资源增效节能降本 内蒙古阿拉善地区天然碱矿储量丰富，为生产纯碱创造了条件，但是该地区的水资源较为稀缺，如何实 现节水是生产控制的关键。通过一系列探索，内蒙古博源银根化工有限公司找到了"解渴"妙招：在制碱 过程的冷却环节，该公司以"空冷替代水冷"的思路构建了全流程空冷节水系统，配置多套空冷器，成功 实现节水节能。 广东南方碱业有限公司则"变废为宝"。该公司战略发展部部长冯伟东提到，他们引进高压隔膜压滤机， 不仅能高效产出低氯白泥浆，让白泥实现资源化再利用，还能大幅减少固废排放。 瞄准纯碱生产的冷却环节，瀚能(苏州)节能科技有限公司针对不同地区的水质差异，对纯碱冷却设备进 行了差异化设计，让不同水质都能有对应设备，且设备耐高温、耐腐蚀，余热回收效率达90%以上。 Solex中国服务中心董事、副总经理张厚清则介绍了Solex冷却技术，他们利用整体一致的密相输送技术 确保产品颗粒被均匀冷却或加热，采用传热板间接热传导换热以冷却物料，实现资源节约。 面对原料成本攀升、传统制碱方法利润微薄、环保治理压力增大、能源消耗高等难题，纯碱行业如何突 破发展瓶颈?近日在江苏无锡召开的2025年纯碱技术年会上，与会专家指出，资源合理 ...

Core Viewpoint - The Henan Provincial Department of Natural Resources has issued detailed implementation rules to enhance ecological restoration incentives while strictly regulating the use of stone and soil materials, aiming to prevent illegal mining under the guise of restoration [1][2]. Group 1: Project Approval and Regulation - The new rules establish a negative list for project approval, prohibiting the packaging of construction, mineral resource development, and coalfield fire hazard management as ecological restoration projects [1]. - Existing mining land intended for development will not have restoration projects set up and must follow construction project approval procedures [1]. - Projects involving the sale of sand and gravel must comply with regulations for construction projects [1]. Group 2: Utilization of Stone and Soil Materials - The rules impose strict constraints on excavation activities, stating that no new excavations are allowed in restoration areas, and existing pits cannot be deepened [1]. - Any necessary slope reduction must be evaluated by qualified geological disaster prevention units [1]. - Remaining stone and soil materials must undergo asset evaluation and government pricing before being publicly sold, with all proceeds going to the treasury [1]. Group 3: Approval and Incentive Measures - The rules eliminate the need for separate soil and stone utilization plans for restoration projects, integrating these into the ecological restoration plan [2]. - Restoration plans involving the sale of stone materials must be reviewed by local natural resource departments and approved by county-level governments [2]. - The rules encourage the use of mining solid waste for soil improvement and allow for the re-establishment of mining rights for eligible abandoned mines [2]. Group 4: Accountability and Oversight - A three-tiered regulatory system is established to address illegal mining and improper disposal of stone materials, with measures including rectification orders and criminal liability [2]. - The rules promote the establishment of integrity archives and the implementation of credit penalties for violations [2].

Core Viewpoint - The use of corn as fuel by barbecue restaurants has sparked controversy, highlighting public sensitivity towards food security and resource allocation [1][2][3] Group 1: Industry Practices - A barbecue restaurant in Yantai, Shandong, claims to use corn as fuel, stating that some corn is sourced from local farmers, which they believe helps farmers rather than wasting resources [1] - Similar practices have been reported in other regions, such as a restaurant in Shenyang, Liaoning, which also used corn for grilling, indicating a trend in the industry [1] - The restaurant's management argues that using corn results in a softer fire and less smoke, enhancing the flavor of the meat, and they assert that the price paid for corn is not below market rates [2] Group 2: Policy and Regulation - National policies have shifted from promoting the moderate development of corn-based fuel ethanol to strictly controlling its use, as outlined in the 2022 Central Document No. 1 [2] - This policy change aims to balance corn production and sales while ensuring food security, reflecting a broader regulatory approach to the industrial use of corn [2] Group 3: Public Sentiment and Ethical Considerations - The traditional view holds that food should be used in ways that align with social ethics, and using corn as fuel may contradict values of resource conservation and respect for nature [3] - Public reactions to such practices indicate a strong concern for the rational use of resources and food security, suggesting that any potential waste should be approached with caution [3] - The controversy surrounding the use of corn as fuel could prompt a reevaluation of the diverse values and sustainable utilization paths for food resources [3]
