My style,my food,my waste! Consumer food waste-related lifestyle segments

Adapting responsible food marketing practices to different customer types can make a valuable contribution to reducing food waste. The current study investigated the relation between food (waste)-related lifestyle patterns and self-reported food waste, choices for suboptimal food, and food waste awareness using a survey with 4214 consumers across five Northern and Western European countries. Results show differences in food wastage, suboptimal choices, and awareness for five clusters of consumers identified on the basis of food (waste)-related lifestyle patterns. Findings of commonalities allow deriving food marketing actions targeted to these different consumer lifestyles.     

Recovering Sociology from the Trash Heap: Of Waste Politics and the Spatialization of Local Representation in Lagos

This article excavates the debate that unfolded during the 1980s between Jacques Rancière and Pierre Bourdieu to shed light on the theoretical divide that still cuts across the field of urban studies today. Looking at contemporary Rancièrian scholarship through a Bourdieusian lens, it points to their main theoretical shortcomings and reasserts the value of relational, field‐based and empirically grounded approaches to urban politics. At the same time, this article engages seriously Rancière's critique of Bourdieu's failure to account for space in order to question the territoriality inherent to the notion of field. We put this theoretical discussion to the test of Lagos's garbage. Drawing on an ethnographic study conducted in Lagos from 2015 to 2016, we propose analyzing the process of spatialization of the field of local representation by looking at the ways solid waste—here conceived as a political opportunity—is mobilized by different actors. We argue that the deployment of a waste infrastructure in Lagos is congruent with a relative disinvestment in practices of territorial control that reshapes the structure of local representation, reconfiguring the ‘stage’ on which politics is played out in the Nigerian metropolis.     

Advancing environmental productivity: Organizational mindfulness and strategies

This study investigates the importance of mindfulness‐based organization systems and policies on the organization's continuous efforts to become a greener company. The study is devised as a pooled cross‐sectional time series analysis of productivity in energy consumption, water utilization, and waste generation and recycling of U.S. companies. The data set taken from U.S. Newsweek 500 recorded 600 companies dispersed into 63 industries during the period of 2012–2014 and provided 1,498 company–industry–year observations. The study found that systems and policies (e.g., deployment of third‐party auditors for its environmental metrics report; linkage of the remuneration of company's senior executive team with the achievement of environmental performance targets; and establishment of a committee at the Board of Directors' level whose mandate includes sustainability of the company in environment‐ and resource‐related matters) connect the company's mindfulness to its effort in improving the environmental quality through the company's productivity in energy consumption, water utilization, and waste generation and recycling. The relationships are positive and significant. Also, systems and policies serve as a motivator for the firm to continue to improve upon the current achievements. The study emphasizes the importance of translating organizational and individual mindfulness into organization policies and systems in order to motivate the organization to continuously improve its productivity in energy consumption, water utilization, and waste generation and recycling leading to improvements in environmental quality.     

Helping You to Waste Less? Consumer Acceptance of Food Marketing Offers Targeted to Food-Related Lifestyle Segments of Consumers

ABSTRACT

Consumer households and consumer behavior have been identified as the major cause of food waste in the supply chain. Food marketing might offer products and services that help consumers to reduce their food waste or reduce the consumer-related food waste at the consumer–retailer interface. However, such strategies require consumer acceptance and targeting the right customers. Through an online survey of 800 Danish consumers and a measure of food-related lifestyle, four clusters of consumer segments are identified. The segments are compared with regard to their acceptance of a number of actions consumers can take to reduce food waste or their acceptance of food marketing services they would need to pay for. Acceptance differs with food involvement and the role of the price criterion, as well as with gender, education and age. The findings show how food marketing can help consumers to reduce food waste, through actions targeted to specific segments of consumers characterized by food-related lifestyle differences.     

Household Food Waste Solutions for Behavioral Economists and Marketers

ABSTRACT

Household food waste originates in three predictable stages – when shopping, storing, and serving. That is, food can be purchased and never prepared, prepared and never served, or served and never eaten. Building on behavioral economics insights, this framework focuses on why consumers waste food in these three stages and how marketers can help consumers reduce food waste and thereby help them get more value from their products by enjoying them more and wasting them less. For cost-conscious consumers, wasting less means saving more. For profit-conscious marketers, wasting less means making more profit.     

Are Social Costs the Outcome of Struggles over Truth?

Abstract:

This article critically examines the institutional economics theory of social costs by way of reviewing The Dark Places of Business Enterprise: Reinstating Social Costs in Institutional-Economics (2019). In particular, the article assesses the proposal to re-root institutional economics in the theoretical synthesis of “Veblen-Kapp-Mirowski” to better understand the social costs of neoliberalism. One of the findings is that while such a synthesis seems justified on the grounds of significant commonalities and the merits of deeper insights, it nevertheless runs into difficulties due to divergent philosophical foundations. One of the conclusions is that further philosophic clarification is needed on how an alternative economy would understand the relationship between “social costs” and Truth.

Bioelectricity in Malaysia: economic feasibility,environmental and deforestation implications

We investigate the economic feasibility of bioelectricity production from biomass in Malaysia and its impact on greenhouse gas (GHG) emissions and storage, agricultural prices, agricultural employment and deforestation. For this purpose, we develop a partial equilibrium model that projects agricultural prices, production, imports, exports, domestic consumption and land use in 5‐year increments between 2015 and 2065. Our results show that by 2030 biomass‐generated electricity can supply 36.5 per cent of the electricity generated in Malaysia, 16 times more than the 2016 electricity supply from biomass. Increased bioelectricity production from biomass will significantly reduce GHG emissions and will help Malaysia meet its commitment in the Paris Agreement to mitigate GHG emission by 45 per cent before 2030. Our modelling shows that biomass‐generated electricity creates a derived demand for waste biomass that expands the area of oil palm plantations. The expansion lowers agricultural prices, boosts agricultural employment and leads to some deforestation as landowners clear rainforest to plant oil palm trees. Nonetheless, the deforestation does not increase GHG emissions since GHG gains from bioelectricity significantly exceed GHG losses from deforestation.     

Municipal solid waste management and greenhouse gas emissions at international airports: A case study of Astana International Airport

The steady expansion of the city of Astana and the increase of airport capacity is leading to an increase in municipal solid waste generation. The purpose of this study was to perform compositional analysis of the municipal solid waste produced at the Astana International Airport and evaluate different waste management scenarios in terms of greenhouse gas emissions. Recyclable and combustible fractions were found to be the major fractions (over 50%) of the total municipal solid waste generated in the Astana International Airport. Four base greenhouse gas emissions scenarios were proposed in this study, namely scenario-1 describing the current municipal solid waste management case, scenario-2 with integration of 29% recycling and 71% of municipal solid waste landfilling, scenario-3 for 100% of airport municipal solid waste being incinerated and scenario-4 for recycling 29% and the remaining waste being processed for energy recovery purposes. The proposed scenario 2 demonstrated significantly reduced net greenhouse gas emissions (t CO₂ eq/year) over the existing scenario 1, while scenarios 3 and 4 showed negative net greenhouse gas emissions. The experimental data provided and the scenarios discussed in this work are useful tools for decision makers for environmental waste management at airports.
