Compost Science & Utilization Spring 2009 85 Introduction

Summary: Compost Science & Utilization Spring 2009 85
The production of municipal solid waste com-
post (MSWC) is an important recycling opportuni-
ty for many communities, however the safety of its
use in agriculture has been debated because of con-
cerns over the levels of its salt and metals content
(Hargreaves et al. 2008). Generally, MSWC will not
contain toxic levels of metals provided it is source
separated and sewage sludge has not been added
(Richard & Woodbury 1992; Zheljazkov & Warman
2004; Hargreaves et al. 2008). The production of
MSWC has been successful in reducing landfill ad-
ditions and has been economically and environ-
mentally sustainable for many communities (He et
al. 1992; Otten 2001). Expanding its usage to the
production of compost tea may further its value to
municipalities. Compost tea is an increasingly pop-
ular product in organic agriculture largely due to
testimonial support of its efficacy (Ryan et al. 2005).
