The global lime kiln dust (LKD) market size is expected to witness potential gains in the future and register a significant CAGR over the forecast period (2019 - 2027).

Market Overview

LKD is obtained as a byproduct from the production of quick lime and is generally disposed into landfills. LKD can be used as an activator in pozzolanic stabilized base mixtures. It is used to remove impurities in steel manufacturing industry. The chemical structure of quicklime and inert materials makes LKD an ideal candidate for drying and modifying certain types of soils. LKD can also be used as an alternative binder to stabilize construction and demolition materials. It can be reused to reduce environmental problems and promote sustainability.

Market Dynamics

Major factor boosting growth of the global lime kiln dust market is increasing demand for LKD from the agriculture sector. In the agricultural sector, LKD is used in soil-liming process and soil conditioning. LKD can offer significant enhancement to soil properties and reduce plasticity and swelling potential and increase strength and durability. Soils treated with LKD show high strength gain. Hence, LKD is used as a soil stabilization agent in the agricultural sector.

LKD is also used for soil drying as lime decreases the soil moisture content and increases the soil’s optimum moisture content. This property of LKD increases its demand from the construction industry, especially in rainy season or places where land is wet and not suitable for construction activities. Therefore, increasing demand for LKD from the construction industry is expected to boost the market growth.   

Market Outlook

LKD is majorly produced in Asia Pacific in the economies of China and India. Therefore, increasing production of LKD in China, Japan, and India is expected to contribute to the market share of Asia Pacific. Moreover, Asia Pacific is also expected to hold dominant position in the market, followed by Europe and North America. The market in North America is majorly driven significant production of LKD in U.S.

Although LKD is not considered as a carcinogen by several regulatory bodies, the dust may contain trace amounts of crystalline silica, which is listed as a carcinogen by several regulatory bodies. This in turn may hinder growth of the market to some extent
