Phenol is an important raw material in many branches of industry (petrochemical pharmaceutical plastic and pesticidal chemical industry ). This research study on phenol production processes by using two different phenol production processes which are cumene oxidation (the Hock process) and toluene oxidation (the Dow process). In order to study in environmental impacts Life Cycle Assessment (LCA) is applied to evaluate environmental impacts of phenol production processes. Environmental impacts are evaluated according to cradle-to-gate approach by using SimaPro 7.1 software for Life Cycle Assessment . Approach by IMPACT 2002+ . The result shows that cumene process is more environmentally favorable than toluene process.

Activated carbon also called activated charcoal or activated coal is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions. In this research studies environmental impacts of activated carbon production processes which produced from two types of agricultural by-products namely : coconut shells and palm-oil shells . SimaPro software is applied to evaluate the environmental impacts of both processes. The results have shown that the environmental impacts for the process using coconut shells as raw material is higher than that using palm –oil shells as raw material.
