Okhotsk Starfish Protects "Sky Safety." Realizing Product Commercialization with Japan's Repellent Technology to Prevent Bird Strikes at Airports, Wind Power Plants, etc.!!

Hokkaido Environmental Bio-sector Co., Ltd. (Location: Chuo-ku, Sapporo) endorses April Dream, which aims to make April 1st a day to express dreams. This press release is the dream of "Hokkaido Environmental Bio-sector."

ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー

Hokkaido Environmental Bio-sector Co., Ltd. (Chuo-ku, Sapporo, Hokkaido; Representative Director: Koji Mikuni) has been developing its unique bird repellent technology since 2002. This time, we are accelerating the full-scale product development of a high-performance repellent specifically designed to prevent bird strikes at airports and wind power plants.

Purpose and Background of the Repellent

Hokkaido Environmental Bio-sector Co., Ltd. focused on the unknown potential of "starfish," which had been considered a nuisance in its long-standing fishery waste treatment business. As a result of extensive research, we discovered that a specific component extracted from starfish, "**Marine Saponin**," has a powerful repellent effect on birds (such as crows). This discovery became the origin of product development that fundamentally changes conventional bird damage countermeasures.

Large quantities of starfish are processed using our unique biotechnology (two scenes below).

Starfish harvested in large quantities, preying on scallops.

Starfish rapidly decomposed by bio-fermentation.

The characteristic of starfish extract "Marine Saponin" is that it is "purely a natural ingredient" with no chemical components used. The extract, produced by our unique biotechnology (almost odorless), utilizes a mechanism that crows instinctively avoid (recognition of UV light emission). Instead of the conventional approach of "eliminating with poison," it creates an environment that "keeps birds away" by appealing to their physiological functions.
