We’ve been digging into some waste management data after hearing about a Houston-based group doing some interesting things. More on that later. GreenBiz points us to research out of Australia that posits a different way of looking at waste streams. From the abstract:
“Currently, cities use their waste diversion rate as a tool to measure the performance of their waste management systems. However, diversion of waste from landfill does not give a holistic picture of zero waste performance. This paper conceptualises the concept of the ‘zero waste city’ and proposes a new tool to measure the performance of waste management systems called the ‘zero waste index’. The zero waste index forecasts the amount of virgin materials, energy, water and greenhouse gas emissions substituted by the resources that are recovered from waste streams.”
The GreenBiz piece captured perhaps the most important point.
“The researchers disagree with the commonly held belief that zero end disposal through landfill is the same thing as zero waste, and argue that this definition does not place enough emphasis on how waste can be reused as a material resource (as opposed to being incinerated, for instance).
And here’s a look at the researchers’ view of the Zero Waste City.
