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 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 highlighted, and more plans are increasingly
put in action to reduce food wastage.
Reasons for food waste differ 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 increasing 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 (Green Future Solutions, 2013; NEA, 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.
The 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, by the Singapore
government.
Firstly, food wastage results in detrimental environmental
effects. Proper treatment of food waste is a challenge as untreated food waste leads
not only to odor, but also issues of hygiene (Khoo, Lim, & Tan, 2009). Food
wastes are not sent to landfills as inorganic wastes 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
the environment quality which in turn affects people living around incinerators
(Franchini, Rial, Buiatti, & Bianchi, 2004). In an effort to reduce the
impactof 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 individuals in 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
produce. 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) Leftover food should be given to food banks and charities instead
of disposing off 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 by individuals at a
business or personal level 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 for the government to
carry out to increase 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 all individuals 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).
