This article is a 1977 survey of US resource recovery and energy conservation practices. The number of operating resource recovery/thermal energy installations having an estimated capital investment of $500,000 or more were tallied in an attempt to separate voluntary action of citizens' groups from the larger, 'more sophisticated' efforts (i.e., those arbitrarily chosen with more than $500,000 in captial investments). A table is presented that lists the location and owner of facilities that have resource recovery and energy conservation features.
