Students at the School of Engineering, RMIT University recently published a study experimenting with a new form of waste management and recycling. As they note in their research, cigarette butts are the most commonly discarded single waste item in the world, with an estimated 5.7 trillion having been consumed around the globe in 2016. However, the materials in cigarette butts—particularly their cellulose acetate filters—can be extremely harmful to the environment due to poor biodegradability. The RMIT study builds on a previous research study by Mohajerani et. al (2016) that experimented with adding discarded cigarette butts to clay bricks for architectural use. In their research, the RMIT students found that such a measure would reduce the energy consumption of the brick production process and lower the thermal conductivity of the bricks, but that other issues including bacterial contamination would have to be addressed prior to successful implementation. Below, we explore this research in more detail, investigating its relevance to the architecture industry and imagining possible futures of application.

Ethical practice spans all parts of architecture. From intersectionality and labor to the climate crisis, a designer must work with a range of conditions and contexts that inform the built environment and the process of its creation. Across cultures, policies and climates, architecture is as much functional and aesthetic as it is political, social, economic, and ecological. By addressing the ethics of practice, designers can reimagine the discipline's impact and who it serves.

Kiribati has a population of around 110,000 people and its economy is centered on fishing and agriculture. Comprised of 33 islands in the Central Pacific, its highest point is only 81 meters above sea level, which makes it potentially the first country that could disappear completely due to global warming and the consequent rise in sea levels. The climate crisis has been a hotly debated topic in recent years and terms such as carbon footprint, greenhouse effect, atmospheric aerosols, and many others, are already staples in our vocabulary. Another widely spoken term is “net zero”, or net zero emission, used as a goal for buildings in different industries and countries. Basically, it means that the energy balance is zero.
