Highchem to Showcase Innovative Solutions for Aquaculture

Highchem Inc., a Tokyo-based global chemical trading company and manufacturer, is set to make its debut at the Aquaculture Expo 2025, scheduled from October 15 to 17 at Tokyo Big Sight. The company's focus will be on presenting its advanced photo-bioreactor technology, aimed at reinforcing sustainable practices in aquaculture by efficiently cultivating microalgae.

A New Era of Fishing: The Rise of Land-Based Aquaculture

The state of Japan's fishing industry is deteriorating due to rising ocean temperatures caused by climate change, as well as overfishing leading to dwindling catches. In this context, land-based aquaculture is rapidly gaining attention as a new form of fishing that reduces environmental burden while offering a controlled environment less affected by weather. This method not only minimizes the risks associated with parasites but also provides better control over the nutritional value of farmed fish, making it a highly valuable option for aquaculture. Estimates from market research firms predict that the market for land-based aquaculture could triple by 2030.

Despite its advantages, land-based aquaculture does face challenges, particularly regarding the initial investment costs and high operational expenses related to electricity and water treatment. Highchem is committed to addressing these challenges through their photo-bioreactor technology, which offers a promising solution for land-based aquaculture operations.

Key Benefits of the Photo-Bioreactor for Aquaculture

1. High-Quality Microalgae Cultivation

The photo-bioreactor system allows for the efficient cultivation of microalgae using light and CO2. With a sealed construction made of glass or special resin, it prevents contamination and maintains the optimal growth environment for microalgae. This high-nutritional microalgae is increasingly recognized as a sustainable alternative to traditional fish feed components, such as fishmeal and fish oil. For instance, integrating microalgae into salmon feed has shown to enhance growth, maintain quality, and improve nutritional content.

2. Wastewater Management Solutions

During the aquaculture process, waste products are generated, containing nitrogen, phosphorus, ammonia, and more. Traditional methods of treating this wastewater can be costly. Highchem's photo-bioreactor system allows the integration of these waste streams into a closed-loop system, repurposing them as nutrients for microalgae, thereby creating a more sustainable aquaculture environment.

3. Effective Utilization of CO2

Moreover, this technology utilizes CO2 as a vital nutrient source for the growth of microalgae. By connecting to exhaust treatment systems in factories or boilers, this setup enhances carbon recycling, creating opportunities for carbon credits and contributing positively to environmental, social, and governance (ESG) goals.
