“…This behavior may be a consequence of the pistachio shell's stiffness, which results in forming strong modifier aggregates, like those revealed by the fluorescence microscopy analysis (Figure 2d), whichact not only as a filler but also as a reinforcement agent of the modified binder. The improvement in rutting resistance within high temperatures when particles modifiers were added can be attributed to its reinforcing factor, which enhanced the bond strength between asphalt binder particles due to its high surface area [1].…”

“…As a result, the best elastic response before flowing at high temperatures corresponds to the 2 wt.% Jatropha-modified asphalt, while the J4, J6, and J8 samples would be more prone to suffer mechanical failures such as rutting, cracking, or fractures due to thermal changes. The improvement in rutting resistance within high temperatures when particles modifiers were added can be attributed to its reinforcing factor, which enhanced the bond strength between asphalt binder particles due to its high surface area [1].…”

“…Agricultural wastes have been recently studied for asphalt modification; for instance, one of the most evaluated materials for this application is rice husk. Nanometric rice husk particles were found to be easily incorporated into the asphalt, producing environmentally friendly and sustainable binders that showed better performance when exposed to moisture, as well as improved fatigue and rutting resistance [1].…”

In recent years, the use of waste materials from agricultural sources has attracted interest as a research field. Several kinds of waste particles have been studied as additives for asphalt modification, and good results in terms of rheological and physical properties have been discussed in recent literature. In the present work, two types of seed shell particles were evaluated as asphalt modifiers. The shells of Jatropha curcas and pistachio are considered waste materials with no further industrial applications; therefore, in this study, they were incorporated into asphalt at different concentrations in order to evaluate their effect on the binder’s properties. Modified asphalt mixtures were prepared through the hot mix method, and the physical, rheological, and thermal properties of the modified samples were measured and compared to those of the unmodified binder. According to the results of softening point, viscosity, and rheological characterization, the particles obtained from Jatropha curcas and pistachio shells can be used as efficient additives for asphalt modification. Pistachio shell particles act as an asphalt modifier, while Jatropha curcas behaves more like a filler agent since using it at high concentrations causes an inverse effect on the modified performance and properties of the asphalt. Finally, the results obtained showed that both shell particles were useful for improving the binder’s resistance to rutting and permanent deformations, compared to the pure asphalt’s original behavior.

“…Several researchers experimented with the introduction of waste originated from different sources into asphalt mixtures, such as construction and demolition waste (CDW) [2,3], ceramic waste [4,5], waste steel [6], reclaimed asphalt pavement (RAP) [7], plastic waste [8,9], several biomaterials [10,11], and industrial by-products [12,13]. The main goal of these laboratory investigations was to obtain eco-friendly asphalt mixtures that were also sustainable in terms of mechanical properties and durability, so as to minimize maintenance treatments and achieve cost-effective asphalt pavements in the long term.…”

The pursuit of sustainability in the field of road asphalt pavements calls for effective decision-making strategies, referring to both the technical and environmental sustainability of the solutions. This study aims to compare the life cycle impacts of several pavement solution alternatives involving, in the binder and base layers, some eco-designed, hot- and cold-produced asphalt mixtures made up of recycled aggregates in substitution for natural filler and commercial recycled polymer pellets for dry mixture modification. The first step focused on the technical and environmental compatibility assessment of the construction and demolition waste (CDW), jet grouting waste (JGW), fly ash (FA), and reclaimed asphalt pavement (RAP). Then, three non-traditional mixtures were designed for the binder layer and three for the base layer and characterized in terms of the stiffness modulus. Asphalt pavement design allowed for the definition of the functional units of Life Cycle Assessment (LCA), which was applied to all of the pavement configurations under analysis in a “from cradle to grave” approach. The LCA results showed that the best performance was reached for the solutions involving a cold, in-place recycled mixture made up of RAP and JGW in the base layer, which lowered all the impact category indicators by 31% on average compared to those of the traditional pavement solution. Further considerations highlighted that the combination of a cold base layer with a hot asphalt mixture made up of CDW or FA in the binder layer also maximized the service life of the pavement solution, providing the best synergistic effect.

“…These agricultural wastes have a high carbon content and also loosely termed as biomass, which could be used in several products such as biofuels, biochemicals and biomaterials via different biological, chemical and physical approaches (Zakaria et al 2018). Several studies including articles, books and reviews have been reported about these agrowastes based on its evolution and alternative uses (Duque-Acevedo et al 2020), its management (He et al 2019;Fareed et al 2020), its viability as green concrete (Luharet al 2019;Mo et al 2020), it is removing of pollutants as adsorbents (Dai et al 2018), its applications in civil engineering (Nguyen et al 2019), production of biodegradable polymers (Maraveas, 2020), bio-actives (Ben-Othman et al 2020), biofuels (Ge et al 2021), biochar (Kwoczynski and Cmelík 2021;El-Bassi et al 2021) and biogas (Dar et al 2021).…”

Agricultural Waste and its Nano-Management: Mini Review

et al. 2020

A GRICULTURAL wastes are considered residues resulted during the agricultural production and after harvesting fruit and vegetable and their processing, agro-industrial by/co-products from the grapes, banana, olives and milk processing. These wastes may represent a treasure when they are turning into valuable applications (i.e., composts, biochar, adsorbents for removing pollutants from the environment and organic fertilizers) instead of burning it in open fields causing several environmental problems such as soil degradation and air pollution. The landfill disposal and open dumping of agro-wastes is a common practice in the developing countries generating huge amounts of ash, which may create serious health and environmental problems, primarily due to pollution of groundwater. Under the umbrella of the green bioeconomy and based on industrial innovation and high technology, new and better approaches for the recovery of agricultural wastes have been developed. This has contributed to guaranteeing sustainable production and its consumption, resource utilizing efficiency, the conversation of these wastes into valuable products and the reduction of negative environmental impacts.The common management of Agro-wastes may include a lot of suggested uses such as the production of biosynthesis of nanoparticles, biotechnological products, composting and biofuel production. Furthermore, a lot of bioactive compounds could be produced from the agrowastes, which have many application possibilities such as functional food, pharmaceutical and cosmetic approaches. The nano-management of agro-wastes may include using nanotechnology to convert the agro-wastes into a valuable product. This topic still has several open questions, particularly under sustainable and green bioeconomy prespective.
