1. Life Cicle Inventory for Lead Azide Manufacture
ABSTRACT: Like any other manufactured chemical compounds, explosives are produced using chemical reactants and other utilities (steam, heat, compressed air, feed water and electricity) and generate a set of environmental impacts (waste water, solid and water residue and waste heat, for example). On top of that, one can count the intrinsic hazard characterist

2. Análise de ecoeficiência dos óleos vegetais oriundos da soja e palma, visando a produção de biodiesel. / Ecoefficience analysis of vegetable oils from soybeen and palm to produce biodiesel.
O biodiesel é um combustível proveniente de fontes lipídicas renováveis (óleos ou gorduras, vegetais ou animais). Sua obtenção se dá por craqueamento (térmico ou catalítico) ou através das reações de transesterificação ou esterificação. Pela reação de transesterificação, se tem a reação de um triglicerídeo com um alcool de cadeia curt

3. Análise de ecoeficiência: avaliação do desempenho econômico-ambiental do biodiesel e petrodiesel. / Eco-efficiency analysis: environmental-economic assessment of biodiesel and petrodiesel.
Biodiesel is the most likely alternative to petrodiesel. It is composed of methyl or ethyl esters from fatty acids, obtained by a transesterification reaction between any triglycerides and an alcohol with short chain, methanol or ethanol. It has almost the same properties of petrodiesel, but comparing with this, it can eliminate the sulfur oxides emissions a

4. Analise do impacto ambiental do processo de produção de hidrogenio / Hydrogen production process environmental impact assessment
The concern with sustainable development has been taking to a constant improvement in the environmental management tools. Life cycle assessment (LCA) is a process, product or activity processes environmental impacts evaluation method using energy, material consumption and waste environmental releases. LCA is four steps constituted: goal definition and scope,
