D ozens of emerging technologies for almost every facet of oil sands production could be paving the way for solutions to the most significant environmental and operational challenges faced today. In fact, according to a study by the Canadian Energy Research Institute (CERI), these emerging technologies are establishing a foundation for the industry to reduce …
Excavators: An excavator is a piece of hydraulic equipment that is used to dig and excavate materials that are deep in the earth. The excavator is a popular piece of equipment on typical construction sites, particularly when laying foundation for houses. However, for quarrying, the high-capacity excavators are key in unearthing and digging out raw materials that are …

As a coastal geomorphologist working in the Arctic, I study the impact of climate change on the coasts of Greenland. Shortly after having published a study in Nature 1 showing that Greenland coasts are expanding in …
reduce negative impacts. Sand mining should be done in a way that limits environmental damage during exploitation and restores the land after mining operations are completed. Keywords: resilience; sand market; sand exploitation; environmental impacts 1. Introduction Sand is a natural aggregate formed by rock erosion over thousands of years [1,2].
In the case of sand mining, urgent actions are needed for (1) applying or extending available national regulations and limitations to curb irresponsible and illegal extraction for sand, (2 ...
Natural aggregates, such as sand and gravel, are today the most mined minerals in the marine environment. When it comes to ocean sand there are very different scales of extraction. On one hand, you have a highly …
