Domestic Plastic -- Plastic Domestic

Thesis Supervisor: A/P Ong Ker Shing

This thesis begins with the examination on Singapore’s Semakau Landfill crisis. With the current speed, it will be filled up before 2035, which is much sooner than expected. With the understanding that Singapore is implementing Waste-to-Energy method (Combustion) to turn waste into energy before burying the ashes in Semakau island, the thesis questions the effectiveness of combustion as a solution to waste problem and claims that reducing consumption is the key to the issue. Moreover, most people are not aware of the amount of waste they have disposed because the government has been taking care of everyone’s trash. Therefore, the project proposes a strategy to spatialize waste and bring individual’s waste into their own domestics. Plastic waste is the focus of this project because of the difficulty in its recycling as well as its harm to our environment.


The thesis thus proposes a new waste system such that people will get back their plastic waste as plastic blocks by monthly basis. The state will absorb 3 plastic blocks for each resident every month, and if a resident

generates more plastic waste than this amount, he or she will get back the plastics as plastic blocks.


The system bears two aims:

1.   Allow housing to function as a plastic basin to slow down the accumulation of plastic waste in landfill.

2.  To increase the awareness of how much plastic waste each individual has generated and thus induce a change in people’s plastic consumption habits.


By investigating the accumulation of plastic blocks in one’s house, the thesis also explores the plasticity in our current domestic space. Different family characteristics are shown in the customization of interior, not through furniture, but modification of volume. The new domestic space changes with time, reflecting one’s living habits and uniqueness. This thus also brings up a new perspective of domestic space, which could be designed through volume, instead of homogenous compartmentation walls and dividing spaces.

The new system breaks the huge plastic issue into many small problems, letting individuals be responsible to the plastic waste they have disposed, targeting at domestic scale. Part of plastic waste will be absorbed by landfill as usual while the rest will be sent back to each household as a form of plastic blocks.

Image 1: Under the facet of annoyance, there are mainly 7 considerations when residents stacking plastic blocks in their home, each household has different priorities. People ‘s creativity and genius reshape the volume of their home.

As families recieve more plastic blocks, their way of storing plastic blocks changed as their family evolved with time. People used these plastic blocks to create new walls floors and walls, reshaping their home. After 15 years, what can be observed is not only people’s tolerance of space, but also the customization of the interior, not through furniture, but the modification in volumes.

Despite of expected culture and behaviours in certain rooms at home, each household still bears very different characteristics and living habits. Every family has their own domestic volumes that display the uniqueness of every family. The residents demonstrate the plasticity of domestic unit as an outcome of an individual’s creativity in the facet of annoyance.
