Automatic Drum composting plant installed by DDA is designed to efficiently treat all kinds of Organic & Horticulture waste. Plant involves a high-speed shredder that breaks the waste down into small size for easy decomposition. This is then loaded manually into the composter. The composter starts the process by slowly rotating the material inside in a closed vessel. Lifters inside the drum help move the material as it rotates. A fan introduces oxygen in the composter for the composting process. Operation of the machine is controlled by a PLC (Programmer logic controller) for easy and automatic operation.

The naturally occurring aerobic bacteria do the actual decomposition work, and the composting drum provides the perfect setting by controlling all the relevant factors—moisture, oxygen, temperature—within the specific parameters that good composting requires as per Mother Nature!

The time that the waste remains in the vessel is called retention time and this can vary depending on the type of waste to be composted.

Typically, 12-14 days is sufficient to achieve compost that is about 95% mature (decomposed) and pathogen free, weed seed free, insect larvae free and virtually odorless.
