What Jundu does

Mineração Jundu Ltda is a Brazilian producer of non-metallic industrial minerals, founded in 1956 and headquartered in Descalvado, São Paulo. The company operates seven production units across São Paulo, Santa Catarina, Sergipe, Bahia, and Minas Gerais, and is jointly owned by Saint-Gobain and Sibelco, two of the world's largest industrial minerals groups. Core product offerings span high-purity quartz sand, resinated sands, ground silica, limestone, and dolomite, serving customers in glass manufacturing, fiberglass, construction, foundry, ceramics, oil & gas, and filtration. The company pioneered Shell Molding (resinated sand) technology in Brazil in 1972 and was the first in the country's non-metallic minerals segment to obtain Environmental Product Declaration (EPD) certification across all product lines (2024).

Jundu extends its industrial mineral base through a portfolio of specialized sub-brands including SuperQuadra (sand sports ecosystem with mobile app and 1,000 courts sold across 8 Brazilian states since 2019), Grand Pista (equestrian arena sand), Manamá (Inmetro-certified children's play sand, sold via retail and e-commerce), Printsil (Brazil's first 3D printing sand for foundry), Oásis, Lumière, Thermoflow (fluidized bed boiler sand), and Golf. The company holds ISO 9001 and ISO 14001 certifications, operates a Pilot Plant at Descalvado for R&D, and was recognized with supplier-of-the-year awards from Dexco, Castelatto, and innovation recognition from Owens Corning and Verallia.

Revenue is generated through direct enterprise B2B sales to industrial manufacturers (glass, foundry, construction, fiberglass) supplemented by consumer product sales for Manamá play sand and direct-to-facility sales for sports sand brands. Pricing is quote-based and not publicly disclosed. Distribution combines dedicated regional sales coordinators for industrial accounts, retail partners and e-commerce (Mercado Livre) for consumer products, and proprietary mobile applications for the SuperQuadra sports ecosystem. GTM relies heavily on industry trade show participation (FEICON, FENAF, CBC Clubes & Expo, SUSFYS) and recognized enterprise customer awards as third-party validation.
