“…Pyrolysis is the most commonly used method for the preparation of carbons from biomass under a certain temperature and atmosphere. [56,[102][103][104][105][106][107][108][109] Fu et al [110] used different macroalgae as raw materials to obtain carbons after pyrolysis. The results showed that the pyrolysis temperature can change the carbon structure, thereby affecting the adsorption mechanism for organic pollutants.…”

“…Other redox transition elements are also applied in the preparation of bimetallic metal-carbon composites. For example, Yang et al [56] took algae enteromorpha (EP) as the carbon source, and prepared a novel multi-wrinkled biomass carbon (CoO x /MoO y @MWBC) by doping bimetallic oxides (cobalt oxide and molybdenum oxide) with a Co loading of 3.26 wt.% and Mo loading of 1.03 wt.%, which delivered a high adsorption performance for methyl blue (MB) (1587.3 mg g −1 ) with an excellent stability and reproducibility (Table 2). The adsorbents could be easily separated from water through external magnetic field without any organic reagents, followed by a simple regeneration via ethanol washing.…”

“…After cycling for at least 10 times, the removal rate kept steady at 91.6%. [56] Notably, magnetic biochar (MAC) is a series of metal-modified (e.g., Fe-and Ni-based species) porous carbon composite materials with a high adsorption capacity. [242,[245][246][247][248] On the surface of carbon adsorbents, those magnetic active materials adsorbing pollutants can be separated from liquid phases simply by magnetic field without losing the active adsorption sites, enhancing the recyclability of adsorbent materials.…”

“…[55] Despite their good adsorption properties, the disadvantages such as high cost, complex preparation and non-renewability retard their commercial application. [56] Therefore, it is of great significance to explore a kind of cost-effective, highly efficient, practical and renewable adsorbents.…”

With the development of economy and increasing environmental awareness, how to effectively remove organic pollutants in wastewater is a research hotspot. Adsorption is one of the effective methods, and the adsorption material is the key factor to determine the efficiency. In this review, biomass‐derived carbon materials as adsorbents of organic pollutants and the adsorption mechanism are discussed in depth. The effects of carbonization and activation on the morphology and structure of carbon materials; the modification strategies of carbon adsorbents, the adsorption performance of biomass‐derived carbon materials for organic pollutants are described and illustrated; the future work of the biomass‐derived carbon materials is proposed.

“…The use of macroalgae biomass for biochar (charcoal) production, with energy co-generation potential, provides a value-driven model to sequester carbon and recycle nutrients (Bird et al, 2011). In specific cases, macroalgal biomass can be used as biochar and magnetic biochar precursor, as shown in several cases using brown or green macroalgae (Jung et al, 2016;Son et al, 2018a,b;Foroutan et al, 2019;Jung et al, 2019;Yang et al, 2019). The prepared magnetic biochars were employed as efficient adsorbents of acetylsalicylic acid, water-soluble organic dyes and copper ions (Jung et al, 2019).…”

Valorization of Marine Waste: Use of Industrial By-Products and Beach Wrack Towards the Production of High Added-Value Products

et al. 2021

Biomass is defined as organic matter from living organisms represented in all kingdoms. It is recognized to be an excellent source of proteins, polysaccharides and lipids and, as such, embodies a tailored feedstock for new products and processes to apply in green industries. The industrial processes focused on the valorization of terrestrial biomass are well established, but marine sources still represent an untapped resource. Oceans and seas occupy over 70% of the Earth’s surface and are used intensively in worldwide economies through the fishery industry, as logistical routes, for mining ores and exploitation of fossil fuels, among others. All these activities produce waste. The other source of unused biomass derives from the beach wrack or washed-ashore organic material, especially in highly eutrophicated marine ecosystems. The development of high-added-value products from these side streams has been given priority in recent years due to the detection of a broad range of biopolymers, multiple nutrients and functional compounds that could find applications for human consumption or use in livestock/pet food, pharmaceutical and other industries. This review comprises a broad thematic approach in marine waste valorization, addressing the main achievements in marine biotechnology for advancing the circular economy, ranging from bioremediation applications for pollution treatment to energy and valorization for biomedical applications. It also includes a broad overview of the valorization of side streams in three selected case study areas: Norway, Scotland, and the Baltic Sea.
