Disposal of Wastes Generated

Sulfuric acid plants and downstream units generate certain wastes as follows these are difficult to reuse/dispose of  

Waste catalyst—especially with low residual vanadium pentoxide content. 

Spent scrubbing liquor containing a mixture of dilute solutions of sodium sulfite and sulfate. 

Dilute acid contanfinated with various organics, other impurities, etc. 

Disposal of waste liquors containing sulfates of iron, sodium, etc.

Recommendation 4a. The closure plan must include a consideration of storage, handling, and ultimate disposal of wastes generated from JACADS closure, including provisions for temporary staging and transportation on-site and off-site. 

This should also be everybody s concern ETP. Precautions shall be taken for plant design, operation and maintenance to minimise generation of wastes, recycle of effluents (if possible), and treatment of effluents. Disposal of wastes generated during plant operations can be done through suitable paths for disposal of incineration, secured land fiU, etc. 

This chapter describes options for the treatment and disposal of waste generated from the initial response actions. It also briefly describes some of the treatment or disposal options for long-term response. 

In order to provide a liaison channel between researchers in the field of pollution prevention and potential implementors of new and improved pollution prevention techniques, the EPA has joined with the University of Cincinnati in establishing the Waste Reduction Institute for Scientists and Engineers (WRISE). This new channel is important because of the unique nature of EPA s pollution prevention program and because EPA s ultimate clientele for this research are, to a large part, individuals in industry with whom EPA, traditionally, has not directly dealt, i.e., those people concerned with the processes that generate pollutants as opposed to those people who are concerned with the treatment and disposal of wastes. 

Preservation of a habitable planet demands that we minimize waste production and responsibly dispose of waste that is generated (Box 2-1). Recycling of chemicals is practiced in industry for economic as well as ethical reasons it should be an important component of pollution control in your lab.
