Özet
The agricultural and food processing sectors witness a daily increase in greenhouse gas (GHG) emissions, with food loss and waste (FLW) being a significant contributor. FLW have a monetary worth of US$1 trillion annually and contribute 8%-10% of all GHG emissions worldwide. Approximately 931 million tonnes of food waste are produced annually, making up over 17% of the globe's total food production in 2019. However, concerted action plans and measures can mitigate this issue. With the adverse impacts of climate change, declining crop yields, and a growing population, countries aim to halve food waste by 2050. Identifying FLW causes across the supply chain is crucial for implementing effective supply chain management strategies. Integration of green technologies like CLSC and short food supply chain enhances performance and reduces emission rates. Emphasis lies on resource optimization with minimal emissions throughout the supply chain. Digital technologies such as artificial intelligence, cloud computing, and Internet of Things significantly enhance communication and management practices, leading to more effective food waste prevention. While various biochemical approaches treat food waste for energy recovery, policy interventions strengthen sustainable supply chain management to cut GHG emissions. Though theoretical frameworks for achieving net-zero emissions are evolving, practical implementation efficiency remains uncertain. Prevention measures outweigh treatment methods, but stakeholder engagement is pivotal for success. Industrial-scale emission prevention from energy sources during food waste valorization remains challenging. This chapter explores the various opportunities and strategies for establishing a sustainable food supply chain, addressing observed drawbacks in supply chain management. Methodologies include food waste prevention, zero solid-waste disposal, green disposal technologies, and valorization towards achieving net-zero emissions.
