The EI Digest annual reports covering the commercial hazardous waste landfill market began in 1990. At which time about 20 commercial hazardous waste landfills participated in our research efforts. The 20 landfills represented less than full participation by the commercial hazardous waste landfills operating in Canada and the United States in 1990. Tonnages accepted at some of the hazardous waste landfills that were operating at that time, but did participate, have remained unknown despite our efforts to obtain them.

By 1993, the EI Digest research had greater cooperation with its annual research reports. However, in the interim, there had been some closures of commercial hazardous waste landfills, notably Browning Ferris Industries had exited the commercial hazardous waste services. At that time, BFI was the second largest solid waste company in the United States. The 20 commercial hazardous waste landfills participated in the 1993 survey represented almost all the commercial hazardous waste landfills operating at that time. Our research efforts determined there to be approximately 3.5 million tons of waste accepted at the 20 commercial hazardous waste landfills.

During the 1990s, commercial hazardous waste landfills took more "total" waste (combined hazardous and nonhazardous waste) and more hazardous waste than any other individual commercial hazardous waste management sector. However, it did not experience the same type of growth as did sector like incineration which experienced a 400% increase. But, it benefited more than any other sector from waste from event sources just it does today. Consequently, the historical records of disposal at individual commercial hazardous waste landfills has an irregular trends caused by year to year differences in the amount of event waste.

In 1997, the research efforts started requesting commercial hazardous waste landfills differentiate between the amount of nonhazardous and hazardous waste accepted each year. It then became more obvious that some commercial hazardous waste landfills had been previous reporting "total" waste (both hazardous and nonhazardous waste) accepted while others had been reporting only federal hazardous waste. The survey efforts were also changed in 1997 to request the amount of waste coming from event (remediation) sources and those coming from base sources (e.g. process waste from manufacturing).

This report will first review the market situation in 2010 with respect to both hazardous and nonhazardous waste acceptance. The report will then examine the 2010 demand compared to the demand in the immediately preceding year (2009) and thereafter to trends over the last decade. Subsequently the report examines the results derived from biennial reporting by generators between 2001 and 2009 in an effort to derive some further understanding of grass roots level trends with base sources.
