Handling the huge amount of solid waste generated by our ''throw-away
society'' is a major threat to a sustainable future. Recycling of used
products is one important contribution toward sustainability, and soc
ial science research can help to increase its success. Of the many var
ied forms of recycling, residential curbside recycling is fast becomin
g the dominant form in the U.S., but it has been little studied. This
article briefly reviews earlier research on other forms of recycling a
nd describes the findings of several recent studies of curbside progra
ms, including the new commingled collection method. In addition, it su
mmarizes a study on the growth of paper recycling by businesses, and a
study of consumers' environmentally conscious ''green buying,'' which
can help reduce the overall amount of solid waste that is generated.
