"3060" double carbon target has been widely concerned since it was put forward, but also put forward new requirements for the development of all walks of life. As an enterprise, it is not only the main body of carbon emissions, but also the main force to achieve carbon neutrality. This is especially important for the building materials industry, which is closely related to People's Daily lives.

The government and relevant associations have been paying attention to carbon reduction in the building materials industry. The Ministry of Industry and Information Technology said that it would speed up the implementation of carbon peaking in the industrial sector, and jointly formulate the implementation plan of carbon peaking in key industries such as non-ferrous metals, building materials, steel and petrochemicals. The commission has set up a working group on statistical accounting of carbon emissions, including the Association of Building Materials Industry. China Building Materials Federation deliberated and passed the Promotion Committee of Carbon Peaking and carbon Neutrality in the Building materials Industry, proposing to comprehensively improve the green and low-carbon development level of the building materials industry.

Statistics from the China Association of Building Energy Efficiency show that the total carbon emission of the whole building process in China accounts for 51.2% of the total carbon emission of the whole country, which runs through the whole life cycle of the building: production and transportation of building materials, construction, construction operation/maintenance/scrap and demolition, etc.

This also clearly points out the direction for the carbon reduction actions of building materials enterprises: under the multi-pronged approach in the fields of production, construction and construction operation, double domain coverage inside and outside the factory can be achieved.

Factory production, the whole chain of carbon reduction is promising

In early September last year, the Ministry of Ecology and Environment issued the Notice on Promoting the Work Related to Peaking carbon Neutrality in National Eco-Industrial Demonstration Parks, which clearly required each park to carry out technological and management innovation to achieve energy conservation and emission reduction in the production process.

The production process in a broad sense includes materials, processing, storage, transportation and other links, among which the supply of high-quality raw materials, automatic workshop production, intelligent storage and logistics greatly reduce the carbon emissions caused by the production process, is an indispensable link in the carbon neutral chain, and is also a necessary topic for production enterprises to reduce carbon action.

As a service provider of building materials system, Oriental Yuhong has already experienced mature operation of carbon reduction chain. We have established long-term friendly cooperative relations with high-quality suppliers such as Sinopec, petrochina, BASF, Lanxess and Dow. With the introduction of advanced production equipment such as American R&D, Italian Boato and German Kraussmaffei TPO, the company innovates and develops its own technology, equipment and system control program to create "unmanned workshop" and "black light workshop".

Visualization and remote monitoring are another highlight of the carbon reduction chain. A "code" in hand, to achieve the production process forward and reverse full traceability; Automatic transmission of quality control system data to improve product quality; Real-time monitoring of equipment operation to improve utilization.

In addition, in the intelligent storage system built, the three-dimensional storage shelves, tunnel stacker, shuttle car system, automatic warehousing and delivery system, automatic control system, information identification system, computer monitoring system, etc. cooperate to realize the automatic processing of the whole process from automatic labeling of the production line, automatic code scanning into the warehouse to automatic delivery of finished products, automatic vehicle number calling, automatic tracking of vehicle logistics.

Construction site, man-machine cooperation to reduce carbon efficiency

The Ministry of Housing and Urban-Rural Development and 13 other departments jointly issued the Guiding Opinions on Promoting the Coordinated Development of Intelligent Construction and Building Industrialization, making it clear that the application of intelligent construction in all aspects of engineering construction should be increased by vigorously developing building industry as the carrier and digitization and intelligent upgrading as the driving force.

Compared with the relatively concentrated workshop production mode of the manufacturing industry, the building materials industry focuses on on-site construction outside the factory. The combination of skilled craftsmen and intelligent machinery can better create a "smart site", through fine construction to reduce the waste of raw materials, reduce environmental pollution.

In 2011, Oriental Yuhong took the lead in proposing a standardized construction management system for the building waterproof industry. Through a series of measures including the integration of construction team construction, safe production, standardized construction and scientific management, it has realized a standardized construction site with "training specialization, process standardization, process standardization, image standardization, equipment modernization and safety normalization".

