chitin nanofibrils to stabilize long life pickering foams and their application for lightweight porous materials
ACS Sustainable Chemistry & Engineering, 2018Co-Authors: Yao Huang, Jingqi Yang, Lingyun Chen, Lina ZhangAbstract:The demand of sustainable development is challenging researchers to convert renewable resourced biomass into functional materials via environmentally friendly and sustainable pathways. This work introduces a long-life Pickering foam stabilized by chitin nanofibers (CNFs) as colloidal rod-like particles, and a facile method for fabricating lightweight porous solid foams that recycles biomass materials derived from Seafood Waste. These foams were formed by combining nonionic surfactant Tween 20 (T20) and CNFs, with the CNFs being irreversibly adsorbed at the air–water interface to provide Pickering stabilization. At a concentration of 7.5 mg/mL, the foams could be stable for over 1 week without any apparent drainage. The rheological data indicated the formation of gel networks by self-aggregated CNFs at the air–water interface, which provided long-term stabilization by preventing foam coalescence and disproportionation. This long-term stability of CNF-T20 wet foam has permitted the fabrication of solid poro...

This long-term stability of CNF-T20 wet foam has permitted the fabrication of solid porous matrix by removal of the water through simple air-drying. The air-dried chitin foams were ultralight weight porous materials with porosity of 99.4% and a density of 8.84 kg/m3. In addition, they exhibited significantly improved mechanical performance (Young’s modulus of ∼290.2 kPa) compared to porous chitin materials of comparable densities prepared by a traditional freeze-drying method. Therefore, this research has provided a convenient pathway for scalable processing of macroporous material from renewable biomass for potential applications in packaging, pollutant treatment, catalysis, tissue engineering and other related fields

nitrogen rich hard carbon as a highly durable anode for high power potassium ion batteries
Energy Storage Materials, 2017Co-Authors: Chaoji Chen, Zhenggang Wang, Bao Zhang, Ling Miao, Jie Cai, Linfeng Peng, Yangyang Huang, Jianjun Jiang, Yunhui Huang, Lina ZhangAbstract:Abstract Carbonaceous electrode materials for potassium-ion batteries (KIBs) are attractive due to the abundant resource of potassium and their rational capability. However, their rate capability and cycle life are mainly hindered by the intercalation chemistry involving repeated potassium insertion/extraction that are difficult to maintain within a short time or long-term cycling. Here, for the first time, a Seafood Waste (chitin)-derived hierarchically porous nitrogen-doped carbon microsphere (NCS) electrode with a surface-driven potassium storage mechanism is developed. The NCS electrode demonstrates a record high rate capability of 154 mA h g−1 at 72 C and ultralong cycle life of 4000 cycles without obvious capacity decay (180 mA h g−1 at 1.8 C), representing the best rate capability and longest cycle life among all electrodes in KIBs and even supassing most electrodes in sodium-ion batteries (NIBs). Further kinetic analysis and first-principle calculations reveal the dominated capacitive surface-driven mechanism of potassium storage in NCS, which is attributed to the hierarchically porous microstructure and nitrogen-doped carbon structure with enhanced potassium adsorption capability and electronic/ionic conductivities.

unique elastic n doped carbon nanofibrous microspheres with hierarchical porosity derived from renewable chitin for high rate supercapacitors
Nano Energy, 2016Co-Authors: Bo Duan, Yan Fang, Liang Huang, Jun Zhou, Lina ZhangAbstract:Abstract Chitin derived from discarded Seafood Waste (crab and shrimp shell) is a naturally abundant resource, but its difficult dissolubility limits the processing and applications. Herein, we prepared nanofibrous microspheres by using chitin solution dissolved in NaOH/urea aqueous solvent at low temperature, and subsequently fabricated the novel elastic nitrogen-doped carbon microspheres by pyrolyzing the chitin microspheres. Interestingly, the carbon microspheres were consisted of robust cross-linked nanofibers and displayed interconnected nanofibrous framework architecture, named as CNFF. The CNFF microspheres showed unique elasticity, excellent compression behaviors, and the morphology recovered completely over 5 cyclic compression at strain 75%. Moreover, the carbon microspheres exhibited an outstanding rate capability with a capacitance retention of ~50% when increase the scan rate from 5 mV/s to 10,000 mV/s as well as good cycling stability for supercapacitor applications, as a result of their hierarchical porosity, stable 3D interconnected mesh structure and ultrahigh specific surface area (over 1000 m2/g). Particularly, in the organic electrolyte, the highest deliverable energy density reached up to 58.7 Wh/kg. This work opened up a completely new and green avenue for constructing high performance carbon-based material with elasticity from biomass Waste, showing promising application in the energy storage field.

