DESIGN OF AN AUTONOMOUS SOLAR ROTARY COMPOSTER WITH SHREDDER SHAFT

Abstract

Composting is the most efficient technique for managing household organic waste; it is the most widely used technique in the world. To improve and accelerate the composting process and produce rich and stable compost, it is necessary to grind and shred organic waste into small pieces to facilitate the degradation of the material by microorganisms. This paper presents the design, sizing, and modeling of a new self-contained, solar-powered, rotating composter with a shredding shaft. This shredding shaft rotates at 350 rpm and must run for 5 minutes before starting the composting process. This innovative machine shreds and composts organic household waste in situ to produce stable, mature compost suitable for agricultural use, providing an effective solution for managing and recovering organic household waste.
