Introduction. Spent potlining is a hazardous waste produced in the pot rooms of aluminum smelters. This waste is generated from the internal lining of aluminium (Al) cells consisting of carbon and refractory bricks, which are replaced after five to eight years of service life. SPL is classified as a hazardous waste because of its contamination ...

The solution to save environment from harmful effects of SPL is recycling it and using it in cement industry and iron making purposes after treatment [22]. In cement industry, SPL first cut is used. Using SPL saves the input of fuel as it has high calorific value and fluoride in it reduces the melting point of clinker [23]. One more effective ...

distillery spent wash was done in concrete (Arunvivek, 2013). It was also concluded that wide use of distillery spent wash in the construction industry saves cement, improves the quality of concrete mixes and solves ecological problems. Cane molasses was used for the stabilization of expansive soil (Julius, 2011).

The physical properties of spent garnet are given in Table 1. Spent garnet possess high specific gravity (2.9–4.2) and bulks density which falls between1922-2300 kg/m 3. The water absorption of spent garnet was found to be 5.8–11.4% higher than sand. Sieve analysis indicates it is a well graded material [39].

A typical physico-chemical characteristics of distillery spent wash is depicted at Annexure- I. The production of cement in India is about 200 Million Tonnes per annum. The country, therefore, has potential to utilize spent wash concentrate from the distilleries for co-processing in cement industry.

The distillery spent wash (DSW) is a liquid waste that is produced from the sugarcane industry. It contains a large load of both organic and inorganic substances.

Additionally, the cement industry puts an upper limit to SPL usage amount of 0.2% by mass and restricts the inclusion of metal particles such as Al which are damaging in the finished cement. ...
