The implementation priorities of this plan include: (1) studying and analyzing the achievements of promoting zero waste, environmental and economic benefits of resource recycling at home and abroad, collecting relevant laws and regulations of resource recycling at home and abroad, and completing the research on the relevant laws and regulations of horizontal integration of resource recycling. (2) To study and analyze at least five representative industrial resources on the island, successful circular economy business models, and complete the discussion on the correlation between zero waste and waste-to-energy resource recycling after industrial transformation, and handle 3 seminars on the transformation strategy of industry-related resource recycling and zero waste, and study and propose short-term feasible implementation measures. (3) Completed 3 domestic arteriovenous industry symposiums, studied and analyzed innovative cases and models of reduction, substitution and reuse, and handled 2 domestic arteriovenous industry energy resource integration forums, and established industrial cooperation communication channels. The results of the implementation of the plan are described as follows:
Foreign regulations related to resource recycling cover a variety of aspects, including extending product life, extending producer responsibility, increasing demand for recycled materials through policies, programs, initiatives and incentives, products as a service, and establishing a shared platform to provide information disclosure and reuse channels. There are a variety of by-products in the steel industry, such as coal tar, light oil, blast furnace stone, converter stone, iron oxide powder, desulfurization stone and desulfurization stone magnetic material, etc., which are supplied to chemical, construction, civil, electrical and livelihood industries after resource processing. The steel industry's resource integration strategy includes diversification of resource sources, efficient production, energy conservation and emission reduction, circular economy and R＆D innovation. The cement industry uses sludge from wafer fabs, steel plants, water purification plants and public works as alternative raw materials to reduce the consumption, mining and purchase of natural raw materials such as limestone, clay and low alkali sand through co-processing technology. The reuse of construction waste in the cement industry can bring significant carbon reduction benefits, and the implementation of the EU carbon pricing system will also improve the economic benefits of construction waste. The process waste of the electronics industry contains more precious metal substances, and the electronics industry has high requirements for the quality of raw materials, so improving the quality of resources to reach the electronic grade is the current development direction of the waste treatment technology of the electronics industry. The development strategy of the electronics industry to achieve resource integration mainly includes supply chain optimization, R＆D innovation, energy conservation and emission reduction, and circular economy. This includes improving supply chain collaboration, reducing energy and resource consumption, and adopting environmentally friendly processes. The paper industry recycles recycled paper into environmentally friendly products, with a conversion rate and water recycling rate of more than 90%, and the waste liquid from the papermaking process can be used as biomass fuel to produce steam and electricity. The development strategy of the paper industry to achieve resource integration mainly includes circular economy, energy conservation and emission reduction, raw material diversification and R&D innovation. This includes promoting resource recycling and the use of recycled paper to reduce waste and improve resource efficiency. The textile industry uses mechanical processing technology to reconvert waste textiles into polyester fibers, and uses chemical treatment technology to recycle polyester PET bottles and waste polyester products mixed with other ingredients, such as textiles, garments, packaging materials, etc., and convert them into recycled terephthalic acid (rPTA), one of the main raw materials of polyester. The development strategy of the textile industry to achieve resource integration mainly includes green production, energy conservation and emission reduction, raw material diversification and R&D innovation. This includes reducing water and energy consumption, adopting environmentally friendly manufacturing processes, and reducing environmental impact. R&D of new technologies and high-performance textiles can help improve quality and reduce environmental impact. From the circular economy business model of the five industries, it can be found that cross-industry cooperation is the common point, the by-products or waste of one industrial process may be the resources of another industry, and the establishment of an effective cross-industry cooperation mechanism can promote resource recycling. The domestic and international steel industries are actively developing waste heat recovery technology, especially the low-temperature waste heat recovery technology "Organic Rankine Cycle", and research has pointed out that waste heat recovery in the converter stage of the steel industry has the highest technical and economic potential. However, in order to align with the trend of net-zero emissions, it is necessary to take Scenario 3 as the direction of future development. 1. Short-term (2023-2030): Under the existing manufacturing process, low-temperature waste heat recovery equipment can be added to maximize energy utilization. 2. Medium-term (2030-2040): Green hydrogen must be introduced by 2030 to gradually replace fossil fuels to cope with the high production cost pressure caused by the peak of carbon bills in 2030. 3. Long-term (2040-2050): By 2040, green hydrogen production capacity should reach more than 30% of the energy share, expand the deployment of carbon capture and storage technology, and remove a small amount of carbon emissions from fossil fuel use.
