New Zealand's extinct flightless moa radiated rapidly into a large number of morphologically diverse species, which produced an equally large range of egg morphologies. The exact number of moa species, as well as the characteristics of the eggs they laid, remains contentious. Moreover, like most extinct species, we understand little about their nesting and incubation habits. We used a modified ...

Eggshell has a shaft and high surface area, so it the potential to become an adsorbent. The adsorbent is in filtration process. Waste cooking oil can be reused as raw material with economic value. So far, waste bank that accommodates used not gone through process, selling price low. filtered using various media, including activated carbon, commercial silica, local adsorbents such eggshells. A p...

Eggshells are daily food waste disposed of in landfills, producing environmentalissues and an unpleasant odour. were crushed to form eggshell powder may be suitably applied as a filler epoxy resins improve their mechanical properties. The shear strength toughened with (TEEP) wasstudied. Single-lap joint (SLJ) sheartests conducted toinvestigate the SLJbonded different volume fractionsof TEEP. Fo...

In order to obtain the cheap waste calcium-based sorbent, three wasted CaCO3 precursors, namely carbide slag, chicken eggshells, and analytical reagent-grade calcium carbonate, were selected prepared at 700 °C form sorbents for CO2 capture. TGA was used test uptake performance of each sorbent in 20 cycles. To identify decay mechanism with an increasing number cycles, all characterized by using ...

Further research is needed to try utilize calcium carbonate from chicken eggshells as an adsorbent. The use of adsorbent expected minimize the amount waste generation and reduce environmental pollution. This aims Eggshell powder was activated with 0.1 M HCl solution for 48 hours, then heated in oven at 150°C 30 minutes which enlarge pores, increase surface area, volume create new pores that wil...
