Poly(lactic acid) (PLA)/poly(butylene succinate adipate) (PBSA) films with Micro fibrillated cellulose (MFC) and cardanol for packaging applications

Micro Fibrillated Cellulose (MFC) has emerged as a promising component in film formulations due to its unique barrier prope.rties. In this study, to best of our knowledge, cardanol, a biobased plasticizer derived from cashew processing, was employed for the first time, as a dispersing aid for MFC, during a liquid assisted extrusion technique with a Poly(lactic acid) (PLA)/Poly(butylene succinate adipate) (PBSA) blend. The aim of the work is the production of PLA/PBSA/MFC films for packaging applications. The addition of different MFC amount was investigated (added at 0.5, 0.75 and 1 wt.% concentrations). The results obtained are very interesting, in fact from one hand Cardanol improved the compatibility between PLA and PBSA and avoided the MFC agglomeration. On the other hand, micro fibrillated cellulose ensured a stable film blowing and the achievement of enhanced barrier properties, seal ability and mechanical resistance. In particular, the best result was obtained with an MFC content of 0.75 wt.% for which a good compromise in terms of films ductility, barrier properties and seal ability was achieved.

A Study on Technological Advancements in Cashew Processing Machines in India

This article theoretically analyses about the “A Study on Technological Advancements in Cashew Processing Machines in India.” In addition to being a significant cash crop, cashew is one of the most valuable processed nuts traded on the world's commodity markets. Cashew is grown on 9,23,000 hectares of land in India, where it produces 613,000 MT and has a productivity of 0.7 MT/ha. With a 32.3% share, Maharashtra leads the nation in cashew output. For its kernels, it is extensively grown across the tropics. It is produced in a few plain regions of Karnataka and Madhya Pradesh as well as on the east and west coasts of India. In Maharashtra, productivity is shown to be the highest. With a 25.52% global output share, India is the world's biggest cashew producer. About 230 kg (23%) are created for every metric ton of raw cashew seed produced and processed in India. This study employed frameworks such as the SWOT and PEST analyses to analyses market trends. Though India is one of the leading producers of cashew, still they were using one of the traditional methods to processing the cashew nuts. The study enhances about the marketing strategies which should be followed to develop the cashew processing machines in India.

Biochar from cashew residue enhances silicon adsorption and reduces cohesion and mechanical resistance at meso- and micro-structural scales of soil with cohesive character

Horizons with cohesive character impose physical restraints on plant development, particularly when it occurs near the soil surface. Howbeit, the genesis of cohesive character in soils is associated with temporary and reversible cementation by amorphous silica. Thus, we hypothesized that the biochar obtained from residues from cashew processing would improve soil porosity and promotes silicon adsorption, consequently reducing cohesion and mechanical resistance while improving the physical quality of soils with cohesive character. We collected soil samples with deformed structure from the Bt1 horizon of a Typic Haplustult with cohesive character in northeast Brazil. These samples were used to prepare test substrates by combining air-dried and sieved soil samples and biochar at application rates of 0, 5, 10, 20, and 40 Mg ha−1. All the samples in each treatment underwent ten cycles of wetting and drying (one cycle per week) to allow the manifestation of the cohesive character. Subsequently, we assessed silicon adsorption capacity, soil bulk density, porosity, soil penetration resistance, tensile strength, and rheometric properties. In the 5 and 10 Mg ha−1 doses, the physical quality remained like the control treatment (0 Mg ha−1). The 20 and 40 Mg ha−1 doses resulted in increased soil silicon adsorption capacity (+7.6 and +15.3%, respectively), total porosity (+2.0 and +1.9%, respectively), and macroporosity (+14.6 and +15.3%, respectively), compared to the treatment without biochar. Conversely, these doses led to a reduction in soil bulk density (-0.1 and −0.8%, respectively), penetration resistance (-16.2 and −16.1%, respectively), tensile strength (-24.2 and −36.5%, respectively), deformation at the end of the linear viscoelastic range (-6.3 and −10.5%, respectively), shear stress at the end of the linear viscoelastic range (-16.4 and −26.9%, respectively), and maximum shear stress (-13.7 and −22.3%, respectively). In conclusion, the application of biochar improved soil porosity and promoted silicon adsorption, thus reducing the bulk density, cohesion, and mechanical resistance, enhancing the physical quality of soils with cohesive character, especially for doses of 20 and 40 Mg ha−1.

