2. Kitchen Waste will be Collected and characterized . Cost-effective, odor free Rotary decomposer will be designed and fabricated. Microbial Accelerator will be prepared. Composting will be carried out in the designed decomposer under controlled moisture content, C/N ratio and aeration. Compost is made and it is quality will be analyzed. And finally cost-benefit analysis will be carried out. 12/03/2024 First review, GCE- Tly 1 ABSTRACT

3. To design a cost-effective home composting solution for easy decomposing of home wastes, ensuring quick and odor-free decomposition. 12/03/2024 First review, GCE- Tly 2 AIM OBJECTIVE To collect and Characterize the kitchen waste generated from households. To fabricate in vessel composter ensuring quick and odor-free decomposition. To assess the performance of the composter by monitoring pH, Temperature and moisture content. To carry out quality and cost-benefit analysis of the compost.

12. 12/03/2024 First review, GCE- Tly 11 TOTAL SOLIDS AND TOTAL VOLATILE SOLIDS The empty weight of the dish of the dish is noted(W 1 ). The dish with the sample is transferred to hotplate and dry it under 60 ̊̊̊ c for one hour and cool it in desiccator .Weigh it as ( W 2 ). Then the dish is transferred to muffle furnace at 550 ̊̊̊ c and cool it in desiccator and then weigh it as (W 3 ). Total solids = (W 2 -W 1 ). Total volatile solids = ((W 2 -W 1 )-(W 3 -W 1 )).
