• “A process
in which compostable material is enclosed in a drum, silo,
bin, tunnel, reactor, or other container for the purpose of
producing compost, maintained under uniform conditions of
temperature and moisture where air-borne emissions are
controlled”
• Uses
forced aeration and/or mechanical agitation to control
conditions and promote rapid
composting
• Each
system design is different, but there are some common
elements.
Advantages
of In-Vessel Composting
• Composting
can be more closely controlled, leading to faster
decomposition and more Consistent product quality.
• Effects of
weather are diminished
• Less
manpower is required to operate the system and staff is less
exposed to composting material
• Can often
be done onsite, saving collection costs
• Less land
area is required
• Process
air and leachate can be more easily collected and treated
• Public
acceptance of facility may be better
• Can
accommodate various types and amounts of organic waste
(e.g., odorous bio solids & food)
Factors
responsible for composting
CARBON:
NITROGEN RATIO
Raw
materials blended to provide a C:N ratio of 25:1 to 30:1 are
ideal for active composting, although initial ratios of 20:1
up to 40:1 consistently give good results.
OXYGEN
Oxygen is
very important in composting because it enhances the growth
of aerobic bacteria. Aerobic bacteria are bacteria that grow
and live in the presence of oxygen and are very efficient in
breaking down waste.
TEMPERATURE
Microbial
decomposition during composting releases large amounts of
energy as heat, which raises the temperature. Composting is
most efficient when the temperature of the composting
material is between 55-60 degree Centigrade . Composting
stops if the compost becomes too cold or too hot. Hence the
temperature to be monitored.
MOISTURE
Moisture is
the lifeblood of the metabolic processes of the microbes.
Water provides the medium for chemical reactions, transport
nutrients and allows the microorganisms to move from place
to place. Efficient activity is achieved when the moisture
is maintained between 40% and 60%. More the surface area,
the faster the decomposition and the more usable compost
BIOCHEST
The
BIOCHEST
(Organic waste Composting reactor) converts your biodegradable
waste into compost (fertilizer) automatically.
BIOCHEST
was developed after extensive research and development work
conducted at our premises in Chennai, India.
BIOCHEST
Uses forced aeration and mechanical agitation to control conditions
and promote rapid composting. The
BIOCHEST
is a
combination of a device and process, targeting the quickest
transformation of biological; waste into consistent -
quality compost at the lowest possible cost and management
effort. With the
BIOCHEST
you are ahead of the rest ready to meet any stringent environmental
standards that may restrict operations from using
traditional disposal methods. With
BIOCHEST you will be
able to transform your biological and organic wastes into a
value added product to your operation and in turn recover
some or all of its capital investment.
Salient features of
Biochest compared to other systems
Disadvantages in other Machines |
Advantages in
BIOCHEST |
No time, microbes and
oxygen (air) provided in this system - So it is
not a composting system |
We are adding microbes, providing aeration
through blowers and providing enough time for
the microbes to do their work. In our reactor we
are providing all the required biotic and
abiotic factors required for the microbes to
work. |
Depends on the heating element |
No heating element, The Microbes present,
themselves will produce the heat required
naturally |
Just charring the waste into black
colored char by heating |
Waste are not charred artificially, they are
composted
by the microbes naturally by the process of
aerobic
composting |
No nutrient value in the
charred material |
Very high nutrient value, with more amount of
readily
available nitrogen for plants |
Power intensive, has it needs enormous
heating load |
Less power intensive, as there is no heating
element |
Cannot be used as a fertilizer |
Can be used as High quality organic fertilizer |
It’s is not a composting reactor, just
a mixer. As per the international composting
councils the temperature should be maintained
50-60 degree centigrade by removing excess heat
by circulating the air inside instead it is
fried at more than 100 degree centigrade. |
Biochest is a composting reactor.
We are adding microbes, providing aeration
through blowers and providing enough time for
the microbes to do their work. In our reactor we
are providing all the required biotic and
abiotic factors required for the microbes to
work (Composting). |
Needs larger area for curing |
No large area needed, only limited space needed
for storage bins |
No provision provided to control odour
and obnoxious gases produced during composting
or mixing process |
Our reactor has an inbuilt Biofilter, which
removes all
the odour and scrubs the obnoxious gases
produced
during composting or mixing process. Our
system is Odour free |
Dangerous gases like SO2 are not
scrubbed, will lead to health issue |
The biofilter will scrub all the obnoxious gases
like
SO2 produced during the composting process. And
releases only the odour free gases out |

we
suggest organic shredder to be used with machines of
100kg/day capacity or more for better composting.
