"Glassblast" or surface cleaner
The majority of container glass is recycled back into new containers to package food and beverages. However, many companies and counties are exploring alternative recycling options for post-consumer glass.
Glass beads are used in blasting and surface-cleaning applications. Blasting with glass beads made of recycled glass can perform better in certain applications than virgin glass beads. The abrasion of the crushed glass can improve the quality of the blast. Beads sold in Minnesota range from 95-100% recycled post-consumer content.
OSHA-approved. The federal Occupational Health and Safety Administration (OSHA) has classified the dust created from glass blasting as a "nuisance dust." Glass does not contribute to the lung disease silicosis. However, dust resulting from surface cleaning with sand (crystalline silica) is considered a contributor to the lung disease silicosis.
