Suitability of Reusing the Spent Diatomaceous Earth in Brick Production: A Review

Diatomaceous Earth (DE) is commonly used as a filter material in the brewery industry. Spent (SDE) an industrial waste generated after filling DE pores with impurities from brewing industries during filtration. After final filtering process, this SDE disposed into dumping areas, causing numerous environmental concerns. has been recently reported substitute for clay brick production. Incorporating production can reduce amount of added to and discharged environment. However, only limited literature available on utilization This paper reviews recent research reusing Moreover, manufacturing process bricks, including essential chemical reactions accompanying firing brick, properties clay, factors maintained affecting quality have also discussed review.
