For the First Half of 2022

Calcium alginate is the calcium salt of alginic acid or alginate extracted from seaweed. The price of feedstock seaweed governs the price trends for calcium alginate globally. Southeast Asia fulfils the majority of the global seaweed demand. Recently the prices of Indonesian seaweed (the largest producer) have been highly volatile, making it difficult for farmers to earn a sustainable living.

Since China is the principal processor of seaweed, feedstock prices mainly depend on robust demand from China. With zero-tolerance covid restrictions placed by the Chinese government, the manufacturing industry suffered. Even after removing restrictions, the turnaround was not optimum as the market demand sentiment suffered from inflated prices and supply-side constraints.

This fall in demand from China negatively impacted Indonesian seaweed prices, which further affected the prices of calcium alginate. Also, the export restrictions placed by the Indonesian government and depreciation against the US dollar further crashed seaweed prices. The prices of seaweed in China averaged 2.97-4.21 USD/kg, while that in Europe averaged 3.56-3.87 USD/kg.

However, in the US domestic market, the seaweed prices were slightly raised due to higher demand averaging 10.55 USD/kg. Despite the oscillating trends in seaweed prices, calcium alginate prices remained afloat in the global market owing to the steady demand from the pharmaceutical and dental industries.

Production Processes

  • Production of Calcium Alginate from Extraction Process

The seaweed is broken into pieces to extract the alginate and stirred with a hot sodium carbonate solution. It then separates as a thick slurry of sodium alginate. The slurry is then diluted with water and subjected to many filtration processes to remove the impurities. Then the sodium alginate is treated with an aqueous solution of calcium chloride; thus, the required product calcium alginate separates from the solution.


The displayed pricing data is derived through weighted average purchase price, including contract and spot transactions at the specified locations unless otherwise stated.
