Experimental study of consuming horse bedding for re-bedding and energy production in Tehran

The quality of stable environments is crucial for maintaining the health of horses, minimizing air pollution, and potentially utilizing waste for fuel production. This study investigates the physical, chemical, and biological characteristics of dry horse bedding across twenty-four horse-riding clubs in Tehran. The objectives are to gather information on current stable practices and assess the suitability of used bedding for reuse or energy generation. Results revealed that the moisture content of the bedding ranged from ۳۹.۶۳% to ۷۶.۹۲%, leading to high drying costs. Ash content varied between ۷.۷۳% and ۱۷.۲۰%, while nitrogen content ranged from ۰.۷۸% to ۱.۷۷%. Hydrogen content was measured between ۷.۰۶% and ۹.۰۴%, with carbon content ranging from ۱۴.۷۴% to ۲۴.۴۶%. The particle size distribution showed that ۷۰% to ۹۴% of particles were smaller than ۳.۱۵ mm, with ۰.۵% to ۱.۵% below ۰.۰۷۵ mm, indicating potential health concerns. The average gross calorific value was ۱۹.۰۳۷۲ MJ/kg. While the pellet samples did not meet specifications for non-industrial use, used horse bedding pellets exhibited greater suitability for industrial applications.
