Compostable organics represent 62% of all waste sent to landfill in Australia and
significantly contribute to the greenhouse gas emissions from the waste sector. With
the challenge of climate change and the scarcity of landfill space, the diversion and
recovery of the compostable organics waste stream is increasingly important. Food
organics is the dominant component of the compostable organics waste stream and
the major source of methane production in Australian landfills. However, the
national recovery level of food organics is only 10%.
This study examined food organics management amongst 23 businesses in
Hobart, Tasmania, Australia through a face-to-face survey in July and August 2010.
Information was obtained in order to: (1) determine the volume of organic material
generated; (2) examine the methods used to reduce and dispose food organics; and
(3) determine the barriers and opportunities for increased food organics diversion in
The study determined that measures to avoid the generation of food organics had
been implemented to a greater extent than measures for the recovery of food
organics. Food organics were mainly diverted by businesses within the
Manufacturing and Wholesaling and Food Retailing business group while limited
action was taken by businesses in the Accommodation and Food Services and
Educational and Health Institutions sectors. Donation of food organics for animal
feed was the recovery measure primarily used by businesses followed by donation of
surplus food to charity.
The barriers reported by businesses as impeding food organics separation for
recovery are primarily financial, including the increase of waste disposal costs and a
lack of economic incentive to participate in a separated food organics collection
service. The absence of a collection service for food organics and a lack of
information on alternative options available to divert food organics from landfill
were also reported as barriers to better organics management practices. The survey
determined that the majority of businesses are willing to divert food organics but
under the condition that it is economically beneficial or at least cost neutral.
