The Company has the Limestone Products from the lime quarry production distributed by Thai Marble Corporation Limited (Subsidiary Company) and the product type as follows:

• High-Calcium Limestone The main material used for Calcium Oxide and Calcium Hydroxide production or generally called lime products. Limestone, a sedimentary rock that consists mostly of calcium carbonate (CaCO3) consisting of more than 95% of CaCO3 including other compositions such as MgO and SiO2. The produced KFS will be in a small size 30-65 mm. (“KFS Small”) and in bigger size 65-115 mm. (KFS Large”). The production capacity of KFS depends on the demand for lime production which is not less than 80% of the demand for lime production of Golden Lime PLC – the monopoly buyer with TMC according to the KFS purchase agreement signed by both parties and the purchase price based on the Arm’s Length Basic.
• Ready-Mixed Stone By-products from the lime production in small sizes between 15-25 mm. used for ready-mixed concrete production for construction.
• ROM Aggregate By-products from the High-Calcium Limestone sorting. ROM Aggregate is the limestone with impurities in mixed-sizes between 0-1,000 mm. that are unsuitable for lime production but can be used to produce stone for construction mostly to crush and mix with concrete, road construction and general construction.
• Stone ChipsThe crushed limestone is a by-product from the mill plant or the limestone crushing process in mixed-sizes between 0-25 mm. It is unsuitable for lime production due to containing impurities and has a minimal size. This kind of stone is mostly used as the road foundation, road compaction base, road levelling, landfilling, or brick block production. The stone chips divide into various grades depends on the suitability of use. When it is compacted can make the surface to be stronger and more solid than laterite soil.
• Stone Dust The coarse crushed stone, a by-product from the mill plant or from the limestone crushing process with a size of dust to coarse between 0 - 3 mm. used for the general construction, paving bricks, pavement bricks, interlocking bricks, multipurpose bricks, to make pavement for sports fields, garden decoration, sidewalks, slurry seal, asphalt concrete mixture and for agriculture, it can be used to adjust the pH of the soil.
