Novel lightweight bricks have been produced by sintering mixes of dried water treatment sludge and rice husk. Samples containing up to 20wt.% rice husk have been fired using a heating schedule that allowed effective organic burn-out. Rice husk addition increased the porosity of sintered samples and higher sintering temperatures increased compressive strengths. Materials containing 15 wt.% rice husk that were sintered at 1100 degrees C produced low bulk density and relatively high strength materials that were compliant with relevant Taiwan standards for use as lightweight bricks.

Amine-functionalized biogenic silica incorporation effect on poly (ether-block-amide) membrane CO2/N2 separation performance

Wahyu Kamal Setiawan, Kung-Yuh Chiang

Summary: In this study, biogenic silica (BSi) was extracted from rice husks and functionalized using three different molecular structure amine groups. The functionalized silica was combined with Pebax-1657 to form mixed matrix membranes (MMMs), which showed significantly improved CO2 permeability and CO2/N2 selectivity compared to Robeson's upper bound 2008. Among them, Pebax/BSi-MAPS-10 was the most reliable membrane. These findings suggest that amine functionalized BSi has great potential for CO2/N2 separation in industrial applications.

Maria Georgiades, Izhar Hussain Shah, Bernhard Steubing, Christopher Cheeseman, RupertJ. Myers

Summary: This study quantifies the potential CO2-eq. emissions reductions in cement production in Europe until 2050 by employing measures such as clinker substitution, alternative fuels, kiln improvements, and carbon capture and storage. The results show that significant reductions in CO2-eq. emissions can be achieved by 2050 through these measures, with additional reductions possible through decarbonisation scenarios for the electricity mix. Multiple pathways exist for the cement sector to achieve and surpass global climate targets.
