“…The authors reported that seaweed possessed all the necessary characteristics for classification as a blue carbon reservoir with a substantial carbon sink potential, in addition the role of seaweed in climate change mitigation, bio-economy enhancement via fossil fuel substitution, human food, biofuels, renewable biomass, and animal feed. About 50% of the world's carbon could be sequestered by seaweed (Chung et al 2011 ; Jagtap and Meena 2022 ). In addition, seaweed can offset half of the world's bioenergy, making seaweed a potential means of reducing greenhouse gas emissions (Duarte et al 2017b ).…”

“…Jagtap and Meena ( 2022 ) reported the carbon sequestration potential of certain seaweeds as follows: Eucheuma spp. can sequester 68.43 tonnes carbon/hectare/year, Kappaphycus striatum can sequester 125.51 tonnes carbon/hectare/year, Laminaria spp.…”

“…The authors projected that the seaweed industry would eliminate 100% of the total phosphorus feed into Chinese coastline waters by 2026. The World Bank estimates that a global seaweed harvest of 500 million tonnes by 2050 will be achieved, which will utilise approximately 10 million tonnes of water nitrogen, which represents 30% of the nitrogen that reaches the seas, and 15 million tonnes of phosphorus, which is about 33% of the phosphorus generated from dung and fertilisers (Jagtap and Meena 2022 ). Duan et al ( 2019 ) showed that Gracilaria lemaneiformis cultivation could sequester 1192.03 tonnes of carbon, 15.89 tonnes of phosphorus, and 128.10 tonnes of nitrogen from the Yantian Bay seawater.…”

The development and recycling of biomass production can partly solve issues of energy, climate change, population growth, food and feed shortages, and environmental pollution. For instance, the use of seaweeds as feedstocks can reduce our reliance on fossil fuel resources, ensure the synthesis of cost-effective and eco-friendly products and biofuels, and develop sustainable biorefinery processes. Nonetheless, seaweeds use in several biorefineries is still in the infancy stage compared to terrestrial plants-based lignocellulosic biomass. Therefore, here we review seaweed biorefineries with focus on seaweed production, economical benefits, and seaweed use as feedstock for anaerobic digestion, biochar, bioplastics, crop health, food, livestock feed, pharmaceuticals and cosmetics. Globally, seaweeds could sequester between 61 and 268 megatonnes of carbon per year, with an average of 173 megatonnes. Nearly 90% of carbon is sequestered by exporting biomass to deep water, while the remaining 10% is buried in coastal sediments. 500 gigatonnes of seaweeds could replace nearly 40% of the current soy protein production. Seaweeds contain valuable bioactive molecules that could be applied as antimicrobial, antioxidant, antiviral, antifungal, anticancer, contraceptive, anti-inflammatory, anti-coagulants, and in other cosmetics and skincare products.

“…Seaweed farming is increasing worldwide as part of the development of a sustainable economy [ 110 ]. China and Indonesia, where harvesting or collecting algae from the natural environment is an ancient practice, are the major seaweed-producing countries, contributing 86.6% of global seaweed production [ 60 , 111 ].…”

“…Within sustainable farming systems, seaweed cultivation is of interest because of the ecosystem services that algae provide [ 110 ]. Macroalgae possess bioremediation properties, as they are capable of minimising eutrophication by removing excess dissolved nutrients such as C, N and P [ 126 , 127 ].…”

The rabbit meat industry has faced critical challenges in the last few years, during which the ban on the prophylactic use of antibiotics in animal feed has added to the weakness of the production system and a decrease in consumption of rabbit meat. This review paper highlights the potential value of macroalgae in the rabbit farming sector as an alternative to the use of antibiotics to improve rabbit health. In line with sustainable agriculture programmes, the use of seaweed in rabbit nutrition may improve gut health according to the One Health approach, whereby consumers and the environment could receive tangible benefits. The inclusion of algae in animal feed has experimentally proven to help to reduce intestinal dysbiosis. However, further studies evaluating the prebiotic effects of algal components on gut health and also identifying the compounds directly responsible for the antimicrobial, antiviral, antioxidative and anti-inflammatory properties of algae are still needed. Furthermore, the inclusion of marine algae in rabbit food could potentially become a commercial marketing strategy that could attract new consumers who are concerned about environmental sustainability and who are looking for different, high-quality foods.
