Organic waste is derived from production processes, the amount of waste generated from two factories participating in this work reaches approximately 2000t / year, directly impacting the environment, making areas conducive to the development of insects and pests attracted by the discarded residual food. The cost used in the correct disposal of this waste, directing it to the local landfill is approximately R $ 150,000.00 / year. Considering the great nutritional value present in biomass, this work aimed to reuse these residues to produce a dog food. For this, a methodology was created to treat these biomasses, transforming them into co-products for commercialization. With this, a formulation was developed incorporating the by-products of olives, papayas and oranges, plus other essential ingredients for dog food, complying with the current legislation, resulting in a product with high added value. The developed feed used 38% of the residual biomass in its composition, and compromised, through the simulated study, all the material generated by the industries, being able to reduce a large part of the disposal expenses to the sanitary landfill. The generation of revenue from the sale of biomasses has subtracted the expenses with landfill disposal, making the process economically viable in addition to proposing a sustainable solution to the manufacturing process.

Currently, agricultural production generates large amounts of organic waste, both from the maintenance of farms and crops, and from the industrialization of the product. Generally, these wastes are accumulated in landfills or burned, sometimes causing environmental problems. However, many scientific studies suggest that these residues are rich in bioactive compounds, so these matrices could be revalued for their use in food, cosmetic, or pharmaceutical industries. In this way, the circular and sustainable economy is favored, while obtaining products with high added value. In this case, this approach is applied to the residues generated from kiwi production, since numerous studies have shown the high content of kiwi in bioactive compounds of interest, such as phenolic compounds, vitamins, and carotenoids. These compounds have been reported for their antioxidant, anti-inflammatory, and antimicrobial activities, among other beneficial properties for health such as its use as prebiotic. Therefore, this article reviews the potential of residues derived from industrial processing and agricultural maintenance of kiwi as promising matrices for the development of new nutraceutical, cosmetic, or pharmacological products, obtaining, at the same time, economic returns and a reduction of the environmental impact of this industry, attaching it to the perspective of the circular economy.

The search for waste minimization and the valorization of by-products are key practices for good management and improved sustainability in the food industry. The production of almonds generates a large amount of waste, most of which is not used. Until now, almonds have been used for their high nutritional value as food, especially almond meat. The other remaining parts (skin, shell, hulls, etc.) are still little explored, even though they have been used as fuel by burning or as livestock feed. However, interest in these by-products has been increasing as they possess beneficial properties (caused mainly by polyphenols and unsaturated fatty acids) and can be used as new ingredients for the food, cosmetic, and pharmaceutical industries. Therefore, it is important to explore almond’s valorization of by-products for the development of new added-value products that would contribute to the reduction of environmental impact and an improvement in the sustainability and competitiveness of the almond industry.

Unconventional Feed

A modern animal husbandry needs balanced feeding with rational use of feed and the maximum involvement of unconventional feed. At the same time, issues of increasing the nutritional value of feeds, improving quality, reducing the share of cereals remain urgent, since they occupy a significant part in the composition of the diet and cost structure. The application of modern feed processing technologies increases the efficiency of their use, increases the performance of animal husbandry, as evidenced by numerous experiments. The organization of feed production based on own feed resources significantly reduces the cost of production. The application of a number of technologies has been discussed and justified, which allows obtaining feed with high zootechnical and consumer characteristics, as well as with high rates of nutrition, digestibility and biological value with a significant reduction in the cost of feeding.

