Cement Production

The environmental impacts of cement production using two pre-drying processes, i.e., coal-fired pre-drying process and pre-drying process by waste heat from kiln tail process were analyzed and compared through life cycle assessment (LCA). The results show that the energy consumption, GWP, AP, POCP, HT and EP of pre-drying process by waste heat from kiln tail are about 1%, 2%, 5.2%, 5% ,3.5% and 3.8% lower than coal-fired process; therefore the application of pre-drying process by waste heat from kiln tail has obvious environmental benefits.

This study represents a cumulative exergy and life cycle assessment of corn ethanol production via dry milling. The process under consideration includes the agricultural process for production of corn, transportation of corn and industrial process of ethanol production. The secondary process of production of pesticides and fertilizers is also taken into consideration. It is seen that the exergy content of ethanol produced from this process is 23.3 MJ per liter of ethanol produced. The non-renewable input was 7.5 MJ per liter. The overall production efficiency of the industrial process was found to be 49%. The life cycle assessment results showed that both the global warming potential and acidification potential are positive which means that the production of corn ethanol via dry milling contributes to the increase of greenhouse gases and acidification.

Abstract Eco-efficiency is a new concept of environmental analysis seeking to improve products, processes and manufacturing materials. The eco-efficiency analysis gives the opportunity to find the most effective solution with the lowest environmental burden in the bottle forming process. For this purpose, the LCA (Life Cycle Assessment) technique of environmental management was used to evaluate selected stages of the bottle forming process. The analysis was carried out using the Eco Indicator 99 method using the SimaPro software.
