“…Depending on the source of the sugarcane, harvesting methods and thermal conversion efficiency at the mill, the percentage of ash produced from bagasse typically represents a small percentage, 1.5 to 3.0% by weight, of the original sugarcane bagasse (Amin, 2011;Garcıà-Pèrez, 2002). And, although SBA content is low (1.5-3.0%) compared to other agricultural sources such as rice straw, 14.5% (Guo et al, 2009) and wheat straw, 8.6% (Biricik et al, 1999), the large volume of bagasse used for fuel results in massive amounts of SBA that necessitates economically and environmentally handling. If the estimated 80% (Pandey et al, 2000) of the 3.5 million mg of bagasse produced each year in Louisiana is used for energy conversion at the sugarcane mills, the SBA produced in Louisiana each year would range from 42,000 to 84,000 mt, and an estimated 2.25 to 4.5 million mt of sugarcane bagasse ash globally.…”

Sugarcane bagasse is the fibrous material remaining after removing the sucrose, water, and other impurities (filter mud) from the millable sugarcane. Louisiana sugarcane mills use a portion of the sugarcane bagasse to produce steam power to run equipment within the mill and/or as a boiler fuel for the clarification, evaporation, and crystallization processes. Sugarcane bagasse ash (SBA) is a by-product of the thermal conversion of the sugarcane bagasse. The purpose of this research was to investigate the use of SBA as an amendment to soilless planting media for the production of vegetable seedlings. The SBA was combined by volume with a commercial certified organic soilless growing media into 5 combinations (0%:100%, 25%:75%, 50%:50%, 75%:25%, and 100%:0%, SBA and growing media, respectively). Bean (Phaseolus vulgaris L.) var. 'Bowie' and Chinese kale (Brassica alboglabra) var. 'South Sea' were planted in each of the 5 different planting mixtures. As the percentage of SBA increased from 0% to 100%, the bulk densities increased, 0.118 to 0.712 g/cm 3 , while the porosity, water saturation percentage, and water at field capacity decreased. Increasing the SBA percentage significantly impacted total exchange capacity, pH, organic matter, estimated nitrogen release, and all other nutrients measured, except for sodium. The research indicates that the addition of SBA can enhance bean and Chinese kale seedling growth depending on the percentage of the ash added to the growth media. Bean and Chinese kale harvest parameters typically peaked at 25% SBA, and then decreased with increasing SBA %. Adding 25% SBA did benefit the seedling growth by providing additional nutrients for seedling growth, while reducing the cost of production by supplementing the more expensive greenhouse media by a readily available by-product of the sugarcane industry. Increasing the SBA % to 50% or greater is not recommend. Additional research is needed to determine the percentage above 25% and below 50% SBA that would still benefit seedling plant growth.

Bagasse is the fibrous material remaining after removing the sucrose, water, and other impurities (filter mud) from the milable sugarcane. Louisiana sugarcane mills use a portion of the sugarcane bagasse for fuel producing over 20,411 mt of sugarcane bagasse ash (SBA) as a by-product. The purpose of this research was to investigate the use of SBA as an amendment to soilless planting media for the production of vegetable seedlings. The SBA was combined by volume with a commercial soilless growing media into 5 combinations (0%:100%, 25%:75%, 50%:50%, 75%:25%, and 100%:0%, SBA and growing media, respectively). Squash var. 'Straightneck' and cantaloupe var. 'Magnum Hybrid Melon' were planted in each of the 5 different planting mixtures. The research indicates that the addition of SBA can enhance squash and cantaloupe seedling growth depending on the percentage of the ash added to the growth media. Squash plant stalk lengths and total plant fresh weights (stalk, leaves, tops, roots, and total plant) overall responded best at the 75% SBA. Squash dry weights were consistently greater when SBA was added to the soilless media compared to no SBA. The 25% and 50% SBA media produced the greatest cantaloupe leaf fresh weights. Cantaloupe leaf dry weights followed a similar trend, where the 25% and 50% SBA media produced greater plant weights with lesser yields observed at the 75% and 100% SBA levels. This data suggests that the 75% SBA and 25% SBA were certainly suitable potting media combinations for squash and cantaloupe seedling production, respectively.

“…Industrial wastes, such as blast furnace slag, fly ash and silica fume are being used as supplementary cement replacement materials. In addition to these, agricultural wastes such as rice husk ash, wheat straw ash, and sugarcane bagasse ash are also being used as pozzolanic materials and hazel nutshell used as cement replacement material [2][3][4][5][6][7][8][9][10][11]. When pozzolanic materials are added to cement, the silica (SiO 2 ) present in these materials reacts with free lime released during the hydration of cement and forms additional calcium silicate hydrate (CSH) as new hydration products [12], which improve the mechanical properties of concrete formulation.…”