As an educational city, Jatinangor has a fairly large population density. In turn, it generates restaurant organic waste in large quantities. Excessive production of organic waste will be a problem if it is not accompanied by good management and utilization. One of the efforts in utilizing restaurant waste is to turn the waste as fish feed. This study aims to calculate the production of restaurant waste and analyze the cost of production of fish feed using restaurant waste flour. The production of restaurant waste was calculated using purposive random sampling, while the cost of feed production was determined by using variable costing method. Questionnaires and research primary data were used to collect data. The results obtained from this study were as such: production of restaurant waste in the Jatinangor area is 261.7 Kg/day, the cost of production for fish feed with the basic ingredients of restaurant waste flour is 70,013,127 IDR with a production capacity of 6,913.1 kg of fish feed per year, so that the cost of feed per kilogram is 10,127.60 IDR, and the selling price of feed is 12,200 IDR/kilogram with a profit of 20%. Thus, it can be seen that independent feed production using restaurant waste can be a solution in the utilization of waste and can also be used as a source of income for the surrounding community.

Purpose The purpose of this paper was to promote the use of residual moringa seed powder (RMSP) for the enhancement of cereal-based products. RMSP is usually discarded after seed-oil extraction. This work also promotes zero-waste and rheological approaches. Design/methodology/approach In search of novel and sustainable food products with high nutritional value, cold-pressed Moringa oleifera Lam. seeds residue (RMSP) was used for incorporation in muffin formulations. Wheat flour was partially substituted (0%, 1%, 3%, 5%, 7% and 9%) by RMSP. Sodium (Na), calcium (Ca) and iron (Fe) contents were quantified through atomic absorption spectrometry; protein, through the Kjeldahl method followed by AACC Method 46–13.01; and, fat content, by a modified version of AACC Method 30–25.01a. Analysis of variance (ANOVA) and Tukey tests were performed to determine significant differences between formulations at 95% reliability using Minitab® software. Furthermore, simple viscosity studies of the dough mixture were carried in a Brookfield DV-III Ultra Rheometer; Matlab® curve-fitting tool was used for obtaining the best non-Newtonian equation that modeled experimental data. Subsequently, computational fluid dynamics (CFD) simulations of non-Newtonian fluids along a segmented pipe were carried out in Comsol Multiphysics® software to depict the importance of modeling non-Newtoning fluids for downstream processes. Findings RMSP significantly (p < 0.0001) increased protein and Fe content for the 7% and 9% formulations; it dramatically changed Na and Ca content in all formulations, while fat remained constant. Social implications The development of this type of product is an opportunity for communities that grow and harvest moringa as well as for food industries which can take advantage of moringa by-products for several subsequent processing. Originality/value For the first time, it was found that dough formulations with RMSP presented a pseudo-plastic and thixotropic behavior. In addition, the use of lignocellulosic by-products such as RMSP incorporates an added value to food products. In this case, it was demonstrated that moringa seed residue enhanced nutritional value to muffins and provided coagulant/flocculant action, which is essential during dough preparation.

Nowadays, the potato is one of the most cultivated and consumed food crops in the world and, in recent years, its production has experienced a sharp increase. Its industrial processing generates several by-products that are wasted and cause economic and environmental problems. Among them, potato peel stands out, representing up to 10% of the total potato residues obtained in the processing. On the other hand, these wastes, in addition to presenting antioxidant compounds, are rich in interesting chemical compounds of great value in a biorefinery model. This review summarizes the main compounds present in potato skins as well as the most used and innovative extraction methods employed for their isolation, with special emphasis on the fractions with biological activities. In addition, a sustainable biorefinery proposal focused on obtaining high added-value products with potential applications in the pharmaceutical, food, nutraceutical, or cosmetic industries is included.

Processing of fish in aquaculture generates considerable amounts of by-products that remain underused and/or unexploited. We evaluated the nutritive content of fish by-products (head, gills, intestines, trimmings, bones, and skin) from meagre and gilthead sea bream fish species reared in Greece in order to estimate their nutritional value for future development of high added-value products. The proximate composition of the fish samples (total protein, total lipid, ash, moisture, and macro-element content) was determined using the Association of Official Analytical Chemists (AOAC) and International Organization for Standardization (ISO) official methods. The content of fatty acids was determined using capillary gas chromatography, and the protein profile was estimated employing scientific orbitrap mass spectrophotometer methodology. The nutrient composition of fish by-products presented fluctuations among the different by-products. Skin was the most significant protein source, trimmings and bones were high in calcium, and the head, intestines, and bones were a good source of lipids. The most abundant lipid acids found in by-products were oleic, palmitic, linoleic, and eicosenoic acids, whereas the most abundant proteins were adenosine triphosphate (ATP) synthase subunit epsilon, mitochondrial nicotinamide adenine dinucleotide (NADH) dehydrogenase, and mitochondrial cytochrome b-c1 complex subunit 8. These data suggest that by-products constitute valuable sources of nutrients and could therefore be exploited in accordance with the principles of a circular economy.

