In vessel Organic waste composter is semi-automated/fully automatic composing machine. Organic materials are fed into a recycled plastic drum or similar equipment where the environmental conditions including temperature, moisture and aeration are closely controlled the appartments has a rotation mechanism for proper aeration.
In vessel Organic waste composter (In-V-OWC) provides quick, easy and cost effective option for larger quantity waste generated from townships, societies, Commercial places etc. In-vessel composting can process large amounts of organic waste in very limited area. In-vessel composting produces very little odour and minimal leachate because it works aerobically. Conversion of organic material into compost can take up to 25 to 30 days it depends upon the type of organic waste. The unit can efficiently trat organic waste resulting in volume reduction of upto 90% and convert the residual material into high quality compost can be used for horticulture / gardening in- vessel composters vary in size and capacity

Compost tumblers also called rotating drums are popular because they serve several purpose: blending, size reduction without shredding, and screening. Rather than turning the materials with a pitchfork, which can be labour intensive, users simply rotate the drum or turn a crank once or twice a day. Each rotation introduces more air into the system, and mixes the materials together. This increases the speed of the compost process.To harvest the finish compost, stop adding materials to the numbler to the tumbler and keep rotating it daily the compost is ready

this category of In-vessel systems uses a static composing method, i.e, there is no mechanical agitation while material is in the container or tunnel instead, agitation is provided when material is unbloaded.Fans supply oxygen and remove moisture and heat.
