In terms of revenue, the global specialty sorbents market was valued at $762 million in 2016. It is expected to be valued at more than $1.2 billion in 2022, increasing at a compound annual growth rate (CAGR) of 8.3% during the forecast period of 2017 through 2022. This report segments the overall specialty sorbents market into materials, applications and regions.
Sorbents are materials used to absorb or adsorb liquids or gases. In some industrial applications, sorbent materials are used to recover the fluids used during the manufacturing or reaction process. Upgraded and modified materials used for specific end uses for absorption or adsorption applications are known as specialty sorbents. Sorbents have wide application in industries such as oil and gas, food and beverages, pharmaceuticals and others. Some of the major specialty sorbents materials in terms of
materials are carbon black, chitosan and engineered nanomaterials.
Carbon black is produced by incomplete combustion of petroleum products such as coal tar, vegetable oil and FCC tar. Carbon black has a high surface-area-to-volume ratio. However, it has lower surfacearea- to-volume ratio than that of activated carbon. Chitosan is a synthetic flocculant. Chitosan molecules contain an amino group that imparts its absorption property. The amino group acts a good sorbent for cationic ions. Hence, chitosan is extensively used as a sorbent for heavy metal ions. Chitosan sorbents can be used for water treatment, sludge treatment and processing of industrial wastes.
Engineered nanomaterials have recently been manufactured in different forms and shapes. These nanomaterials are integrated into composites. They are also functionalized by a set of functionalizing compounds and active components. Some of the most commonly used engineered nanomaterials are carbon nanotubes, titania, dendrimers, silver nanomaterials and zero-valent iron.
In 2016, chitosan accounted for the greatest share of demand for specialty sorbents in terms of materials. Chitosan accounted for REDACTED of demand in 2016 and is projected to expand at a CAGR of REDACTED from 2017 through 2022. Engineered nanomaterials are projected to be the fastest growingsegment during the forecast period. The developments and extensive research in the field of nanotechnology are boosting the growth in the demand for engineered nanomaterials specialty sorbents. Engineered nanomaterials accounted for a REDACTED share of demand in 2016, which is projectedto increase to REDACTED by 2022, growing at a CAGR of REDACTED from 2017 through 2022.
Increased investments in municipal and industrial infrastructure in the emerging markets and the expansion of the global construction industry are the two major drivers of the global specialty sorbents market. Global construction output is expected to reach more than REDACTED by 2030 from REDACTED in 2015 at an average growth rate of REDACTED per year, driven primarily by the emerging markets, such asChina, India, the Gulf Cooperation Council (GCC), Indonesia and other developing regions. Even thoughthe global financial crisis affected the industry, investment in the emerging markets has been increasingat a significant rate compared with that of Western regions.
The introduction of absorbent materials into the construction industry as a new component to produce concrete materials has created several new opportunities in terms of water control in concrete. The control of water in concrete has several benefits such as an influence on strength, shrinkage reduction during hardening, frost protection and rheology modification. The application of specialty sorbents in modern concrete technology has also reduced the challenge of creating advantageous pore systems in concrete to increase its durability, mainly in terms of freeze-thaw resistance. This has created strong demand for specialty sorbents as a robust solution to remaining stable regardless of the consistency of the concrete. Sorbents also act as a micro-reservoir for chemical substances that are released under certain conditions such as changes in the chemical composition of pore solutions, temperature and duration.