Development of cashew apple bagasse based bio-composites for high-performance applications with the concept of zero waste production

This study suggests a comprehensive concept for using waste generated from the cashew processing industry in the production of some functional and high-performance bio-composites. Cashew apple bagasse (CAB), cashew nut shell (CNS), and cardanol were used as primary feedstock. Cardanol was used to synthesize cardanol-based benzoxazines that were used as resins. CAB was used to prepare carbon and ash that were used as filler materials in preparing the composites. Thus, three ingredients (resins, carbon, and ash) were obtained, while the CAB and CNS were used directly as feedstock. Firstly, a high-performance CAB-filled panel board composite was prepared as an acoustic barrier, and sound absorption coefficients value of 0.8 at 3000 Hz and 0.7 at 6400 Hz were achieved. Secondly, CNS and CAB were used at different ratios to prepare fuel briquettes, and findings reveal that the briquettes have a calorific value and an ash content of 5225 cal/g and 7%, respectively. Lastly, CAB, carbon, and ash were employed as filler materials in the production of a friction composite, which was found to have a friction coefficient and wear rate of 0.59 and 0.77 × 10−10 cm3/Nm respectively. Overall, this study suggests the concept of zero waste production, as waste from the cashew processing industry was successfully used to produce composite materials for use as acoustic barriers and fuel briquettes. While the ash produced as a waste after using fuel briquettes served as filler material in the production of a robust friction composite.

Cashew By-Product as a Functional Substrate for the Development of Probiotic Fermented Milk.

Cashew (Anacardium occidentale) processing generates a by-product (CB) with potential for health benefits and that could be a favorable ingredient to be added to a probiotic food matrix. This study aimed to assess the functional attributes of CB in fermented milk with a probiotic and a starter culture using in vitro gastrointestinal conditions. Two formulations were tested, without CB (Control Formulation-CF) and with CB (Test Formulation-TF), and the two strains most adapted to CB, the probiotic Lacticaseibacillus paracasei subsp. paracasei F19® and the starter Streptococcus thermophilus ST-M6®, were chosen to be fermented in the CF and the TF. During a 28-day period of refrigeration (4 °C), both strains used in the CF and TF maintained a population above 8.0 log CFU/mL. Strains cultured in the TF had a significant increase in total phenolic compounds and greater antioxidant potential during their shelf life, along with improved survival of F19® after in vitro-simulated gastrointestinal conditions. Our study revealed the promising potential of CB in the probiotic beverage. The CB-containing formulation (TF) also exhibited higher phenolic content and antioxidant activity. Furthermore, it acted as a protector for bacteria during gastrointestinal simulation, highlighting its potential as a healthy and sustainable product.

Cashew nut shell oil as a potential feedstock for biodiesel production: An overview.

Biodiesel outperforms diesel in emissions and engine performance. They burn efficiently in diesel engines and are eco-friendly.

Cashew processing in Ghana – A case for infant industry support?

West Africa produces almost half of the world's cashew nuts. With the domestic cashew processing industry still in its infancy, however, most of it is exported as raw material and processed in India and Vietnam. In Ghana, this is provoking discussions about market interventions to support domestic processing. Since different price policies have diverging implications for farmers and processors, the choice of the policy instrument leads to conflicts of interest between the two groups. In this study, we analyse the short- and long-term economic impacts of enhancing cashew processing through (i.) a temporary export tax on raw cashew nuts, (ii.) a temporary subsidy to cashew processors, and (iii.)a temporary export tax on raw cashew nuts, with government revenues passed on to cashew growers. For this purpose, we develop a partial equilibrium model for the Ghanaian cashew market including the processing from raw cashew nuts to kernels. We find that in the short run, all price policies lead to a substantial increase in processing at the expense of net welfare. We argue, however, that the sector may experience productivity gains through learning by doing and thus, after price policies are phased out, stick to its increased level of output such that short-term welfare losses could be recouped. Therefore, temporarily introduced price policies could help the infant cashew processing industry to grow up, promote the development of the domestic cashew sector, and be welfare-enhancing in the long run. A subsidy to processors is the most appropriate option to achieve this.

Physical and mental morbidity pattern among female cashew workers in Kollam district, Kerala

Background: The cashew processing is a labour-intensive work with a significant number of female workers. Majority belong to low socioeconomic status and so they join this sector to meet up their daily living.

