West China Cement Limited (the "Company") and its subsidiaries (collectively, the "Group") is one of the leading cement producers in Shaanxi Province, with a leading market position in eastern and southern Shaanxi and a presence in Xinjiang and Guizhou Provinces as well as Mozambique, Africa. As at 31 December 2020, the Group had a total production capacity of 33.2 million tons, comprised of 22 NSP cement production lines, with 23.3 million tons in Shaanxi Province, 6.1 million tons in Xinjiang Province, 1.8 million tons in Guizhou Province and 2.0 million tons in Mozambique, Africa. Moreover, the Group had total production capacities of 15.1 million tons of aggregates and 9.80 million cubic meters of commercial concrete.
The Group's cement production is geared towards the economic development of Western China, driven by the Chinese Government's "Western Development Policy" and the "Silk Road Economic Development Plan". The Group aims to serve the development needs of Shaanxi, Xinjiang, Guizhou and Western China, supplying cement products to the infrastructure, urban and rural construction markets. The Group's cement products are used in a variety of infrastructure projects such as highways, railways, bridges, hydroelectric power stations, water conservancy and water transfer projects. The Group also focuses on serving both the urban and rural development needs of western China, an area which is experiencing rapid urbanisation and population resettlement, accompanied by housing and social infrastructure development.
The Group focuses on strengthening its position in its core markets of Eastern and Southern Shaanxi Province, where it has constructed or acquired well-positioned plants. This has resulted in the Group enjoying a leading market position in Shaanxi Province and benefiting from barriers to entry caused by high transportation costs. The Group has maintained a strong market position in its Southern Shaanxi core markets, where high levels of market share coupled with good infrastructure demand have resulted in continued average selling price ("ASPs") premiums and more stable margins. ASPs in Central Shaanxi have been increasing in recent years even under the continuing low demand scenario through the continuation of occasional peak-shifting production halts during low season periods under the stringent environmental policy. However, due to the impact of the coronavirus disease 2019 ("COVID-19") outbreak, the ASPs in Southern Shaanxi, Central Shaanxi, Guizhou and Xinjiang decreased. Fortunately, the Group has continued to implement efficiency enhancements and cost-cutting measures and has been able to maintain a decreasing cost in 2020. Taken together, these have contributed to the Group's stable margins in 2020 even under the impact of COVID-19.
Energy conservation and emission controls are increasingly important factors in the cement industry and the Group continues to work towards best of industry standards in these areas. All of the Group's production facilities are NSP lines, mostly situated in close proximity to limestone quarries and the Group uses conveyor belts at many of its plants in order to minimise transportation related emissions. The Group has constructed heat-recycling plants at over 80% of its production capacity, reducing approximately 30% of electricity consumption and decreasing CO2 emissions by approximately 22,000 tons per year per million tons of production.
All of the Group's plants in Shaanxi, Xinjiang and Guizhou Provinces have been installed with denitration (De-NOx) equipment, reducing nitrous oxide emissions by approximately 60% per ton of clinker produced, as well as Particulate Matter (PM) reduction equipment. The Group is also involved in hazardous and municipal waste incineration through Yaobai Environmental.
