Composting is clearly reported as one of the most effective technique to transform organic wastes into an interesting resource, useful to improve soil characteristics and playing a potential role in reducing greenhouse gases, due to its high content in stable organic matter (Favoino and Hogg, 2008). However, its agronomical properties are dependent on several factors, which pollutant contents b...

The environmental loading of steroid hormones contained in dairy wastes may cause an adverse effect on aquatic species. To better assess the potential risks of hormone contamination resulting from land application of dairy wastes, various steroid hormones were determined in a typical dairy waste disposalsystem.Quantitativemethodsusinggaschromatography/ mass spectrometry (GC/MS) were developed t...

Lignocellulosic wastes are generally produced in huge amounts worldwide. Peach waste of these obtained from fruit juice industry was utilized as the substrate for laccase production by Pleurotus eryngii under solid state bioprocessing (SSB). Its chemical composition was determined and this bioprocess was carried out under stationary conditions at 28 °C. The effects of different compounds; coppe...

The present study describes the development of a new bioadsorbent from lignocellulosic wastes of agricultural origin. The biosorption capacity of an agricultural solid waste, pine bark (Pinus densiflora Sieb.), to remove phenolic compounds (phenol, 2-chlorophenol (2-CPh), and 4chlorophenol (4-CPh)) from aqueous solutions under batch equilibrium conditions was investigated. The morphological cha...

Management of municipal solid wastes (MSW) in most developed societies now involves the use of thermo-chemical conversion methods. This leads to energy and material recovery while also protecting the environment. However, till date most of the wastes generated in Nigeria (including plastic wastes) are either land-filled or openly burnt. These methods are not sustainable and environmentally non-...

Innovative green technologies are of importance for converting plant wastes into renewable sources for materials, chemicals and energy. However, recycling agricultural and forestry wastes is a challenge. A solution may be found in the forest. Saprotrophic white-rot fungi are able to convert dead plants into consumable carbon sources. Specialized fungal enzymes can be utilized for breaking down ...

As pressure for new infrastructure and development grows, it is inevitable that building projects will encounter some of the c20,000 closed former solid waste landfills in the UK, many of which will have accepted municipal solid wastes (MSW). Construction on or across these sites brings a special set of geohazards associated with the potential for large and difficult to predict settlements, gas...

OPINION: [*6] Per Curiam: The Hazardous and Solid Waste Amendments of 1984 instituted a ban on the land disposal of classes of hazardous wastes unless certain conditions are met. Those amendments require the Environmental Protection Agency to follow a phased schedule for implementing the ban. In this case we consider various challenges to regulations implementing the final portion of this progr...

the effect of acid-alkaline treatment of lignocellulosic material (wild carob forest wastes) on ethyl violet adsorption was investigated. it was found that surface chemistry plays an important role in ethyl violet (ev) adsorption. hcl treatment produces more active acidic surface groups such as carboxylic and lactone, resulting in an increase in the adsorption of ev dye. the adsorption efficien...
