Food waste is a significant global issue, contributing to environmental and health concerns due to improper management. This project introduces an in-kitchen waste composter, Wace-Kit, designed for efficient fertilizer production using dehydration technology. The system incorporates an Arduino Uno as the central control unit, integrating temperature and humidity sensors for real-time monitoring and user interaction via an LCD display. A temperature selection switch enables users to optimize dehydration efficiency. The design was initially simulated using Proteus 8 software before being implemented as a functional hardware prototype. Three types of food waste—coffee grounds, eggshells, and fruit scraps—were tested, with dehydration performance evaluated based on moisture reduction. The system operates by allowing users to select a temperature setting, followed by automated heating, cooling, and ventilation. The study also explores the relationship between voltage, current, and power, assessing their impact on dehydration efficiency. Results indicate that coffee grounds achieved the highest dehydration percentage, demonstrating the system's effectiveness in food waste reduction and sustainable fertilizer production.
