How Australian cities can transition into zero waste Eco-Cities of the future

Tuesday, March 12, 2019

What is an Eco-City?

Imagine a city that efficiently provides for its inhabitants, without consuming more resources than it produces, without producing more waste than it can assimilate, and without being toxic to itself or neighbouring ecosystems.

Modern environmental, social and economic trends have been encouraging a new generation of town planners, governing bodies, and city residents to find even more innovative ways to live more sustainably. In all the conversations over the decades, food waste has been one of the least prevalent themes… until now. Eco-Cities are beginning to address where food is grown, and how/by whom it is grown, processed, imported, distributed and repurposed.

Eco-Cities and Waste

Each Eco-City has aspirations to provide manageable social hives that achieve zero waste. Ranging from organic waste, construction waste and everything in between, it implies that all waste is a resource. The need is to change the attitude and behaviour of residents and businesses to understand that waste is not unavoidable, but instead should be recovered and repurposed to help build and maintain a sustainable way of life. Here in Australia we are wasting around $8 billion worth of edible food each year, which raises the questions:

  1. Are we succeeding in changing people’s attitudes and behaviours around waste?    
  2. How do urban developers and residents get Eco-Cities to better engage with zero waste thinking?

Eco-Cities and Food Waste

Food waste considerations should now be playing an influential role in creating the zero waste Eco-City of the future. The usual issues of urban sprawl, unemployment and pollution are all still at the forefront, but with more people comes more waste. With ever-expanding cities and continuous population growth, urban developers and governing bodies need to begin by tackling food waste at source through the simple means of dehydration.

Eco Guardians’ SoilFood™ Systems are being specified throughout Australia to prevent truck movements, reduce GHG emissions and repurpose food waste into a valuable organic fertiliser. The process creates two outputs:

  • Clear, pathogen-free water that can be harvested for on-site grey-water applications or flow to sewer without any trade waste implications.    
  • A well qualified organic fertiliser that we call SoilFood ™, which is roughly 15% of the input volume. It is also pathogen free, safe to handle and stable. The use of SoilFood™ helps to regenerate Australian soils that have been devastated by over farming and heavy chemical use.  

Repurposing food waste into organic fertiliser for growing organic produce is one way in which city dwellers and governing bodies can connect with regional farmers. The addition of organic material to depleted soils is increasingly recognised as a vital and an urgent necessity. Eco Guardians SoilFood™Systems are an effective and efficient way to restore nutrients to cropping lands, creating the connection between Eco-Cities and Australian produce and culture.

Encouraging residents to change their attitudes towards waste and adopt the process of diverting their food waste from landfill will be a challenge. However, this diversion from landfill will benefit the land and reduce Greenhouse Gases, which are both social and environmental targets to transform communities into Eco-Cities with circular economies.
