Résumé : |
The continuing trend of environmental regulation may soon make it impossible,legally or economically, to dispose of large quantities of tannery offals and wastes at private or municipal dump sites. Of particular concern will be those wastes containing chrome, including trim and shavings. An alternative process which could significantly reduce tannery solid wastes, could enhance the value of tannery offals, and also lead to improvements in process technology is discussed in economic terms. |
