Disposing of fruit and vegetable peels in landfills generates methane gas emissions and wastes potentially valuable resources. These agricultural by-products provide a rich supply of nutrients, minerals, and vitamins, including dietary fibre, anthocyanins, ascorbic acid, and phenolic compounds. Feeding these peels to animals can improve their overall health and productivity, leading to enhanced meat and milk yields from livestock, alongside improved drawing power in draught animals. Repurposing peels as animal feed presents clear ecological benefits by lowering organic waste build-up and reducing the greenhouse gas emissions linked to waste decomposition. Furthermore, substituting peels into animal diets lessens reliance on conventional feed ingredients such as grains, which typically require resource-intensive farming practices. Integrating fruit and vegetable peels into feed regimes offers a balanced approach that supports livestock performance while addressing environmental sustainability challenges.
Discarding fruit and vegetable peels contributes to landfill burden and greenhouse gas emissions, despite their high nutritional content. Repurposing these by-products into animal feed offers a dual solution: it cuts down organic waste and emissions while providing livestock with essential nutrients. This approach also diminishes the demand for resource-heavy conventional crops, supporting more sustainable agricultural food systems.
Livestock farmers and animal feed manufacturers could use fruit and vegetable processing residues as alternative feed ingredients to replace resource-heavy grains. This application directly targets agricultural efficiency and waste reduction. As a broad review of nutritional and environmental impacts, the findings sit at an early conceptual stage, identifying potential feeding strategies rather than outlining specific, ready-to-market feed manufacturing processes.

ABSTRACT Fruit and vegetable peels are often regarded as waste, leading to their disposal in landfills. As a result, methane gas emissions during the decomposition of waste lead to the loss of potentially valuable resources. Nonetheless, these peels are an abundant source of nutrients, minerals, and vitamins such as dietary fiber, anthocyanins, ascorbic acid, and phenolic compounds, which can enhance animal health and productivity and, as a result, increase the milk and meat production of livestock as well as the drawing power of draught animals. From an environmental perspective, the utilization of peels for animal feed can significantly reduce organic waste accumulation, decrease greenhouse gas emissions associated with waste decomposition, and lower the dependency on conventional feed ingredients such as grains, which are often produced through resource‐intensive agricultural practices. To date, no comprehensive review has been found on the nutritional and environmental impact of fruit and vegetable peels as animal feed. This paper aims to explore the nutritional and environmental impact of various kinds of fruit and vegetable peels.
