“…Due to the significant amount of apple pomace produced worldwide (~4 million tons year −1 ), strategies other than energy production are being explored and evaluated regarding the environmental impact generated. 76 For example, technological alternatives for obtaining natural active compounds, 77 the production of acrylic acid, 78 n-butanol, acetone and ethanol, 79 biosuccinic acid, 80 pectin, and fermentable sugars, 67 among others, can be used as food ingredients. 81 Cerutti et al 40 selected the best parameters for an LCA application in fruit-production systems and showed great potential for the absorption and net storage of CO 2 , but specific models for orchard systems were omitted.…”

The food industry generates large volumes of organic by‐products, which require proper environmentally friendly disposal. In the case of the apple‐processing industry, apple pomace constitutes 25–30% of the original apple weight. The conventional treatment of food industry by‐products involves composting, which releases greenhouse gases and contributes to climate change. This study presents an environmental assessment of apple pomace management technologies for industrial juice processing. The life cycle analysis (LCA) methodology was applied as a tool for evaluating the technological routes of composting (method conventionally used) and anaerobic digestion (AD) (an innovative technological route). The main change proposed to the current process would be the implementation of anaerobic reactors in the apple industry, avoiding the transport of apple pomace to the composting unit and producing bioenergy from the burning of methane‐rich biogas. The results showed a reduction in the environmental impacts in the system composed of AD of apple pomace. In the categories related to eutrophication and acidification, a reduction of approximately 50% was obtained when comparing AD with composting. The global warming potential and greenhouse gas emissions showed a significant reduction with the adoption of AD, due to the conversion of biogas into energy and its use by the industry. In conclusion, the implementation of AD technology for the management of apple pomace can be a promising alternative to recover bioenergy and decrease the environmental impacts caused by the apple‐juice processing industry. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

Billions of tons of agro-industrial residues are produced worldwide. This is associated with the risk of pollution as well as management and economic problems. Simultaneously, non-edible portions of many crops are rich in bioactive compounds with valuable properties. For this reason, developing various methods for utilizing agro-industrial residues as a source of high-value by-products is very important. The main objective of the paper is a review of the newest studies on biologically active compounds included in non-edible parts of crops with the highest amount of waste generated annually in the world. The review also provides the newest data on the chemical and biological properties, as well as the potential application of phytochemicals from such waste. The review shows that, in 2020, there were above 6 billion tonnes of residues only from the most popular crops. The greatest amount is generated during sugar, oil, and flour production. All described residues contain valuable phytochemicals that exhibit antioxidant, antimicrobial and very often anti-cancer activity. Many studies show interesting applications, mainly in pharmaceuticals and food production, but also in agriculture and wastewater remediation, as well as metal and steel industries.

“…In the last 25 years, apple pomace has been used to produce several products, such as enzymes, polygalacturonases or hydrolytic depolymerases, involved in the degradation of pectic substances. It has also been applied in food and textile processing [ 73 , 74 ]. Apple pomace has been used as a substrate for bioethanol production [ 75 ] and biopolymer synthesis, such as fungal chitosan [ 72 ].…”

Agri-Food Waste from Apple, Pear, and Sugar Beet as a Source of Protective Bioactive Molecules for Endothelial Dysfunction and Its Major Complications

Endothelial damage is recognized as the initial step that precedes several cardiovascular diseases (CVD), such as atherosclerosis, hypertension, and coronary artery disease. It has been demonstrated that the best treatment for CVD is prevention, and, in the frame of a healthy lifestyle, the consumption of vegetables, rich in bioactive molecules, appears effective at reducing the risk of CVD. In this context, the large amount of agri-food industry waste, considered a global problem due to its environmental and economic impact, represents an unexplored source of bioactive compounds. This review provides a summary regarding the possible exploitation of waste or by-products derived by the processing of three traditional Italian crops—apple, pear, and sugar beet—as a source of bioactive molecules to protect endothelial function. Particular attention has been given to the bioactive chemical profile of these pomaces and their efficacy in various pathological conditions related to endothelial dysfunction. The waste matrices of apple, pear, and sugar beet crops can represent promising starting material for producing “upcycled” products with functional applications, such as the prevention of endothelial dysfunction linked to cardiovascular diseases.
