Acetylene gas, which is employed to create polymers such as nylon 66, polyesters, and polyethylene terephthalate (PET), as well as other plastic products, is produced using calcium carbide, which is a frequently utilized component of the process. The increasing demand for plastic products, particularly PVC, nylon 66, and polyesters, can therefore be mostly attributed to market expansion. The global annual output of plastic has grown by around 230 times, i.e. from 2 million tonnes in 1950, reaching 460 million tonnes in 2019. The worldwide production of plastics was over 390 million metric tons in 2021, with a rise of 4% annually.

Furthermore, it is anticipated that increased steel consumption across a number of industries will boost market growth. On account of its exceptional qualities, including durability and ductility, steel is mostly employed in the building and construction industry. It aids in the seismic resistance of buildings. The development of special railroads as a result of an increase in the number of high-speed trains in nations such as China, Japan, and India have increased the need for carbon steel. The need for crude steel is then anticipated to increase, propelling the calcium carbide market. Around 152 million tons (Mt) of crude steel were produced globally in September 2022, an increase of 4% from September 2021.

Growth Drivers

  • Large Number of Earthquakes Taking Place - Earth is a dynamic planet, and earthquakes are constantly occurring somewhere. The National Earthquake Information Center actually tracks approximately 13,000 earthquakes annually. Calcium carbide is used in manufacturing steel, which is further expected to be utilized in constructing buildings. Owing to the growing risk of earthquakes and floods, the need for strong construction is demanding. Hence, the demand for calcium carbide is anticipated to increase over the forecast period.

  • Growing Usage of Fertilizers - Around 200 million metric tonnes of fertilizers are anticipated to be consumed globally in 2021. By 2021, rising crop prices would result in more need for calcium cyanamide as a fertilizer, a trend that has been particularly noticeable recently.

  • Growing Oil Industry - By 2045, it is anticipated that India's oil consumption will increase to approximately 10 million barrels per day.

  • Introduction of New Technologies - CacliPro was introduced to the Russian steel industry in January 2020 by the chemicals business AlzChem Group, based in Germany. In addition to improving the castability and mechanical properties of final steel products, CalciPro is very effective at adding calcium to molten steel.

  • Rising Production of PVC- It was predicted that the quantity of PVC production would rise from 42,931 thousand tons seven years ago to 55,715 thousand tons in 2022 across the globe.

Challenges

  • Harmful Effects of Calcium Carbide on Health - Long-term exposure to calcium carbide could be damaging to a person's health. The fact that it contains phosphate and arsenic particles and produces acetylene gas when dissolved in water makes it particularly harmful when used to cure food. Arsenic and acetylene gas can affect many physiological processes and cause a variety of health problems, such as headaches, exhaustion, mood swings, seizures, and chronic hypoxia. Consequently, it is anticipated that this issue will impede market expansion.

Calcium Carbide Market Segmentation:

Application Segment Analysis

The calcium carbide market is segmented and analyzed for demand and supply by application into acetylene gas, calcium cyanamide, reducing & dehydrating agent, and desulfurizing & deoxidizing agent. The acetylene gas segment is projected to hold the highest market share. The use of this colorless gas as a fuel and a component of chemicals is widespread. A variety of industrial and commercial uses calcium carbide for the manufacture of acetylene (C2H2). In addition, there has been surging use of dissolved acetylene gas for welding, that is further expected to boost the segment’s growth in the market. It is employed as a cylinder gas for the fabrication of metal, the production of synthetic rubber, the carburization of steel, the manufacture of glass, the brazing process, as a food preservation additive, and in the building industry. For instance, in the fiscal year from April 2021 to March 2022, India consumed 0.8 million metric tons of synthetic rubber, an increment of 17% over the prior fiscal year. Furthermore, it is also used as a feedstock to make vinyl chloride and polyurethane fibers, an intermediate in the production of antiseptics, tableted pharmaceuticals, and antiseptics, as well as to make acetic acid.

End-user (Chemicals, Metallurgy, Pharmaceutical, Food)

The global calcium carbide market is also segmented and analyzed for demand and supply by the end-use industry into chemicals, metallurgy, pharmaceutical, and food. Out of these, the chemicals segment is anticipated to garner the largest revenue by the end of 2035, backed by growing investments and applications in the chemical industry. In industrial settings, calcium carbide is generally used to produce acetylene and other chemical compounds. The chemical and metallurgical sectors both use it extensively. Moreover, it is used in the vinylation of biomass feedstocks as a producer of acetylene. When CaC2 is used as the catalyst (approximately 10%), up to 39%-56% of the overall product yield is attained. In addition, by 2025, it is anticipated that investments in the Indian chemicals and petrochemicals sector would total about USD 100 billion.
