Flower waste from markets and events often ends up in landfills, contributing to the already serious environmental issues. In order to help lessen waste, this study presents a mechanical solution that aims to turn that waste into something useful — compost. This study developed an in-vessel aerobic composting machine that includes a rotating mixer, heating system, and sensors that check moisture and temperature to make sure to provide a high-quality compost that could lead the plants and crops to healthier growth and reduce the natural composting time of flower waste. These parameters contribute to a better environment and conditions for helpful
microorganisms to break down the flower waste faster than its natural composting cycle. The in- vessel machine lowered the composting cycle by around 10%-20% compared to traditional natural
composting methods. The output also showed good quality, with 5.0 to 8.0 pH levels which is the proper pH level for compost, and a balanced 30:1 carbon-to-nitrogen ratio, making it suitable for farming use. This design can help minimize the waste ending up on landfills and promote composting in urban areas in a practical, ecological and sustainable manner.
