听着他的话，我又多了一份放心。 "我"曾是一片夯土老藏房的一部分，身上烙印着阳光、风雨和酥油茶的味道。随着老城区改造，在推土 机的轰鸣中破碎、沉睡，等着与其他钢筋、木材一同被遗弃，成为人们口中的"建筑垃圾"。 就在我以为生命即将终结时，被一辆卡车运走，沿途的风裹着雪山的清冽向我吹来，阳光也格外耀眼。 最后，我和其他朋友一起到了达孜区岗日霓霞建筑垃圾收回制砖厂。 机器轰鸣，全副武装的工人先将我们集中起来——来自老城区民居上的旧窗棂、堆龙德庆区某商场改造 时破损的瓷砖、尼木县公路升级铲下来的水泥块…… "这些废旧材料都是从各个建筑工地送来的，不需要我们购买，可都是好'宝贝'啊。既解决了建筑垃圾 无处去的问题，又能带动咱们群众增收，实现了节能环保与资源再利用的双重利益。"这是我第一次听 到老板格桑次仁的声音。在他的肯定中，我的重生之旅就此开始了。 随后，我们被送上长长的传送带，等待粉碎、磁选、筛分。很快，我们褪去了旧日形态，反而倍感轻 松。 "这些分离出来的木屑，也没啥用，怎么处理？"我听到有人发问。 "谁说没用？都是柴火，去周边村里问问，谁家需要，免费拉走。"格桑次仁说，"我们要实现资源再利 用的最大化。" 很快 ...

这将使家电再生材料的使用有据可依，促进家电行业资源再利用率的提升。 标准提出三方面要求，首先是材料选择兼顾性能与环保。标准要求再生材料应满足家电产品设计及使用要求，关键零部件用再生材料制品应通过验证试验， 以证实其可靠性等同于原生材料制品。同时，在保障产品性能和质量的前提下，优先选用来源广、易回收处理且环境友好的再生材料，减少对环境的负面影 响。 其次是构建全链条质量管控与追溯机制。标准要求家电制造企业、制品制件企业及再生材料企业之间建立协同追溯机制，强化再生材料在整个使用过程中的 管控并做好详细信息记录，采购记录、生产记录、检验报告、销售凭证等所有溯源文件至少要保存5年，保障再生材料信息在采购、生产、销售等各环节的 可获取性与可追溯性。 第三是明确使用率计算方法和分级判定原则。标准统一了家电产品消费后再生材料使用率的计算方法，使不同企业、不同产品之间消费后再生材料使用率数 据具有可比性。同时，标准采用"消费后再生材料使用率"与"消费后再生塑料使用率"双指标进行分级判定，将产品划分为A、A+、A++三个等级，有利于引 导行业绿色转型。 上述废旧家电回收处理企业负责人向记者分析认为，以前废旧家电回收处理得到的材 ...

Core Viewpoint - The company is advancing towards a green development path by implementing a near-zero discharge system for industrial wastewater and enhancing the comprehensive utilization rate of industrial solid waste from 28% in 2020 to a projected 53% by 2024, with plans to exceed 60% by the end of the 14th Five-Year Plan [1][2]. Group 1 - The company has established a leading industrial wastewater near-zero discharge system, utilizing a three-tier process of wastewater treatment, reuse, and regeneration [1]. - The comprehensive utilization rate of industrial solid waste has significantly increased, with a target of over 60% by the end of the 14th Five-Year Plan [1]. - In 2023, the company has integrated industrial solid waste management into ecological protection actions, launching 22 demonstration projects with an additional annual processing capacity of 21.9 million tons [1]. Group 2 - The company is focusing on building a green industrial chain for resource reuse, targeting areas such as mine filling, construction materials, high-value utilization, and cross-industry linkages [2]. - A pilot project for the collaborative remediation of geological environments using industrial solid waste has been initiated, in partnership with the Chinese Academy of Sciences [2]. - The company is also working with research institutions to establish technical standards for the use of coal-based solid waste in saline-alkali and desertified lands [2].

Core Viewpoint - The article emphasizes the necessity for chemical companies to implement energy-saving and carbon-reduction actions in response to the "2024-2025 Energy Saving and Carbon Reduction Action Plan," highlighting New Yangfeng's innovative strategies to achieve these goals. Group 1: Technological Innovation - New Yangfeng has invested 1.73 billion yuan in upgrading its ammonia synthesis plant by introducing advanced water-coal slurry gasification technology, which fundamentally changes the traditional high-energy consumption model of ammonia synthesis. After the project launch, the electricity consumption per ton of ammonia decreased from 1,650 kWh to 400 kWh, while production capacity increased threefold, achieving a breakthrough of "increased production without increased carbon" [1]. Group 2: Resource Reutilization - New Yangfeng has innovatively utilized phosphogypsum, a byproduct of the phosphorus chemical industry, by transforming it into various applications such as roadbed materials and building gypsum boards, which replace traditional high-carbon footprint materials. This approach not only mitigates the environmental risks associated with phosphogypsum storage but also contributes to indirect carbon reduction [2]. Group 3: Digital Empowerment - The company emphasizes the importance of digitalization in accurately calculating and controlling carbon emissions. By developing self-control technology in the sulfuric acid roasting process, New Yangfeng has optimized production parameters, reducing temperature fluctuations from ±15°C to ±2.5°C. This enhancement leads to more efficient raw material combustion, reducing sulfur dioxide emissions and lowering raw material and energy consumption [3].

Core Viewpoint - The article discusses the challenges and solutions related to the "second number renewal" service, which aims to provide users with a "clean" mobile number free from previous ownership issues, highlighting the need for better coordination between telecom operators and internet platforms [5][12][14]. Group 1: User Experience and Issues - Many users face difficulties when trying to register new mobile numbers, as these numbers may have been previously active and linked to other accounts, leading to a "digital identity crisis" [3][5]. - The Ministry of Industry and Information Technology (MIIT) reported that by May 2025, the total number of mobile phone users in China is expected to reach 1.807 billion, intensifying the competition for number resources and prompting operators to recycle idle numbers [4]. - The "second number renewal" service, launched in May, allows users to unlink historical internet accounts from their new numbers, covering over 200 mainstream applications [5][12]. Group 2: Operational Challenges - The current "renewal" service primarily involves a one-way request from operators to internet platforms, leading to a lack of transparency and understanding of the processing results for users [7][9]. - Issues such as unstandardized processes and data interoperability hinder the effectiveness of the "second number renewal" service, raising questions about accountability among telecom operators and internet platforms [8][9]. Group 3: Recommendations for Improvement - Telecom operators should establish a rapid response mechanism to enhance service efficiency and transparency, ensuring users can track the progress of their requests [10][11]. - Internet platforms are encouraged to take responsibility for timely responses and efficient processing of unlinking requests, improving communication with telecom operators to streamline the process [11][12]. - Users should be empowered to authorize operators and platforms to handle unlinking matters, creating clear boundaries of responsibility to protect data and ensure compliance [12][13].
