Development of bioactive films and food coverings from renewable resources has major advantages for reducing reliance on plastic materials increasing the shelf life associated products. This study assessed development such covering using combined alginate fucoidan extracted brown seaweed Ascophyllum nodosum. A solvent containing glycerol choline chloride was used to extract before sodium carbonate extraction. The contained approximately 42.2% as a substitution when developing through 0, 50...

Recently, second-generation (non-vegetable oil) feedstocks for biodiesel production are receiving significant attention due to the cost and social effects connected with utilising food products of energy products. The Beauty leaf tree (Calophyllum inophyllum) is a potential source non-edible oil producing because its suitability in an extensive variety atmospheric condition, easy cultivation, high fruit rate, content seed. In this study, was extracted from seeds through three different...

In recent years, the beauty leaf plant (Calophyllum Inophyllum) is being considered as a potential 2nd generation biodiesel source due to high seed oil content, fruit production rate, simple cultivation and ability grow in wide range of climate conditions. However, however, free fatty acid (FFA) content this oil, feedstock still unrealized, little research has been undertaken on it. study, transesterification produce investigated. A two-step conversion method consisting catalysed...

In this study, lignin from acid-catalyzed glycerol (AG) pretreatment of sugarcane bagasse was recovered and characterized. Its effects on enzymatic hydrolysis cellulase recycling were then investigated. Prior to recovery, a two-step dilute acid AG used deconstruct bagasse, which led glucan digestibility 99%, glucose yield 91%, xylose 67%. Following hydrolysis, lignin-rich residues by simple filtration at 63% purity 90%. Two-dimensional heteronuclear single quantum correlation nuclear...

The livestock sector is a fundamental part of the modern global economy and provides food, clothing, furnishings, various other products. So as to ensure its resilience changes in consumer expectations, cost production, environmental sustainability, must shift circular model. Current strategies recover value from wastes low-value co-products industries yield limited value; hence, new technologies are required upgrade co-products, generate high-value products that can feed into chain....

Gasification of lignocellulosic biomass can be used to produce syngas as a biorefinery feedstock. To facilitate the commercialisation gasification process, models are predict outputs, simulate impacts irregular circumstances, and analyse process feasibility. This paper presents hybrid model combining Aspen Plus machine learning (ML) algorithms enhance prediction outputs. A base case flowsheet simulation was implemented in based on assumed thermodynamic equilibrium conditions which lead...

Over the past few decades, biodiesel produced from oilseed crops and animal fat is receiving much attention as a renewable sustainable alternative for automobile engine fuels, particularly petroleum diesel. However, current production heavily dependent on edible oil feedstocks which are unlikely to be in longer term due rising food prices concerns about durability. Therefore, there an urgent need researchers identify develop overcome disadvantages of ones. On other hand, artificial neural...
