Recently, researchers are focused on the use of biomasses generated in oil palm industry as compost to overcome their negative impacts and recycle them to produce a useful byproduct for agriculture. This study investigated formation of compost from Palm Oil Biomass (POB) by adding Cow Dung (CD). The experiment was carried out under shade in plastic bins at different POB and CD ratios (4:0, 3:1, 1:1 and 1:3) to activate decomposition mechanism up to 11 weeks. Decomposing materials was frequently moistened and turned accordingly. The addition of CD has facilitated the composting process and treatment with 1:3 ratio of POB and CD had better quality than other treatments such that the C/N ratio, the Electrical Conductivity (EC) and pH for mature compost were 22.2, 2.83 mS.m−1 and 7.81 respectively.

Nanoparticles (NPs) have properties for potential applications in different areas but their conventionalproduction processes are often linked to secondary health and environmental impacts. Aggressiveresearch endeavors are being undertaken to identify greener NPs synthesis strategies. Green synthesis isan evolving area with the objective of an efficient and environmental friendly development of NPs. Biological substances including bacteria, fungi, yeast, algae, and plant have been demonstrated to beapplicable for the synthesis of TiO2 NPs. This work is dedicated to phyto-based biosynthesis of TiO2 NPs. Biomolecules in plants such as terpenoids,flavones, ketones, aldehydes, proteins, amino acids, vitamins,alkaloids, tannins, phenolics, saponins, and polysaccharides can play vital roles as a reducing, cappingand stabilizing agent in the formation of TiO2 NPs. A systemic comparison is made with the focus on thebioreduction ability of different plant extracts to produce specific TiO2. Important results of applicableinstrumentation techniques for characterizing the TiO2 NPs are also elucidated to identify the superiorqualities of the NPs. Moreover, photocatalytic and antimicrobial applications of the phytosynthesizedTiO2 NPs are also critically discussed. The main scopes are the current status of plant- assistedbiosynthesis of TiO2 NPs and future prospects of this promising area of research.

The potential of using pumice and walnut wood activated carbon as low-cost adsorbents for the removal of the diazo dye Reactive Black 5 (RB5) from aqueous solutions was investigated. The Langmuir isotherm fit to the data specified the presence of two different natures of adsorption sites with different binding energies on the AC-W surface. Kinetic modelling showed that the adsorption behaviour and mechanism of RB5 for both adsorbents is believed to happen via surface adsorption followed by diffusion into the pores of the AC-W and pumice. The main adsorption mechanisms are hydrogen bonding, electrostatic bonding and n–π interactions.

Polyaniline Sn(IV) tungstomolybdate nanocomposite (PSTM) was synthesized by sol–gel method. Thephysico-chemical properties of PSTM were studied using FTIR, TGA, XRD, SEM, and TEM. The materialwas successfully used for the removal of Pb2+. Batch experiments were performed as a function of variousexperimental parameters such as effect of pH (2–8), contact time (5–60 min), initial Pb2+ concentration(10–30 mg L 1) and temperature (20–50 8C). The removal rate of Pb2+ using PSTM was fast andequilibrium established within 50 min. Kinetic studies showed better applicability for pseudo-firstordermodel. The values of thermodynamic parameters (DG8, DH8 and DS8) were also computed.
