Remediation of contaminated land and solutions with binders derived from waste material.
… the soil thoroughly mixed with 0.1g stabilising material was transferred into a 100ml polypropylene container to which 50ml of de-ionised (DI) water or 50 ml of 0.1M HNO[3] or 0.01M HNO[3] was added. The mixture was shaken on a flat bed shaker for 2 hours, and then filtered using a Whatman No 542 …

Numerical modelling of leachate production and movement within landfill sites
… models simplify the actual flow process in the waste matrix and assume the same density throughout the simulation period. Moisture flow through waste material is investigated through experiments, and as a result different mathematical models were developed. These models represent the effect of …

The use of natural site derived materials as concrete aggregate.
… thesis focuses on the use of site-derived fine material, in its natural form, as aggregate in concrete construction. It is proposed that the utilisation of this type of concrete aggregate will lead to; the preservation of natural materials that would otherwise have to be beneficiated off site, …

The utilization of peanut hulls as liquid adsorbent chars
… the plante processing the nuts or discarded as waste material. Similar cellulosic wastes have been profitably utilized in the past as activated ohars. It was the purpose of this work to determine the conditions by which peanut hulls could be converted to liquid adsorbent chars.

Lactic Acid Production Using Sweet Potato Processing Waste
<p>Organic waste generated from industrial sweet potato canning is estimated to be 30% of incoming raw material. This waste contains carbohydrates (sugars and starch) that could be used as substrates for the production of useful compounds via fermentation (e.g. lactic acid), resulting in the …

Predictions of leachate generation from minerals processing waste deposits
… in South Africa produces significant tonnages of waste material which are disposed of commonly in dedicated waste depositories. These deposits pose a potential to pollute the environment if leachate is generated within the deposit and released to the surroundings. Leachate generation is generally …

Fermentation, utilization and palatability of broiler litter ensiled at different moisture levels and with high moisture corn grain
The feasibility of ensiling broiler litter alone, with added water or with high moisture corn grain was evaluated. Wood shaving based broiler litter was ensiled in small laboratory silos (about 4 liters) at moisture levels of 15.6 (no water added), 20, 30, 40 and 50%. Maximum fermentation was …

Revaluing waste in New York City : planning for small-scale compost
One-third of the municipal solid waste stream is organic material that, when processed in landfills, produces methane, a highly potent greenhouse gas. Composting is a proven strategy for organic waste management, which also creates a nutrient-rich soil amendment. This thesis begins with a review of …
