Household food waste in Greece: A questionnaire survey
The challenge of reducing Food Waste (FW) is a complex social, economic and environmental problem. Fortunately, the realization of FWs huge negative impact on society has triggered –in the last five years-a positive turn of focus towards the development of a common understanding of the phenomenon, the identification of its root causes and the initiation of coordinated actions to increase citizen awareness and mitigate negative consequences of FW at all levels of the food supply chain. This paper focuses on the last downstream tier of the food supply chain, i.e. the households, which are reported in literature as being responsible for eight times the energy waste of post-harvest losses on average due to the energy consumed along the supply chain and in food preparation. This study attempts to investigate the effects of shopping habits, like promotional intensive shopping and using shopping lists and eating preferences, like cooking, eating out or ordering in, on food waste generation. In doing so, the results of a survey of 500 Greek households are presented, showing that indeed, household behaviours towards shopping and eating are important food waste determinants and should not be underestimated. Furthermore, the results of this study highlight the need for more research targeted in this area, with the objective to increase consumers' awareness and problem comprehension, enhance their commitment and create the necessary environment for triggering meaningful behavioral changes capable of creating long-term and sustainable results.

Development of a Blockchain-based Technology Solution for Tackling Food Waste and Supporting Food Insecure People
This project introduces a technology-driven solution to address food waste in food-service establishments by connecting surplus food with people in need.
By leveraging Blockchain technology, it creates an online platform for real-time communication and efficient allocation of excess food.
Through a mobile application, establishments can upload surplus food data, which is then rewarded and made accessible to food insecure individuals.
This integrated system aims to minimize waste while providing crucial aid to those facing food insecurity, promoting a more sustainable and equitable food ecosystem.

Utilizing Blockchain Technology to Tackle Food Waste in Smart Cities
Food waste is a pressing global concern, contributing to significant environmental and socio-economic challenges, while millions face food insecurity worldwide.
In urban areas with thriving food businesses, surplus meals often end up in the trash due to inaccurate forecasting.
This research introduces a Blockchain-based solution enabling food-service establishments to offer excess meals to those in need.
By facilitating communication between businesses and food insecure individuals, the project aims to reduce waste and provide nutritious meals. The integrated system, accessible via a mobile platform, strives to create a marketplace for surplus food, fostering smart city initiatives and supporting vulnerable members of society with the anonymity and security of Blockchain technology.

A Blockchain-based Application for Food Waste Reduction
This research project introduces a novel solution to the intertwined issues of food waste and food insecurity in urban areas.
Using blockchain technology, a decentralized mobile application (dApp) is proposed to incentivize food waste reduction and provide nutritious meals to those in need.
Citizens use project tokens to purchase surplus food from participating establishments, which receive tokens in exchange.
The paper outlines the dApp's architecture and discusses tokenization processes, offering a promising approach to address these pressing challenges.

Development of a Blockchain Ecosystem Based on the Tokenization of Food Waste
The coexistence of food waste and food insecurity is a paradox of modern times, especially in the urban environment.
In this context, the core objective of the project presented in this paper is to develop a decentralized application (dApp) running on mobile devices, for
reducing food waste by providing safe and nutritious meals, mainly to food insecure citizens.

Mapping the Causes, Effects and Technological Opportunities for a Sustainable Future
This paper reviews the significant issue of food waste in the food service and hospitality sector, which contributes to environmental degradation and food insecurity.
Despite increasing awareness, there is a lack of comprehensive research on this topic.
The paper explores causes, effects, and technological solutions, highlighting the need for standardized methodologies to assess and manage food waste.
While various programs exist globally to mitigate waste, a universally applicable framework is still absent.
The paper emphasizes the importance of adopting innovative technologies and practices to address this pressing issue and create a more sustainable food system.

When is it Really Dead? Ethnographic Reflections on Animals as Food and (Food) Waste
In this paper I present some ethnographic observationson the cultural processes by which an ingredient can be food or waste.
More specifically, I wonder how the senses, values and cultural perceptions of edibility transmute food into waste and waste into food.
I ask: how do people perceive food waste?
What renders foods inedible? Is it just the expiration dates or is it a more complex process?
What is the role of the senses, values and culture in the shaping of behaviors and attitudes around food waste, especially when it comes to animal foods?
How are food waste practices and attitudes shaped?

An Innovative Layout Design and Storage Assignment Method for Manual Order Picking with Respect to Ergonomic Criteria
This paper proposes an innovative approach to enhance manual warehouse Order Picking (OP) processes. It focuses on designing a picking area layout and storage assignment strategy considering ergonomics and workers' fatigue.
By categorizing picking slots based on size and ABC analysis, and incorporating ergonomic constraints, such as rack heights and travel distance restrictions, the method introduces a 'flame-shape' aisle layout.
Products are then assigned to optimal locations using a ranking system based on factors like weight, popularity, and slot location.
Results show a 14.9% increase in productivity and a 31% decrease in the 'difficulty' index, demonstrating significant performance improvement through minimized travel distance and workload.

Building a Sustainable Future: A proposed technology solution for demand response management based on blockchain in smart grid
Smart grid technology is gathering significant attention, as the world transitions to cleaner and more sustainable energy systems in order to gradually tackle climate change.
The critical requirement for rapid decarbonization has led to a reduction in the usage of fossil fuels and the integration of zero-carbon renewable energy sources, electric vehicles and heat pumps.
As a result, the complexity of electricity grids has increased, rendering the balance between electricity supply and demand vital.
