PT Petrokimia Gresik (Persero), an agro-industry solutions company\nand member of the PT Pupuk Indonesia (Persero) holding, has successfully\ndeveloped an innovation to utilise silica by-products as a filtering\nmaterial for liquid sulphur during the sulphuric acid production\nprocess. This innovation transforms a material that was previously a\nmanagement challenge into a useful resource, while simultaneously\nreducing the company\u2019s dependence on external filtering materials.<\/p>\n
The President Director of Petrokimia Gresik, Daconi Khotob, stated on\nMonday (21\/09\/2026) that the innovation has been granted a Simple Patent\nCertificate by the Ministry of Law of the Republic of Indonesia. The\ncertificate was presented directly by the Minister of Law, Supratman\nAndi Agtas, to the Senior Vice President (SVP) of Operations III at\nPetrokimia Gresik, Bambang Ariwibowo, during the \u201cWhat\u2019s Up Campus Calls\nOut\u201d (WCCO) event organised by the Ministry of Law at the Airlangga\nConvention Centre recently.<\/p>\n
\u201cPreviously, the filtration of liquid sulphur utilised diatomaceous\nearth sourced from third parties. Through this innovation, we have not\nonly found a solution for the silica by-products generated by the\ncompany, but we have also introduced an alternative filtering material\nthat can support production process efficiency,\u201d said Daconi.<\/p>\n
Silica is a by-product of the aluminium fluoride (AlF\u2083) production\nprocess. Every month, this production unit generates approximately 990\ntonnes of silica in solid form. This volume requires adequate management\nand storage areas.<\/p>\n
This challenge prompted Petrokimia Gresik to develop silica as an\nalternative filtering material for the sulphuric acid production\nprocess.<\/p>\n
Sulphuric acid is one of the essential materials used in fertiliser\nproduction. The production process involves a stage of filtering liquid\nsulphur to produce clean material that meets quality standards. Through\nthe innovation developed by Petrokimia Gresik, the silica resulting from\naluminium fluoride production can now be utilised as an alternative\nfiltering material in this process.<\/p>\n
The utilisation of silica provides dual benefits for the company. In\naddition to optimising by-products to ensure they have practical\nutility, the innovation also reduces the need for filtering materials\nfrom external parties and has the potential to lower production\ncosts.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/petrokimia-gresik-develops-silica-into-filtering-material-to-reduce-production-costs-1790045919", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