The use of smart construction equipment is also pre-emptive. As early as 2007, the first domestic mechanical roll spreading machine was developed, marking the railway bridge waterproofing has taken a new step in the field of fully automatic mechanized construction work. Intelligent products such as "Hongren", "Honghong" and "Hongcyclone" have been successively launched, which save energy, reduce carbon efficiency and are widely praised by the industry.

Building Operation- Longevity building is imperative

Data from the survey showed that carbon emissions from building operations accounted for 21.9 percent of the country's total carbon emissions. Including the construction operation, future maintenance, scrap demolition and other aspects. In particular, short-lived buildings have caused a huge waste of resources. For example, 15 buildings in a community in Kunming were finally exploded because no one maintained them and their foundations were immersed in water for a long time, which caused safety risks. This loud noise also brought more reflection to the industry.

Qiu Baoxing, former vice Minister of Housing and Urban-Rural Development, once pointed out that the extension of building life, waste utilization and water recycling are crucial to the green and low-carbon development of cities. Experts from China Building Standard Design and Research Institute have also mentioned that the longevity of buildings is the biggest emission reduction.

Of course, with the progress of technology, steel/cement and other hard materials upgrade, the building quality and life has been greatly improved, and high-performance waterproof materials, thermal insulation materials, roof system and so on are also constantly applied to the main body of the building, so that the building performance has been improved, for example, the thermal insulation quality upgrade has significantly reduced the winter heat loss.

Oriental Yuhong knows the importance of building materials for a building, and provides high-quality products for civil and engineering buildings in many fields, such as waterproof, thermal insulation and coating, so as to reduce the probability of "architectural chronic disease". Its brand "Huasha" is committed to providing green special mortar for buildings; The building energy saving system created by "Wolniushan Energy Saving" has been successfully applied in hundreds of large construction projects across the country; Building repair adhering to the professional "treatment", to help improve the life of the building, to avoid the waste of raw materials caused by large-scale demolition and construction.

Carbon neutrality has now accelerated. Especially under the guidance of "Action Plan for Digital Transformation of Intelligent Manufacturing in Building Materials Industry (2021-2023)" issued by the Ministry of Industry and Information Technology, the digital, networked and intelligent level of building materials industry will also be greatly improved. Relevant industries are also running to reduce carbon. We also look forward to the action of the whole industry to make more contributions to achieve the goal of carbon neutrality.

“3060”双碳目标自提出以来广受关注，也对各行各业发展提出了新要求。作为企业，既是碳排放主体，更是实现碳中和的主力军。对与民众日常生活息息相关的建材行业而言，这一使命尤为重大。

政府及相关协会一直在关注建材行业减碳：工信部表示将加快实施工业领域碳达峰行动，会同有关部门制定有色金属、建材、钢铁、石化等重点行业碳达峰实施方案；发改委成立包括建材行业协会在内的碳排放统计核算工作组；中国建筑材料联合会审议通过建材行业碳达峰、碳中和工作推进委员会，提出要全面提升建材行业绿色低碳发展水平。

中国建筑节能协会统计数据显示，全国建筑全过程碳排放总量占全国碳排放总量比重达51.2%，贯穿建筑全生命周期：建筑材料生产和运输、建筑建造、建筑投入运行/维护/报废拆除等。

这也清晰为建筑建材企业减碳行动指明了方向：在生产、施工、建筑运行领域多管齐下，实现厂内厂外的双域覆盖。

工厂生产，全链减碳大有可为

生态环境部去年9月初下发的《关于推进国家生态工业示范园区碳达峰碳中和相关工作的通知》，明确要求各园区要开展技术革新、管理创新，实现生产过程节能减排。

广义的生产过程包含材料、加工、仓储、运输等多个环节，这其中的优质原料供应、自动化车间生产、智能化仓储物流等极大降低了生产过程导致的碳排放，是碳中和链条上不可缺少的一环，也是生产型企业减碳行动的必选题。

