Valorisation of solid wastes in the manufacture of soil based building materials is one of the several technically feasible and cost-effective solutions for waste management. Sugarcane bagasse ash is one such solid waste generated in huge quantities in India, a leading sugar producer. This paper aims at reviewing the valorisation of sugarcane bagasse ash in the manufacture of stabilized as well as sintered earth blocks. Sugarcane bagasse ash is a silica rich material that can play the role of an effective pozzolan leading to enhanced pozzolanic reactions resulting in better performing building materials. The reviewed literature reveals that it has been utilized in the manufacture of blocks as well as tiles in the form of an auxiliary additive as well as a primary stabilizer. However, its utilization in stabilized blocks has been more common compared to sintered blocks due to higher energy consumption in the latter. To summarize, sugarcane bagasse ash not only has improved performance in most of the cases but also has reduced the cost of the material, leading to the conclusion that its valorisation in manufacture of blocks and tiles is a genuine and highly productive solution for waste management as well as cost economy.

Streptokinase is a fibrinolytic enzyme and a product of β-hemolytic Streptococci strains. This enzyme is used as a medication to break down clots in some cases of heart disease. Streptococcus equisimilis, a species of group C Streptococci, is widely used for the production of streptokinase by fermentation technology. In this study, the sugarcane bagasse fermentation medium was optimized for metal ions (KH2PO4, MgSO4.7H2O, CaCO3 and NaHCO3) at various levels to attain the maximal production of streptokinase. Sugarcane bagasse was used due to its profuse availability and as an ideal substrate for microbial processes for the manufacturing of value-added products. The results showed that maximal streptokinase production was found at 0.04% KH2PO4, 0.04% MgSO4.7H2O, 0.15% NaHCO3 and 0.04% CaCO3. Finally, the optimized medium resulted in 84.75 U/mg specific activity and 74.5% recovery. The purification process was carried out simultaneously using ammonium sulfate precipitation, ion-exchange chromatography, and gel filtration. Finally, a purified sample of streptokinase was run on SDS-PAGE and resolute 47 kDa molecular weight. The use of β-hemolytic Streptococci to obtain streptokinase is not free from health risks and is related to anaphylaxis. This study provides a way forward for the cost-effective ways to obtain streptokinase for the treatment of thrombosis.

In recent years, there have been an increasing of solid waste in Malaysia which gave negative effects towards the environments from various aspects such as human health, animal habitat, soil condition and space usage of landfill. This paper study the physical properties of disposable diapers waste which is one type of polymer as building materials. This waste is a fundamental property in reducing the cost effective materials, saving time and help increasing sustainability for the environment. The main objective of this study is to determine the density and porosity of the sample with the present of the disposable diapers waste.

: Wastes such as sugarcane bagasse ash (SCBA) can be used as raw material in ceramics by the elaboration of bricks and tiles and the glass industry, due the high amount of silica in its composition (>70%). Another application for SCBA is the synthesis of metallic silicates. In this work, we study the synthesis of sodium silicate with SCBA as the main raw material and the future application of sodium silicate for the preparation of silica particles in order to create hydrophobic surfaces for ceramic materials to prevent their erosion. The sodium silicate synthesis was carried out by the thermochemical method with batches of ash and sodium carbonate in a 1:1 sodium oxide–silicon oxide molar ratio. The thermal treatment was in an electric furnace at 800 °C for 8 h. Then, for the synthesis of the silica particles, the sodium silicate was dissolved in water, and then we added methanol in a 3:2 water methanol volume ratio. The solution was left to age for an hour to create the Si-OH bond. Finally, tetraethylorthosilicate (TEOS) was added and the solution was stirred for 2 h to create a hydrophobic and hydrolytically resistant siloxane by the displacement of H in the Si-OH bond. The application of the solution was by the spray-coating method over substrates of concrete and red clay with the application of 10, 15, and 20 layers. The hydrophobicity was evaluated with the water contact angle test, with the results of contact angles above the 110°, thus demonstrating the capacity of a waste for the generation of coatings to prolong the useful life of building materials.

Abstract The world is facing pollution crises and these cries are due to improper disposal of waste material. This materials are Rice husk ash, bagasseash, waste marble powder, remanings of grains like rice starw and many more. Some of the waste materials can easily be disposable in the construction industry by using them in the concrete or in any other construction material. This paper deals with this waste material to be utilized in the compressed earth blocks. To study the mechanical properties of compressed soil blocks prepared by a combination of various ratios of Marble powder, paddy Straw Fiber and Sugarcane bagasse ash, the compression test, and water absorption test was performed. The marble powder is introduced in the manner to replace soil by 25%, 35%% and 45 %. Paddy Starws fibers are introducedby the replacement percentage of.6%,.8%and 1% whereas the bagasse ash is been introduced in the manner of 8%,10% and 12%This various test shows that the Marble powder Waste increase dry density which helps in increasing the compression Capacity of the brick. Whereas Paddy Straw fiber and bagasse ash decrease the dry density of brick which results in decreasingthe optimum water content of the mixof the brick. Bagasse ash and paddy straw fiber increase the water absorption capacity of the brick.

The increasing demand and consumption of construction materials create a bottle neck shortage of construction materials this make the researcher and engineer to focus on new material and method for waste reduction and this is for the cost-effective, green and scientific reasons. Sugarcane bagasse ash (SCBA) which is obtained as a secondary product from sugar industry has relatively high silica content has the capacity to react with cement, contribute in increasing the strength of concrete. Copper slag (CS) the secondary manufactured goods from the process of being making copper, it is absolutely lifeless substance that their characteristics are exactly matching with usual sand which is used in construction and may be replaced in concrete. The effect of earthed Sugarcane bagasse ash (SCBA) and copper slag (CS) on the strength and flexural behavior is studied. A total of 25 % SCBA by mass was replaced in case of Portland cement and a total of 60 % by mass of CS was used as a fine aggregate replacement. The strength and flexural behavior of concrete samples were studied using compression test and two-point loading tests. The capacity of the objects framed based on actual concrete and secondary product based concrete were evaluated with standard tests. Five sequence of mixing in concrete proportion were organized by means of SCBA restore cement by 0, 5, 10, 15, 20 and 25% by weight of cement and its 14 & 28 day strength were found out and the other mix with constant SCBA and varying percentage of Copper slag were prepared with 40, 45, 50, 55 and 60 % of copper slag for fine aggregate the 14 & 28 day strength were found. Flexural behavior of SCBA and CS combination were found using RCC beams. It has been engaged that SCBA and CS are better substitute for cement and fine aggregate.

Sugarcane bagasse ash is an offshoot of sugar factories found after burning of sugarcane bagasse which itself is found after the extraction of sugar from sugarcane. The disposal of this material causes environmental problems surrounding sugar factories. Sugarcane bagasse ash is rich in silica that can play the role of an effective pozzolana which leads to improve pozzolanic reactions resulting in better performing building materials. Light weight concrete can be prepared from low density bagasse ash. Surface reactions are improved due to its high specific surface area. Some percentage of cement is replaced with bagasse ash to determine the fresh and hardened properties of the concrete mix. Compressive strength of the concrete can be improved tremendously on later stages of addition of bagasse ash. Incorporating sugarcane bagasse ash in concrete can further alter the other various performance of concrete. Keywords—sugarcane bagasse ash, pozzolana, fresh and hardened properties.
