The technologies secured by the head office are technologies that refine and make high purity products by refining the biodiesel by-product Crude Glycerin, producing heavy oil (heavy biodiesel) with separate FFA (unused fatty acids), advanced bio-diesel technology that makes it into biodiesel for vehicles, carbon dioxide and polysilicon regeneration technology,  and advanced refining of glycol-based cut oil products.

Since 2010, we have developed and developed our own technology to regenerate slurry (submaterials) generated in the manufacturing process of solar panels and semiconductors. In 2013, we succeeded in developing renewable hydrocarbons and grinding agents used in the manufacturing process of cement. In December of the same year, we established PNC, Inc. to start manufacturing and selling solar and semiconductor regeneration in earnest.

Since its establishment as STACO Chemical in 1994, PN started by producing, importing and selling mostly industrial maintenance and repair products such as lubricants, maintenance agents, cleaning agents, and cleaning agents. However, we have secured high value-added petrochemical products such as glycerin using biodiesel production and production by-products since the early 2000s for the second leap forward. Accordingly, we have been engaged in various refining and regeneration projects related to biodiesel by products since 2007.

Our solar slurry business is a company that separates and refines the liquid and solid phase of sludge generated by wire-saw equipment used in the cutting process (mainly the multi-type wafer production process) to make silicon wafers from silicon ingots.

Liquid (Coolant) mainly uses ethylene glycol such as propylene glycol (PG), PEG, PEG+DEG mixture, DEG, etc. 
and consists of substances such as high-phase SIC, SI, FE, etc. At our company, liquid phase is reproduced and sold through filtering and distillation, and high quality is reproduced and sold through filtering, high-value separator, drying, and separation process.

Based on the excellent technology formed in this business, we manufacture, distribute, and sell various cosmetics materials, which secure excellent competitiveness in price and quality compared to other companies.
The company has secured technology to manufacture ethylene carbonate (EC) and propylene carbonate (PC), the main ingredients of secondary battery electrolyte, which are not localized at present. This is based on the technology that has been compositing EO and PO gases for many years.
