A theoretical procedure has been developed with the aim of obtaining an accurate and rapid estimation of the degree of crystallisation in jarosite glasses by measuring the densities of the parent glass and, after the thermal treatment, of the glass-ceramic. Compositions were prepared by mixing jarosite waste with granite scraps and glass cullet, yielding three di€erent glass-batchs, melted at 1...

Water flow is an essential factor in the sealability of any underground cavern, including those for nuclear waste disposal, and significantly affected by permeability rock. The rocks various factors, stress temperature. rock changes excavating a temperature decay heat from waste, change induces thermal stress. Therefore, water around such caverns must be evaluated considering effects Numerical ...

in this work, the waste stone sludge obtained from the granite and marble stone processing factories was used for the manufacture of artificial stones using vibratory compaction in a vacuum environment. the results obtained showed that water absorption and density increased, and the flexure, compressive, and tensile strengths decreased with increase in the content of the waste stone sludge. the...

The temperature-phased anaerobic digestion (TPAD) process was used for the anaerobic digestion of the source separated biodegradable organic fraction of municipal solid waste (OFMSW). The TPAD process was used to co-digest OFMSW with primary wastewater solids (PS) at ratios of 20:80, 40:60, 60:40, and 80:20 O FM SW :PS. Th e OF MS W/P S feed mixtu re wa s slurrie d at co ncen trations up to 5.2...

This research aimed to evaluate the effectiveness of various diffusers in a bioreactor for producing liquid organic fertilizer (LOF) using cow urine and slurry waste as materials. LOF was produced by treating with Urine-Single Orifice Diffuser (USOD), Urine-Coarse Bubble (UCBD), Urine-Fine (UFBD), Slurry-Single (SSOD), Slurry-Coarse (SCBD), Slurry-Fine (SFBD) equipped water pump an external aer...

Kitchen (food waste) was collected from hostels of Cancer Hospital & Research Institute (CHRI), Gwalior’s Mess as feedstock for bio-reactor which works as anaerobic digester system to produce biogas energy. Production of biogas ,used as energy source, will be more cost effective, eco-friendly, cut down on landfill waste, generate a high-quality renewable fuel, and reduce CH4 and CO2 emissions, ...
