2010 to 2015

From 2010 to 2015, the calcium hydroxide market experienced increased demand, driven by infrastructure development and stricter environmental regulations. The construction boom in emerging economies, particularly in Asia, led to higher consumption of calcium hydroxide. Additionally, the adoption of more stringent water treatment standards globally increased demand from municipal and industrial water treatment facilities. Prices during this period ranged from $150 to $200 per metric ton.

2015 to 2020

Between 2015 and 2020, the calcium hydroxide market saw further growth. The compound’s use in flue gas desulfurization (FGD) to reduce sulfur dioxide emissions from power plants and industrial facilities became more widespread, driven by environmental regulations. Moreover, the agriculture sector’s demand for calcium hydroxide as a soil amendment and pesticide increased. Prices during this period fluctuated between $200 and $250 per metric ton, reflecting these growing demands.

Recent Trends

Impact of COVID-19

The COVID-19 pandemic in early 2020 had significant impacts on the global economy, including the calcium hydroxide market. The initial phase of the pandemic led to disruptions in supply chains and a slowdown in industrial activities. Construction projects were delayed or halted, and water treatment facilities faced operational challenges. As a result, the demand for calcium hydroxide decreased, causing prices to drop to around $180 per metric ton by mid-2020.

However, as economies began to recover and adapt to the new normal, the demand for calcium hydroxide gradually rebounded. By the end of 2021, prices had recovered to approximately $220 per metric ton. The recovery was driven by the resumption of construction activities, increased infrastructure spending, and continued demand from the water treatment sector.

2022 to 2023

The period from 2022 to 2023 saw further stabilization and growth in the calcium hydroxide market. Supply chain disruptions eased, and industrial activities resumed at pre-pandemic levels. The construction industry’s robust performance, particularly in developing regions, and ongoing investments in water treatment infrastructure contributed to increased demand. By mid-2023, prices had risen to around $250 per metric ton.

Market Dynamics

Supply and Demand

The balance of supply and demand plays a crucial role in determining the price of calcium hydroxide. Key factors affecting supply include the availability of raw materials (limestone), production capacity, and operational efficiencies.
