However, it is not efficient, as it relies on natural processes to produce compost. Making a composter that efficiently reduces waste and creates a more sustainable lifestyle would be a solution.  Therefore, this study aims to design and develop a low-cost compost-preparing machine for the common people to fertilize their lands with their self-prepared organic fertilizer. Further, aims to produce a microbial inoculum for the composting process improvement.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"kc-elm kc-css-614051 kc_col-sm-6 kc_column kc_col-sm-6\">\n<div class=\"kc-col-container\">\n<div class=\"kc-elm kc-css-3445199 kc_text_block\">\n<h2>Objectives<\/h2>\n<ul>\n<li>1. Design a composting machine with the following specifications.<br \/>\u2022 Capacity: 2.5 kg<br \/>\u2022 Food waste volume reduction: by 80%<br \/>\u2022 Recyclable food waste types: All types of organic waste<br \/>\u2022 Process time: 24 hours<br \/>\u2022 Additive: Microbial inoculum<br \/>\u2022 Power consumption: 1 kWh\/cycle<br \/>\u2022 Automation: Fully automated<br \/>\u2022 Control: Control panel<\/p>\n<li>2. Achieve the following aspects to make the machine more reliable and usable.<br \/>\u2022 Energy-efficient as possible.<\/li>\n<p>\u2022 Low cost to make it affordable to the common people.<br \/>\u2022 User friendly, easy to operate, and require minimal maintenance.<br \/>\u2022 Portable so as to be easily movable at any place.<\/p>\n<li>3.
