“…This observation corresponds with the results of comprehensive studies on the food industry, which state that a considerable amount of energy is required for evaporation and freezing processes [10]. Currently, most of this energy is generated using fossil fuels and the decarbonisation of these processes is key for a green transition of the industry [11].…”

This study investigates the integrated heat pump system of a green-field dairy located in Bergen, Norway. The purpose of the study is to determine the energy consumption and system performance. The dairy features a novel and innovative solution of a fully integrated energy system, employing high temperature heat pumps such as the hybrid absorption-compression heat pump (HACHP) with natural refrigerants to provide all temperature levels of heating and cooling demands. To evaluate the performance an energy analysis has been performed based on available process data for a comparatively energy-intensive week in February. The results have shown that the integrated system is able to meet the occurring demands. Furthermore, the specific energy consumption with 0.22 kWh l − 1 product can outperform the annual average value of the replaced dairy even under difficult conditions. However, it is expected that the specific energy consumption will be further reduced on an annual basis. Through measures such as the extensive use of waste heat recovery accounting for 32.7% of the energy used, energy consumption was reduced by 37.9% and greenhouse gas (GHG) emissions by up to 91.7% compared to conventional dairy systems. Simultaneous, the process achieves a waste heat recovery rate of over 95%. Furthermore, demand peaks were compensated and a system coefficient of performance (COP) of 4.1 was achieved along with the identification of existing potential for further improvements.

“…Solar energy is suitable and effective for industrial processes and AcoD, as discussed in section VI, given process characteristics and biowaste produced in the FVPI is also a good technological option [22], [91]. Only few authors mention the integration of these technologies [92], [93] therefore discussing this proposed approach within the academic and industry community could open the way to discussion on its possible advantages and constraints.…”

Integrated Renewable Energy Systems in Fruit and Vegetable Processing Industries: A Systematic Review

The exponential population growth will put great pressure on natural resources, agriculture, energy systems and waste production. New business models and innovative technological approaches are necessary to tackle these challenges and achieve the energy transition targets set by the European Commission. Renewable energy technologies and processes such as solar photovoltaic, solar thermal and anaerobic co-digestion have become a subject of interest and research as a solution that could be fully implemented in industries and solve several environmental and economic problems. This paper discusses the possibility of integrating and complement these technologies to maximize renewable energy production and circularity. The review was performed with a funnel approach aiming to analyze broad to specific subjects. Beginning with a literature review on the various definitions of circular economy, bioeconomy, and circular bioeconomy, ultimately proposing a single definition according to an industrial and academic scope combination, followed by a systematization and assessment of data and literature regarding energy systems present state and projections. The next phase was to assess data and literature of the fruit and vegetable processing industry from an energy consumption and biowaste production perspective to consequently discussing technologies that could help manage problems identified throughout this review. This paper culminates in propounding an Integrated Renewable Energy System conceptual model that promotes energy and waste circularity, envisioning how industries could be designed or redesigned in the future, coupled with a circular bioeconomy business model.

“…The industrial sector is considered as an appropriate case for implementing DR programs, because of the large size of individual industrial buildings and their flexibility in many manufacturing processes. It means that electricity consumption in industrial buildings can be shifted from day to night if needed, however, it is not easy in residential and office buildings [8]. Load shifting in industrial buildings is more useful since it does not have an effect on the total amount of energy demand, but it affects load profile shape by moving part of energy consumption from one period to another period [9,10].…”

In this paper, the proposed methodology minimizes the electricity cost of a laundry room by means of load shifting. The laundry room is equipped with washing machines, dryers, and irons. Additionally, the optimization model handles demand response signals, respecting user preferences while providing the required demand reduction. The sequence of devices operation is also modeled, ensuring correct operation cycles of different types of devices which are not allowed to overlap or have sequence rules. The implemented demand response program specifies a power consumption limit in each period and offers discounts for energy prices as incentives. In addition, users can define the required number of operations for each device in specific periods, and the preferences regarding the operation of consecutive days. In the case study, results have been obtained regarding six scenarios that have been defined to survey about effects of different energy tariffs, power limitations, and incentives, in a laundry room equipped with three washing machines, two dryers, and one iron. A sensitivity analysis of the power consumption limit is presented. The results show that the proposed methodology is able to accommodate the implemented scenario, respecting user preferences and demand response program, minimizing energy costs. The final electricity price has been calculated for all scenarios to discuss the more effective schedule in each scenario.
