Municipal composting schemes: international case studies

11 Nov 2016

This report contains summaries of international examples of kerbside collection of compostables in urban environments. It was prepared as part of the CRC for Low Carbon Living project: Carbon reductions from composting food waste for food production – fitting recycling models to urban form.
A diverse range of cities has been included to illustrate different strategies for implementation and for engaging citizens. The reasons these cities have undertaken kerbside food scrap collection andcomposting programs include landfill closure, environmental consciousness and cost savings. The cities compiled in this report were chosen and investigated through desktop internet research and each promotes source separation of compostable waste. In most cases the compostables are taken for off-site composting, but in several cases, this is preceded by anaerobic digestion. Although the focus is on cities in industrialised countries, several towns have been included as well as three cases from Asia and South America, in order to illustrate particular unique aspects.
In order to facilitate browsing, and to allow the reader quick access to relevant information, the summary for each city is structured using the following headings:

Publicity, information and education
Policy/legislative changes contributing to success

The report is designed to give an overview of, and introduction to, a range of food scrap collection/composting schemes. References and contact details for more information on each case are provided at the end of the report.
