---------------------------------------------------------------------***-----------------------------------------------------------------Brick manufacture contributes to Green House Gases and Abstract - The disposal of sewage treatment plant waste, specifically sewage sludge, has raised significant environmental concerns. This research focuses on investigating the suitability of different soil types (Kanota soil, Samodh soil, and Black cotton soil) obtained from diverse locations, in combination with wet and dry forms of sludge collected from Dehlawas (unit-1), ASP(Activated Sludge Process ) based ,Sewage treatment plant Jaipur. The objective is to identify optimal clay-sludge combinations that can be utilized as environmentally friendly construction materials. The study evaluates six distinct scenarios encompassing various combinations to determine the most viable clay-sludge combination. Challenges encountered in the experimentation include cracking during the drying process and the onset of anaerobic decomposition, etc. Notably, the second scenario involving Kanota soil with dry sludge demonstrated significant issues, with all 70 bricks exhibiting cracks, emitting odor, and experiencing breeding problems. Conversely, the third scenario utilizing fresh wet sludge with Kanota soil yielded favorable outcomes. In the fourth scenario, the utilization of burnt sludge with Black cotton soil led to a shrinkage problem, causing a substantial reduction in brick length of approximately 1 inch, attributable to the nature of the clay, i.e., Black cotton soil. The sixth scenario, involving fresh wet sludge with Samodh soil, also proved successful, as bricks with 5%, 10%, 15%, and 20% wet sludge replacement (by weight) exhibited no cracks, while minor cracks were observed with a 30% wet sludge replacement. Furthermore, it was observed that the compressive strength of the bricks decreased as the sludge content percentage increased.
Black Carbon emissions, both of which have a substantial influence on human health and climate change. Furthermore, the brick manufacturing industry is distinguished by the extensive exploitation of natural resources such as clay reserves.

3. STATUS OF WASTE WATER TREATMENT FOR RAJASTHAN STATE
Global representatives discussed the unprecedented challenge of climate change at the United Nations Climate Change Conference of Parties in Glasgow and Sharm ElSheikh (Egypt), because the climate crisis, sustainability, and food security are essential and urgent topics in all countries.
2. NECESSITY OF STUDY IN INDIA CONTEXT The building and maintenance sector is a critical economic driver in India. The industry is vital to India's overall growth, and the government places a high priority on implementing laws that will assure the country's timely building of worldclass infrastructure. According to NITI Aayog, the Indian real estate sector would be worth $1 trillion by 2030 and will contribute for 13% of India's GDP by 2025. According to the Union Budget of India, during the fiscal year 2022-23, 80 lakh dwellings would be completed for the identified qualified beneficiaries of the PM Awas Yojana, in both rural and urban areas, to facilitate cheap housing, with traditional fire bricks being used in most cases.

Rajasthan State was one of the states that announced its own State Sewage and Waste Water Policy in 2016, with a focus on the reuse of treated wastewater and the promotion of public awareness programs.
1. INTRODUCTION For thousands of years, bricks have played an important part in building and construction. Despite its dependability and accessibility, it is commonly acknowledged that manufacturing burnt clay brick remains an energy- and highly resource-intensive operation. Many academics have been undertaking a wide range of studies on sustainable and creative bricks in order to reduce the brick industry's significant carbon impact.

According to information available from the concern department of Government of Rajasthan, and RSPCB (Rajasthan State Pollution Control Board) Jaipur, total sewage generation is approximately 1550.00 MLD from 116 operational STPs in 33 towns across the state, and total sewage treated through STPs (Sewage Treatment Plants) is approximately 723.00 MLD. As a result, the proper disposal
