Aluminium, the second most utilised metal worldwide, holds diverse and foundational applications, from electrical transmission to defence and construction. Notably, aluminium is a crucial input in manufacturing goods that contribute to emissions reduction, such as electric vehicles and energy-efficient buildings. This dual role underscores the significance of decarbonising aluminium, as it can positively influence industries pivotal to global climate efforts.
As the repercussions of climate change intensify, nations and industries are actively exploring innovative approaches to decarbonise, aiming to meet emissions targets, mitigate the risk of carbon border tariffs, and alleviate energy costs. Industrial energy consumption is the primary contributor to global greenhouse gas (GHG) emissions. Therefore, achieving decarbonisation in heavy industry holds the potential for a direct and immediate impact on reducing GHG emissions and mitigating the pace of climate change.
This ongoing transformation instils a cascade of essential modifications in product development practices, technological advancements, and the ultimate utilisation of materials. Amongst various metals, aluminium is anticipated to emerge as a linchpin in this transformative journey, playing a pivotal role in redefining processes and applications to align with sustainability and environmental responsibility objectives. Regarding aluminium, China dominates the global market, accounting for approximately 60 per cent of primary aluminium production and consumption. The Chinese government and other nations are employing policy measures to influence the decarbonisation initiatives within industries.
Below is a list of top 5 sustainable initiatives carried out in China:
Gränges and Shandong Innovation Metal (group) Technology are collaborating to establish a recycling and casting facility in the hydro-power-rich region of Yunnan, China. The joint venture has successfully secured access to environmentally friendly primary aluminium, obtained through energy-efficient methods at a nearby smelter, and will utilize renewable energy for the casting operations. To reach its 2040 net-zero goal, Gränges' carbon footprint will be significantly reduced thanks to this strategic alliance. Additionally, it will make it possible for Gränges to satisfy Asian customers' requests for industry-leading sustainable aluminium solutions.
As per Jörgen Rosengren, the CEO of Gränges, in alignment with the Navigate plan for sustainable growth, teaming up with SIG represents a crucial stride. This collaboration positions Gränges to achieve climate neutrality by 2040, amplifying the company's commitment to sourcing metal and energy through sustainable means. The escalating demand for eco-friendly aluminium solutions in Asia underscores the significance of this partnership, enhancing the competitive edge and allowing them to deliver greater value to our customers.
China's Henan Yongheng Technology Co., Ltd. initiated an ambitious endeavour on November 17 to develop a novel environmentally friendly aluminium alloy with an annual production capacity of 500,000 tonnes. With a total investment of RMB 3.5 billion, the expansive project will cover 340 acres. The company's strategy involves establishing a standardized plant spanning 200,000 square meters, housing cutting-edge facilities such as a state-of-the-art green aluminium alloy production line, and using digitally intelligent aluminium processing and production equipment.
Chinalco Group's "Baotou Aluminum Industrial Park Green Power Supply Project" and "Baotou Aluminum Coal-fired Power Plant Renewable Energy Alternative Project" have earned spots on the market-oriented new energy projects roster. The official grant for these two latest energy projects is set to support Baotou Aluminum's "green aluminium road" journey, as it will ramp up the pace of green, low-carbon and high-quality raw material production. Furthermore, implementing these initiatives will reduce annual carbon dioxide emissions by 5.96 million tonnes. This lays the groundwork for Baotou Aluminum to embrace sustainable, green, low-carbon, and high-quality development and serves as a catalyst for cultivating new momentum and enhancing competitive measures.
These approved projects boast a combined installed capacity of 2.1 million kilowatts, with 1.9 million kilowatts generated from wind power and 200,000 kilowatts from photovoltaic sources. Upon project completion, the peaking capacity of the Baotou thermal power plant and the electrolytic aluminium load absorption capacity will be harnessed to integrate new energy deeply. This strategic approach is anticipated to elevate the company's green electricity proportion to over 40 per cent.
State Power Investment Aluminum and Power Company, in collaboration with Fujian Company, Wuling Power, and Zhongwei New Energy Company, completed the construction of the first electrolytic aluminium industry in Ningxia, China. This milestone involved establishing two electrolytic aluminium units, Qingtongxia Branch and Ningdong Branch, resulting in a substantial green power transaction totalling 9 million kWh.
This green electricity transaction not only positively impacts the environment but also significantly reduces carbon dioxide emissions, sulfur dioxide, and nitrogen oxides by 8,106.3 tonnes, 4.23 tonnes, and 3.87 tonnes, respectively, for the electrolytic aluminium companies. Furthermore, it establishes a reliable and transparent avenue for obtaining green electricity within the electrolytic aluminium industry.
As a trailblazer in green power trading within Ningxia, Aluminum Electricity Co., Ltd. took the proactive approach of sourcing green power from new energy companies for the two electrolytic aluminium units. While engaging with several new energy companies during the negotiation process, final cooperation agreements were secured with Fujian, Wuling Electric Power, and Zhongwei New Energy Company.
On December 5th, Chinalco Zhengzhou Enterprise and Henan Tianchen Xinyuan Environmental Protection Technology Research Institute Co., Ltd. solidified their commitment to advancing sustainable and eco-friendly energy solutions by signing a strategic framework and a cooperation agreement on new green energy supply technology and equipment. This collaboration marks a significant stride towards fostering environmentally responsible practices.
The agreement underscores a joint approach to promotion and critical follow-up, reflecting the shared dedication of the two Chinese companies. Capitalizing on Great Wall Aluminum's expertise in research and development, design, and information within equipment manufacturing, coupled with Tianchen Xinyuan's strengths in technological innovation, research and development, and operational excellence in environmental protection, the partnership aims to propel forward new technologies in environmental protection, with a specific focus on urban mining and resource recycling.
Chinalco's overarching objective is to integrate the environmental protection equipment manufacturing industry with a keen emphasis on reducing carbon emissions, conserving energy, and cutting operational costs. The conglomerate is poised to address comprehensively the environmental challenges stemming from solid waste, sewage, waste gas, noise, and other concerns associated with Chinalco Zhengzhou's production and operational activities.
