Selection of hydrothermal pre-treatment conditions of waste sludge destruction using multicriteria decision-making

Article Abstract:

An investigation on the effectiveness of hydrothermal treatment for the destruction of the organic content of sludge waste is presented. The results indicate that hydrothermal treatment proceeds through hydrolysis, resulting in the production of dissolved organic products followed by (COD) removal through oxidation.

Multicriteria evaluation of simulated logging scenarios in a tropical rain forest

Article Abstract:

Forest growth models are useful tools for investigating the long-term impacts of logging. A study done on these models reveal that high cutting limits or low logging intensities cannot compensate for high level of damage caused by conventional logging techniques.
