01Why AlgaTrop

Three things other seaweed processors can't offer you.

<2 hoursharvest to processing

Fresh seaweed, not dried and traded.

Our facility in Zamboanga City sits close to the farms. This allows us to work with only the freshest material.

Kappaphycusnot Ascophyllum

A seaweed your competitors aren't selling.

Most seaweed biostimulants start from cold-water wild-harvest sources. Ours is from a tropical red seaweed, farmed year-round at massive scale.

Philippine prices

Made here, not imported.

Philippine partners buy from a Philippine manufacturer, in pesos, without costly imports. Overseas partners get an affordable, tropical supply option outside the usual sources.
