The environmental impact of drug manufacturing raises concerns about sustainability in healthcare. To address this, exploring alternative approaches to drug production is crucial. This review focuses on seaweed as a sustainable resource for greening drug manufacturing processes. Seaweed offers advantages such as renewability, abundance, and a positive environmental footprint. The review begins by providing an overview of sustainable drug manufacturing practices and the challenges faced in achieving sustainability. It then discusses seaweed as a sustainable resource, including cultivation techniques and environmental benefits. Seaweed has various applications in drug manufacturing, including extracting and purifying bioactive compounds with potential therapeutic properties. Seaweed’s role in developing green technologies, such as seaweed-based excipients, biodegradable packaging materials, and as a source of sustainable energy for drug manufacturing processes, is highlighted. The environmental and economic implications of incorporating seaweed-based solutions are discussed, emphasizing reduced carbon footprint and cost-effectiveness. Regulatory and industrial perspectives are addressed, examining challenges, and opportunities for implementing seaweed-based drug manufacturing. Collaboration between academia, industry, and regulatory bodies is crucial for successful integration. The review presents future directions and opportunities, including emerging trends and innovations in seaweed-based drug manufacturing, areas for further research, policy development, and industry engagement recommendations. Incorporating seaweed into drug production facilitates a reduction in environmental impact, promotes resource efficiency, and contributes to sustainable healthcare. This review showcases seaweed-based solutions as a means to foster a greener future for drug manufacturing, addressing environmental concerns, and promoting sustainability.

“…Weights were recorded (to the nearest 0.01 g) using a digital scale after placing the abalone on a paper towel to remove excess water. Maximum shell lengths were measured according to established methods (Gareth et al, 2017;Hamilton et al, 2022), with calipers (to the nearest 0.1 mm). The following equation was used to calculate body weight ratio: BWR = W=SL Here, the body weight ratio (BWR) was calculated using weight (W) and shell length (SL).…”

Changes in climate conditions can have cascading repercussions for organismal performance and survival, altering the productivity of aquatic systems. While numerous studies have examined the direct effects of temperature on species fitness, fewer studies have analyzed how individual impacts may translate to downstream primary consumers. Temperature-induced changes in the nutritional quality of seaweed may cause critical shifts in energy and nutrient availability for these consumers. A multifaceted experiment was conducted to assess the indirect impacts of California’s coastal climate conditions on abalone growth. This experiment fed juvenile red abalone (Haliotis rufescens) of two different size classes in ambient water conditions with the seaweed dulse (Devaleraea mollis), conditioned at 13°C, 15°C, and 17°C for 92 days. Nutritional analyses revealed significantly higher protein and nitrogen content in the 17°C dulse culture than in the 15°C and 13°C cultures, and no significant differences in carbohydrates. Furthermore, analyses on body weight ratio and condition factor indicate that juvenile red abalone of smaller size display significantly better growth and condition when fed dulse cultured at higher temperatures. Differences between size classes suggest that temperature changes, and subsequent shifts in the nutritional composition of dulse, may have greater impacts on smaller, younger red abalone.

“…This is due to algal consumption of bivalve-produced carbon and nitrogen and increased photosynthetic abilities due to clearer waters (Cuomo et al 1997, Ajjabi et al 2017, Hargrave et al 2022). Finally, under future ocean acidification conditions, coculture may provide a physiological refuge for bivalves as demonstrated across taxa and regions (Fernández et al 2019, Tan & Zheng 2020, Hamilton et al 2022, Jiang et al 2022, Young et al 2022), potentially mitigating the severity of OA impacts on future production.…”
