Algae / spirulina cultivation vessel, built from a recycled IBC tote
A reclaimed food-grade HDPE bladder provides large, durable, chemically-resistant capacity at a fraction of a new purpose-built container, while diverting a robust vessel from the waste stream and avoiding the embodied carbon of virgin plastic.
Recycled IBC
Reuses a durable, standardised container. Diverts it from scrap and avoids new-material carbon.
a purpose-built poly tank or container
A purpose-built product — bought new, moulded or fabricated from virgin material.

A real-world write-up with photos of this reuse in practice.
A reclaimed food-grade HDPE bladder provides large, durable, chemically-resistant capacity at a fraction of a new purpose-built container, while diverting a robust vessel from the waste stream and avoiding the embodied carbon of virgin plastic. That advantage is real for this job specifically — not a blanket claim that a tote is best for everything.
Suitability & safety
Prefer a documented previous-food-use bladder. Treat any non-food or unknown-history tote conservatively and confirm prior contents before reuse.
For any water-holding reuse, shield the bladder from sunlight to prevent algae, fit food-safe fittings, and rinse thoroughly before first use.
