With global sugar production generating roughly 30 million tonnes of ash annually, mills and packaging converters are now qualifying SCBA as a functional mineral filler, replacing purchased calcium carbonate and kaolin in molded fiber and paperboard systems. For B2B buyers, it is one of the few fillers that simultaneously lowers cost and improves circularity scoring.

Its composition varies by combustion conditions, but well-controlled ash is dominated by amorphous silica with minor alumina, iron oxide, and calcium oxide. The critical quality gate is loss on ignition (LOI): unburned carbon above 6% darkens the stock and interferes with sizing chemistry and printability.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Key Specifications for Packaging Qualification<\/h2>\n<ul style=\"margin:16px 0; padding-left:24px; line-height:1.75; color:#334155;\">\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>SiO\u2082 content:<\/strong> 60\u201375% target for pozzolanic\/filler grade; below 50% indicates soil contamination.<\/li>\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>Fineness:<\/strong> D90 \u2264 45 \u00b5m for paperboard filling; micropulverized grades (\u226410 \u00b5m) enable higher loadings.<\/li>\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>LOI:<\/strong> \u22646% for bleached\/food-adjacent grades; \u226410% acceptable for molded industrial trays.<\/li>\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>pH:<\/strong> 8\u201310 aqueous extract; verify compatibility with cationic starch and AKD sizing programs.<\/li>\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>Moisture:<\/strong> \u22643% for pneumatic dosing stability.<\/li>\n<\/ul>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Performance in Molded Fiber &#038; Paperboard<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Substituting 5\u201315% SCBA (parts per hundred fiber) in a corrugated medium or molded pulp furnish delivers measurable outcomes:<\/p>\n<ul style=\"margin:16px 0; padding-left:24px; line-height:1.75; color:#334155;\">\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>Retention:<\/strong> Silica particles retain at 70\u201385% with 0.3\u20130.5% cationic starch or retention aid, outperforming unmodified GCC in fine-fiber webs.<\/li>\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>Strength trade-off:<\/strong> Expect a 4\u20138% burst index reduction per 10% loading\u2014manageable within a 32 ECT board spec if the base furnish carries margin.<\/li>\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>Bulk and stiffness:<\/strong> Filling raises sheet stiffness-to-weight, allowing 5\u20138 g\/m\u00b2 basis weight reduction on some box grades.<\/li>\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>Drainage:<\/strong> Faster drainage on the former cuts steam demand 3\u20136% on the drying can.<\/li>\n<\/ul>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Structural teams compensating for filler dilution should review our <a href=\"https:\/\/tadapack.com\/news\/post-consumer-recycled-materials-packaging-guide\/\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"color:#0284c7; text-decoration:underline; font-weight:600;\">Post Consumer Recycled Materials: B2B Packaging Specs &#038; Performance<\/a> guide for baseline furnish data, and our <a href=\"https:\/\/tadapack.com\/news\/technology-for-post-consumer-recycled-packaging\/\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"color:#0284c7; text-decoration:underline; font-weight:600;\">Technology for Post-Consumer Recycled Packaging<\/a> article for hybrid PCR + agricultural-residue strategies.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Cost &#038; Supply Benchmarks<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Pulverized SCBA from mills with in-line grinding runs $40\u201390\/tonne delivered regionally\u2014well under GCC ($180\u2013260\/tonne).
