Performance Evaluation of Rotary Drum Composter

The study is carried out by composting of vegetable waste, cow dung and dry leaves in rotary drum composter. All the waste materials are mixed in appropriate proportions respectively for each trial. To study the effect of bulking agent two different ratios of waste combinations was employed i.e. (5:4:1) and (5:4:2). Rotary drum composter of capacity 210 l has been used and it is fed with 55 kg total weight keeping into view that human can turn it easily. The study was carried out using different turning frequency namely 12 h, 24 h and 48 h respectively. Parameters like TOC, moisture content/N ratio decreases at end of composting process i.e. 21 days. It is concluded that trial with 5:4:2 ratio followed by turning frequency of 48 h provided best results with C/N ratio 11.47.
