Food waste's influence on the environment and on food security has become a global issue. According to previous estimates, between one-third and half of the world's food, or around 1.3 billion tons, is wasted. This is related to the overconsumption of natural resources: food waste accounts for 10% of greenhouse gas emissions in developed nations and consumes 550 billion cubic meters of water globally. Despite these figures, the world produces twice the amount of food required to meet the nutritional requirements of each live human.

L'influenza dello spreco alimentare sull'ambiente e sulla sicurezza alimentare è diventata una questione globale. Secondo stime precedenti, tra un terzo e la metà del cibo mondiale, ovvero circa 1,3 miliardi di tonnellate, viene sprecato. Questo è legato al sovraconsumo di risorse naturali: lo spreco di cibo rappresenta il 10% delle emissioni di gas serra nei paesi sviluppati e consuma 550 miliardi di metri cubi di acqua a livello globale. Nonostante queste cifre, il mondo produce il doppio del cibo necessario per soddisfare le esigenze nutrizionali di ogni essere umano vivo. Infatti, con meno di un quinto del cibo che sprechiamo, potremmo far uscire dalla povertà quasi un miliardo di persone affamate nel mondo. Se le attuali tendenze di consumo continuano, l'offerta di cibo dovrebbe aumentare del 70% per nutrire i 9 miliardi di persone del mondo nel 2050. Queste statistiche globali dimostrano la necessità essenziale di affrontare lo spreco alimentare. I consumatori sono i principali generatori di rifiuti, che ha portato as un aumento della quantità di spreco alimentare domestico negli ultimi anni a causa del cambiamento degli stili di vita, della rapida industrializzazione e dei cambiamenti socioeconomici e demografici. Le dimensioni e la composizione della famiglia hanno un effetto sulla quantità di cibo sprecato, con le famiglie più grandi che sprecano meno cibo delle famiglie più piccole. Esaminando chi spreca di più e cosa viene sprecato, così come i fattori che contribuiscono alle abitudini e alle azioni di spreco alimentare, e come i consumatori fanno scelte alimentari e i fattori che influenzano le scelte sostenibili, l'obiettivo di questa tesi è di comprendere queste implicazioni, identificare potenziali opportunità di design, e concettualizzare una soluzione adeguata che affronti il problema. La soluzione proposta consiste in un sistema di monitoraggio in tempo reale della freschezza degli alimenti domestici basato su sensori di gas o indicatori di freschezza in grado di rilevare i composti volatili emessi dagli alimenti prossimi al deterioramento. Il sistema consiste in diversi contenitori adatti a diverse categorie di cibo con un sensore incorporato o inserito all'interno, che è in grado di comunicare lo stato del cibo in tempo reale con l'utente tramite uno smartphone, aiutare il consumatore a dare priorità e ricordare all'utente l'esistenza di prodotti che devono essere consumati prima e ottimizzare la gestione dei prodotti alimentari nel contesto domestico.

Abstract
Food waste's influence on the environment and on food security has become a global issue. According to previous estimates, between one-third and half of the world's food, or around 1.3 billion tons, is wasted. This is related to the overconsumption of natural resources: food waste accounts for 10% of greenhouse gas emissions in developed nations and consumes 550 billion cubic meters of water globally. Despite these figures, the world produces twice the amount of food required to meet the nutritional requirements of each live human. Indeed, with less than a fifth of the food we squander, we could bring the world's almost one billion hungry people out of poverty. If current consumption trends continue, food supply would have to increase by 70% to feed the world's 9 billion people in 2050. These global statistics demonstrate the essential need of addressing food waste. Consumers are the primary generators of waste. For instance, home food waste has increased in recent years as a result of changing lifestyles, rapid industrialization, and socioeconomic and demographic shifts. The size and composition of the household have an effect on the amount of food wasted, with bigger households wasting less food than smaller families. By examining who wastes the most and what is wasted, as well as the factors that contribute to food waste habits and actions, and how consumers make food choices and the factors that influence sustainable choices, the objective of this thesis is to comprehend these implications, identify potential design opportunities, and conceptualize a proper solution that addresses the problem. The proposed solution consists of a real-time freshness monitoring system for household food based on gas sensors or freshness indicators capable of detecting volatile compounds emitted by food close to spoilage. The system consists of several containers suitable for different categories of food with a sensor embedded or inserted inside, which is able to communicate the status of the food in real time with the user via a smartphone, help the consumer to prioritize and remind the user of the existence of products that need to be consumed sooner and optimize the management of food products in the household context.File | Dimensione | Formato | |
