Three molasses obtained from different sugar factories are used in this study at two admixture dosages, such as 0.4% and 0.7% of cement dosage. Two types of concretes are prepared with two cement dosages, such as 270 and 320 kg/m 3, respectively.

The major problem associated with the molasses industry is the production of large quantities of brown-colored effluents known as spent wash. It has been reported that molasses spent wash in alcohol fermentation is nearly 15 times of the total amount of alcohol pro-duced [8]. Disposal of such huge quantity of waste stream without
The molasses-based fermentation industry produces a very large quantity of spent wash as waste which is a major concern for distillery industries who want to realize the concept of Zero-Liquid ...
Problems with Incineration of spent wash • Solids content of spent wash is to be brought to about 60% before firing into the furnace. • This brings the economics down as it is energy intensive. Also, damaging to the material of construction. • Spent wash is sticky • It swells (up to about 5 times the original volume) while heating
Studies have shown that admixtures based on molasses increase the quality of concrete by reducing water-cement ratio thanks to its water-reduction property (Canbaz et al., 2011). Molasses improves the workability and fluidity of fresh concrete and delays setting period of cement paste (Jumadurdiyev et al., 2004).

Reduction of cement ratio by using molasses in concrete decreases the cement production and provides a more environmental-friendly carbon dioxide emission. …
Molasses is suitably diluted in order to have desired sucrose level in it. It is then supplemented with assimilable nitrogen source like ammonium sulphate or urea. It is also supplemented with phosphate if necessary. The pH of the fermentation broth is adjusted to below 5 using sulphuric acid.

Cement paste with varying dosage of molasses; 0.0%, 0.025%, 0.05%, 0.075%, 0.1%, 0.15%, 0.2%, and 0.3%, by weight of cement was prepared. The result of the setting time is presented as a percentage change between the various molasses dosages and the control mix by using the following equation:
It was also concluded thatwide use of distillery spent wash within the housing industry cement, improves thequality of concrete mixes and solves ecological problems. Cane molasses was used for thestabilization of expansive soil (Julius, 2011). Stabilization of black cotton soil with molasses

The aim of the present research was to investigate the decolori- zation of molasses spent wash by using a novel adsorbent. The ad- sorbent was fabricated from a mixture of charcoal fly ash and clay. The performance of the fabricated adsorbent was evaluated in a series of batch experiments.

Most of the industries use anaerobic digestion of spent wash for partial treatment, which produces methane as a by-product. The partially treated spent wash is called Biomethanated Spent wash and the same cannot be disposed directly into environment, since it has considerable concentration of organic and inorganic matter.

Currently, alcohol production is based on the use of non-waste agricultural substrates, such as cereals, potato starch, molasses from sugar beet, beetroot, and fruits [5]. Ethanol fermen- tation can be performed with any naturally occurring sugar, starch, or cellulosic material combined with the appropriate pretreatment.

The processing of sugarcane generates bagasse, molasses and press mud which has great economic value. Besides these main by-products, there are other residues which are produced from sugarcane and have less commercial value such as trash, green tops, wax, fly ash and spent wash.
Distillery spent wash refers to the effluent generated from alcohol distilleries. On an average 8–15 L of effluent is generated for every liter of alcohol produced [1]. The alcohol distilleries are extensively growing due to widespread industrial applications of alcohol such as in pharmaceuticals, food, perfumery, etc.
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.
