“…A wide range of techniques and tools have been created to offer direction in the circular business model innovation process and assist companies in overcoming the difficulties encountered when building and innovating business models towards circularity. Business model innovation is best defined as an iterative process with various stages (such as conception, implementation, and assessment) [38] and varying degrees of detail (such as modifications at the conceptual level to changes in operational processes) [39]. The new sustainable models that are developed must go beyond sustainability and achieve sustainable income, based on an adjustment of the traditional growth framework, which can be used to restore natural resources while also being economically viable [40,41].…”

Inadequate production practices are widely used in aquaculture management, causing excessive water and energy usage, as well as ecological damage. New approaches to sustainable aquaculture attempt to increase production efficiency, while reducing the quantities generated of wastewater and sludge. The sustainable operating techniques are often ineffective, expensive, and difficult to implement. The present article proposes a zero-waste production system, designed for growing fish and vegetables, using a new circular operational concept that creates synergies between fish farming and horticulture. In order to optimize the operational flows with resources, products, and wastes in an integrated zero-waste food production cluster, a business model was designed associating three ecological production practices: a closed fishing pond, a technology for growing vegetables in straw bales, and a composting system. The design had the role to assist the transition toward multiple circular material flows, where the waste can be fully reintegrated into the production processes. A comparative evaluation was conducted in three alternative growing environments, namely, a soilless culture established in straw bales, a culture grown in soil that had received compost fertilizer, and the conventional farming technique. When compared to conventional methods, experiments showed a significant increase in the cluster’s cumulative productivity, resulting in a 12% improvement in energy efficiency, 18% increase in food production, and 25% decrease in operating expenses.

“…Since there are only a few crops that can survive in the context of increasing desertification, this poses a severe economic and environmental issue. It is important to search for methods and techniques that optimize efficiency and productivity in the use of water in a semi-arid region where water resources are severely constrained [16], both in terms of availability and cost.…”

Productivity in viticultural practices is highly dependent on seasonal availability of rainfall and the efficiency of soil and water conservation strategies. Sustainable water consumption has been regarded as a business, social, and environmental responsibility, since resource availability becomes more challenging. The present research evaluates a new agricultural equipment design, employed in furrow compartmentalization works, with the aim of improving the efficiency of rainwater storage in the soil, reducing the runoff and the erosion on sloping soils. The newly developed equipment operates on the basis of a rigid memory and employs the cam-tappet mechanism, known for its high customization potential. The system functionality has been improved by integrating enhanced hoe shapes, adapted for the demanding working conditions encountered in vineyards. The evaluated performance indicators showed an increased up to 7% of the water storage effectiveness, while the micro-basins construction performance improved by 10%. The furrow diking phase is integrated into the weeding works, and recorded low additional fuel consumption of only 3–5%, being appreciated by farmers due to its constructive simplicity. As a result, the equipment has shown a significant application potential to increase deep water storage in vineyards and reduce the negative impacts of climate change on agriculture.

“…Cleaning represents the set of operations performed to remove impurities from the mass of products while sorting aims to separate the seed categories of size, shape, and color. That is why, in order to establish a technology for separating impurities, the physicalmechanical properties of both the basic product and the impurities were analyzed [48][49][50]. The most significant quality requirements regarding the purity and uniformity of the grains are met in the field of processing and obtaining seeds intended for sowing [51][52][53][54].…”

The current study focuses on analyzing the impact of integrating an optical sorter in a seed-separation technological flow, in terms of increasing the quality of the maize seeds appropriate for sowing. The study showed that there are situations when the use of optical separation may result in a number of difficulties in removing a variable rate of good seeds from the raw mass, which can bring economic disadvantages. The identified issue encouraged the development of several flow assessment approaches in order to determine the problem’s essence and to develop the best strategy for action. The key finding was that the evaluated optical sorting equipment cannot eliminate impurities without also removing good seeds, resulting in every 1% increase in impurity level and a rate of 0.70% of the good seeds lost. Therefore, farmers must carefully consider the scenarios where integrating optical sorting into their technological flow is a suitable option, considering the input material quality, the selling price of the product, and the risk of missing an important quantity of high-quality seeds. The working method described may be of significant importance to other farmers who intend to choose the components of grain-cleaning processes effectively.
