Abstract
AbstractZoo waste is a common problem in urban areas, as it overloads municipalities. To enhance the park's appeal, sustainability, and cleanliness, a pilot vermicomposting process was implemented as an alternative for organic waste disposal. It aimed to address the negative effects of poor organic waste management. Three types of pond water, namely hippopotamus, crocodile, and gharial, were recycled. Additionally, ostrich droppings and the nitrogenous compounds abundant in carnivore feces were utilized. The study sought to improve organic waste management and recycle pond water using exotic worms. Chemical and physical analyses were conducted on pond water and vermicompost obtained from Gandhi Zoological Park, revealing their high nutrient content. Fourier transform infrared spectroscopy was employed to study the functional groups present in the compost and vermicompost, allowing the detection of vermicompost maturity. The biomass of exotic earthworms, as well as the count of cocoons, juveniles, and adults, was assessed during different seasons of the year. This approach facilitated the recycling of pond water and the reduction of organic waste within the zoo premises. It involved the symbiotic cooperation of earthworms and bacterial colonies, transforming the waste into a high‐quality product with balanced macro nutrients. The novelty of the study lies in its focus on nutrient recycling in pond water, ostrich droppings, and vermicomposting of organic waste from carnivores.
