An environmental impact analysis of grinding
This thesis was intended to investigate the environmental impact of grinding in the United States manufacturing industry. Grinding is an ideal method for producing parts with a fine surface finish and high dimensional accuracy and for shaping hard or brittle workpieces. There are a wide variety of …

Quark masses : an environmental impact statement
We investigate how the requirement that organic chemistry be possible constrains the values of the quark masses. Specifically, we choose a slice through the parameter space of the Standard Model in which quark masses vary so that as many as three quarks play a role in the formation of nuclei, while …

Reducing the Environmental Impact of Wind Turbine Blades
… manufacture, and, furthermore, the turbines are environmentally problematic at end-of-life (EoL), especially the blades. WT blades are mainly made with composite materials comprising thermosetting resin and glass fibre. They are lightweight and strong but problematic to recycle. Large volumes of …

Environmental impact analysis : the identification of secondary impacts
The need for a preliminary environmental impact analysis approach, able to identify secondary impacts, has been revealed by a broad literary review. Therefore, the component interaction technique has been developed which is able to structure a preliminary investigation of secondary impacts. The …

Environmental impact assessment under NEPA: a redundant mechanism?
The National Environmental Policy Act (NEPA) declared the Federal government's commitment to comprehensive environmental protection. The cutting-edge of NEPA is its requirement for including an Environmental Impact Statement (EIS) for all major Federal actions significantly affecting the …
