Mineral element profiles of animal wastes and edible tissues from cattle fed animal wastes
… mineral element levels in feedstuffs, animal wastes and tissues from cattle fed broiler litter or cattle waste. Heifers fed 30% broiler litter ensiled with corn forage performed as well as heifers fed corn silage and soybean meal but performance tended to be lower than for heifers fed …

The fixation of arsenic wastes
… of insect and fungicidal pests. Arsenical wastes are also often produced during the extraction of metals such as copper, gold, nickel and tin. Consequently, there are large numbers of sites contaminated with toxic arsenic residues. The environmental treatment of arsenic is complicated by …

Anaerobic digestion of catering wastes
… and biomass retention in digestion of food wastes.<br/><br/>Source segregated food wastes were collected from a university catering facility and found,<br/>in characterisation studies, to have a total solids (TS) content of 28.1±0.25 %, a volatile<br/>solids (VS) content of 95.5±0.06% of TS …

Accelerated carbonation of hazardous wastes
… dioxide, and can be used to treat hazardous wastes and soils and create new construction materials. The present work examines the use of accelerated carbonation to reduce the hazardous properties of wastes as a means of reducing the costs of disposal to landfill, and then develops the process …

The Immobilisation of Radioactive Wastes
… system for low and intermediate level wastes. The desire to improve cement based characteristics is discussed and the technique of incorporating polymers is reviewed. The importance of leaching characteristics is highlighted and methods of measurement are compared. Section 3 describes …

Accelerated carbonation of wastes and minerals
… could be used for the stabilisation of hazardous wastes, remediation of contaminated soils and re-use/recycling of various waste streams. ACT has also potential for storing anthropogenic CO2 emissions into mineral silicates and alkaline waste residues via mineral or waste carbonation. Compared to …

Tower Continuous Fermentation of Cellulosic Wastes
The aim of this work was the study of the direct bioconversion of cellulose to biomass in a novel Tower fermentation system. Ball milled a-cellulose and newspaper were used as model substrates. Five cellulolytic fungi were selected from the literature for their bioconversion abilities. Their …

Geochemical Reactions in Unsaturated Mine Wastes
… to acid mine drainage (AMD). Most of these mine wastes occur as large piles that are open to the atmosphere so that air and water vapor can circulate through them. This study addresses the reactions and transformations of the minerals that occur in humid air in the pore spaces in the waste piles. …

Biological wastes as plant growth substrate amendments
Globally, agriculture is being intensified with mechanization and increased use of synthetic fertilizers and pesticides. There has been a scaling up of production to satisfy the demands of supermarket distribution. Problems associated with intensification of production, trade globalisation and a …

Electrolytic remediation of chromated copper arsenate wastes
… of waters and soils contaminated by process wastes. The active ions in water-based CCA are hexavalent chromium, divalent copper, and pentavalent arsenic. The objective of this study was to develop the underlying engineering science for remediation of aqueous CCA wastes via electrolytic …

Biodegradable food packaging using agricultural wastes (Banana Pseudostem)
Biodegradable food packaging has been developed in this research from banana pseudostem. The research can be divided into three phases. The first phase was to explore the possible method to isolate nanocellulose from banana pseudostem as the main polymer for bioplastic formation. Alkaline …

Cement-based solidification of ferro-alloy solid wastes
… this work due to high levels being found in the wastes and the different mechanisms by which they have been found to interact with cement. Preliminary experiments identified conditions which were conducive to the effective setting of the monolith. Three operational variables were chosen as having …

The decomposition of agricultural cellulosic wastes by coprinus cinereus
This study was part of a larger research programme de signed to obtain a method of improving the feed value of waste straw to ruminants, using a selected microorganism. The work reported here was carried out to assess the potential of Coprinus cinereus (Schaeff ex Fr.) S.F. Gray sensu Konr. for …

An investigation into biological treatment of fruit cannery wastes
… fruit or vegetable being processed. The wastes generally have high BOD or COD concentrations (mainly due to sugars and starches) and low concentrations of the nutrients, nitrogen and phosphorus. In many towns the seasonal 'pollution' load from the canneries can exceed by several times the …
