“…Moreover, with the development of Industry 5.0 human centric technologies (Xu et al, 2021), collaborative robots (cobots) will play vital roles in agriculture, paludiculture and food production along the full value chain. These cobots will work closely with human operators to perform dangerous and less popular menial tasks along with more laborintensive, monotonous and repetitive jobs (Wong et al, 2022). Cobots can also be used as transportation for in-field logis0ics applications (Ducket et al, 2018).…”

“…After filtration of the suspension, the carrageenan is recovered from the solution by alcohol precipitation 2 . Taking into account that the content of carrageenan in red macroalgae ranges between 25% and 35% on a dry weight basis, depending on the geological distribution and harvesting season of the macroalgae, the remaining 65% of solid waste generated in its industrial extraction is a macroalgal cellulosic residue that needs to be valorised 8 …”

The industrial waste generated in the extraction of carrageenan from red seaweed, Eucheuma spinosum, was tested in this study to produce fermentable sugars that could be used for the production of high‐value‐bioproducts with a biorefinery approach. A sequential process was used: thermochemical pretreatment with HCl and enzymatic hydrolysis. Hydrogen chloride concentrations in the range from 0 mol L−1 to 0.5 mol L−1 and pretreatment times from 15 to 100 min were assayed. The best conditions found for pretreatment were HCl 0.3 mol L−1 for 60 min, leading to reducing sugar concentrations of 21.4 g L−1 (274 mg of reducing sugars per gram of algal residue). The hydrolysates coming from the sequential process under the pretreatment conditions of HCl 0.3 mol L−1 for 60 and 80 min have been used successfully for the production of polyhydroxyalkanoates by Cupriavidus necator. The yields of polyhydroxybutyrate were 0.21–0.26 g PHB g−1 reducing sugar consumed and the accumulation of the biopolymer was of the order of 58% dry cell weight.

The growing potential of sustainable materials such as polyhydroxyalkanoates (PHAs), polylactic acid (PLA), alginate, carrageenan, and ulvan for bioplastics production presents an opportunity to promote a sustainable circular economy. This review investigates their properties, applications, and challenges. Bioplastics derived from algae offer an environmentally friendly alternative to petroleum‐based plastics, a shift of paramount importance to society due to the escalating environmental concerns associated with traditional plastics. The role of the internet‐of‐things (IoT) and machine learning in refining these bioplastics' production and development processes is emphasized. IoT monitors cultivation conditions, data collection, and process control for more sustainable production. Machine learning can enhance algae cultivation, increasing the supply of raw materials for algal bioplastics and improving their efficiency and output. The study results indicate the promise of algae‐based bioplastics, IoT, and machine learning in fostering a more environmentally sustainable future. By harnessing these advanced technologies, optimization of bioplastic production is possible, potentially revolutionizing the materials industry and addressing existing challenges toward achieving a sustainable circular economy.
