Connectivity is key: holistic sustainability assessment and reporting from the perspective of food manufacturers

Küchler, R. ., & Herzig, C. . (2021). Connectivity is key: holistic sustainability assessment and reporting from the perspective of food manufacturers. British Food Journal. http://doi.org/10.1108/BFJ-03-2021-0317

Abstract

As members of the food supply chain, food manufacturers acquire power and hold responsibility for the sustainable transformation of our food systems. Sustainability assessment and reporting frameworks function as instruments to shape sustainable transformation processes. Their suitability for food manufacturing companies and their connectivity with the up- and downstream food supply chain is investigated here. The first section of the study explores the need for holistic, company-based sustainability frameworks in the food manufacturing sector from the literature. The second part compares seven frameworks, in terms of content and supply chain connectivity. Food sector specificity demands the inclusion of topics specific to food systems. Furthermore, none of the investigated frameworks fulfils both food sector specificity and full connectivity with the up- and downstream supply chain. As a limitation to this work, comparison of the frameworks at topic-level instead of indicator-level is considered. The findings call for more harmonised and integrated sustainability assessment throughout the food supply chain. The framework a food manufacturer should apply depends on their motivation behind conducting the sustainability assessment and reporting. Evidence is provided from various perspectives and with regard to key issues such as content, certification and communication. No comparison between sustainability frameworks has been made yet from the supply chain perspective of food manufacturers.

Financial performance and firm efficiency of automotive manufacturers and their suppliers A longitudinal data envelopment analysis

Brandenburg, M. ., & Hahn, G. J. (2021). Financial performance and firm efficiency of automotive manufacturers and their suppliers A longitudinal data envelopment analysis. Logistics Research, 14(1), 26. http://doi.org/10.23773/2021_01

Abstract

A data envelopment analysis (DEA) is presented to assess evolutions of firm efficiency and financial performance in automotive supply chains. A sample of 32 decision-making units (DMUs), 17 globally operating original equipment manufacturers (OEMs) and 15 key suppliers from the automotive industry, is in focus of this analysis in which cost levels and capital requirements are put into relation to sales growth and profit. Cost of goods sold, operating capital, and net fixed assets represent the financial input of a company while sales growth and earnings before interest and taxes (EBIT) reflect the financial output. The financial performance of a firm is indicated by its efficiency, calculated by an input-oriented variable returns to scale model. A multiple linear regression analysis reveals which operational performance factors are predictors of financial performance. A longitudinal DEA approach that covers the years from 2003 to 2017 is chosen to reveal performance evolutions over time. In order to analyze the stability of relationships between efficient firms (peers) and inefficient ones (followers) over time, changes in the performance relationship network are assessed in a graph-theoretic approach. In this study, geographical and structural specifics of DMU groups are taken into account. The study reveals similarities and differences between OEMs and their suppliers regarding the importance of value drivers and detects periods of performance losses and recovery from the global economic crisis.

Grid Services and Stress Reduction with a Flywheel in the Rotor of a Wind Turbine

Jauch, C. . (2021). Grid Services and Stress Reduction with a Flywheel in the Rotor of a Wind Turbine. Energies, 14. http://doi.org/10.3390/en14092556

Abstract

Wind power penetration increases in most grids and the sizes of wind turbines increase. This leads to increasingly tough requirements, which are imposed on wind turbines, both from the grid as well as from economics. Some of these partially contradictory requirements can only be satisfied with additional control mechanisms in the wind turbines. In this paper, such a mechanism, i.e., a hydraulic–pneumatic flywheel system in the rotor of a wind turbine, is discussed. This flywheel system supports a wind turbine in providing grid services such as steadying the power infeed, fast frequency response, continuous inertia provision, power system stabilization, and low voltage ride-through. In addition, it can help mitigate the stress on the mechanical structure of a wind turbine, which results from varying operating points, imbalances in the rotor, gravitation that acts on the blades, in-plane vibrations, and emergency braking. The study presented in this paper is based on simulations of a publicly available reference wind turbine. Both the rotor blade design as well as the design of the flywheel system are as previously published. It is discussed how the aforementioned grid services and the stress reduction mechanisms can be combined. Finally, it is concluded that such a flywheel system broadens the range of control mechanisms of a wind turbine substantially, which is beneficial for the grid as well as for the wind turbine itself.
