2023 JUL 12 (NewsRx) -- By a News Reporter-Staff News Editor at Economics Daily Report -- Researchers detail new data in sustainability research. According to news reporting out of Mepco Schlenk Engineering College by NewsRx editors, research stated, “The disposal of paper mill sludge waste generated by the paper industry is a tough and challenging task.”

The news correspondents obtained a quote from the research from Mepco Schlenk Engineering College : “In this work, an attempt is made to develop various value-added products namely bricks, briquettes, ground chakra base, and eco-friendly composites from the secondary paper mill sludge (PMS). The secondary PMS was initially dewatered to remove the moisture content, ground to powder, and mixed with cement, MSand. quarry dust, and fly ash to produce bricks. The brick specimens were tested for compressive strength, water absorption, and efflorescence as per the standards and found to be 5.29 ± 0.11 N/mm2, 3.84 ± 0.13% respectively, and have NIL efflorescence. The PMS is mixed with paraffin wax and compressed in a squeeze moulding to form briquettes and observed that the percentage of ash content in the briquette is 66.6% which is less than that of the PMS. Further, a ground chakra base is produced using a slurry of starch and dried in a heater at 60° exhibiting better properties.”

According to the news reporters, the research concluded: “An eco-friendly composite pottery product was developed by mixing PMS, clay, and starch and tested for breakage.”
