This document summarizes a study on utilizing tannery waste from the leather industry in Tamil Nadu, India in concrete production. Tamil Nadu accounts for 70% of India's leather exports and the tannery industry produces significant waste. The study partially replaces fine aggregate in concrete with chrome dust, a byproduct from chrome tanning. The concrete production process and mix designs using chrome dust are described. Results showed the concrete with chrome dust has greater durability and strength while being more economical and environmentally friendly compared to traditional concrete.

3. ABSTRACT
TAMIL NADU IS THE MAJOR PRODUCER OF LEATHER GOODS AND HAS BEEN AN
IMPORTANT HUB FOR LEATHER INDUSTRIES . ACCORDING TO A SURVEY ,TAMIL NADU
ACCOUNTS FOR EXPORTS OF 70% OF THE ENTIRE LEATHER PROUDUTIONS IN INDIA .
THUS, TAMILNADU POLLUTION CONTROL BOARD [TNPCB] HAS EXECUTED AND ATTEMPTED
VARIOUS MEASURES FOR EFFICIENT REUSE AND EFFECTIVE METHODS OF DISPOSAL OF
WASTES . IN SPITE OF VARIOUS MEASURES AND STEPS TAKEN BY THE TNPCB ,FEW OF
THE WASTE P[RODUCTS ARE YET TO FIND ANY SORT OF DISPOSAL ARE RECYCLING
TECHNIQUIES .THUS AN ATTEMPT TO UTILIZE THE TANNERY WASTES IN THE FIELD OF
CONSTRUCTION CARRIED OUT.
