The possibility of using plastic waste to manufacture hybrid bio-composite materials with the dry husk of Asian rice (Oryza sativa L.) is investigated. The most polluted and unsustainable plastic waste is High-Density Polyethylene (HDPE) due to its single-use, which decreases in quality if it is reused is selected. The mixtures chosen are local natural fiber and easy to find, potentially a preliminary study of a composites building material. Furthermore, to improve the tensile properties of this hybrid bio-composite material, an additional organic filler is used, such as rice husk (Oryza sativa L.) in a combination of 10%, 12%, and 15%. Samples for this study were processed using the hot press methods based on ASTM D882. Tested for tensile strength, modulus young, yield stress, and elongation is carried out to see an increase in the performance of the biocomposite material. The test results show that the best tensile properties are samples with 12% rice husk, resulting in excellent sample compatibility proofed by Scan Electron Microscopy to study bio-morphological composites. This project has shown that the composites based on natural fiber will be potential building materials due to their improved tensile properties.

Rice Husk Biochar

Rice husk biochar (RHB) and phosphate rock (PR) are locally accessible resources that poor farmers in Sub-Saharan Africa (SSA) can utilize to increase rice productivity. However, biochars are variable depending on feedstock, pyrolysis temperature, and duration. Phosphate rocks from SSA are of low solubility. The goal of this study was to determine whether pyrolysis of rice husk (RH), calcination of PR, and the calcination/pyrolysis of a RHB-PR mixture at 300 °C, 500 °C, and 700 °C can increase formic acid (FA)- extractable phosphorous (P). The properties of these RHBs were compared to the properties of RHB produced through a simple farmer-friendly pyrolysis technique termed “Kun-tan”. Properties of calcinated PR were also compared to the raw PR. Quartz formed from amorphous SiO2 during RH pyrolysis and was the dominant mineral phase in the biochars, irrespective of the pyrolysis temperature. Formic acid-extractable P content, pH, and ash content of the biochars increased with increasing pyrolysis temperature. At 700 °C, FA-extractable P content of the RHB was 219% more than the feedstock. Hydroxyapatite and quartz were the dominant minerals in the PR irrespective of calcination temperature, indicating that hydroxyapatite and quartz were stable to at least 700 °C. Rather, calcination decreased the FA-extractable P content of the PR.
