Biodegradable Nonwovens with Poultry Feather Addition as a Method for Recycling and Waste Management

Area of Science:

• Materials Science
• Environmental Science
• Agricultural Science

Background:

• Geotextiles are essential in civil engineering for soil stabilization and erosion control.
• Nonwoven geotextiles require effective biodegradation strategies for environmental sustainability.
• Poultry feathers represent a keratin-rich waste stream with potential for biodegradation enhancement.

Purpose of the Study:

• To investigate the impact of poultry feather addition on the biodegradation rate of nonwoven geotextiles.
• To assess the ecotoxicity and microbiological effects of feather-amended geotextiles in cultivated soil.
• To determine the correlation between material properties, biodegradation, and agricultural application potential.

Main Methods:

• Laboratory-based biodegradation tests assessing weight loss of nonwoven geotextiles.
• Ecotoxicity evaluation through monitoring microbiological activity (cfu).
• Determination of the carbon to nitrogen ratio in the soil test medium.
• Statistical analysis of mechanical properties and biodegradation period.

Main Results:

• Poultry feather addition significantly accelerated geotextile biodegradation, with decomposition occurring within 8-24 weeks.
• No adverse effects on soil microbiological activity (10^6 cfu) were observed.
• A correlation was established between mechanical properties and the biological decomposition timeline.
• The carbon to nitrogen ratio shifted with feather addition, indicating altered decomposition dynamics.

Conclusions:

• Poultry feathers effectively enhance the biodegradation of nonwoven geotextiles in soil.
• The feather-amended geotextiles are ecotoxicologically safe and promote soil health.
• This approach offers a sustainable "golden solution" for managing poultry waste in agriculture, providing nutrients and eco-friendly material management.