The use of anaerobic digesters to convert residual biomass for energy use and nutrient recovery has been increasingly indicated by the operational simplicity and added value of the treatment by-products. However, the levels of solids present in the influents to be treated directly influence the operation and management of the system. Thus, the objective of the study was to evaluate the performance of covered lagoon digesters in terms of the solids loading in the swine wastewater treatment system. The study was performed in a farm located in Zona da Mata Mineira. The monitoring took place from September 2018 to August 2019. The influent flow of waste was estimated based on the analysis of monthly water consumption on the farm. The collection and sampling took place weekly, the influents and effuents were analyzed in terms of the solids loading of total solids (TS) and volatiles solids (VS). The mean total flow distributed to the two digesters was 102.3 m³.d-1, with a mean hydraulic retention time (HRT) of 24.5 days. The results ranged from 1.14 to 2.83% for TS at the start of treatment. In most of the monitored months, anaerobic digesters were being fed with organic overload in terms of VS, which consequently affected the efficiency of the system, which were 33.6% for TS and 39.5% for VS.

Peru is one of the main areas where there are large cocoa crops with special relevance to the economy of this country. In fact, cocoa is a major, economically important, international crop which has been linked to several benefits, such as anti-allergenic, anti-atherogenic, anti-inflammatory, anti-microbial, anti-oxidant, anti-thrombotic, cardioprotective and vasodilatory properties, relating to its bioactive compound content. However, in cocoa industrial processing, several residues or wastes, which are commonly discarded generating a negative impact on the environment, are produced in large amounts. Some of the cocoa by-products, which go underutilized, could be a good source of bioactive compounds with high utility for the development of innovative products in nutraceutical, medical or pharmaceutical industries. For this reason, the aim of this study is to qualitatively determine the phytochemical composition of husk and bean extracts from different cocoa-growing areas and processes from Peru by high performance liquid chromatography coupled to mass spectrometry. Furthermore, we aim to evaluate their phenolic and flavan-3-ol contents and antioxidant capacities for the purpose of highlighting the potential of cocoa by-products from these cultivars as functional ingredients. In total, 49 chemical compounds were detected in the analyzed extracts. Comparing both husks and beans, bean extracts were characterized by high content in flavonoids whereas husk extracts had a higher content of phenolic acids. The presence of these compounds together with the bioactivity results suggest that these matrices may be further studied for their revaluation in the development of high added-value products in nutraceutical, medical, and pharmaceutical industries.

The industrial processing of tomato leads to substantial amounts of residues, typically known as tomato pomace or by-products, which can represent as much as 10% by weight of fresh tomatoes. At present, these residues are either used as feedstock for animals or, in the worst case, disposed of in landfills. This represents a significant waste because tomato pomace contains high-value compounds like lycopene, a powerful antioxidant, cutin, which can be used as a starting material for biopolymers, and pectin, a gelling agent. This article presents an overview of technologies that valorize tomato by-products by recovering added-value compounds as well as generating fuel for energy production. These technologies include operations for extraction, separation, and exploitation of lycopene, cutin and pectin, as well as the processes for conversion of the solid residues to fuels. Data collected from the review has been used to develop a biorefinery scheme with the related mass flow balance, for a scenario involving the tomato supply chain of Regione Campania in Italy, using tomato by-products as feedstock.
