Abstract:
... Based on a survey of 3,504 consumers in the United States, this study investigates acceptance for food with varying types of aesthetic imperfections. A product-based discrete choice experiments (DCE) were utilized to provide preference estimates based on trade-offs between attributes of aesthetic imperfections and other relevant product attributes including price and type of production and origin. ...
... To analyze the flow characteristics of the gas-mixed high solids anaerobic digestion (HS-AD) system and optimize the mixing performance, the mixing performance of gas and non-Newtonian fluid in the HS-AD system was investigated using the CFD simulation. The mixing energy magnitude, input pattern and nozzle inlet angle were optimized by evaluating available mixing indices. The performed experiments ...
... Institutions such as hospitals and schools waste approximately seven to eleven billion pounds of food annually in the US. Food composting can be utilized to divert food waste from entering landfills. This study explored behaviors and perceptions of staff and management involved in a composting intervention at a local hospital through the Diffusion of Innovation (DOI) theory. The importance of mana ...
... This is pilot study designed to ascertain college students' understanding of domestic food waste management using an online questioner. The descriptive results section of the report is used to describe the central tendency of the data collected for each variable. Meanwhile, the people who took part in the research were all part of a webinar on waste management that was led by people from universit ...
... Consumer intention to avoid food waste is determined by various socio-demographic and psychographic/psychological factors. While many of these factors have been well studied, some remain under-researched. This is the case for religious values and family upbringing that may represent strong antecedents of personal norms towards food waste avoidance. This study tests the role of these factors on a s ...
... Consumer food waste, like many environmental behaviours, takes place in private, and is not directly subject to social monitoring. Nevertheless, social interactions can affect private opinions and behaviours. This paper builds an agent-based model of interactions between consumers heterogeneous in their sociability, their initial opinions and behaviours related to food waste, and their willingness ...
foodwaste, etc ; economic valuation; national surveys; Australia; Show all 4 Subjects
Abstract:
... Households are responsible for a significant amount of food waste, estimated to be around 50% of economic value in developed countries. This food waste emerges from the complex interplay of behaviours associated with the planning, shopping, storing, preparing and disposing practices of food provisioning. Three segments were identified based on analysis of behaviours measured in a national survey i ...

Abstract:
... Surplus foods are fresh raw material of food that has not been processed, and a large number of surplus foods are discarded and wasted every day. As a new business model, a surplus food blind box can attract consumers to purchase to reduce food waste. The main purpose of this study is to find out how to improve consumers’ degree of cognition of surplus food blind box to improve the purchase intent ...
... Household food waste is a major sustainability problem to solve. Smart labels can alleviate the contributing factor of incorrect interpretation of expiration date labels. However, so far little research has studied consumer handling practices and perceptions of such labels in the context of use. We address this through a qualitative, asynchronous and text-based focus group study with 18 UK smart l ...

Abstract:
... So far, digital technology development in agriculture has mainly dealt with precision agriculture, often associated with conventional large-scale systems. The emergence of digital agriculture - based on the triptych of “new data sources / new processing methods / new inter-connection capacities (internet)” - opens up prospects for mobilizing digital technologies to accelerate the deployment of oth ...

Abstract:
... The effectiveness of producing n-caproate from food waste without external electron donors (EDs) was investigated through batch and semi-continuous fermentation. The maximum concentration of n-caproate reached 10,226.28 mg COD/L during semi-continuous fermentation. The specificity for n-caproate was the highest at 40.19 ± 3.95%, and the soluble COD conversion rate of n-caproate reached up to 22.50 ...

Abstract:
... Recently, conductive materials (i.e., carbon-based and iron-based materials) as a feasible and attractive approach have been introduced to anaerobic co-digestion (ACoD) system for promoting its performance and stability through direct interspecies electron transfer. Owing to the key roles of conductive materials in ACoD process, it is imperative to gain a profound understanding of their specific f ...

... Surplus food redistribution (SFR)ishailedas a ‘win-win’ strategy to address both household food insecurity and foodwaste.However,SFR is condemned as being a ‘band-aid’ solution that addresses neither the fundamental socio-economic causes of poverty,nor thesystematic roots of food waste.This research aims to set an agenda for the future of SFR in the UK for the next five to 10 years, including poli ...

Abstract:
... The interest surrounding consumer food waste behavior has been increasing in the academia and civil society, with academic research focusing on understanding its causes and testing interventions to reduce it. This paper aims to understand how to influence consumer food waste behavior with interventions and what further research is needed. For this purpose, a systematic literature review of 96 pape ...

Abstract:
... Worldwide, approaches inspired by the Circular Economy model have been increasing steadily, generating new business opportunities such as the recovery of high‐added value molecules (e.g., pigments) from vegetable food waste that may be applied as food additives (e.g., colorants). Indeed, food waste is a global problem that does not seem to be decreasing, leading to economic, environmental, and soc ...

Abstract:
... Food waste is a serious problem with regard to social equity and environmental challenges across the world. In recent decades, a dramatic growth of restaurant food waste has been seen in China. This study integrated the norm activation model (NAM), Chinese cultural values (i.e. face saving and group conformity) and information publicity to examine young Chinese consumers’ food waste behaviors in a ...
