Eco-Friendly Utilization of Ceramic WTP Sludge

The global tile production has surpassed 13 billion square meters, reaching 13,552 million square meters. In 2017, India emerged as the second largest tile producer and consumer, with an annual production of 1.08 billion square meters, primarily centered in Morbi, Gujarat. However, the ceramics industry produces a lot of waste, ranging from 15% to 30% of total production. This waste is often improperly dumped, causing air and land pollution. To mitigate environmental impact, recycling ceramic waste is crucial. Recycling offers multiple benefits, including environmental protection, reduction of disposal issues, and cost savings on landfilling. Additionally, it conserves natural resources like aggregate and lime and reduces harmful CO2 emissions from cement production.This paper explains the applications of ceramic waste water sludge in the ceramic and construction industry. The tile industry, known for its water-intensive processes, can benefit from sustainable practices to ensure long-term viability and minimize the impact on local water resources. The specific surface area of sludge from vitrified porcelain stoneware tile is 6980 cm²/g. Similarly, sewage sludge is a disposal challenge for it is the increasing volume generated by expanding sewage treatment facilities. Finding sustainable reuse methods for sewage sludge is essential for managing disposal limitations and promoting sustainable development.
