Import Broken Glass Cullet — Buy in wholesale FOB from Supplier in China

Shanghai Winslow Industrial Equipment Co., Ltd. offers recycled glass cullet crushed from post-consumer containers for use in new glass manufacturing, fiberglass insulation, and secondary industrial applications. The material is colour-sorted, cleaned, and crushed prior to sale, though specific purity percentages, crush size fractions, and moisture data are not provided in the listing. The supplier is based in Shanghai's Hongkou District, operating from a commercial address rather than a production facility.

Glass cullet chemistry depends on the original container mix, typically soda-lime-silica compositions with 70-74% SiO2, 12-15% Na2O, and 10-13% CaO by weight. The infinite recyclability of glass means no degradation in chemical structure with repeated remelting, provided organics, ceramics, and metals are excluded. Standard industry practice requires removal of bottle caps, labels, and closures before crushing, followed by ferrous and non-ferrous metal separation, then optical or density-based colour sorting. Buyers should ask Winslow which of these steps are performed in-house or subcontracted.

End-use applications span container glass furnaces, continuous filament fiberglass bushing operations, and abrasive blasting media. Lower-grade fractions may suit aggregate, terrazzo, or landfill drainage layers. Energy savings from cullet use are well documented: each 10% cullet addition reduces melting energy by approximately 2.5% due to lower reaction temperatures. Prospective buyers should confirm Winslow's typical delivery size distribution, available monthly tonnage, and whether technical support for furnace feed optimisation is provided.

Shanghai Winslow Industrial Equipment Co., Ltd. is registered at Room 313, Block B, 3rd Floor, Platinum Bay Plaza, No. 99 Gongping Road, Hongkou District, Shanghai, 200000, China. The commercial address in a Shanghai plaza indicates a trading, distribution, or equipment supply operation rather than a heavy industrial processing site. The harbour trust tier and 0.00% response rate signal limited platform engagement, so buyers should initiate contact through multiple channels and allow extended response times.

No manufacturing history, processing capacity, workforce scale, or annual turnover is disclosed. The company name includes 'Industrial Equipment,' which may imply machinery trading alongside material supply, or may simply reflect registration scope. Buyers should clarify whether Winslow operates crushing and cleaning equipment directly, or sources cullet from partnered recyclers. Direct factory audits or third-party verification of processing capability are advisable before committing to volume contracts.
