“…HPP contributes to environmental sustainability by providing nutritious, safe, and healthy food with an acceptable shelf life in developed countries [186]. HPP has been proven more effective than MAP (modified atmosphere packaging) from an environmental and an economic perspective [187]. However, due to recent food loss and food waste, environmental sustainability may be threatened [187].…”

Sustainable food supply has gained considerable consumer concern due to the high percentage of spoilage microorganisms. Food industries need to expand advanced technologies that can maintain the nutritive content of foods, enhance the bio-availability of bioactive compounds, provide environmental and economic sustainability, and fulfill consumers’ requirements of sensory characteristics. Heat treatment negatively affects food samples’ nutritional and sensory properties as bioactives are sensitive to high-temperature processing. The need arises for non-thermal processes to reduce food losses, and sustainable developments in preservation, nutritional security, and food safety are crucial parameters for the upcoming era. Non-thermal processes have been successfully approved because they increase food quality, reduce water utilization, decrease emissions, improve energy efficiency, assure clean labeling, and utilize by-products from waste food. These processes include pulsed electric field (PEF), sonication, high-pressure processing (HPP), cold plasma, and pulsed light. This review describes the use of HPP in various processes for sustainable food processing. The influence of this technique on microbial, physicochemical, and nutritional properties of foods for sustainable food supply is discussed. This approach also emphasizes the limitations of this emerging technique. HPP has been successfully analyzed to meet the global requirements. A limited global food source must have a balanced approach to the raw content, water, energy, and nutrient content. HPP showed positive results in reducing microbial spoilage and, at the same time, retains the nutritional value. HPP technology meets the essential requirements for sustainable and clean labeled food production. It requires limited resources to produce nutritionally suitable foods for consumers’ health.

“…Furthermore, bio-based/peat-free soil improvers can contain secondary raw material derived from various waste streams (Chojnacka et al, 2020;EC, 2017;Taparia et al, 2021). Motivation to develop peat-free soilimproving amendments is based on a sustainable bioeconomy approach, also grounded in the ideas of the European Green Deal, such as moving to 'zero waste' production, resource efficiency, ensuring the quality of the environment (Awasthi et al, 2021;EC, 2019). Advantages prevail over disadvantages, especially in the long-term (Figure 1).…”

Increasing global population and urbanization demands enhanced food and feed crop production, but due to several reasons, the areas of fertile agricultural lands are reducing worldwide. The market of growing substrates, soil amendments, and improvers still is based on peat extraction and processing. Due to peat's fossil origin, it can be considered environmentally unfriendly and unsustainable. Seeking peat-substituting materials is of crucial importance on a global scale and may become a vitally significant assignment for future generations. The necessity for peat-free soil amendments is also directed by the targets of circular economy and environmental sustainability goals, leading to reducing or abandoning the use of fossil resources and paying attention to waste utilization as secondary raw material. This paper aims to discuss general features of peat-free soil amendments as well as provide efforts into the use of secondary raw materials such as biomass ashes for the elaboration of peat-free soil-improving products. As a case example, may serve a description of the peat-free product made by rotary drum granulation from biomass fly ashes (energy production waste) and local freshwater sediments in a mass ratio mixture of 67:100, optimally applicable for soil improvement at a rate of 50 g L -1 . Besides, regional opportunities in Indonesia and Latvia are referred. It was concluded that peat-free soil amendment elaboration can be better implemented on a regional scale after assessing agricultural needs, soil specifics, and available raw material variety applicable as ingredients in soil-improving products.

This study is a starting point for the development of an efficient method for rare earths (REs) and transition metals (TMs) recovery from waste electrical and electronic equipment (WEEE) via a hydrometallurgical process. The capture and release capability of mineral clays (STx) and activated carbons (AC), pristine and modified (STx-L6 and AC-L6) with a linear penta-ethylene-hexamine (L6), towards solutions representative of the process, are assessed in the lab-scale. The solids were contacted with synthetic mono- and bi-ionic solutions containing Ni(II) and La(III) in a liquid/solid adsorption process. Contacting experiments were carried out at room temperature for 90 min by fixing a La concentration at 19 mM and varying the Ni one in the range of 19–100 mM. The four solids were able to capture Ni(II) and La(III), both in single- and bi-ionic solutions; however, the presence of the polyamine always results in a large improvement in the capture capability of the pristine sorbents. For all the four solids, capture behaviour is ascribable to an adsorption or ion-sorbent interaction process, because no formation of aquo- and hydroxy-Ni or La can be formed. The polyamine, able to capture Ni ions via coordination, allowed to differentiate ion capture behaviour, thus bypassing the direct competition between Ni and La ions for the capture sites found in the pristine solids. Release values in the 30–100% range were found upon one-step treatment with concentrated HNO3 solution. However, also, in this case, different metals recovery was found depending on both the sorbent and the ions, suggesting a possible selective recovery.
