Trends in the development and utilization of agricultural wastes as heterogeneous catalyst for biodiesel production

Abstract: Biodiesel is unarguably one of the most considered substitutes for fossil-based liquid fuels. However, the high cost of biodiesel production has been a major inhibitor for its large-scale activity. Apart from the cost of feedstock, catalysts contribute to the high pump price of biodiesel. Wastes derived from agricultural sources have been seen as viable means of synthesizing cost-effective and environmentally friendly catalysts and is an appropriate disposal of wastes. In this study recent trends in converting and utilizing agricultural wastes as heterogeneous catalysts for biodiesel production were reviewed. Agricultural wastes classifications, types of catalysts for biodiesel production, and the effects of conversion and modification techniques on pore size, acidity, surface area, and other fingerprints that enhance the catalytic activity were discussed. The use of characterization methods to test the suitability of solid catalysts was analysed, and some published works on the use of some agricultural wastes-derived catalysts were scrutinized. The paper concludes that catalysts derived from agricultural wastes offer a cheap, readily available, easy to produce, and environmentally benign replacement for the imported commercial ones. Going forward, more target investigations are needed on the suitability of some unexplored agricultural wastes to convert them to green catalysts. Researchers should explore the use of optimization models and statistical tools to determine the appropriate conditions for effective performance of biofuels.

Modified clay minerals for environmental applications

Abstract: Clays and clay minerals are one of the important groups of materials that are widely used in environmental cleanup applications. The natural clay minerals are hydrophilic in nature, and hold high chemical stability and cation exchange capacity. Owing to the native electronegative surface properties and cation exchange capacities, natural clay minerals are good adsorbents of heavy metal cations and many other cationic organic contaminants. The modification of clay minerals can significantly improve their surface properties that consequently increase their contaminant removal capacities and efficiencies. The current chapter presents a brief overview of various clay modification and surface engineering methods, and discusses how the resultant modified clay products can remediate various environmental contaminants.

Nutrient, phytochemical, and antinutrient composition of Citrus maxima fruit juice and peel extract.

Abstract: Nutrient, phytochemical, and antinutrient composition of Citrus maxima fruit juice and peel extract were determined. The fruit was procured from a garden in Trans-Ekulu, Enugu East Local Government Area, Enugu State, Nigeria. Mature undamaged Citrus maxima fruits were thoroughly washed with distilled water to remove contamination, dirt, and air-dried. The peel was separated from the pulp. The pulp (100 g) was blended and filtered through a muslin cloth to obtain a clear juice. The peel (50 g) was macerated with 200 ml of ethanol for 20 min. The peel extract was filtered through filter paper. The supernatant was concentrated by rotary evaporation. The peel extract was weighed and stored in a plastic container until needed. Proximate, mineral, vitamins, antinutrient, and phytochemical composition of the juice and peel extract were determined using standard procedures. Citrus maxima peel extract contains significantly (p Na > Ph > Fe > Mg > K in the juice and Ca > Ph > Na > Fe > K > Mg in the peel extract. Vitamin C content of the juice and peel extract were 26.36 mg/100 g and 19.34 mg/100 g, respectively. Citrus maxima peel is highly nutritive and rich in phytochemicals, further research is recommended to investigate its therapeutic effect.
