In this study, the design and sizing of a shredding shaft are presented. This shaft allows shredding the organic household waste inside the autonomous rotary composter before starting the composting process to accelerate the composting process, increasing the surface between the wastes to promote aerobic degradation and produce high-quality compost. In addition, this shaft of 30 mm diameter, made from stainless steel, does not consume much energy, 2,55 Kw. It rotates at a speed of 350 rpm for up to 5 min before the start of the composting process. The electric motor's power is transmitted to the shredder shaft through a pulley-belt transmission system. It allows the shaft to withstand maximum stress of up to 420.3 MPa, with a safety factor of 2,03. This design has been well studied and approved according to the 3D design software SolidWorks simulations.
