Abstract
Process Economics Program Report No. 137
WASTE TREATMENT COSTS
(September 1980)
The past decade has seen the introduction of comprehensive
legislation by industrialized nations to control and reduce the
pollution of air, land, and water. Consequently, pollution abatement
costs to the chemical and related industries have risen sharply in real
terms since 1970. These costs are likely to continue to rise at least
until 1985.
The technology for pollution abatement Is generally the same as
that for mineral beneficiation and chemical production.
The application of SRI-developed modular capital and operating
costs to these operations provides a simple means to estimate waste
treatment costs for specific chemical plants.

September 1980
A private report by the
PROCESS ECONOMICS PROGRAM
Menlo Park, California 94025
For detailed marketing data and information, the reader is
referred to one of the SRI programs specializing in marketing
research. The CHEMICAL ECONOMICS HANDBOOK Program covers
most major chemicals and chemical products produced in the
United States and the WORLD PETROCHEMICALS Program covers
major hydrocarbons and their derivatives on a worldwide basis.
In addition, the SRI DIRECTORY OF CHEMICAL PRODUCERS services
provide detailed lists of chemical producers by company, prod-
uct, and plant for the United States and Western Europe.
