Large areas of land are needed to dispose of wastes produced by mining activities worldwide which poses a myriad of environmental hazards with regards to soil, water and air contamination. This is a problem, especially for a mining country like South Africa, where more than 1500 mines are registered which affects 0.2 million ha of land. Legislation in this country do, however, stipulate that di...

UNLABELLED The preschool that children attend has been shown to be a significant but variable predictor of physical activity of 3- to 5-yr-olds, whereas the time outdoors has been found to be a strong correlate of physical activity. Researchers speculate that variations in preschool physical activity may be attributed to variations in preschool policies and practices, including the form and con...

A high demand for woodchips has encouraged smallholder farmers in Vietnam to invest short-rotation Acacia plantations produce pulpwood that a relatively quick, though often low, income return. Because of an expanding export furniture industry, the Government sought increase sawlog production and, at same time, improve returns farmers. However, currently quality and therefore market value timber...

A revolution of the global energy industry is without an alternative to solving climate crisis. However, renewable sources typically show significant seasonal and daily fluctuations. This paper provides a system concept model decentralized power-to-green methanol plant consisting biomass heating with thermal input 20 MWth. (oxyfuel or air mode), CO2 processing unit (DeOxo reactor MEA absorption...

Formalin is applied in certain aquaculture systems to control parasites infestations as well bacterial and fungal diseases. This study investigated the capacity of end-of-pipe denitrifying woodchip bioreactors remove potentially harmful amounts residual formaldehyde (FA) from effluents. Formaldehyde was readily removed by experimental- field-scale removal FA found be a combination an initial ad...

Organic Rankine cycles (ORC) are efficient technologies for waste heat recovery (WHR) at low to mid temperatures. For the design of ORC power cycles, several thermodynamic parameters should be considered. A challenge related small scale (<50 kW) is define optimal process given frequent variability in a source. Many relevant applications require robust systems perform under varying source loa...

Mechanical mastication is increasingly prescribed for wildfire mitigation, yet little is known about the ecological impacts of this fuels treatment. Mastication shreds trees into woodchips as an alternative to tree thinning and burning the resulting slash, which can create soil disturbances that favor exotic plants. Previous research on mastication has not simultaneously considered both the res...

Moisture absorbency is one of the most important characteristics of rodent beddings for controlling bacterial growth and ammonia production. However, bedding manufacturers rarely provide information on the absorbencies of available materials, and even when they do, absorption values are usually expressed per unit mass of bedding. Since beddings are usually placed into cages to reach a required ...

This paper provides an overview of the trend of generation, composition, and management of municipal solid waste, and estimates the carbon emissions arising from municipal solid waste management in Beijing. The correlation analysis conducted shows that the generation of municipal solid waste in Beijing has been growing steadily, showing high correlations (r > 0.9) to the total GDP, per capita i...
