Food waste management is crucial for sustainability. Strategies include waste reduction, donation, and conversion into biofuels or biopolymers, with composting for nutrient recovery and carbon sequestration.
Area of Science:
- Environmental Science
- Sustainable Agriculture
- Waste Management
Background:
- Food waste is a significant global issue across the entire supply chain.
- Sustainable management of food waste is critical for environmental and public health.
- Current practices face challenges in collection, disposal, and resource recovery.
Purpose of the Study:
- To provide a comprehensive analysis of food waste definitions and reduction methods.
- To review emerging conversion technologies for food waste utilization.
- To highlight recent trends in sustainable food waste management.
Main Methods:
- Literature review of scientific discourse on food waste.
- Analysis of waste management hierarchy principles applied to food waste.
- Examination of conversion technologies for biofuels, biopolymers, and nutrient recovery.
Main Results:
- Food waste reduction strategies range from avoidance and donation to industrial conversion.
- Biofuel and biopolymer production are key industrial applications of food waste.
- Composting offers nutrient retrieval and carbon sequestration benefits.
Conclusions:
- Effective food waste management requires a multi-faceted approach, prioritizing reduction and reuse.
- Further research is needed in biomaterial development and advanced waste processing.
- Integrated strategies are essential for sustainable food waste solutions across all sectors.

In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
