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.

Abstract
The study at hand elaborates on potential barriers, prerequisites and optimization potentials for the automation of the twistlock handling process in container terminals. A case analysis enlightens latest automation developments of this essential task in container transport. Eight experts from different organizations in maritime logistics and seaport operations were interviewed in a qualitative multiple-case research design. The interviews were evaluated by qualitative-quantitative content analysis with MAXQDA software. Automated twistlock handling systems are hardly implemented, although they represent the missing link between other container handling technology in the automated container transport. The study reveals that most implementation barriers consist of technological issues, followed by economic and strategic barriers. The study identifies implementation strategies and their key success and shows that safety improvements and cost reductions are major benefits of this automation. An innovation framework for this field of automation is conceptualized as scientific contribution. Practical implications include recommendations for relevant stakeholders in container logistics.

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.
