Demand for Calcium Nitrate to Rise due to Extensive Use in Wastewater Treatment

The biogenic production of sulfide as a result of bacterial activity in wastewater treatment plants causes odors, corrosion, and toxicity problems. To prevent these problems, the use of calcium nitrate is considered effective as it sharply reduces the production of sulfide not only in water, but also in the air. Thus, there is an increasing demand for calcium nitrate from wastewater treatment plants. According to a report published by Transparency Market Research, the global calcium nitrate market will rise from US$7.37 bn in 2013 to US$10.18 bn by 2020, expanding at a CAGR of 4.8% from 2014 to 2020.

TMR analysts answer key questions that companies operating in the calcium nitrate market might have:

Q. Which region is expected to lead in the global calcium nitrate market?

The global calcium nitrate market was led by Asia Pacific in terms of region in 2013. Asia Pacific accounted for 55% of the global calcium nitrate market in 2013 and is also expected to be the fastest growing regional segment in the coming years. The growth of the market in Asia Pacific is due to the rising demand for food crops from countries such as India and China, thus increasing the demand for calcium nitrate-based fertilizers. The Rest of the World is expected to follow Asia Pacific and be the second-fastest geographical segment. The calcium nitrate market is expected to boom in the Rest of the World owing to the growth of the mining and agricultural sectors, thus boosting the demand for emulsion explosives and calcium nitrate-based fertilizers. Europe and North America will also witness moderate growth in the coming years.


Q. What is the major challenge faced by the global calcium nitrate market?

The hygroscopic nature of calcium nitrate is one of the major factors restricting the global market. Calcium nitrate is classified as hazard class 5.1 by regulatory regimes. Calcium nitrate can be quickly absorbed into the body by inhalation and ingestion. It is a strong oxidant and reacts with combustible and reducing materials. Calcium nitrate is also known to cause mechanical irritation of the eyes and respiratory tract. These factors are expected to restrain the growth of the market.

Q. What are the recent developments by key players in the market?

Yara, a European-based company, has developed Nutriox, a product that can solve odor problems or problems caused by H2S. The product prevents the exposure to the toxic gas among the employees working in wastewater treatment plants. Nutriox has no negative impact on the wastewater treatment process and prevents septicity in pipes, sewer networks, and in wastewater treatment plants.

Evoqua Water Technologies, a U.S.-based company, has launched BIOXIDE® Calcium Nitrate Solution. This solution naturally eliminates odor, corrosion, and safety issues associated with hydrogen sulfide. It achieves this by preventing the formation of hydrogen sulphide. It is one of the rare treatment methods that is not listed in the EPA CERCLA list of hazardous substances.

Such developments by market players are expected to boost the adoption of calcium nitrate and lead to significant growth in the market.
