disposal is becoming a growing concern in many
countries, particularly where population is increasing
in areas with lesser living space. It is quite
astonishing to see the amount of garbage and waste we
can generate in a day, and the grave impact it can have
on our environment, when its disposal is not handled in
the correct way. Although, most places have an effective
system of collecting garbage from homes, this garbage is
ultimately going to end up in a landfill that is going
to pollute the environment over decades. The best way of
handling this situation is to reduce the amount of food
waste that ends up in your dustbin. When you reduce the
level of trash in your garbage bins, you also save quite
a bit on fees that you might be paying per garbage bag.
Hence, for saving money and helping your environment,
the best solution is to install a refuse disposal unit
in your kitchen, which will effectively dispose food
waste. This appliance is usually connected to the sink
drain in the kitchen, and is installed under the sink.
Refuse disposal is either placing waste in water or onto land. This is done depending on the type of waste, either solid or liquid waste. Solid waste is disposed by placing it on land in a landfill, while liquid waste is disposed by injecting it in wells that burry the effluent deep under the ground. As mentioned earlier, there are many systems in place for proper waste management. Here are some few refuse disposal methods that can help bring waste disposal under control. Before using any method, it is important for any industry to evaluate and determine the most important criteria for their refuse disposal.
Description of Refuse Disposal Appliance
The refuse disposal appliance is used to pulverize food
waste so that it is converted into a thick liquid form,
and gets disposed off in the regular sewer system or
into a septic tank. The upper section of the appliance
has a hopper chamber that stores the food waste. The
appliance is equipped with a powerful motor, which is
used to spin a shredder ring at a high RPM. The spinning
throws the food waste against this shredder and it gets
ground and pulverized. The water from the sink faucet
will flush the pulverized waste through the discharge
outlet, and into the sewer or septic system.
Types of Refuse Disposal Appliances
Refuse disposal units are mainly categorized into
continuous feed and batch feed types. In the continuous
feed appliance, the system turns on the grinding
mechanism automatically, whenever any waste slides down
the drain. This is quite convenient, as you do not need
to turn on the appliance manually, whenever you want to
dispose food waste. However, it can be unsafe when you
have young children in the house. The batch feed refuse
disposal system on the other hand is quite safe, as you
have to plug in and turn on the appliance manually, and
the switch can be kept where kids cannot reach it. Here
you have to first load the appliance with the food waste
through the sink drain, and then turn it on, for
Considering the Design and Power Capacity of Refuse
The design of a refuse disposal unit should be compact
enough to fit in the available area under your sink.
Most models have a compact design; however, you should
know that smaller models would usually have lesser
power. The power capacity is in terms of HP of the
motor, and a 3/4 HP motor is usually quite sufficient.
Smaller sized models will have 1/4 to 1/2 HP motors, and
large disposal units can have up to 1HP power.
Food waste will usually consist of vegetable skins,
poultry or meat bones, and corncobs. Although bones and
cobs are quite tough they do not pose a problem even for
a 1/2 HP motor. However, waste of stringy vegetables is
what usually causes the problems. This waste can be
ground easily, but it can often clog your drain. Hence,
look for units that have a multi-stage system that will
produce more liquefied waste. Having noise reduction and
anti-jamming features are also an added advantage.
Refuse Disposal Appliances for Septic Systems
Most of the refuse disposal appliances will advertise
that they are safe to be used with a septic system.
However, it is best to select models that are specially
made for septic systems, as they will be dispensing a
formulated solution of microorganisms, which help in
maintaining septic tanks. These microorganisms help in
breaking down the waste much faster, and even if the
tank is not built for additional load, it will reduce
the frequency of emptying and cleaning the septic tank.
Durability and Maintenance
Refuse disposal units, manufactured by popular companies
are quite durable. However, look for models having
grinding parts and blades made of stainless steel, and
having a multi-stage system. Maintenance is minimal, and
only the models for septic systems will need a refill of
the microorganism solution. The only problem often faced
is that of clogging, and you might have to call a
plumber to clear the drain, if the clog is stubborn.
Most of the popular brands offer lifetime warranties for
the appliance, and some even extend home service
General Tips for Using Refuse Disposal Appliances
Always let some extra water flow, before and after the
food waste has been pulverized. This way, the drain will
be cleared, and the blades will give an optimal
performance. If you do not run adequate water, food
waste can be trapped inside the unit and start rotting,
which can create quite a stink.
It is better to run cold water instead of hot, as fats
in the food waste can melt, and again become solid as
they travel further down the drain. This can create
messy blockages in your pipes, whereas cold water will
not let the fat melt, and it will be pulverized in the
Do not use harsh chemical like drain cleaners or
bleaches for cleaning the sink. These substances are
highly corrosive and can damage the blades and grinding
mechanism in your refuse disposal unit. If you are using
a septic tank then these chemicals will wipe out the
microorganisms that are needed to break down the waste.
Refuse disposal systems convert many type of solid food
wastes into a liquefied form that can be easily drained
into sewer or septic systems. This is the most efficient
way of disposing garbage, as it reduces any harmful
effects on the environment. Refuse disposal appliances
are quite reasonably priced, and every homeowner should
think of installing them in their kitchen.
