From how we make our products to how we deliver them, HASA is committed to doing right by our customers, our communities, and the planet.

We Make Caring for the Planet a Priority

Our commitment to the environment goes beyond legal compliance. From our high-performing, concentrated sodium hypochlorite solutions to our returnable container and bulk delivery systems, we're always seeking better ways to reduce material waste and improve long-term sustainability. 

  • 25M+ plastic bottles kept out of landfills every year

  • 5M+ reusable bottles in circulation, refilled and returned

  • 100% recyclable bottles, with no single-use packaging

  • 4x1 deposit cases returned, refilled and reused

How the Closed Loop Model Works

Every HASA container is designed to come back. Here's how one bottle stays in use, delivery after delivery.

Deliver

We fill containers at a nearby HASA facility and deliver them on our own fleet to distributors, retailers, and job sites.

Use

Pool pros pick up fresh, full-strength product and put it to work.

Return

Empty containers come back to the counter or get collected on site. There's nothing to throw away.

Refill and Repeat

We pick up the empties on our regular routes, inspect and refill them, and send them back out.

Better for the Planet

How we make and deliver our products means less waste, a better product, and easier operations.

Less Waste

Returnable containers help reduce empty bottles piling up in the truck or back room, and they cut down on single-use packaging waste.

A Better Product

Liquid chlorine is sodium hypochlorite, and it breaks down to salt after it does its job. HASA’s advanced filtration helps produce a cleaner, more stable product.
