Stepwise approach to reduce the costs and environmental impacts
Grinding is a common finishing process to meet specific technological requirements; however, it is energy, resource and time consuming. Thus, the improvement of grinding processes should not only consider the technological requirements but also environmental and economic impacts.

Life Cycle Analysis of Grinding SpringerLink
Life Cycle Inventory provides a basis to evaluate the environmental aspects of unit processes. This paper will provide an integrated analysis of floor-to-floor cycle for product grinding as well as review the state-of-the-art for industrial grinding including cooling lubricants and specific energy. This work discusses existing approaches toThis can be justified by the fact that ceramic tiles are inert, have a long useful life, and are easy to clean, maintain, and generate shallow environmental impacts. This results in a lack of accurate information about the end-of-life scenario for the ceramic tiles, making it challenging to assess the full environmental impact of the product.Life cycle assessment in the ceramic tile industry: a review

Welding, grinding and laser/plasma cutting processes produce huge amounts of fine PM1 particles and various harmful gases that cannot be removed from the indoor air by ventilation alone. Increase production efficiency, reduce your environmental impact and keep your shop and workers safe.Most life cycle assessments of metal production processes do not consider the mining and mineral processing stage in any detail, largely due to a lack of publicly available data and the relatively small contribution that the mining and mineral processing stages make to the ‘cradle-to-gate’ environmental impacts of many metal production Energy and greenhouse gas impacts of mining and mineral processing
