Mountaintop Removal Threatens Traditional Blackfoot Territory

2/7/2021

0 Comments

 
The Rocky Mountains that lie within Blackfoot traditional territory are threatened with mountaintop removal. The Grassy Mountain coal project in Alberta, Canada, is slated to begin coal extraction in fall 2021. It is expected to be profitable for only 25 years. However, by then the almost 4,000-acre project will have blasted the terrain with explosives, separating the substrata from the coal and creating a new rock-scape the size of almost 3,000 American football fields.  Places where mountaintop coal removal occurs are never the same; just look at West Virginia, where mountain areas once rich with biodiverse forests have been reduced to barren desolation. And, as my grandmother taught me, disturbed areas are not places to practice Blackfoot traditional knowledge. - - High Country News Perspective

Better Disposable Coffee Cups

1/11/2021

Sugar cane contains around 10% sugar and around 90% non-sugar, the material known as bagasse which remains once the cane has been pulverised and the sugar-bearing juice squeezed out of it. World production of cane sugar was 185m tonnes in 2017. That results in a lot of bagasse which at the moment is often burned. Often, it fuels local generators that power the mills, so it is not wasted, but Zhu Hongli, a mechanical engineer at Northeastern University in Boston, thinks it can be put to better use. As she and her colleagues describe, with a bit of tweaking bagasse makes an excellent—and biodegradable—replacement for the plastic used for disposable food containers such as coffee cups. - Forbes and Northeastern University

A Recycling Plan to Clear Wind Turbine Blades From Graveyards

1/5/2021

It’s difficult to recycle a gigantic wind turbine. The blades are built to withstand extreme weather, from scorching desert heat to hurricane-like winds, and that means their life almost always ends in a landfill. In Europe alone, about 3,800 blades will be removed every year through at least 2022, according to BloombergNEF, as the oldest turbines reach retirement age.  Now a Danish startup has found a way to crush these blades, turning an ultra-resistant mix of fiberglass and industrial glue into barriers designed to block noise from highways and factories. Copenhagen-based Miljoskarm can grind the blades into small pieces of 1 to 2 centimeters with the same type of machines used in auto junkyards. The material is then placed in recycled plastic cases that block noise at least at the same level as barriers made from aluminum and mineral wool, with less maintenance required. - Bloomberg Green
