The consumption of chicken is steadily increasing due to its high protein content. However, the resulting waste, particularly feathers, is often improperly discarded in lakes, rivers, open land, and ponds—contributing to environmental pollution. According to 2019 data, India consumed approximately 1,560 million chickens, generating around 31,200 tons of waste feathers. These feathers are typically treated as waste, leading to uncontrolled methane emissions, which negatively impact the environment. Anaerobic digestion presents an economical and efficient method to convert the proteins found in chicken feathers into methane gas. Utilizing this technique not only helps manage poultry waste but also provides a renewable source of energy. This can reduce dependence on fossil fuels, which are finite and increasingly unreliable for meeting growing energy demands such as vehicle fuel and electricity generation. Moreover, this approach supports a cleaner, more sustainable environment by minimizing pollution.
