Do
you know that food is a major part of the waste material thrown out every day?
Rotten
or surplus food that is of no use is usually thrown out and goes into trash.
The amount of food that is thrown out every day is enormous.
Every
year, almost one third of the total food produced in the world for human use is
wasted (approximately 1.3 billion tonnes).
It
is estimated that a usual household throws away about 474 pounds of food waste
each year. In Canada and US 40% of food supply is wasted per annum. In New
Zealand, 122,547 tonnes of food is thrown out per year.
Global
quantitative food losses and waste per year are roughly 30 per cent for
cereals, 40-50 per cent for root crops, fruits and vegetables, 20 per cent for
oil seeds, meat and dairy plus 35 per cent for fish.
Seeing
the above horrendous facts and figures shouldn’t we have to know about the need
of composting food waste?
Food waste includes;
·
Vegetables
·
Cereals,
·
Fruits,
·
Bread,
·
Meat,
·
Dairy products,
·
Tea bags,
·
Grains,
·
General leftovers from
fridge.
All
this food goes in to waste and is of no use. This food waste can be used
effectively by composting.
Composting
is an environmental friendly technique and it converts our food waste into
useful product.
What is composting?
Composting is a natural way of recycling things.
In composting, organic waste that includes food waste, manure, leaves, grass
trimmings, paper, wood, feathers, crop residue etc. is biodegraded and
converted into a valuable organic fertilizer.
“Compost” is the product that is obtained as a
result of composting. Composting is a biological process which done
aerobically, i.e. in the presence of oxygen. Various microbes e.g. bacteria,
fungi convert organic matter into compost.
This compost works as a great fertilizer for
plants. There is a dire need to know about composting of food waste. Bacteria
mainly need water, air, carbon and nitrogen for composting.
Composting at home is safer
Food
waste is excellent for composting. Home composting of food scraps produces
five times less greenhouse gases than the industrial composting.
These
food scraps would otherwise go to waste bins and water streams and ultimately
create solid waste problem.
So,
composting is a way to treat food waste and convert it into a useful product.
It avoids the going of food waste into landfills and recovery plants. Most
importantly, it is an environmental friendly process and no harmful by-products
would be produced from it.
Where to do food composting?
Composting
of food waste can be done either at home or commercially. In landfills, food
composting is not advisable as toxic waste materials are added to the food
waste. The recyclable materials in landfill would mix up and cannot be used
again.
Another
drawback is that the huge piles of waste one onto other deprive lower layers
from oxygen. It is recommended to compost food waste at home. This is not a cumbersome
process and fertilizer for home garden or plants can easily be made from it. It
requires less time and little efforts.
Does all kind of food waste should be composted?
Not
all the food waste should be composted. There are certain food wastes that are
not good to be composted e.g. large amount of meat should not be composted
because it will attract large amount of insects and its smell is also very bad.
Other
foods that are not suitable for composting are oil products, dairy products
(butter, cheese) fish. Vegetables, fruits, coffee, grains etc. are good for
composting.
Composting food waste at home
Food
waste at home can either be composted indoor
or outdoor. Outdoor composting
can be done in the backyard, lawn etc. Indoor composting can be done inside the
house in special type of composting bins.
7 easy steps for composting food waste
A
properly managed compost bin will not attract pests or rodents and will not
smell bad. Such bins are easily available in the market. You can also buy them
online.
Following
are the key steps to do composting at home:
1. Take
a composting bin made of wood and make some holes in it with the help of a
drill
2. Separate
food waste from your non-food household waste like metals, used papers, dust
etc
3. Collect
some dry organic matter also like dry leaves, straw etc. Moisten this dry
material.
4. Now
fill the container with soil. Then add alternate layers of food waste and dry
organic waste.
5. At
the end cover this container with plastic sheet and do not close it air tightly
to allow air passage.
7. This
compost can be used as a natural fertilizer.
Besides
this conventional composting, there is also another type of composting known as
worm composting.
In
worm composting worms are used to biodegrade food waste. Worm composting can
also be done at home by adding worms to the composting bin.
10 benefits of composting food waste
1. Soil
would be enriched with nutrients and best for growth of plants.
2. By
food waste composting, the amount of food waste that goes to landfill would be
decreased
3. Compost
helps water retention in soil
4. Returns
food waste to agricultural soil
5. Clear
landfills space by removing food scraps from landfill
6. Help
form low cost fertilizer at home
7. Lessen
the need for chemical fertilizer as this natural fertilizer would work
8. Promotes
carbon sequestration and lowers carbon foot print
9. Lessen
the release of methane gas from landfills
1. Helps
in restoring the recycling material by avoiding their mixture with food and
ending up in soil having no use.
So
this is all you need to know about composting food waste at home. This is the
easiest way to avoid adding more solid waste on our already degraded land.
