“…Considerations involve FL as unintentional reduction of food available for human consumption as a result of inefficiency in the production and supply chain, and FW to the intentional disposal of food items, particularly by retailers and consumers (CEDES 2018 ). Groups can also be divided into food losses (during processing); unavoidable (perish during the consumption stage, e.g., husks and pits); and avoidable (suitable for food, but wasted in the period of human consumption) (Ahmad et al 2021 ) (Table 1 ).…”

“…For Laudes Foundation ( 2021 ), the domestic uses such as forage, animal bedding, mulch, and compost use a small part of the waste. Among the benefits of using waste materials are the protection and maintenance of natural resources, protection of human health, and reduction in resource extraction (Ahmad et al 2021 ).…”

“…For Ahmad et al ( 2021 ), the advantages of using natural fiber in thermoplastic composites are as follows: (i) biodegradability; (ii) lower greenhouse gas emissions; (iii) availability in variety and format; (iv) job creation in rural areas; (v) non-linear economic development; (vi) efficient and (vii) economical energy consumption. The growing interest in technical lignins, by-products of cellulose, as a polymeric material is also due to their large-scale availability and biodegradability.…”

“…Mustafa et al (2021) highlights that agropolymers from agricultural residues such as starch and cellulose derivatives can be efficiently regulated by natural or chemical mechanisms for the development of green materials, highlighting the use of biofibers in structural performance as a significant reinforcement. Currently, natural fiber reinforcement composites are used in advancing technologies due to their low density, light weight and good mechanical strength, and ecological characteristics (Ahmad et al 2021;Benyus 1997) (Fig. 5).…”

The Brazilian agro-industrial chain generates about 291 million/tons/year of wastes, which, if inadequately destinated, could originate social and environmental risks. There is a growing need for the use of alternative raw materials to replace that originated from fossil resources in the Brazilian industry. Renewable materials play an important role on the sustainability of ecosystems and materials’ circularity. The issue has acquired importance in light of recent bio-based agro-fiber development potential applications. Considering sustainability guidelines, this study aimed to analyze the main Brazilian agro-industrial waste crops (temporary and permanent) as important sources of natural fibers and other raw materials. A systematic review of the literature (SRL) about Brazilian researches, based on concepts of industrial ecology, and the creation of a bibliometric analysis network were carried out. The agricultural biomass related to the main crops presents characteristics making them suitable to be applied for textiles, as natural fibers and polymers, in biosorbents for industrial effluents, and cellulose obtention and reinforcement material in composites. Thus, scientific investment in researches on materials and technology development are necessary to provide applications that could meet current and future demands and expand the scope of new materials for sustainability.

“…Composite materials have become a staple of research and innovation in many engineering fields mainly due to the favourable contrast of their low densities and high mechanical performance when compared to other traditional types of materials [1]. Composites are comprised of a combination of different materials functioning as reinforcement, matrix, and additive in which the aim is to merge the ideal properties of each constituent to form a new and more optimal material [2,3]. One of the types of reinforcement in composites is fibre materials and these can be broadly divided further into two categories: synthetic and natural fibres.…”

Natural fibres are highly desirable in composites as they are renewable, biodegradable, and cost-effective. They are also abundant in nature with many different types available all over the world. However, despite their advantages, key challenges such as poor fibre-matrix interfacial bonding and moisture absorption limit their widespread adoption in more sophisticated applications. This article provides an overview of natural fibres, including classifications, types, properties, advantages, and disadvantages, with a subsequent review of recent studies, focusing on fibre-matrix selection, treatment methods, and characterization to better understand the current situation. It is apparent from these studies that water absorption is a significant challenge due to the inherent hydrophilic nature of natural fibres as even after treatments like mercerization and silane were applied, substantial amounts of absorption were observed. The effects of powder fillers also vary, with beneficial effects up to a certain proportion, beyond which they became detrimental.

Purpose: This study aims to evaluate the efficiency of electro-oxidation as a treatment option for textile effluents containing industrial dyes, with the goal of minimizing their environmental impact. Theoretical framework: The textile industry is known for its high water demand and generation of effluents containing dyes, posing an environmental challenge. Electro-oxidation is a promising technology for the degradation of pollutants that are difficult to mineralize. Method: The treatment process and operational conditions were described, utilizing a Boron-Doped Diamond (BDD) electrode. Three ranges of electric current (6, 12, and 18 mA cm-2) were tested to degrade the Procion Yellow (PY) dye. The removal of the dye, energy consumption, reduction in Chemical Oxygen Demand (COD), Total Organic Carbon (TOC), and effluent toxicity were evaluated. Results and conclusion: The treatment resulted in the removal of 91.4% of the dye, with an energy consumption of 88.4 kWh/m³ for a concentration of 150 mg/L of PY, following a first-order kinetics. Significant reductions in COD (74%) and TOC (85.2%) were observed. The effluent toxicity decreased at currents of 6 and 12 mA cm-2 but increased at 18 mA cm-2. Electro-oxidation proved to be a promising option for treating textile effluents containing industrial dyes. Research implications: The results contribute to the advancement of science and socio-environmental management practices in the textile industry, providing a viable option for effluent treatment and reduction of environmental impact. Originality/value: This study highlights the efficiency of electro-oxidation in the degradation of industrial dyes present in textile effluents, presenting relevant results on dye removal, energy consumption, COD and TOC reduction, as well as the evaluation of treated effluent toxicity.
