Recent scientific data indicate that nanotechnology has the potential to positively impact the agrifood sector, minimizing adverse problems of agricultural practices on environment and human health, improving food security and productivity (as required by the predicted rise in global population), while promoting social and economic equity. In this context, we select and report on recent trends ...

At present, there is growing interest in using low cost, commercially available materials for the adsorption of heavy metals. The major advantages of adsorption technologies are its effectiveness in reducing the concentration of heavy metal ions to very low levels and the use of inexpensive adsorbent materials. In this review, agricultural and forest waste adsorbents were used to remove Pb ions...

Improper management of hospital waste has been reported to be responsible for several acute outbreaks like the severe acute respiratory syndrome (SARS). In spite of these challenges, hospital wastes are sometimes not properly handled in Nigeria. To date, there has not been an adequate study on the effect and fate of burnt hospital waste on agricultural soil. The effect of burnt hospital wastes ...

The purpose of this study was to utilize low quality date syrup, a rich and available source of nutrient in Iran, for the production of bacterial cellulose using Gluconacetobacter xylinus. Static batch fermentationfor the purpose of cellulose production by G. xylinus (PTCC, 1734) was studied using low quality date syrupand sucrose solution (Bx. 10%) as fermentation media at 28°C. Re...

The present work represents potential bio-sorbents: Tilia cordata (little leaf linden) and Foeniculum vulgare (fennel). copper removal was operated in batch procedure. Adsorbent mass, ion concentration, pH, time, temperature considerations were inspected. highly beneficial provisions for adsorption are 10 mg /L as preliminary 0.2 g mass pH 5.5 5.23 vulgare. Adsorption statistics follow the Lang...

Accumulation of environmentally hazardous agricultural waste, in particular cow manure without the proper treatment, creates an ecological threat to environment. During energy crisis, search for alternative pathways obtain is also one most urgent issues today. Cow promising as a substrate anaerobic fermentation with production valuable carrier — methane. Fermentation sole not spread. It takes p...

Anaerobic digestion of source-separated municipal organic waste is considered feasible in Denmark. The limited hydraulic retention in the biogas reactor (typically 15 d) does not allow full degradation of the organic waste. Storage of anaerobically digested municipal organic waste can therefore be a source of methane (CH4) emission that may contribute significantly to the potential global warmi...

The current production status of building ceramics is based on the following realities. First, due to market conditions, number factories in operation has decreased significantly. Second, from 2019, taking into account pace housing construction related transition new financing mechanisms, ceramic bricks increased by 2-3% 2019. Growth opportunities are associated with an increase thermal efficie...

One of the greatest challenges facing most urban centers in Nigeria today is how to cope with the increasing volume of solid wastes being generated daily by its populace. Municipal solid waste tend to be one of the most visible and serious environmental problems in Nigerian cities [1]. This is manifested by large refuse heaps which dot most carriageways, streets and surroundings disfiguring the...
