Natural And Synthetic

The global textile business is now gearing towards greener alternatives to combat pollution and avoid synthetics in production. Ironically, there is an increased awareness among consumers on the quality of the product and choices they make in their shopping. The natural and synthetic fibres have set limitations, which has made manufacturers look out for other alternative fibres. Bamboo, banana, milk, and corn are experimented for its commercial capabilities to perform as a textile material. To add on to the list, orange, the popular, and the most preferred fruit are known for its refreshing flavour. The peels after consumption/ processing of the fruit are discarded in the landfill, which is an organic waste with immense potential.  This paper details the successful brand ‘Orange fibre’, its journey from scratch, and the properties of textiles made from processing orange peel waste. The current areas of research have also been covered in a brief way, to invite more scholars to create solutions for the hitherto pollution orange peel waste.

Environmentally Friendly Process

This study uses orange peel waste to create a biopolymer that can be used for different purposes. In order to achieve this, we evaluated various technologies for the production of the biopolymer, and tried to design the most environmentally friendly process possible. One of the reasons why this bioplastic should be manufactured is to participate in the replacement of common environmental hazardous plastic, which has been banned in many places. On the other hand, using orange peel as the main ingredient is an alternative and gives value to an organic waste that has limited use in circular economy solutions. In this research we present a methodology to create a bioplastic of orange peels. As a result, we obtained a biodegradable, flexible and resistant material to be used in the manufacture of containers, utensils, etc. In addition, it is a material that, given the raw materials used, is considered GRAS (Generally Recognized As Save), implying a non-toxic product that is safe for the consumer.

The industrialization process of oranges generates waste, which is inadequately disposed of; this produces adverse effects on the environment. Among the alternatives for valorization is the vermicomposting process, which consists of the degradation of organic waste through the action of earthworms and microorganisms. Therefore, this research aimed to study this process using orange peel (OP) waste at the laboratory level. For this purpose, it was necessary to determine the degradation conditions through the monitoring of physicochemical parameters (temperature, pH, humidity, organic matter (OM), total organic carbon (TOC), total nitrogen (TN) and the carbon/nitrogen (C/N) ratio). To balance the substrate’s nutrients, load material (LM) that included vegetable waste and eggshells was added to three different mixtures: M1 (50% OP + 50% LM), M2 (40% OP + 60% LM) and M3 (60% OP + 40% LM). To condition the substrate for earthworm (Eisenia fetida) activity, a previous precomposting process was performed. The results showed that all the mixtures fulfilled the requirements for a quality and mature vermicompost; however, the highest concentrations for TN were in the mixtures M1 and M2. The total time required for degradation of the OP waste was 13 weeks.

Aims: Computational modelling may help us to detect the more important factors governing this process in order to optimize it. Background: The generation of hazardous organic waste in teaching and research laboratories poses a big problem that universities have to manage. Methods: In this work, we report on the experimental measurement of waste generation on the chemical education laboratories within our department. We measured the waste generated in the teaching laboratories of the Organic Chemistry Department II (UPV/EHU), in the second semester of the 2017/2018 academic year. Likewise, to know the anthropogenic and social factors related to the generation of waste, a questionnaire has been utilized. We focused on all students of Experimentation in Organic Chemistry (EOC) and Organic Chemistry II (OC2) subjects. It helped us to know their prior knowledge about waste, awareness of the problem of separate organic waste and the correct use of the containers. These results, together with the volumetric data, have been analyzed with statistical analysis software. We obtained two Perturbation-Theory Machine Learning (PTML) models including chemical, operational, and academic factors. The dataset analyzed included 6050 cases of laboratory practices vs. practices of reference. Results: These models predict the values of acetone waste with R2 = 0.88 and non-halogenated waste with R2 = 0.91. Conclusion: This work opens a new gate to the implementation of more sustainable techniques and a circular economy with the aim of improving the quality of university education processes.

A 3-year study was undertaken to establish the effect of field nutritional sprays, combined with insecticide treatments or not against Asian Citrus psyllid, on the fruit quality of ‘Valencia’ orange trees affected by the greening disease Huanglongbing (HLB). Four replicated plots were harvested, juiced, and pasteurized. Nine to twelve trained panelists evaluated the juice using seven flavor, five taste, four mouthfeel and three aftertaste descriptors. There was little difference between treatments in 2013; only orange peel flavor and bitterness were significantly lower for the insecticide treatment. In 2014, positive attributes, such as orange and fruity flavor, sweetness and mouthfeel body, were significantly higher in the insecticide treatment. Sourness was highest in untreated control, and there were no differences between treatments for bitterness. In 2015, negative attributes, such as grapefruit, orange peel and typical HLB flavor, sourness, bitterness, and astringency, were significantly higher in untreated control fruit, suggesting perhaps that the beneficial effect of nutritional and insecticide treatments was cumulative, only manifesting on the 3rd year of the study, and or because of the progression of the disease affecting untreated controls. Data are discussed in relation to juice chemical composition, including volatiles, sugars, acids, limonoids, and flavonoids, adding to the fundamental knowledge concerning chemical drivers of orange flavor.

AbstractThe purpose of this study was to know the quality of Boer liquid semen during storage by adding sweet orange essential oil and gentamicin into the tris yolkextender.The semenlongevity test was carried out by storing semen in a closed tube at room temperature and refrigerator, and evaluated motility and Viability every 3 hours at room temperature and 12 hours in refrigerator. The results showed that the characteristics of the liquid semen, with the addition of 1% of essential oils showed percentage of motility and Viability significantly higher than 0.5% and without the addition of essential oil, either stored at room temperature or in the refrigerator. This may be related to the content of essential oils of sweet orange peel containing flavonoids and antibacterials that are capable of maintaining liquid semen quality of Boer Goat.In addition, gentamicin contains antibacterials capable of suppressing the growth of bacteria which can damage and durabilitythe spermatozoa.Keywords: Boer Goat,Gentamicin, Liquid semen, Sweet orange

Composting of organic waste into compost can be accelerated by using EM4. The nutrients can be obtained from carbohydrate sources, sugar cane, sugar, and brown sugar. This study aimed to determine the quality of Indian almond leaves compost with the addition of carbohydrate sources, sugar cane water, sugar, and brown sugar. The study employed a qualitative descriptive to describe the quality of the compost which refers to the National Compost Standard (SNI: 19-7030-2004). The results showed that the quality of the compost with the addition of the aforementioned carbohydrates sources has a C/N ratio value that exceeds the National Compost Standard (SNI: 19-7030-2004). Meanwhile, other characteristics such as temperature, pH, humidity, texture, color, and smell had met the requirements of the National Compost Standard (SNI: 19-7030-2004). The most effective source of carbohydrates for producing quality compost was brown sugar.
