Studies were carried out for 90days on the degradation of wood wastes of four economically important Nigerian trees; Terminalia superba, Mansonia altissima, Holoptelia grandis and Milicia excelsa by white rot fungus, Pleurotus tuber-regium a Nigerian edible mushroom. The pH of the wastes dropped to 4.0/4.2, 90days after incubation. On the contrary, amino nitrogen content of the wastes increased...

BACKGROUND Lignocellulosic biomass is an attractive renewable resource for future liquid transport fuel. Efficient and cost-effective production of bioethanol from lignocellulosic biomass depends on the development of a suitable pretreatment system. The aim of this study is to investigate a new pretreatment method that is highly efficient and effective for downstream biocatalytic hydrolysis of ...

Thermodynamic data indicate that the oxidation of oxygenated organic species originating from biomass instead water at anode an electrolysis cell should allow decreasing voltage below 1.23 V. Biosourced alcohols, polyols, sugars, lignocellulosic compounds, and their derivatives are then electroreformed to produce clean hydrogen cathode compounds cells. The reported studies highlight main challe...

An effort to utilize solid wastes at dumpsite as refuse-derived fuel (RDF) was carried out. The produced RDF briquette was then utilized in the gasification system. These wastes were initially examined for their physical composition and chemical characteristics. The wastes contained high plastic content of 24.6-44.8%, majority in polyethylene plastic bag form. The plastic wastes were purified b...

In this work, the effects of different fiber loadings on mechanical properties composites at sub-micron scale were studied through nanoindentation followed by physical characterization. The prepared incorporating wheat straw, corn stalk, and rice husk in polypropylene copolymer using a melt processing method thermal–hydraulic compression technique. Nanoindentation experiments quasi-continuous s...

Carbonization is a kind of pyrolysis process to produce char from organic materials under an inert atmosphere. In this work, chars derived from various solid wastes were characterized from the standpoint of fuel recovery and pretreatment of waste before landfilling. Sixteen kinds of municipal and industrial solid wastes such as residential combustible wastes, non-combustible wastes, bulky waste...

The aim of study as to determine the effects some composts on nutritional value Pleurotus pulmonarius (Fr.) Quel. energy, dry matter, moisture, crude protein, fat, ash, organic and nitrogen free extract were 311.3-313.9 (kcal 100 g-1), 91.8-92.5, 7.5-8.2, 27.3-38.6, 1.5-1.9, 5.3-6.4, 35.9-46.8 86.0-87.1 (g g-1) weight, respectively. contents polymeric substance determined 13.6-16.2% cellulose, ...

Several thousands of million tons of wastes are generated worldwide every year. Of these, organic solid wastes have the potential to partially satisfy the production of chemicals, whilst the environmental impact can be minimized and the sustainability of the processes increased compared to those based on fossil resources. However, these wastes are complex due to their high heterogeneity, and ne...

With the increasing of plastics content in solid waste, both municipal and industrial, also increases the interest in its use as an energy source. Some of these wastes are an important potential source of energy and might be valorized using the pyrolysis or gasification processes. However, the presence of high chlorine contents in its composition prevents its management by a thermal process, as...
