Motor Carbon Foodprint
Motors are one of the most important source of power. According to statistics, 46.2% of energy is consumped by motors worldwide. From household appliances to industrial machinary, motors powers every equipment. What kind of material forms a motor? More than 90% is metal. Here shows TECO high efficiency (IE3) 150 hp motor data:
Steel: 54 % Iron: 32 % Copper: 6 % Aluminum: 2 % |
TECO has conducted a carbon footprint analysis of three high-efficiency motor models by "from cradle to gate" approach. Which calulated carbon emissions including raw material, manufacture process, direct manpower and waste generated. We found that 90% of carbon emissions come from the production of raw materials, and only 10% is from motor manufacture stage. This shows that the recycling of raw materials (metal parts) is important to reduce emission.
Model |
Emission from Raw Material kgCO2e |
Emission from Manufacture kgCO2e | Total Emission kgCO2e |
AEHF 2HP | 152 (92.5%) | 12 (7.5%) | 164 |
AEHF 20HP | 625 (89.9%) | 70 (10.1%) | 695 |
AEHF 150HP | 3770 (90.9%) | 375 (9.1%) | 4145 |
The total sales of TECO’s motor series of products qualifying the carbon footprint analysis accounted for 32.4% of the overall volume.
TECO conducted a carbon footprint assessment of the AEHF, AEHH, and AFHH three-model series motors. The calculation method is the proportion of the total sales volume of the model in 2023 to the total motor sales volume.
Product Stewardship
Design Stage |
Motor lightweight: The T-HiPro+ series motor is developed in 2023. The optimized design of the lightweight motor is about 25% lighter than the original product. On average, each motor can reduce weight by 3,890 kilograms and reduce carbon emissions by 9,485 kilograms. The T-HiPro+ accounts 5.7% revenue among it’s product class. |
The motor uses recycled materials: the motor casing is cast from silicon steel scraps, ferromanganese, clay, scrap steel plates and other raw materials. The 2023 cast iron casing contains 88% recycled materials. |
|
Water-based paint introduction: The motor water-based paint introduction plan was launched in 2016: By the end of 2023, the water-based paint introduction proportion has reached 81.1% of the total production, and the total emission of volatile organic compounds (VOC) has been reduced by 585,777kg, and the emission reduction has reached 72.4%. . |
|
Environmentally friendly refrigerant substitution: Home air conditioners promote R32 environmentally friendly refrigerant and process refrigerant recycling, accounting for 89% of the number of units produced in 2023. |
|
Manufacturing Stage |
Through process and equipment optimization, the overall energy saving of the Taiwan factory in 2023 will reach 1,231 kilowatt-hours. Related actions include promoting smart automated production and equipment energy-saving solutions. |
Waste resources are used to melt and reuse silicon steel scraps as motor casings. In 2023, a total of 3,419 kilograms of residual materials was recycled, with a scrap recycling ratio of 96.5%. The casting output is 3,898 kilograms. The cast iron casing contains 88% recycled materials. |
|
Controlling SF6 emissions: Overhead line switch products (POLE SW) improve measurement and filling equipment to reduce emissions, with the emissions rate reaching 1.48% in 2023 (a 47% reduction compared to 2020 emissions) |
|
Transportation Stage |
Direct logistics users shorten the delivery process and increase home delivery revenue by 637,000 in 2023. |
Use and Repair Stage |
Committed to deliver high efficiency motors. In 2023, IE3 and IE4 motors will account for 74.7% of all motor product revenue. |
Committed to the research and development of energy-saving and water-saving home appliances, green home appliances will account for 60% of revenue in 2023, with a cumulative emission reduction of 91,743 tons in three years. |
|
The development of the T-Power+ (bus) electric vehicle power system to reduce the environmental harm of fuel vehicles is a priority for the power system to obtain the DMIT (Design and Manufacture in Taiwan) Industrial Innovation Program, with a market share of 85% in Taiwan in 2023. |
|
End-of-Life Stage |
Most motor products are made of recyclable metal materials. Taking the AEHF series of motor products as an example, 88% of the materials can be recycled after the product is discarded. |
Home appliance products participate in the Taiwan Environmental Protection Agency's waste recycling policy (television sets, washing machines, refrigerators, air conditioners/heaters), providing consumers with a free service of transporting waste equipment to qualified treatment plants. Those that comply with the waste recycling policy in 2023 Home appliances accounted for 54.4% of annual sales |
|
TECO Electric and other home appliance manufacturers jointly established E&E Recycle Company in Taiwan and assigned directors to provide recycling and processing services for waste electronic and electrical items. Income from recycling in 2023 is NTD 121,648k |
|
Overall production proportion of recyclable products in 2023: 74.04%, estimated proportion of actual recycled products: 63.95% |
Hazardous Substance Policy and Material Management
Implement the management of the prohibition of environmentally harmful substances. In addition to choosing conflict-free metals as raw materials for each product design stage, a hazardous substance management mechanism is also established to clearly declare that the company, suppliers, contractors, and partners shall follow. TECO promises that by 2023, 100% of motors and home appliances and their raw materials comply with international mandatory regulations and management.
Regulatory Trends |
Restriction of Hazardous Substances in Electrical and Electronic Equipment Directive, (RoHS), Registration, Evaluation, Authorization and Restriction of Chemicals, (REACH) must be included in the management measures at least one year before implementation. |
Management Mechanism |
The production sites are all in compliance with the group's management measures for prohibiting/restricting the use of environmentally hazardous substances, and the subsidiaries and affiliated companies have consistent implementation standards as well. Raw materials, parts, processed products, and consumables must be followed. At present, 10 categories of prohibited/restricted hazardous substances are controlled, covering non-steel, steel, plastic packaging, paper packaging, wood packaging, foam packaging and process chemicals. |
Renew and Implementation |
When there is a major change in the external norms, it will be discussed across business departments and re-promulgated. The frequency is about once a year. |
Disclosure |
All business groups follow TECO policy, and fully control 10 categories of prohibited/restricted hazardous substances. |
