Abstract
AbstractFood waste treatment technology should be simple to maintain, quick, economical, environmentally friendly, and socially acceptable. This research aims to accelerate food waste treatment and produce high‐quality fertilizer using a smart food recycling bin (S‐FRB). S‐FRB is a portable household‐appropriate technology, consisting of a semiautomatic chopper, stirrer, and drying unit. In this smart bin, a highest matrix temperature of 57 °C can be achieved. To start compost production, addition of a combination including a bioactivator (16 g) + dolomite lime (1 g) + bulking agent to the food waste in a ratio of 70:30, v/v is needed. During utilization, the water content decreases from 78.94% to 30% in 7 days, and the pH matrix turns from initially 7.5 to 8.0. Compost produced from food waste using the S‐FRB has matured within 7 days and meets quality standards of SNI 19‐7030‐2004. The produced compost has 18.41% C‐organic, 1.23–1.63% total N, smells like soil, and is black. The used combination of bulking agent/bioactivator/lime is effective for processing food waste into compost. The S‐FRB system is a practical way to solve the problem of recycling food waste into compost without having to be taken to a final processing plant.
