This program aggregates the carbon management results of the recycling industry (410 notifications of The Regulated Recyclable Waste Recycling and Disposal Enterprises, and 21 notifications of The Public or Private Waste Clearance and Disposal Organizations) from the sub-programs. Regularization, carbon management analysis, and data quality analysis were performed. The total carbon emissions from the resource recycling industry were 201,344.26 metric tons of CO2e, of which 113,346.88 metric tons of CO2e were announced as the total carbon emissions from Regulated Recyclable Waste Recycling and Disposal Enterprises, with purchased electricity accounting for the highest share of the total carbon emissions (50.30%), followed by mobile sources (28.57%), and stationary fuel combustion sources (30.55%). The total carbon emissions of Public or Private Waste Clearance and Disposal Organizations were 87,997.38 t CO2e, with stationary fuel combustion sources accounting for the highest carbon emissions (65.35%), followed by mobile sources (18.77%) and purchased electricity (15.68%).
In terms of data quality management error levels, out of the 431 carbon management results, 317 companies were rated at level 2, 107 at level 3, and 7 were not rated due to no business activities or being used solely as storage sites (resulting in zero carbon emissions).
To comprehensively understand high-carbon emission industries within the resource recycling sector, this year's plan uses the recycling registration processing industry as an illustrative example for quantitative analysis. The results highlight waste lighting sources with the highest carbon emissions at 348.83 kilograms of CO2e, followed by waste lead batteries, waste dry batteries, and waste plastic containers in descending order. This analysis helps identify industries with elevated carbon emissions based on materials, facilitating prioritization for low-carbon counseling in high-emission sectors.
This project has successfully assessed the current state of industrial technology development in Taiwan's resource recycling sector, specifically focusing on waste tires, waste paper containers, and waste glass containers. Additionally, it has evaluated low-carbon technologies in the international resource recycling industry. Literature has been collected from Europe (Poland, Austria, the United Kingdom, Denmark, and Sweden), the Americas (the U.S.), and Asia (South Korea and China). The project aims to provide low-carbon technology recommendations for Taiwan's resource recycling industry, with a focus on process optimization, end-product improvement, management enhancement, and category management. Furthermore, the project offers suggestions for developing corresponding technologies based on the different materials to be processed.
This report elaborates on the automation, intelligence, and low carbonization aspects of the resource recycling industry. In the current year, our initial focus was on materials with high carbon emissions that should be registered in the recycling and processing industry. We screened these materials based on the quantity leaving the factory and the number of manufacturers. Two briefing sessions were conducted on September 25 and 26, 2023. Subsequently, three materials and four manufacturers were selected for on-site surveys and deployment.
The deployment of 102 power sensors was completed on August 25, October 24, and November 1, 2023, respectively. Three expert on-site counseling sessions occurred on October 20 and December 14, 2023. After analyzing the results and recommending improvements, an effective reduction of up to 10% in energy usage rate is achievable. Estimated carbon reduction is about 21 metric tons per year, accompanied by an improvement of up to 8% in process efficiency. Moreover, future evaluation of installing power sensors in low-energy or stabilized power equipment is recommended, as the low power consumption of such equipment eliminates the need for additional meters.
This report has also completed an inventory of the power generation potential of green energy installations. We reached out to four industry players and completed an assessment, determining a buildable capacity of approximately 480(kw). The annual carbon reduction benefit of solar green energy installations in the resource recycling industry has increased from 9,619.78 metric tons of CO2e in the past to 11,540.29 metric tons of CO2e, including those currently under construction. This is equivalent to the carbon adsorption capacity of 29.8 Daan Forest Parks.
The program has developed product life cycle flow charts for WEEE and WISE, established rules for carbon footprint product categories, and completed carbon footprint updates for 10 types of recycled materials. The updated carbon footprint shows a 15% to 32% reduction in carbon emissions compared to the data surveyed 10 years ago. This reduction is attributed to the decreased energy coefficient of Taiwan's power companies over the years.
It's calculated that if recycled materials replace virgin materials in 2022, it could lead to a reduction of 1,390,037 tons in carbon dioxide emissions. Environmental footprint calculations reveal that over 98% of environmental impacts stem from the manufacturing stage, primarily due to higher energy and resource consumption. Therefore, to reduce the future carbon or environmental footprint of recycled scrap iron, a priority should be placed on improving the manufacturing stage. Enhancing energy efficiency and product yields will be instrumental in mitigating the environmental impact of the manufacturing process.
The project hosted the "2023 Carbon Reduction Technical Seminar for the Resource and Recycling Industry" on November 27 and November 28, 2023. The event attracted approximately 270 participants over the two days, and it received coverage from 8 newspapers and 1 TV platform, thereby enhancing the visibility of carbon reduction efforts in the resource and recycling industry. Furthermore, on December 12 and December 13, 2023, two presentations on achievements and two presentations on technology transfer were successfully conducted, with a total of 126 participants.
