Predictors of illegal dumping at charitable collection points

Abstract

Cleaning and disposal of illegal dumping at charitable collection points costs charities and diverts funds from their charitable programs. However, there is no published literature that attempts to better understand this problem. The current study assesses site-specific characteristics, community level indicators and sociodemographic factors as predictors of both charity stores and collection bin dumping in the metropolitan area of Perth, Australia. Multiple regression analyses revealed that higher levels of dumping at stores were predicted by being open on Sundays, the presence of gates/fencing, bringing bins in at night, greater 5-year mobility and lower levels of education and occupation in the area. The analysis also suggests that preventative measures have not necessarily been effective at reducing the amount of illegal dumping at stores. For charity bins, significant predictors of higher levels of dumping included private land ownership, if the site is shared with bins from another charity, the number of bins at the site, the number of days serviced per week, if the bin/s are located at a park/reserve and greater 5-year mobility. These results indicate that there is a combination of site-specific characteristics and community level indicators that play a role in illegal dumping at charitable collection points and indicate the type of interventions which may be successful in reducing illegal dumping. These may include improved maintenance, better placement of bins and signage and collaborations with real estate agents.
