Novel biopolymer-based sustainable composites for food packaging applications: A narrative review
No full textIn the contemporary era of nutrition science, food industries are facing myriad challenges in assuring quality food with extended shelf life and long-term preservation. Biopolymer-based sustainable and biodegradable food packaging materials have helped the industries to meet these challenges. Additionally, these eco-friendly materials are also alleviating the environmental concerns associated with plastic-related pollution due to their excellent biodegradability, renewability, bioavailability, and non-toxicity. Herein, biopolymer-based food packaging materials and their composites, their biodegradation mechanisms, and the effect of nano-additives on the food packaging properties are presented. This review also elucidates ongoing research investigations for meeting current challenges by using these environmentally benign materials in food packaging applications. It is anticipated that the implementation of green technology could help in improving food quality and safety while reducing food loss and plastic waste, which will assist in achieving environmental sustainability goals.</p
Impact of bolt positioning on the stiffness of angular support brackets
Full text linkBolts and screws are usually preferred over other joining techniques when assembly and disassembly operations are required. However, they add extra weight to the system, so it is essential to reduce their size and weight by optimizing bolt parameters. Additionally, the stiffness of bolted members is very crucial; those with low stiffness may affect the correct functioning of the other connected components. This study focuses on the impact produced by bolt positions, specifically their center of gravity and spacing among them, on the stiffness of angular L-shaped brackets using Finite Element Analysis. Bending and torsional loads were applied to the free end of the member and deformations were recorded under these loads. The results revealed that a triangular bolt pattern is recommended for three bolts, whereas for four or more bolts, the pattern should be uniform to avoid stress concentrations. Moreover, the center of gravity and bolt spacing have a significant impact on stiffness. By optimizing bolt spacing and the center of gravity, a combination of six bolts can be replaced with four bolts of the same size while maintaining the same stiffness
Recent trends in recycling and reusing techniques of different plastic polymers and their composite materials
No full textThe rising environmental concerns caused by the excess use of synthetic materials have diverted the world's attention towards sustainable materials along with a circular economy approach using recycling routes. Nowadays, composite materials have been enormously utilized in different industrial sectors, thus, causing serious accumulation of plastic waste in the environment. The end-of-life (EOL) treatments for plastic composites are imperative as these materials cannot be easily disposed of. The recycling methodologies adopted for polymer composites have two major advantages. Firstly, recycling techniques control plastic composite waste consumption. Secondly, the energy required in the recycling of plastic composite materials is quite low, compared to conventional manufacturing techniques. In this review, we highlight some recent recycling and reusing techniques adopted for plastics and their composite materials. Among all the reported recycling techniques for polymer composites, thermal recycling is best suited for the recycling of carbon fibers (CFs) and glass fibers (GFs). Through thermal recycling, the properties of recycled materials can meet the properties of virgin materials and energy is significantly lower than chemical recycling. However, mechanical recycling requires very low energy for the recycling of composites as compared to the other recycling process. It was concluded that the composite materials consumption in different industries would only be justified when recycling and reusing of composites should be given equal consideration. Additionally, the recycling of polymer composites will boost the circular economy.</p
Recycling of wind turbine blades through modern recycling technologies: a road to zero waste
No full textWind is a clean, efficient, fastest-growing, renewable energy source, which is extensively applied for power generation. The expected design lifetime of a wind turbine lies between 20 to 25 years and requires decommissioning at its end-of-life (EOL) stage. In recent years, the global trend is shifted towards power generation through wind turbines and has globally increased the decommissioned wind turbine blades (WTBs). Compared to other components of wind turbines, it is not convenient to recycle the carbon/glass fiber-reinforced composite-based WTBs, due to their complicated nature and inhomogeneity. Additionally, it is extremely harmful to landfill or incinerate WTBs, as these strategies may result in severe health and environmental issues. Consequently, recycling of WTBs is a viable pathway for the renewable energy sector that ensures the sustainability of wind turbines. To date, only 80% - 85% of the wind turbine materials can be recycled but have potential to reach at 100 % through proper attention required on recovery of all wind turbine materials and adaptation of circular economy (CE) models. The motivation behind this review is to emphasize the importance of sustainable options to treat WTB wastes and minimize the utilization of conventional EOL approaches such as landfilling and incineration. This review also shed lights on the current research and development (R&D) projects, which are related to the adaption of various hybrid recycling technologies and CE models. Moreover, this review also highlights current challenges and future developments of WTB composites. It is concluded that consistent and collaborative efforts should be made by each of the individuals, such as researchers, policy makers, and legislative and industrialist stake holders to improve the viability and effectiveness of the wind energy.</p
