Production of citric acid from lemon and cassava waste peels

NWOSU F O^*, KAREE A O

The high demand for citric acid by many industries cannot be over emphasized. Presently, 70 % of the total citric acid produced globally is consumed by food industries, 12 % by pharmaceutical industries and the remaining 18 % by other industries. Moreover, rapid increase in food/beverage industries in Nigeria with no known company producing citric acid in Nigeria makes its scarcity severe. Cassava...

Investigation into the Bating Potential of Musa Accuminata (Banana) Peel in the Production of Leather

Bulus Habila^*, Tashi Umar Tijjani, Saidu Simon Moses, Uwanta Emaime Jimmy, Gaiya Jonathan Danladi, Shekarri Ninnas Tachye, Muazu Balarabe Babangida, Ahmed Salim, Igbehinadun Olajide J., Adamu Audu

Increasing environmental pressures are forcing tanneries to reduce the level of nitrogenous compounds in generated effluents, due to strict regulations on effluent quality from various unit processes which bating plays a vital role. Bating imparts smoothness and stretchy effect to the resultant leather with the addition of proteolytic enzymes which are expensive, hence the need for alternative sou...

Nanofiltration Performance of a Functionalized UiO-66 Membrane

Shangkum Yildun Goji^*, Solomon Philip, Rotbe Gurumjib, Lawal Rabiat Abdullahi, Ranga Yusuf Garba, Gongden Joel Japhet, Yoila Dakup Kitgak, Simon Kwene Dangkat

This research investigates the design principle for metal organic frameworks (MOF) deposited composite membranes for nanofiltration using functionalized/modified UiO-66 (UiO stands for University of Oslo) nanoparticles for the purpose of exploring the importance of functional groups around the nanopores. The nanoparticles were synthesized using water as modulator and characterized by XRD, FTIR,...

Evaluation of Compacted Black Cotton Soil – Sawdust Ash Mixtures as Road Construction Material

Yohanna P.^*, Mannir I., Osinubi K. J.

This study was aimed at the evaluation of the stabilization potential of sawdust ash (SDA) on black cotton soil. Soil samples were treated with up to 10 % SDA content by dry weight of soil compacted with reduced British Standard light (RBSL) energy. Index properties of the natural soil showed that the soil belongs to A-7-5 (36) in American Association of State Highway Transportation Officials (AAS...

Physicochemical properties of terminalia avicennioides (ta) and anogeissus latifolia (al) gum

Omoniyi K. I.^*, AMEH P. O, USMAN U

The work reports the physicochemical properties of gum exudates from two Combretaceae tree species (Terminalia avicennioides (TA) and Anogeissus latifolia (AL)) determined by standard methods. The gum exudates exhibited differences in physicochemical qualities. The physicochemical properties of the gum were in the following ranges: moisture (11.3 - 11.5%); swelling capacity at 30oC (11 - 13%); pH ...

Potential of Manihot Esculenta (Cassava) Peels for Electricity and Heat Co-Generation in Nigeria

S. I. Kuye^*, Oyeniran Timothy O, Adekunle Nurudeen Olatunde, Benedict Uche Anyanwu, Olamide O.O

Nigeria is the largest producer of cassava in the world and the peel accounts for between 5 -15% of the tuber. Cassava peel is often left unattended in the country, making it a source of methane gas which is one of the culprits of global warming. Agricultural residues are good sources of renewable energy. This study investigated the potential of electricity and heat generation from cassava peel...

Microstructure and Hardness Profiles of Hybrid Laser-Arc Welded Joint for UltrahighStrength Steel.

Olugbade Emmanuel^*, Zhou Bin, Ikeagwuonu Clement, Yang Li, Huang Gen-Zhe

In this investigation, hybrid laser-arc welding was performed on 6-mm thick ultrahigh-strength quenched and tempered steel plates. Laser-arc welds were characterized for hardness and metallurgical properties in three defined cooling cycles. Destructive tests of the joints revealed that the joints were characterized by tensile strength similar to that of the base material. Microstructural charac...
