“…However, improving the economics of conversion technologies is a key step towards the sustainability of the valorization steps that are being proposed [63]. One of the applications that has undergone significant technological development in the last few years is the green chemistry around biomass conversion into liquid fuels and bio-asphalt through bio-oil production [64][65][66]. This example should be generalized for the valorization of GCM/GCN.…”

Green carbon-based materials (GCM), i.e., carbon materials produced using renewable biomass or recycled waste, ought to be used to make processes sustainable and carbon-neutral. Carbon nanomaterials, like carbon dots and the nanobichar families, and carbon materials, like activated carbon and biochar substances, are sustainable materials with great potential to be used in different technological applications. In this review, the following four applications were selected, and the works published in the last two years (since 2022) were critically reviewed: agriculture, water treatment, energy management, and carbon dioxide reduction and sequestration. GCM improved the performance of the technological applications under revision and played an important role in the sustainability of the processes, contributing to the mitigation of climate change, by reducing emissions and increasing the sequestration of CO2eq.

“…The generation of a representative molecular model is essential for the MD simulations of materials. ,,− The composition of asphalt is complex with nearly one million molecules; asphalt is mainly composed of hydrocarbons, oxygen, nitrogen, sulfur, and other heteroatoms, and metal atoms including nickel, iron, vanadium, etc . The molecular model of asphalt can be established by the assembly method and average molecular method.…”

During the last few decades, industrial waste has increased at an alarming rate, and the recycling of waste materials has always been an urgent problem to be solved. While the number of vehicles per citizen has dramatically increased, as well as the traffic loading, limiting the deterioration of the pavement networks is an approach, and it can be achieved by the addition of polymers to asphalt binders and mixtures. Waste polymers are used in asphalt due to their low cost and environmental friendliness. Both asphalt and polymeric materials are complex in structure, and it is difficult for researchers to quickly and clearly understand the properties of the materials and how they change. Multiscale research approaches effectively improve the understanding of materials with macroscopic/experimental data and microscopic simulations. The Molecular Dynamics (MD) method is employed to analyze material properties from a nanoscale perspective, and it is one of the most powerful and effective tools to understand fluid and material behaviors at an atomic level. This work aims to review the application of waste materials to asphalt materials based on the MD method. A brief description was demonstrated for the model generation and property analysis of modeling asphalt molecules and waste polymer-modified asphalt, especially electronic waste materials, as well as recycled asphalt pavement (RAP) and thermoplastics. Moreover, the advantages and disadvantages of MD simulation methods were extensively discussed for the application of waste materials in engineering materials. The review may provide a more comprehensive understanding of related projects and guide subsequent research for readers.