Characterization of slow pyrolysis products from three different cashew wastes

A huge amount of waste is generated by the cashew processing industries. This study aims to valorise these cashew wastes generated at different levels while processing cashew nuts in factories. The feedstocks include cashew skin, cashew shell and cashew shell de-oiled cake. Slow pyrolysis of these three different cashew wastes was performed at varying temperatures (300-500℃) at a heating rate of 10℃/min in a lab scale glass-tubular reactor under inert atmosphere of nitrogen with flow rate of 50 ml/min. The total bio-oil yield for cashew skin and the de-oiled shell cake was 37.1 and 48.6 wt% at 400℃ and 450℃, respectively. However, the maximum bio-oil yield obtained for cashew shell waste was 54.9 wt% at 500℃. The bio-oil was analysed using GC-MS, FTIR, and NMR. Along with the various functionalities observed in bio-oil through GC-MS, phenolics were observed to have maximum area% for all the feedstocks at all temperatures. At all the slow pyrolysis temperatures, cashew skin led to more biochar yield (40 wt%) as compared to cashew de-oiled cake (26 wt%) and cashew shell waste (22 wt%). Biochar was characterized by various analytical tools such as XRD, FTIR, Proximate analyser, CHNS, Py-GC/MS and SEM. Characterization of biochar revealed its carbonaceous and amorphous nature along with porosity.

Structural, molecular and thermal properties of cardanol based monomers and polymers synthesized via atom transfer radical polymerization (ATRP)

Cardanol, a byproduct of the cashew processing industry, has been widely studied feeedstock for sustainable monomers and polymers. In this article, the Atom Transfer Radical Polymerization (ATRP) of three radically polymerizable monomers, namely, cardanyl acrylate (CA), hydrogenated cardanyl acrylate (PA) and hydrogenated cardanyl methacrylate (PMA), was studied. The monomers as well as the polymers were structurally characterized and studied by differential scanning calorimetry (DSC) to understad their thermal behavior. The PA monomer showed melting (Tm) at 35 °C and crsytallization (Tc) at −3.27 °C. The synthesized polymer shows Tm of 16.5 °C and the Tc increased to 7.2 °C. In PMA monomer, the Tm was observed at 15.21 °C and Tc at −11 °C and the correponding values for the polymer decreasing to 1 °C and −18 °C, respectively. The coressponding transitions of CA monomer and its polymer were broad and less defined. The homopoymerization of CA and PMA yielded good conversions but the PA polymer yield was low under identical conditions, probably due to the higher monomer crystallinity of PA. The effect of different ATRP ligands, viz, pentamethyldiethylenetriamine (PMDETA) and bipyridine (dNbpy), on the conversion, molecular weight and polydispersity was also investigated.

Synthesis and Characterization of Partially Biobased Aromatic (Co)polycarbonates Containing Biphenylene Units and Pendant Pentadecyl Chains

Abstract2‐Pentadecyl‐[1,1”‐biphenyl]‐4,4”‐diol (PBD) is synthesized starting from cashew nut shell liquid—a by‐product of cashew processing industry. A new series of partially biobased aromatic (co)polycarbonates possessing biphenylene units and pendant pentadecyl chains is synthesized by solution polycondensation of PBD or varying compositions of PBD and bisphenol‐A with triphosgene in dry dichloromethane. Inherent viscosities and number average molecular weights of (co)polycarbonates are in the range 0.51–1.24 dL g−1and 18 × 103– 43.4 × 103 g mol−1, respectively indicating the formation of reasonably high molecular weight polymers. Flexible, transparent, and free‐standing films of (co)polycarbonates can be cast from chloroform solution. (Co)polycarbonates are characterized using Fourier transform infrared spectroscopy (FTIR),1H NMR,13C NMR spectroscopy, X‐ray diffraction (XRD), differential scanning calorimetry, and thermogravimetric analysis.T10andTgvalues of (co)polycarbonates are in the range 417–433 and 8–147 °C, respectively. It is demonstrated that theTgvalues can be tuned by incorporation of appropriate mol% of PBD as a comonomer in Bisphenol‐A‐based copolycarbonates. The lowering of theTgvalues of (co)polycarbonates can be attributed primarily to the packing disruptive effect of flexible pentadecyl chains. Furthermore, the effect of incorporation of PBD as a comonomer on water contact angle values of (co)polycarbonates is evaluated.
