The effect of MicroRNAs on the insecticide resistance mechanism in populations of the pistachio psyllid Agonoscena pistaciae, a pest of pistachios
The pistachio psyllid, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Psyllidae), is a major pest of pistachio orchards in Türkiye, particularly in regions with intensive pistachio cultivation. Despite repeated pesticide applications, psyllid population density and the associated damage continue to persist in many orchards. This situation suggests the possible development of resistance to commonly used pesticides. […]
Bio-Epoxy Composites Formulation Using Bio-Oils from Walnut and Almond Shell Pyrolysis: Influence of Temperature on Chemical Composition and Curing Behavior
In this study, we develop bio-epoxy composites incorporating bio-oils obtained from the pyrolysis of almond and walnut shells at 400 °C and 600 °C, with the aim of evaluating their potential as renewable precursors for epoxy resin modification. The influence of pyrolysis temperature on bio-oil yield and chemical composition is examined to identify phenolic-rich fractions […]
Sustainable plant-based milk analogs from pistachio, lupin and almond: a zero-waste approach with improved quality attributes
The growing demand for plant-based foods is driven by health, sustainability, and consumer preferences. In the case of developing dairy alternatives, it requires innovative and sustainable approaches. This study investigates the production of plant-based milk analogs from pistachio, almond, and lupin to develop plant beverage formulations suitable for subsequent production of fermented dairy analogs through […]
Exploring the bioherbicide and in vitro biofungicide effects of pistachio hulls for their use in sustainable agriculture
Agriculture requires sustainable approaches for effective weed management reducing the negative consequences of synthetic herbicides. In this context, some agricultural by-products such as pistachio hulls could be considered as source of biopesticide compounds due to their allelopathic effect. The application of pistachio hull extract and powder produced an allelopathic effect against the weeds Solanum nigrum, […]
Valorization of Pine Nut Shells in Polypropylene and Low-density Polyethylene Composites
The pine nut industry generates a high amount of residues, currently under-valorized in most cases as energy production through incineration. A more effective end-of-life option involves using pine nut shells in polymeric composites, since they represent a source of valuable compounds, such as polysaccharides, lignin, and polyphenols. In the current study, composites were prepared by […]
Spent Lithium-ion Battery Recycling: the Thermodynamics and Kinetics Process of NCM Cathode Materials Reduced with Hazelnut Shells Via the Coats-Redfern Method
The reduction of NCM cathode materials by waste biomass is currently a hot topic in the field of energy recovery. In China, large quantities of hazelnut shells are discarded every year, which, if as a reducing agent, can achieve the eco-friendly goal of “treating waste with waste”. While there is currently a lack of comprehensive […]
Rethinking the ageing process of spirits: Nutshells as a sustainable alternative to wood
Aguardente bagaceira, a Portuguese grape marc spirit (GMS), represents an opportunity for sustainable innovation in ageing process. This study investigates the use of nutshells (almond, hazelnut, walnut, chestnut) as alternative ageing materials to conventional wood. Spirits were aged for six months in 20 L stainless steel vessels (50 g/L, chestnut tested at 12.5 and 25 […]
Sustainable Carbon Source from Almond Shell Waste: Synthesis, Characterization, and Electrochemical Properties
This study demonstrates the complete transformation of almond shell waste into a high-performance carbon material for carbon paste electrode (CPE) fabrication. The biocarbon was synthesized via carbonization at 800 °C and subsequently activated with CO2, resulting in a semicrystalline structure rich in carbonyl groups-consistent with its lignocellulosic origin (34.25% cellulose, 13.48% hemicellulose, 48.03% lignin). Carbonization […]
Valorization and Environmental Impacts of Pecan Waste: A Critical Review
Pecan (Carya illinoinensis) cultivation generates a substantial number of byproducts, particularly nutshells, which are often discarded despite being rich in bioactive and structural compounds. These agro-industrial residues, comprising nearly 50% of the total nut mass, contain high levels of phenolics, flavonoids, dietary fiber, and lignocellulosic matter, making them suitable for circular economy applications. This review […]
Development of Antioxidant Polycaprolactone Films Incorporating Peanut Skin Food Waste Extract for Active Packaging
Biodegradable polycaprolactone (PCL) films were developed with 13% w/w ethanol extract from industrial peanut skin residues (PSE), a rich source of natural antioxidants and antimicrobials. Films retain actives during processing. Antioxidant activity was evaluated via total phenolics, flavonoids, condensed tannins, and radical scavenging assays (DPPH, ABTS). PSE incorporation enhances oxidative thermal stability, increasing oxidation onset […]
