The potential of banana peel (BP) on the cesium removal from aqueous solutions is study by using different design parameters by adsorption process. The design parameters studied to adsorb cesium using BP as an adsorbent material were initial concentration of cesium , absorbance material packing height which was BP, pH of cesium feed inlet, treatment time, feed flow rate and feed temperature, results show that the higher removal efficiency was 97.50 % for cesium from aquatic solution and this efficiency was decreased with increasing of initial concentration and flow rate while the removal efficiency increased with increasing pH, sorption media bed height and feeding temperature. By this way we can possess different benefits which are: remove the hazard and toxic cesium contaminated the water and get rid of waste BP.

The production of environmentally friendly, sustainable plain concrete slabs is an essential requirement in this work. It is interesting to note that the ions of lead of wastewater loaded into rice husks can be used as an additive for plain concrete slabs to improve the flexural strength, as well as the workability of plain concrete slabs (or walls), which are produced by using Lead-loaded rice husk material as an additive substance in protective shields for the establishment of hospital radiology rooms. The results show that flexural strength for plain concrete slabs begins with a relative increase until it reaches breakdown. The results at age of 28 days also show that by increasing the proportion of Lead-loaded rice husk added to plain concrete slabs, the flexural strength gradually increases until it reaches one-third of the value of reference plain concrete slabs at a specific ratio, then decreases sharply until the slabs fail. These results provide a novel approach to managing toxic waste and propose an easy, simple, effective, economical, and environmentally friendly way to get rid of more than one type of waste and reach the concept of zero residue level.

This study investigates the efficacy, performance, and effect of chopped Copper Fibre (CF) on a Pure Gypsum (PG) mixture. The Copper Fibre (CF) is extracted from the waste of electrical wires that are considered as environmental waste. Three models of Copper Fibre (CF) with a diameter of 0.83 (mm) and lengths of 10 (mm), 20 (mm), and 30 (mm) (Aspect-Ratio L/d = 12, 24 and 36 respectively), with Volume Fraction (V.f.) for Copper Fibre (CF) by two Water/Gypsum Ratios (W/G) worth (0.5 and 0.6) are created. The mixtures are divided into two groups of W/G ratios. Each group contains four samples, one reference without Copper Fibre (CF) and the other three with the addition of Copper Fibre (CF) individually with different lengths. The results show that adding Copper Fibre (CF) to the Pure Gypsum (PG) mixture increases the Compressive Strength. Further, the effect is to heighten the Compressive Strength of Pure Gypsum (PG) when the Aspect-Ratio is raised. In other words, when the (W/G) Ratio is reduced, the Compressive Strength increases in the presence or absence of Copper Fibre (CF). Moreover, the efficiency of the Copper Fibre (CF) develops further when the W/G ratio is decreased.
