Data on environmental analysis of natural antioxidant production from walnut husk by a solar photovoltaic-driven system as a replacement for potentially carcinogenic synthetic antioxidants

Abstract

In order to develop a product sustainably, multiple analyses, including comprehensive environmental assessment, are required. Solar-assisted production of walnut husk methanolic extract (WHME) as a natural antioxidant for biodiesel was scrutinized by using the life cycle assessment (LCA) approach. More specifically, the environmental sustainability of WHME antioxidant was evaluated and compared to that of propyl gallate (PG), the most widely used synthetic biodiesel antioxidant, under two scenarios. Additionally, supplementary files including the inventory data consisting of raw data as well as elementary flows, mid-point, and end-point categories are presented. The analysis of scenarios revealed that the use of the natural antioxidant and the avoidance of the chemical antioxidant in biodiesel fuel could be regarded as an eco-friendly approach substantially enhancing the environmental friendliness of biodiesel in particular in terms of human health. Furthermore, given the waste-oriented nature of WHME, the scenario involved its application could serve as a promising strategy to simultaneously valorize the agro-waste and generate a value-added product; a move toward implementing the circular economy approach in the biodiesel industry.

Pehuén (Araucaria araucana) seed residues are a valuable source of natural antioxidants with nutraceutical, chemoprotective and metal corrosion-inhibiting properties

“…Piñón samples were prepared for analysis following the methodology and procedures detailed in previous work [37,38]. Spectral data were obtained at four different voltages (10,20,40, and 50 KV) to properly excite and determine elemental composition from sodium (n = 11) to lead (n = 82). Evaluation of EDXRF spectra and calculation of elemental concentrations were performed using the software supplied with the equipment.…”

“…In particular, vegetable sources are being intensely studied for their preventive and therapeutic uses in cancer, Parkinson's, Alzheimer's, atherosclerosis, liver injury, rheumatoid arthritis, type 2 diabetes, neurodegeneration, kidney failure and aging, and also as chemoprotective agents in cancer therapy [4][5][6][7][8]. In addition, these compounds have increased industrial applications; for example, they are used as ingredients in the formulation of dietary supplements, as reservatives for food and cosmetics, and to prevent the degradation of rubber and oil-derived compounds [9,10]. Furthermore, many vegetable antioxidants are being investigated as green inhibitors for corrosion protection of metals and alloys [11,12].…”

Assessing the environmental impacts of furfural production in a poplar wood biorefinery: A study on the role of mannitol concentration and catalyst type

“…These results were in line with the findings of most studies conducted on biorefinery-based products. For example, In the study by Khounani et al [53,74], higher electricity consumption in synthetic antioxidant (propyl gallate) synthesis was one of the main contributors to human health and ecosystem quality damage categories. Likewise, another research ascertained that electricity, direct emissions of process, and ash landfill resulting from organosolv treatment of wheat straw biorefinery led to approximately 75-100% of the environmental impacts across all the impact categories [18].…”

Impact and performance efficiency analysis of grid-tied solar photovoltaic system based on installation site environmental factors

“…11 Multiple assessments, including a full environmental evaluation, are required to produce a product in a sustainable manner. 12 Photovoltaic panels convert a very small amount of almost 5-25% of solar energy into electricity depending on photovoltaic panel efficiency while the rest 75-95% of incident energy is converted into heat. 13 This heat increases the core temperature of a photovoltaic panel.…”
