Gamified eco-points and cost salience—when rewards “do” and “do not” align in anti-food-waste apps

In the burgeoning landscape of digital solutions aimed at combating food waste, anti-food-waste applications are increasingly employing gamified "eco-points" to encourage sustainable consumer choices. However, the precise conditions under which these reward systems effectively align with consumer motivations, or conversely, fail to do so, remain unclear, particularly in scenarios where the cost of goods is highly salient. A recent study delving into consumer intentions toward sustainable food platforms has shed light on the intricate interplay between gamification, cost awareness, and trust cues in shaping user engagement.

The research, conducted in Taiwan, employed a mixed-methods approach, beginning with semi-structured interviews with experts in interaction design, food co-op operations, and secondary education. These qualitative insights helped to identify key design levers and potential pain points within existing platforms. This was followed by a cross-sectional survey of 256 Taiwanese consumers, who rated their cognition, platform demand, reward perceptions, trust and traceability cues, assortment preferences, and price acceptance on a 5-point Likert scale. The study reported strong reliability and construct adequacy, with a Cronbach’s alpha of 0.949 and a KMO value of 0.938, indicating the robustness of the data for factor analysis.

Key Findings: A Nuanced View of Consumer Motivation

Exploratory factor analysis revealed four significant components that explained 63.09% of the variance in consumer perceptions: sustainability cognition, platform enablement, reliability and traceability, and cost and education salience. Consumers generally endorsed the potential of sustainable food platforms, rating educational content (mean=4.10) and third-party product certificates/traceability (mean=4.27) as particularly important. However, the willingness to pay a price premium for these sustainable options was modest (mean=3.32), highlighting cost salience as a significant barrier to widespread adoption.

While "eco-points" were viewed favorably (mean=3.92), an importance-performance map analysis (IPMA) indicated that they ranked below crucial reliability information. This suggests that even attractive gamified rewards may not be sufficient to drive sustained engagement if the foundational elements of trust and perceived value are not adequately addressed. Transparency gaps, such as missing test reports or real-time verification, were found to erode consumer trust.

The study also identified that occupation moderates platform demand, with individuals in the finance and insurance sectors showing higher demand compared to those in the public sector or retired groups. This suggests that professional backgrounds and financial literacy may influence how consumers perceive the value and economic feasibility of sustainable food platforms.

The Conditional Power of Rewards

A crucial insight from the research is that rewards, such as eco-points, are most effective when foundational trust and perceived value are strong, and when the cost of the food is not a primary concern for the consumer. When price salience is high, however, transparent reliability cues and educational framing emerge as dominant factors influencing behavior. In these scenarios, eco-points function best as supplementary motivators rather than primary drivers of consumer action.

This finding has significant implications for the design of anti-food-waste applications. The study suggests a strategic approach:

• Prioritize Transparency and Traceability: Platforms should emphasize real-time verification, third-party certifications, and end-to-end traceability to build robust consumer trust.
• Integrate Rewards with Cost Offsets: To mitigate the impact of high price salience, eco-points could be paired with tangible benefits like bundle discounts or special offers.
• Expand Assortment: Offering a wider variety of products can help reduce search costs for consumers and increase the overall attractiveness of the platform.
• Enhance User Experience: Ensuring fast confirmations and readily available in-app customer support can address common pain points and foster a sense of reliability.

Background and Context: The Growing Challenge of Food Waste

The global issue of food waste has become increasingly prominent in discussions surrounding sustainable development. The Food and Agriculture Organization of the United Nations (FAO) estimates that approximately 1.3 billion tons of edible food are wasted annually worldwide, a stark contrast to the hundreds of millions who suffer from hunger. This paradox underscores systemic inefficiencies in food production, distribution, and consumption. In urban environments, a significant portion of this waste originates at the retail and catering levels, driven by factors such as overproduction, stringent aesthetic standards, misinterpretation of expiry dates, and inefficient logistics.

In response, a wave of sustainable food platforms and anti-food-waste digital applications has emerged. These platforms, while often incorporating Web 2.0 features like user interaction and content sharing, are primarily focused on facilitating food redistribution, rescue, and promoting sustainable consumption. Examples include Tasteme and the Homemakers Union Consumers Co-op in Taiwan, Too Good To Go in Europe, No Food Wasted in the Netherlands, and OLIO in the UK. Each platform exhibits unique characteristics shaped by its cultural context, market structure, and policy environment.

Expert Insights Shape Design Recommendations

The initial phase of the study, involving expert interviews, provided critical qualitative data that informed the quantitative survey design. Experts highlighted the importance of user experience, with a streamlined interface and clear information architecture being crucial for adoption. Conversely, pain points such as insufficient real-time customer service, delayed confirmations, and inadequate disclosure of product verification information were identified as significant detractors from user trust and platform reliability.

These experts proposed four key directions for platform improvement: enhancing real-time verification and traceability, integrating cost-offset mechanisms with gamified rewards, expanding product assortment to reduce search costs, and optimizing user interaction through fast confirmations and responsive customer support.

Consumer Perceptions: A Closer Look

The survey data revealed that while consumers generally understand the importance of sustainable food for environmental protection and food security (means ranging from 3.81 to 4.28 for related items), translating this awareness into action remains a challenge. The modest willingness to pay a price premium (mean=3.32) is a critical indicator of this gap. Consumers highly value product certificates and traceability (mean=4.27) and educational content (mean=4.10), suggesting that informed decision-making is paramount.

Regarding platform demand, the study found that while occupation had a statistically significant influence, the effect size was relatively small. The finance and insurance industry respondents showed higher demand, potentially due to a greater familiarity with cost-benefit analyses and digital transaction platforms. This suggests that an individual’s professional context can shape their perception of value and risk associated with sustainable food initiatives.

The Role of Trust and Mediating Factors

The research further explored the mediating role of platform trust and loyalty in the relationship between reward sensitivity and continued usage intention. The findings indicated that eco-point rewards primarily influence continued use when they successfully enhance user trust and foster a sense of relational attachment to the platform. This suggests that trust is a foundational element, and rewards serve as a secondary, albeit valuable, reinforcement mechanism.

Crucially, the study found that price salience moderates the effectiveness of rewards. When consumers perceive high price pressure, the positive association between reward perception and their intention to use the platform weakens significantly. This implies that for consumers highly attuned to cost, the appeal of gamified incentives diminishes when faced with potentially higher prices for sustainable products.

Implications and Future Directions

The study’s findings offer valuable guidance for platform developers, policymakers, and sustainability advocates. The emphasis on transparency, reliability, and tangible value propositions, rather than solely relying on gamification, is critical for fostering sustained consumer engagement with anti-food-waste initiatives.

Limitations of the study include its cross-sectional design and its focus on a Taiwanese consumer sample. Future research could benefit from experimental designs to establish causal relationships more definitively and to test these findings across diverse cultural and economic contexts. Longitudinal studies would also provide deeper insights into the long-term effectiveness of different motivational strategies.

Ultimately, the success of anti-food-waste applications hinges on their ability to build and maintain consumer trust, provide clear value, and address economic concerns. While gamification can play a supporting role, it is the foundational elements of transparency, reliability, and perceived benefit that will drive the widespread adoption of sustainable food consumption practices.
