Seaweed is gaining traction in the feed market, given its sustainability and nutritional profile. However, there are several risks that could undermine its long-term viability. Climate change and overharvesting threaten the availability of seaweed, causing price spikes and shortages. Standardization becomes a challenge due to inconsistent raw material quality, which can lead to inefficient feed formulations over time.
Widespread adoption is limited by elevated production and processing costs when extraction and refinement methods are still costly. To improve profitability, companies need to implement advanced, cost-effective processing technologies. There are also regulatory hurdles, as seaweed harvesting, processing, and animal feed formulations are restricted differently from place to place. Compliance with various jurisdictions may slow the market expansion.
Another risk is the lack of awareness among farmers of the benefits of seaweed-based feed. There is a hesitance to move away from commodity-based feeds due to cost and performance concerns. Adoption could be expanded further through targeted education initiatives and partnerships with agricultural bodies.
Moreover, if conventional feed ingredients and other sustainable feed sources, such as insect-based protein, are competitive in the market, they may affect the market share. Research, differentiated products, and market innovation are crucial for companies. By making the right decisions focusing on sustainable sourcing, regulatory approvals, production scale-up, and consumption of marketing with sustainability, firms can achieve long-term sustainability in the industry.
