2. Basic idea is to produce best from waste which can be
sustainable & feasible for Environment and Construction
industry as well.

3. • Nagpur 525MLD of sewage, Maharashtra 8,143 MLD Sewage (maximum in
India 13%) and entire country generates-61,948 MLD Sewage.
(Source-Ministry of Environment, Forests and Climate Change (MoEFCC)
• Limestone dust, wood sawdust, processed waste tea and fly ash,One of the most
ignored waste element is sludge.
• We tried dry sludge to replace the soil (partially or/and completely).
INTRODUCTION

4.  An original patent covering the incorporation of raw sewage
sludge into clay bricks dates back to 1889.
 Port Elizabeth brickworks in south Africa has been making
Sludge Bricks since 1979.
