According to
the Food and Agriculture
Organization of the United Nations (2014), food
waste refers to "intentional discards of edible items, and is mainly due to
behavior of businesses and individuals”.
Annually, global food waste amounts to 1.2 billion metric tons, and
about one-third of the production of food for human consumption is wasted
(Venkat, 2012). Food waste is becoming a
significant issue especially in countries of major economies as food demand
increases.
As Ian Goldin mentioned in his TED talk, “The collapse in
biodiversity, climate change, pandemics, financial crisis will be currency that
we will think about. New awareness will have to arise, of how we deal with it,
mobilize ourselves, and come together as a community to manage systemic risk.”
The impact of food waste on our environment creates not only an economic crisis,
but also a climate risk that should be dealt with swiftly. In recent years,
awareness of this issue has been brought up, and more plans are increasingly
put in action to reduce wastage figures.
Reasons for food waste differs among
countries (Venkat, 2012). According to the National Environmental Agency (NEA)
of Singapore, increasing rates of food waste can be attributed to “population
growth as well as increases in tourist arrivals, and increase affluence” (Green
Future Solutions, 2013). The total food waste output in Singapore in 2012 was
703, 200 tons, generating 26 percent more food waste compared to 2007 where
total waste output was 558, 900 tons (NEA, 2013; Green Future Solutions, 2013).
According to Green Future Solutions (2013), food wastage in Singapore comes
from all areas of its supply chain; from
the production, to cosmetic filtering for sale, business and cultural
practices, and lastly, personal consumption at home.
Thus, this article discusses how food wastage in Singapore has become increasingly prevalent from all
links of its supply chain due to the ease of food accessibility, leading to a
need for more practical treatment
measures of food waste as well as enhanced
public education on food recycling.
Firstly,
food wastage results in detrimental environmental effects. Proper treatment of
food waste is a challenge as untreated food waste would lead not only to odor,
but also issues of hygiene (Khoo, Lim, & Tan, 2009). Food wastes are not
sent to landfills as inorganic waste are, but rather they are treated by
incinerators. Incineration produces volatile greenhouse gaseous emissions
including methane, nitrogen dioxide, sulphur dioxide, and carbon monoxide that
compromises not only the environment quality that in turn affects people living
around incinerators (Franchini, Rial, Buiatti, & Bianchi, 2004). As an effort to reduce impacts caused by
incinerating food waste, anaerobic digestion and composting is carried out.
According to Khoo, Lim, & Tan (2009), this is an effort to recycle food
waste. Instead of volatile gaseous emissions, it produces a by-product of
bio-gas that is “transferred into gas engines to generate electrical energy
which is then sold to National grid”. Anaerobic digestion and composting is
evidently a better alternative to the environment, as energy can be put to
greater purposes.
Secondly,
food wastage results in financial and social impacts. Food prices are
increasing, resulting in a wider unequal food distribution when food wasted
could be given to the poor and malnourished around the world. As a solution to
this problem, more efforts should be put into educating all areas of the supply
chain about food wastage. According to Green Future Solutions (2013), there are
3 tips that could apply to businesses as well as individuals to “reduce,
redistribute, and recycle” food waste: (1) “Grow and Buy”, (2) “Cook and Eat”,
(3) “Give and Recycle”.
For businesses pertaining to the above 3 tips: (1) Businesses
could contribute to our local economy by supporting and buying from agriculture
growth. Also, proper management of food policies should be carried out, e.g.,
by accepting “cosmetically imperfect food”. (2) Kitchen habits and methods
should be improved, e.g., ensuring proper food storage to avoid excessive spoilage.
(3) Giving leftover food to food banks and charities instead of disposing of
them (Green Future Solutions, 2013).
For individuals: (1) Individuals could grow their
own food, and plan a grocery list beforehand. This will ensure that they purchase
necessary food products sufficient for their household. (2) Individuals should
have knowledge of proper storage techniques to avoid disposal of food due to spoilage.
(3) Activities like food composting can also be carried out at a home level.
Garbage enzyme process is also a possible alternative, providing a wholesome effect
of recycling food into usable products (Green Future Solutions, 2013). It is clear that many steps can be
taken to avoid wastage of food that is perfectly fine to be consumed. Education
of public for these steps to be put to good use is thus a worthy solution to
increasing the recycling of food.
In conclusion,
food wastage in Singapore has become
increasingly prevalent, leading to environmental, financial, and social impacts
on our society. However, it is possible for individuals of all levels to play a part in
reducing food wastage. Preventing food waste will not only ensure a better
environment for our future, but also help to increase food availability and
strengthen food security for future generations (Green Future Solutions,
2013).