from Seafood Waste to active Seafood packaging an emerging opportunity of the circular economy
Journal of Cleaner Production, 2019Co-Authors: Koro De La Caba, Pedro Guerrero, Trang Si Trung, Malco C Cruzromero, J P Kerry, Joachim W Fluhr, Marcus Maurer, Froukje Kruijssen, Amaya Albalat, Stuart W BuntingAbstract:Abstract Sustainable development is an overarching objective that requires an interdisciplinary approach in order to address the societal challenge concerning climate action, environment, resource efficiency and raw materials. In this context, valorization of abundant and available bio-Wastes with high potential to manufacture value-added products is the first step to close the loop between Waste and consumption in line with the main goal of the circular economy. In the last years, many research works have been published in the literature regarding novel food packaging. However, most of them are focused on packaging composition (scientific aspects) and some of them on the packaging manufacture (technological aspects), but very few studies are concerned about the influence of bringing novel food packaging systems into the market on environmental, social and economic issues. In this regard, this review intends to fill this gap, considering the potential of developing food packaging from food processing Waste in order to create business for food industries, being aware of the food quality demanded by consumers and the environmental care demanded by institutions and society.

an analysis of food Waste from a flight catering business for sustainable food Waste management a case study of halal food production process
Journal of Cleaner Production, 2019Co-Authors: Metawe Thamagasorn, Chanathip PharinoAbstract:Abstract The airline business is a capital-intensive industry that consumes a large amount of resources in order to provide its services. The provision of food for airline passengers demonstrates an unsustainable consumption and production pattern and food Waste from flight catering poses a significant sustainability issue, not only because valuable caloric content is lost, but also the loss of land, water and energy required in the production of food. A conduct of literature review of food Waste management in airline catering business revealed a lack of research in this area. Through a case study of Halal food production process, the research aims to identify the amount of food Waste generated from Halal kitchen flight catering production process in order to identify food Waste hotspots by conducting a food Waste composition analysis, Material Flow Analysis and eco-efficiency analysis. It also endeavors to provide insights that can help organizations better understand the food Waste generation and composition imperative to the establishment of food Waste management policies and make informed decisions to ensure that the future growth is more sustainable. One of the goals of this research is to develop a recommendation for sustainable food Waste management by promoting the most preferred approaches of sustainable food Waste management, which can prevent and reduce food wastage at source instead of the least preferred approach, which is recovering energy before landfill disposal. This research found that vegetable Wastes accounted for 40–50 percent of the total food generated in the operation. From the quantitative analyses, it is recommended that the company prioritize its efforts in reducing Seafood Waste due to relatively high impact the reduction in Seafood Wastes will have in terms of cost-savings potential. This can be achieved by designing menus and recipes that aim to utilize Seafood efficiently in combination with starting a dialogue with airline customers on the benefits of food Waste reduction. The material flow diagram clearly illustrates the hotspots in the halal production process. Although the meal portioning process did not generate the highest amount of food Waste, but in terms of edibility, this process generated the highest amount of Wasted food (edible parts). Measures should be established in order to address the inefficiencies in the resource use. The company can reduce vegetables Waste by selecting high quality suppliers, improve the effectiveness of selection and quality control process by providing additional training, changing the washing process and investing in new technology that facilitate staff in their jobs.
