As the amount of material diverted through recycling or BCDL increases, average cost of disposal can increase.
Results for recycling were then adjusted for the case of a concurrent BCDL system.
The Tellus model credits an avoided cost to recycling and BCDL of the average solid waste management fee ($50/ton in the base case).
If the full tip fee is credited to the BCDL system as an avoided cost, as the Tellus analysis does, this would have to be through payment by the community to the BCDL system (e.

The sensitivity (slope) of the recycling cost is higher for no BCDL, where net cost relies more on revenues than does the BCDL case.
Given the high cost of recycling through BCDL (more than $420/ton net of revenues), avoided cost of disposal (marginal cost saving) would have to exceed this figure, which is far from likely.
17) Because 19 percent of the MSW is potentially and readily available for household separation for recycling (Table 2),(18) a capture of 18 percent in a household recycling program would divert as much waste as BCDL.
Recycling and BCDL programs operating concurrently could divert more material than either alone if BCDL participation is about 85 percent and the recycling capture is greater than about 20 percent, which is far below expectation.
In neighborhoods with low participation or no recycling program, BCDL diverts more material from disposal.
Some literature cited on dual systems, especially GAO (1990), stressed that the municipality pays for curbside recycling but not for BCDL.
