Waste orange peel represents a heavy burden for the orange juice industry, estimated in several million tons per year worldwide; nevertheless, this by-product is endowed with valuable bioactive compounds, such as pectin, polyphenols, and terpenes. The potential value of the waste orange peel has stimulated the search for extraction processes, alternative or complementary to landfilling or to the integral energy conversion. This study introduces controlled hydrodynamic cavitation as a new route to the integral valorization of this by-product, based on simple equipment, speed, effectiveness and efficiency, scalability, and compliance with green extraction principles. Waste orange peel, in batches of several kg, was processed in more than 100 L of water, without any other raw materials, in a device comprising a Venturi-shaped cavitation reactor. The extractions of pectin (with a remarkably low degree of esterification), polyphenols (flavanones and hydroxycinnamic acid derivatives), and terpenes (mainly d-limonene) were effective and efficient (high yields within a few min of process time). The biomethane generation potential of the process residues was determined. The achieved results proved the viability of the proposed route to the integral valorization of waste orange peel, though wide margins exist for further improvements.

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.

A brief technical and economic insight into producing the water-soluble yellow colorant limocitrol 3-O-6”-[3-hydroxyl-3-methylglutaryl)])-β-D-glucopyranoside from waste lemon peel via simple solid-liquid extraction in aqueous ethanol or via hydrodynamic cavitation of waste lemon peel in water, shows that the biocolorant can be obtained at affordable cost. Coupled to the simplicity and sustainability of the extraction processes suggested, the high chemical and physical stability of this polymethoxylated flavanol and the health benefits of citrus flavonoids, support industrialization of this new bioeconomy production.

Improving the food system sustainability and security is becoming an urgent global challenge. In this regard, one of the most effective routes is the shift of the human diet toward healthier and more sustainable consumption, involving in particular the prevalence of plant-based raw food materials. Controlled hydrodynamic cavitation (HC) technologies could help considerably in this transition. HC techniques are gaining increased scientific interest, and are quickly spreading across a wide range of technical fields, recently showing surprising performances with biological raw materials related to the food, agricultural and forestry sectors and resources. HC processes enjoy recognized advantages in the acceleration of the processing steps of plant-based food, the extraction of valuable bioactive compounds, the reduction and the valorization of waste streams, as well as the superior efficiency in resource use, energy consumption, process yield, and exergy balance than competing processes. Thus, HC is very promising candidate to help addressing the water-energy-food nexus, and, ultimately, sustainability. Findings obtained from direct experimental trials and recent literature concerning the applications of HC to food processing, provide a strong basis for novel investigation aimed at standardization, starting from the identification of the most suitable devices and the optimal processing parameters, eventually oriented to further spreading of HC applications.

The food industry is one of the industries that is growing very rapidly throughout the world, including in Indonesia. Various types of food and beverages with an attractive appearance continue to be produced to increase the aesthetic value and attractiveness of consumers. Food and beverage production processes include the selection of raw materials, food and beverage processing, food and beverage quality testing, packaging to the food and beverage distribution process. Every process that takes place must be controlled so that the final product produced is safe and suitable for consumption by consumers. Zalacca production in Karangasem Regency is very good to be developed into the useful food industry. The development of the zalacca-based food industry can increase added value for the people and zalacca commodities. The results of the study using the Process Hierarchy Analysis methodology show that Chips, Syrups, and Extracts occupy high yields to be developed.

Methylene Blue Adsorption

In order to reduce power plant nitric oxide emission with gaining economical adsorbent, activated carbon was prepared from the raw materials of orange peel under different operating conditions in this paper. The methylene blue adsorption value of different activated carbon has also been tested, and the effects on the methylene blue adsorption performance of different dipping concentration, activation time and carbonization temperature were studied. The finding is that the dipping concentration has the most important impact on methylene blue adsorption value. The highest methylene blue adsorption value of orange peel activated carbon has shown as 277.746mg/g under the following conditions: phosphoric acid concentration was 40%, activation time was 12 hours and carbonization temperature was 500°C. It is a economically feasible absorbent material through a great deal of experiments and analysis.

Heavy Burden

High-efficient recycling of solid waste from the semiconductor or textile dyeing industry has been a challenge since these industrial waste not only brings a heavy burden to enterprises but also seriously affects our ecological environment. Here, a feasible method is proposed to recycle this solid waste by transferring it into high value-added ceramsites. They were prepared by using the third grade sand of cutting silicon (TGSCS) and textile dyeing sludge (TDS) as raw materials and composed mainly of SiO2–Al2O3. Through systematic analysis of the experimental results, it was concluded that the optimized ratios of the TGSCS and the TDS should range from 1:1.5 to 1:3, while the sintering temperature should be around 1150[Formula: see text]C. These lightweight ceramsites can have excellent properties of the cylinder compressive strength of 4.65 MPa and bulk density of 477 kg/m3. The potential expansion mechanism was thought to be related to both TGSCS and TDS as they reacted with Fe2O3 impurity to form CO2/CO gases. This work is to prepare lightweight ceramsites and to recycle solid waste.
