kWh of electricity per hour. In 2021, the production hours were 2,321.4 hours, with electricity saving of 580.4 kWh and carbon reduction of 0.29 tCO2e.
Green Transportation
Green Packaging Material
To realize environmental values, we optimize the packaging design, use recycled paper to make wrappings, and adopt environment-friendly ink to print and simplify packaging.
Molded Pulp
Molded pulp is made of recycled waste paper. In 2017 Q1, we began verifying molded paper packaging materials with the drop test and the storage test. After passing the tests, it will be used in packaging. Such kind of natural, non-toxic, lead free, decomposable, pollution free, and waste free buffering material can effectively reduce the variety packaging materials and the quantity of packaging. Along with soy ink printing and package simplification, everything is eco-friendly. In 2021, 68% products used molded pulp.
Design-Size Reduction
It has been applied to the product platforms of R70 projector to reduce 42% packaging materials.
Use shipping cartons made from recycled pulp and attached with the Green Mark
The waste cartons and cultural paper for printing, books or newspaper produced during the manufacture process and by the offices of the plants in Taiwan were transported to the paper manufacturers in Taiwan for recycling through legal environment-friendly waste disposal service suppliers. Paper products made from 80%~100% recycled pulp and attached with the Green Mark were purchased from their downstream manufacturers to support the “Resources Recycling and Reusing Program” of the Environmental Protection Administration and achieve the goals of “recycle of wastes to displace exploitation of natural resources, full circulation of materials, and zero waste.” In 2021, 1,723,891 shipping cartons made from recycled pulp and attached with the Green Mark were purchased for the plants in Taiwan.
Recycling scrapped trays
When trays are unusable anymore after repeated use, all scrapped trays are commissioned to tray suppliers for recycling to achieve the goals of “waste to resources, replacement of natural resource exploitation, total substance recycling, and zero waste”. In 2021, 22,631 scrapped trays were recycled to reduce waste by 1.13 tons and carbon by 2.33 tCO2e.
Green Transportation
- Implementing package reduction of the R70 projector can reduce packaging materials and fuel consumption in sea transportation by about 4 kgCO2e each unit, or 1.1% carbon.
Green Design
Projectors and Visual Solution
- Constantly optimized the lighting design of projectors to save electricity of about 15.14 GWh or carbon by 7,708 tCO2e each year.
- The safe auto off function (including automatically shut off without input signals and sleep mode)
- Electricity consumption in the standard operation mode and standby mode complies with the energy-efficiency standard specified by the Environmental Protection Administration.
- Reducing the design of back-end process (electroplating, paint spraying, and printing) of products.
- Use of LED and laser eco-friendly solid-state illumination (SSI) and other mercury-free materials for a completely mercury-free projector.
- Compared to traditional short throw projectors, projectors using LED and laser SSI have a five-time longer life without the need of bulb replacement to reduce environmental protection.
Backlight Module (BLM)
- To reduce the size and materials of LGPs, meet the optical requirements, and reduce the use of optical composite films, we redesigned the INB14203 composite film of 0.26mm thick and 20 grams into the INB14211 composite film of only 0.16mm thick and 11 grams, reducing the weight each film by 45%. In 2021 we produced about 2,960 composite films to reduce weight by 26.6kg and carbon by 0.05 tCO2e.
Light Guide Plate (LGP)
- The LGP micro mechanism design was optimized to reduce product weight without sacrificing the optical design requirements. As a result, LGP thickness was reduced by 20% and weight was reduced by 30%. After the improvement of optical framework design, the original POP thickness was 0.45mm, the MOP thickness was reduced to 0.32mm, the optical performance remained unchanged, and weight was reduced by 29%. In 2021, a total of 3,213,465 pieces of 43-inch, 50-inch, and 55-inch were produced, with weight reduced by 342,257kg and carbon by 705 tCO2e.
