<p>Waste management plays a vital role in the reuse of industry wastes in to useful conversions. The treatment of effluents from the combined textile effluent treatment plant and hypo sludge from the paper industry results in sludge generation which poses a huge challenge for its disposal. Therefore, an eco friendly attempt is made to utilize them in the production of paver blocks. Paver blocks are a construction unit which imparts vast application in street roads, walking paths, fuel stations etc. In this study, an innovative attempt has been made to manufacture paver blocks incorporated with textile effluent treatment plant sludge and hypo sludge to utilize them with suitable proportions. The effect of adding silica fume and polypropylene fibre in paver blocks has also been studied. Paver blocks containing sludge with different proportions were cast based on the recommendations in IS: 15658 – 2006, the test results were compared with the nominal M20 grade and M30 grade paver blocks. The outcomes of the paver block combinations were studied and found to be an effective utilization of sludge with substantial cement replacement of up to 35% resulting in an effective waste management for specific industries.</p> <p>Implications: Presently, Paver blocks are a construction unit which imparts vast application in street roads and others constructions like walking paths, fuel stations etc. Also, paver blocks possess easy maintenance during breakages. Based on this application, an innovative attempt has been made to manufacture paver blocks incorporated with textile effluent treatment plant sludge and hypo sludge to utilize them with suitable proportions.</p>
