represents the wet weight biomass of different algae (t/year),

represents the conversion coefficients between wet weight and dry weight for different algae, and

represents the carbon content ratio of the dry mass of shells of different algae. The assessment parameters of algae carbon sink capacity [ 13 , 28 , 29 , 30 ] are shown in Table 2 .…”

Shellfish and algae mariculture make up an important part of the marine fishery carbon sink. Carbon sink research is necessary to ensure China achieves its goal of carbon neutrality. This study used the material quality assessment method to estimate the carbon sink capacity of shellfish and algae. Product value, carbon storage value, and oxygen release value were used to calculate the economic value of shellfish and algae carbon sequestration. The results showed that the annual average shellfish and algae carbon sink in China was 1.10 million tons from 2003 to 2019, of which shellfish accounted for 91.63%, wherein Crassostreagigas, Ruditapesphilippinarum, and Chlamysfarreri were the main contributors. The annual average economic value of China’s shellfish and algae carbon sequestration was USD 71,303.56 million, and the product value was the main contributor, accounting for 99.11%. The carbon sink conversion ratios of shellfish and algae were 8.37% and 5.20%, respectively, thus making shellfish the aquaculture species with the strongest carbon sink capacity and the greatest carbon sink potential. The estimated growth rate in the shellfish and algae removable carbon sink was 33,900 tons/year in China, but this trend was uncertain. The capacity for carbon sequestration and exchange by aquaculture can be improved by expanding breeding space, promoting multi-level comprehensive breeding modes, and marine artificial upwelling projects.

“…Based on the lubricating properties of original kelp, it is very meaningful to study the lubricating properties of bio-based lubricant kelp liquid (KL). The cultivation of kelp is becoming more sophisticated and some countries are planning to cultivate it in commercial activities and research areas, which will increase the production of kelp significantly in the future (Ge et al , 2015; Bak et al , 2020). As a green vegetable and with natural lubricating properties, the application of kelp to water-based lubrication provides a simpler and faster way to obtain lubricants.…”

Purpose Kelp is widely productive and inexpensive. The purpose of this study is to explore kelp liquid (KL) as an environment-friendly water-based lubricant, which is expected to replace some industrial lubricants and protect the environment while satisfying lubricating performance. Design/methodology/approach In this experiment, the soaked kelp was broken up by a wall-breaking machine to get the KL by a centrifuge. Elements and crystal structure of KL samples were characterized by X-ray photoelectron spectroscopy, X-ray diffraction and Raman spectra. The friction test is carried out by the relative movement of the polyethylene ball and the aluminum disk on the friction tester. Findings Friction experiments showed that 0.1 Wt.% KL has a good lubrication effect, and the average coefficient of friction is 0.063 under the condition of applying a 10 N load and moving at a speed of 2.0 cm/s. KL has good thermal conductivity with excellent cooling effect and high intermolecular force which makes high viscosity for excellent lubricating behavior, at the meantime molecules in solution remain stable which shows an excellent dispersibility. Originality/value At present, the research on kelp mainly focuses on its medicinal value and abundant nutritional value, and the research on its lubrication effect is less. Based on this situation, this paper explored the characteristics of KL as an environmentally friendly lubricant, which is expected to be used as a green cutting fluid.
