Abstract:
The present work aimed at incorporating the rice hull ash (RHA) into a polypropylene polymer matrix. The methodology applied was the case study, whereby the rice hull, residue generated during the grain extraction, was used in the present study. The samples were prepared with the addition of a coupling agent (silane) with 10% by mass in relation to the filler, to improve the characteristics of the ash/ matrix interface. The tensile test results showed that the modulus of elasticity increased proportionally to the addition of the RHA contents, promoting an increase in the material stiffness. Th

ABSTRACT A model procedure has been developed for the rapid extraction of five bacteriocins (nisin, pediocin RS2, leucocin BC2, lactocin GI3, and enterocin CS1) from concentrated freeze-dried crude culture supernatants by adsorption onto acid or alkaline rice hull ash (RHA) or silicic acid (SA). Bacteriocins were adsorbed onto RHA or SA by a pH-dependent method and desorbed by decreasing the pH to 2.5 or 3.0 and heating at 90°C for 5 min. The maximum adsorption and optimal pH range for different bacteriocins were as follows: nisin, 97% at pH 7.0; lactocin GI3, 94% at pH 6.0; pediocin RS2, 97%

At present, the research on rice hull ash and cement-based materials as cementitious materials continues to deepen. Low-cost rice hull ash replaces part of Portland cement, which plays a dual role in saving material costs and improving environmental benefits.

Abstract:
Rice hull ash (RHA) is a by-product of the rice industry. RHA is produced when rice hulls are incinerated, for example, when they are used to power steam engines in rice milling plants. Typically, this ash is disposed of in landfill sites, which may cause environmental problems. RHA has a naturally occurring silica content that is very high, ranging from 95 to 98%. This high silica content makes RHA a potential filler for polymer products. The aim of this project was to investigate the application of RHA as a filler in polypropylene.

Abstract:
Rice husk ash (RHA) is a by-product of rice milling. Its use as soil stabilizer is a way to replace the final disposal with environmental benefit. However, RHA is not cementitious itself but when mixed with lime forms cements which improve the soil properties. A research of performance of a silty sandy soil modified with RHA and lime as wearing course layer of low-volume roads was conducted through two full-scale test sections with different pavements built in Artigas, northern Uruguay. The alkaline reactivity of RHA is low because the husk burning is not controlled. The soil-RHA-lime mix desi

Abstract:
Abstract: This study uses used engine oil (UAO) as a chemical additive to examine the effects of rice husk ash (RHA) and sawdust ash (SDA) as cement substitutes on the durability characteristics of self-compacting concrete (SCC). Eight (8) distinct mixes were prepared and proportioned, with RHA replacing cement by weight at percentages of 0%, 5%, 7.5%, and 10%. In addition, SDA replaces cement ingredients concurrently by weight at 0% and 5% and with a constant UAO of 0.5%. The properties of fresh SCC concrete that contained RHA, SDA, and UEO were assessed, along with the concrete's water absor
