Inside the L&S Sweeteners Case: CAST’s Real-World Success in Zero-Liquid Discharge

May 7, 2025

L&S Sweeteners, a major player in the sweetener production industry, faced a serious wastewater challenge:

how to process high-strength waste streams without relying on energy-intensive distillation or chemical-heavy treatments.

Their solution? CAST.

Once installed, the CAST system delivered:

  • Zero-liquid discharge — eliminating wastewater outputs entirely.

  • High-value resource recovery — reclaiming chemicals that would otherwise have been lost.

  • Dramatic waste reduction — cutting hazardous waste volumes to a fraction of their previous levels.

“CAST helped us eliminate wastewater and reclaim value — a complete game-changer.”

The result wasn’t just environmental compliance — it was operational and financial transformation.

For investors, this success story is a powerful proof point: CAST isn’t confined to lab tests or theoretical models.

It’s a proven, field-tested system that solves urgent problems and creates measurable value for its clients.
