Hi Kit, thank you for a thought-provoking article. I agree that waste disposal might at first seem like a mundane subject but that its importance in urban design is paramount, just imagine what our cities would be like without effective waste disposal!
In the 21st Century, recycling has become the cornerstone of effective waste disposal, as it helps to limit our use of natural resources, and frees up space in landfill which in turn benefits the environment and biodiversity. Whilst I agree urban designers need to look at fun and innovative ways to encourage people to recycle more, I feel there is a bigger issue here, that of using landfill at all. Landfill sites are clearly an unsustainable solution to processing waste which cannot be recycled, and I wonder if there is an alternative to using them?
One alternative is Waste to Energy (WTE) incineration, which uses waste as a fuel in order to create energy. In the face of rising energy prices and our continued reliance on fossil fuels, this seems like a practical solution, however the process releases additional greenhouse gases in the form of CO2 which are comparable to that produced when creating energy from coal.
Another approach is the process of anaerobic digestion, by which bacteria and other microorganisms break down organic waste without the need for oxygen and open air. It is seen as a renewable energy process, which uses waste to create methane, which can then be used as an energy source.
Perhaps the simplest and most environmentally friendly solution is composting, a process that allows biological waste to break down naturally. Composting allows for organic waste to be recycled rapidly, and to be turned into fertiliser which can be used in farming. The fact that composting can also be used to process human waste opens up the opportunity to radically reevaluate waste management systems in urban designs.
Once again, we find that often the simplest solutions are the ones grounded in natural systems. Homes with inbuilt composting systems which turn food or human waste into fertiliser, or which are able to heat water and generate methane for domestic use, could transform our domestic waste output and challenge our overreliance on fossil fuels.
