Subsidies for waste recycling
DEARSIR: Your May 1970 editorial, “Reusing resources easier said than done” (page 3 6 5 ) poses the problem of recycling and concludes that subsidies may be called for. Part of the reason that recycling is uneconomic is because of the present subsidies t o mining interests. I would think that, rather thsn push for more subsidies, you would champion the cause f o r elimination of subsidies that encourage present practices of using up the Earth’s natural resources. Certainly, the depletion allowance is foremost among the subsidies that suppress an efficient recycling of many minerals because it distorts the ecofiomics of recycling vs. mining. Apparently our society has entered re-
cycling in the Kentucky Derby, given it a handicap by attaching it t o a milkwagon, and then has bemoaned the fact that it seldom wins the race. A little “hurly-burly of the general marketplace” might be welcome f o r a change and might encourage recycling more than any amount of bemoaning. David R. Dawdy 1312 Morgan St. Fort Collins. Colo. Central waste disposal
DEARSIR: In your article concerning central waste disposal plants (ES&T, March 1970, page 195), you indicated that the Goodfellow plant near Sarnia. Ontario, is “not a particularly good
model for the pollution control service industry t o follow.” As the designers, builders, and technical managers of this plant, we feel that this must be defended. This plant is a pioneer effort a t solving a universal industry problem and it is a n economic and technical success. It is disposing of nearly 100,000 cubic yards per year of industrial wastes, and it is doing it in the Province of Ontario, which has the most qualified and best organized pollution control agency that we have seen anywhere in the U.S. or Canada. The plant is constantly being improved, and the installation being designed for the Toronto area will incorporate the considerable knowledge gained from the Sarnia plant operation.
