Separating our trash has become commonplace, with the frequently-used categories of paper, plastic, glass, and others. However, in Seoul, residents are required to separate their food waste as well (Figure 1 and Video 1)
Figure 1. The first time I was exposed to food separation and recycling policies was when I chanced upon an article from The Straits Times about a journalist’s culture shock over Seoul’s mandatory recycling and separating of food waste

Background of food waste in Seoul
Unknown to many, the South Korean government had actually started a series of policies to reduce food waste since 1997. During that period, the exponential rise of South Korea’s disposable income and standard of living, as one of the Asian Tigers, compounded by the culture of Korean meals to consist of at least five to seven side dishes, inevitably led to an increase in food waste. However, the initial implementation had seen a more than 20% reduction in food wastage (Chrobog, 2015). Over the years, the reduction of food waste has helped to reduce greenhouse gas (Nahman et al., 2012) and consequently, effects of food waste on climate change (Hartmann and Ahring, 2006).

The Good: Reducing the disconnectedness between consumers and their waste
The food waste policies in Seoul aided in reducing both the mental and physical distance of consumers and wastes. The act of collecting one’s food waste compel residents to be more conscious of how much waste they produce and hence, increasing accountability of their waste. This is evident by the annual reduction of food waste by 10% (Seoul Metropolitan Government, 2015). Furthermore, the physical distance of waste chains is diminished, with the separation and recycling done at home and in their neighbourhoods, instead of at the traditional transfer stations. Often, waste that is thrown ‘away’ naturally become ‘someone else’s’ responsibility – be it waste management companies, local municipalities or the government (Clapp, 2014: 4). Therefore, closing up this gap is important in reducing the disconnectedness and ignorance of consumers.
The Good: A useful guide for other cities
Seoul’s food waste management system can be a useful guide for other cities to adopt. For example, cities studied by other members of this blog, such as Singapore, is closely similar to Seoul in terms of being a high-density populated city. In Singapore, no such policy has been implemented and in 2016, only 14% of food waste was recycled (NEA, 2016). However, food waste recycling in Singapore is largely derived from industries and hence, this indicates a huge potential of increasing food waste recycling by implementing policies on a household level.
Additionally, Seoul’s food waste recycling and management system serves as a good example and particularly important for developing cities that are experiencing rapid urbanisation now (Lee and Jung, 2017). One of the notable reasons for Seoul’s success in food waste reduction was its advantage and foresight on starting early before the burden of food waste management became too straining on the cities’ budget and landfills. The administrative districts of Seoul shoulder about 70% of the total food waste disposal cost and as such, there was an incentive to reduce food waste because a reduction of food waste management cost would allow the city to channel budgets to providing other social infrastructure. For example, a reduction of annual food waste generated by as little as 20% (KRW 20-30billion of management cost would be saved), would be enough to build 30 public day-care centres (Seoul Metropolitan Government, 2015).
After learning more about the food waste management policies in Seoul, I feel that such solutions are less complicated than expected and see the benefits of normalising such practices to create a more sustainable world. Drawing parallels to how we, as Londoners, have adapted to using less plastic bags at supermarkets after the introduction of the 5p charge, I believe that while initial food waste separation policies may bring inconvenience, it is feasible to be integrated into people’s routines.
