    In the present context, solid waste management from the house level is necessary and useful for reducing the load on the municipal dumpsite. Household composting is the best option to segregate and treat the organic waste at house level itself. For this, a uniquely designed shaft for household composter is developed and demonstrated along with processing bin, maturation bin, processing shaft, holding stand and leachate collection system. The processing shaft provides the four necessary actions, namely grinding, churning, turning and aeration in the composter while rotating. During the process of composting, it is found that, after every scheduled rotation of the shaft, the temperature increases inside the material. Because of grinding action of the shaft, the particle size of the final compost is 91.2% material passing from 4 mm sieve. The physical and chemical properties with heavy metals of the final compost, compliance the compost standard as per Indian guideline. The composter is compact, portable, mobile, detachable and cost effective for household organic waste.
