Abstract:

According to European legislation, it is not possible to dump any chromium-containing waste in Europe. The minimization of wastes is a key element in that strategy. It involves the application of clean technologies: low and non-waste technologies. The tanning industry generates substantial quantities of chromium-containing solid waste in the form of shavings and trimmings. The recycling and reuse of those wastes must be the primary target in optimizing processes of the leather industry. The problem is in a satisfying chromium separation from collagen fibers. Common hydrolysis processes-alkalin

Abstract:

Waste minimization opportunities could be of great importance for decreasing the waste pollution load and production costs. A formulation of multi-objective optimization problems is proposed for the optimal design of chemical processes with waste minimization. As an illustrating example, a problem of optimal design of multipurpose chemical processes was solved. The approach developed is shown to be effective for solving problems of optimal design of chemical processes with waste minimization.

Abstract:

Pollution prevention, often referred to as source reduction, encompasses all activities that lead to reductions in the amount and/or toxicity of wastes. Waste minimization, on the other hand, refers to all activities including source reduction, on-site reuse, and recycling that lead to reductions in the amount and/or toxicity of waste generated, stored, treated, or disposed of by a given facility. Pollution prevention generally is regarded as the most cost-effective component of integrated waste management strategies. This paper describes an industrial pollution prevention program at an aging

Abstract:

Supplying the growing demands of society for goods and services is leading to a depletion of resources and an increase in the amount of waste generated. The uniqueness of the chemical industry requires special solutions. Waste management and waste minimization, including recycling, reuse, and valorization, must become integral parts of any production process or facility. Examples are given at the single process level, at the product group level, and at the production facility level of successful programs that eliminated or signifantly reduced the amount of waste generated.

Abstract:

Ever-tightening regulations on releases to the environment have become a major business factor for the chemical industry. The Organic Chemicals, Plastics, and Synthetic Fibers (OCPSF) effluent guidelines have required many manufacturing sites to expand or upgrade their wastewater treatment plants (WWTP) at considerable cost. Du Pont has recognized the need to shift the emphasis from “end-of-pipe” treatment to waste reduction and elimination at the process source.

Abstract:

Selection of cutting and washing fluids as a method of waste minimization The results of the corrosion test for washing and cutting fluids used in the process of gear-shafts production are presented. The test has been performed according to the DIN 51360-2 (Ford-test) and the PN-92/M-55789 procedures. Three cutting fluids and three washing fluids were chosen and their solutions in tap water (used in practice in the company) were investigated. On the basis of the obtained results it has been stated that the lower the fluid concentration, the stronger corrosion is developed. The concentrations r

Abstract:

The interaction between two or more independent causes of materials degradation results in a duplex mode of materials degradation. The materials degradation rate whether expressed in loss of material or loss of mechanical strength is often faster than the sum of each form of materials degradation acting separately. For this reason, duplex modes of materials degradation are of great practical importance. Synergisms between unrelated forms of materials degradation are not immediately obvious and have in some instances been only recently recognized. In this paper a chemically aggressive environme
