“…In other words, it is a production-consumption system that involves recycling, refurbishing, or reusing consumer goods for as long as possible. Its implementation, thus, is very likely to reduce the cost and save energy to produce certain products [45]- [47]. Implementing a circular economy during the pandemic is estimated to reduce the final energy use by 1.6 mtoe, CO2 emissions by 3.8 mt, and PM2.5 emissions by 229 t. Accumulated until 2040 (from 2020), implementing a circular economy would save final energy use and CO2 emissions by 9.1 mtoe and 17.6 mt [48] and improve the energy security index [49].…”

This study reviews the impact of the COVID-19 pandemic on environmental health through the energy sector, based on the close relationship between energy, the economy, and the environment. The lockdown policy to contain the spread of the disease has hampered the global economy. Due to the close relationship between energy and the economy, the decline in global economic growth can be easily indicated by the decrease in world energy consumption. However, this study argues that this situation also opens the opportunity of restoring environmental health. Thus, the objective of the study is to find the opportunity and the lesson that can be learned from the COVID-19 pandemic. This study employs a qualitative method that combines descriptive analysis and literature review. It involves a review, processing, and observation of quantitative data (statistics) and qualitative data. This study finds that the pandemic opens opportunities to relieve the environment damaged by fossil-dominated energy consumption to pursue economic growth. However, this study also finds the challenge to overcome and lesson learned. The challenge is the two-way pressure from demand and prices that renewables must face. The lesson to be learned is mainly to reduce the dependency on fossil energy sources, primarily if it is imported. However, on top of that, the government must be able to seize the opportunities to overcome the challenge. Thus, this study is expected to provide an optimistic view of taking advantage of the blessing in disguise of the pandemic to rehabilitate environmental health through the energy sector.

“…Normally, this type of composite is used in these industrial sectors due to their high performance, such as high specific stiffness and strength . CFRP final properties are strongly linked to diverse parameters such as fiber content, orientation, or the selected manufacturing process. , In this way, focused on structural parts, the use of preimpregnated fibers, so-called prepregs, is one of the most well-known methods to develop high-performance CFRPs. Parts made from prepregs present unique features, such as high fiber volume content and relatively easy manufacture .…”

The continuous growth in the use of preimpregnated semielaborated products to manufacture continuous carbon fiber-reinforced polymer parts has led the industry to face an important challenge in the management of the prepreg scrap, as the amount of waste produced can reach almost 75% due to the inefficiency of the cutting phase. In this context, this industry is pushed to move toward a circular economy approach by conferring a new use to their waste. The main problem arises from the fact that shortening carbon fiber leads to nonefficient mechanical reinforcement and that other thermal or chemical recycling approaches are environmentally hazardous. In this work, mechanical recycling of carbon fiber prepregs from expired virgin prepregs or scrap from an automated manufacturing operation is proposed as an economical and environmentally efficient method to obtain multifunctional coatings with Joule effect heating capabilities, which are demanded by different industries as a high-value product. As a coating, mechanical performance is not so relevant; nevertheless, obtaining high electrical conductivity by the incorporation of proper size and distributed short recycled carbon fiber can lead to a self-heating coating that could be used for anti- and deicing purposes or any other thermally activated function with very low power consumption. In this way, electrical conductivities up to 2 S/m were obtained, which allowed for achieving temperatures of 200 °C by the Joule effect in all samples in less than 17 s by the application of voltages below 48 V for bulk materials and 100 V for the coating.
