“…Valorisation of unavoidable waste from food manufacturing processes through eco-innovative integrated biorefinery systems is imperative to align with or exceed the United Nations Sustainable Goals [1,7,10,11]. We advance the present state of knowledge [19][20][21][22] in three intersecting arenas of food in a synergistic manner by analysing environmental footprints of food choices using the holistic whole system life cycle assessment, illustrating protein isolation pathways from plant-based sources and design-conceptualising sustainable biorefinery systems to valorise unavoidable food waste for a circular economy.…”

Planet Earth is under severe stress from several inter-linked factors mainly associated with rising global population, linear resource consumption, security of resources, unsurmountable waste generation, and social inequality, which unabated will lead to an unsustainable 21st Century. The traditional way products are designed promotes a linear economy that discards recoverable resources and creates negative environmental and social impacts. Here, we suggest multi-disciplinary approaches encompassing chemistry, process engineering and sustainability science, and sustainable solutions in “game changer” challenges in three intersecting arenas of food: Sustainable diet, valorisation of unavoidable food supply chain wastes, and circularity of food value chain systems aligning with the United Nations’ seventeen Sustainable Development Goals. In the arena of sustainable diet, comprehensive life cycle assessment using the global life cycle inventory datasets and recommended daily servings is conducted to rank food choices, covering all food groups from fresh fruits/vegetables, lentils/pulses and grains to livestock, with regard to health and the environment, to emphasise the essence of plant-based diet, especially plant-based sources of protein, for holistic systemic sustainability and stability of the earth system. In the arena of unavoidable food supply chain wastes, economically feasible and synergistically (energy and material) integrated innovative biorefinery systems are suggested to transform unavoidable food waste into functional and platform chemical productions alongside energy vectors: Fuel or combined heat and power generation. In the arena of circularity of food value chain systems, novel materials and methods for plant-based protein functionalisation for food/nutraceutical applications are investigated using regenerative bio-surfactants from unavoidable food waste. This circular economy or industrial symbiosis example thus combines the other two arenas, i.e., plant-based protein sourcing and unavoidable food waste valorisation. The multi-disciplinary analysis here will eventually impact on policies for dietary change, but also contribute knowledge needed by industry and policy makers and raise awareness amongst the population at large for making a better approach to the circular economy of food.

“…Therefore, new economic strategies should be evaluated to reduce the discards and postharvest losses and increase the aggregate value of this food crop (Petsakos et al 2019). In these terms, flour production with blends formulated with different groups of compounds and using residues for substitution in food products such as cookies, pasta, and bread represent a challenge for the food industry (Morone et al 2019).…”

“…The use of blends from banana pulp and peels for cake production is an innovative development that can align with the use of the peels discarded for the improvement of quality in food production (Morone et al 2019).The use of banana peels can increase the economic development for a value-add in this food chain. Additionally is known that banana peel have antioxidant properties, principally due de secondary metabolites such as phenolic compounds present in the peel (Vu et al 2018;Kamel et al 2017).…”

The food product industry is increasingly looking for foods with nutritional properties that can provide health benefits. Additionally, a challenge for the food industry is the use of all raw materials. For these reasons, banana peel that is a raw material from Banana (Musa spp.) fruit emerges as potential for new food product development. Here, we developed powder blends using a lyophilization process for the preparation of flour to potential use in cookies, bread, and pasta products. Three formulations were designed; the main difference in the formulations was the use of banana peel concentration. Our results showed that blends produced with banana peel presented physical-chemical properties considered suitable for use in food industry. Moreover, the evaluated morphological parameters reveal the properties of the powders. The blends formulated with banana peel have more antioxidant properties, showing that the banana peel may be an attractive option to generate powders with high antioxidant properties.

“…One-third of the world’s food production is discarded every year [1,2]. This implies different types of environmental, social, and economic challenges, specifically in developing countries where the proportions of food waste (FW) in municipal waste are high [3,4,5,6].…”

Composting is considered an option for the disposal of organic waste; however, the development of portable and low-cost systems for its monitoring is of high interest. Therefore, in this study, respirometric microsystems were designed and tested including two integrated oxygen sensors for the measurement of compost samples under static and dynamic conditions with high portability and ease of use. The cost of each sensor was calculated as 2 USD, while the cost of the whole respirometric microsystem was calculated as 6 USD. The electronic system for real-time monitoring was also designed and implemented. The designed systems were tested for over 6 weeks for the determination of compost quality using real samples. The respirometric microsystem was compared to a commercial respirometry system and a standard laboratory test using hierarchical analysis which included costs, portability accuracy, analysis time, and integration of new technologies. The analysis showed a global score of 6.87 for the respirometric microsystem compared to 6.70 for the standard laboratory test and 3.26 for the commercial system.