作为建筑建材系统服务商的东方雨虹，减碳链早已成熟运转。与中石化、中石油、巴斯夫、朗盛、陶氏等优质供应商建立了长期友好合作关系；引入美国R&D、意大利Boato、德国克劳斯玛菲TPO等先进生产设备的同时，创新开发出适应自身的技术、装备、系统控制程序，打造“无人车间”、“黑灯车间”。

可视化与远程监控是减碳链上的另一大亮点。一“码”在手，实现生产过程正向和逆向全追溯；质检系统数据自动传递，提升产品质量；实时监测设备运转情况，提升使用率。

此外，搭建的智能仓储系统中，立体库货架、巷道堆垛机、穿梭车系统、自动出入库输送系统、自动控制系统、信息识别系统、计算机监控系统等通力合作，实现从生产线自动贴标签、自动扫码入库到成品自动出库、车辆自动叫号、车辆物流自动跟踪的全过程自动化处理。

施工现场，人机协作降碳增效

住建部等13部门联合印发《关于推动智能建造与建筑工业化协同发展的指导意见》，明确要以大力发展建筑工业化为载体，以数字化、智能化升级为动力，加大智能建造在工程建设各环节应用。

与制造业相对集中的车间化生产模式相比，建筑建材行业侧重厂外的现场施工。能工巧匠和智能机械合力才能更好打造“智慧工地”，通过精细化施工减少原料浪费、降低环境污染。

2011年东方雨虹率先提出建筑防水行业标准化施工管理体系，通过整合施工队伍建设、安全生产、规范施工、科学管理等系列举措，实现了“培训专业化、流程标准化、工艺标准化、形象标准化、装备现代化、安全常态化”的标准化施工现场。

智能施工设备运用同样先发制人。早在2007研制出国内首款机械卷材展铺机，标志我国铁路桥梁防水在实现全自动机械化施工作业领域迈出了崭新的一步，陆续推出的“虹人”“虹象”“虹旋风”等智能化系列产品，节能节力降碳增效，广受行业好评。

建筑运行-长寿建筑势在必行

调查数据显示，建筑运行碳排放占国家总碳排放的21.9%。其中包含了建筑投入运行、未来维护、报废拆除等多个方面。尤其是短命建筑带来巨大的资源浪费，比如昆明某小区15栋大楼因无人维护，基础长期浸泡水中存在安全隐患，最终被集中爆破，这一声巨响也给行业带来了更多反思。

前住建部副部长仇保兴曾指出：建筑寿命的延长、垃圾利用、水循环利用等对城市向绿色低碳发展至关重要；中国建筑标准设计研究院专家亦曾提到：建筑的长寿是最大的减排。

当然随着技术进步、钢筋/水泥等硬材料的升级，建筑质量和寿命得到了很大提高，并且高性能防水材料、保温材料、屋顶系统等也不断应用于建筑主体，让建筑性能得到了改善，比如保温品质升级大幅减少了冬季热能损。

东方雨虹深知建材之于一座建筑的重要性，在防水、保温、涂料等多个领域为民用、工程建筑提供优质产品，降低“建筑慢性病”概率；旗下品牌“华砂”致力于为建筑提供绿色环保的特种砂浆；“卧牛山节能”打造的建筑节能系统已成功应用于全国数百项大型建筑工程；建筑修缮秉承专业“医治”，帮助提升建筑寿命，避免大拆大建导致的原材料浪费。

碳中和目前已经加速前行。尤其在工信部《建材工业智能制造数字转型行动计划（2021-2023年）》指导下，建材行业数字化、网络化、智能化水平也将大幅提升，相关行业更是纷纷跑步加入减碳降碳，也期待全行业的行动能够更为碳中和目标达成贡献更多力量。
