U.N. urges Ethiopia, Egypt and Sudan to recommit to dam talks

The United Nations called on Ethiopia, Sudan and Egypt on Tuesday to recommit to talks on the operation of a giant hydropower dam, urging them to avoid any unilateral action, a day after Ethiopia began filling the dam’s reservoir. The U.N. Security Council will likely discuss the Grand Ethiopian Renaissance Dam (GERD) this week after Arab states requested the 15-member body address the issue.

Recycling contaminants trend up in Nanaimo, well above provincial goals

The Harbour City’s quest to become more green is being thwarted by a blue bin.  Data collected by Recycle BC over the last two years in Nanaimo showed levels of improperly recycled materials and unrecyclable materials finding their way into the curbside blue recycling bins is increasing.  Taaj Daliran, city manager of sanitation and recycling, told Council on Monday, July 6 there is still a great deal of confusion about recycling.  “Some of this contamination is not actually contamination, it’s just mis-recycling. For example, some materials that are supposed to be taken to depots are put in our blue carts.”

10 Ways IoT Fleet Management Can Make Shipping More Sustainable

As we face a global environmental crisis, the fleet industry is coming together to cut emissions. The good news is that the right technology can increase sustainability and improve bottom line at the same time.  Here are ten ways IoT fleet management can make shipping more sustainable while also increasing efficiency and savings.  1. Tracking fuel usage – Tracking fuel usage with IoT fleet management solutions can help companies understand their fuel consumption.  Real-time vehicle tracking can also help fleet managers monitor progress. For example, fleet managers can see how much fuel new sustainability initiatives have saved. It can also give companies up-to-date information for reporting purposes.

UK Film | Sustainability in Action

WE ARE UK FILM brings together the UK’s film national and regional agencies, producers and sales companies under one umbrella to provide clear information about our outstanding locations, services, films and talent.  Moving beyond talk of why film production should be sustainable, experts will discuss specific examples of how the industry is embracing green best practices. This discussion talks to producers, sustainability consultants and production experts who talk about their own hands-on experiences of making film productions more sustainable. We examine best practices across all stages of making a film – development, physical production and post production. Especially as the industry is restarting post-pandemic, how can we build sustainability into every film production as well as every filming facility and studio?

Scientists Create Enzyme That Can Destroy Plastic Within Days, Not Years

Plastic has got to be both a blessing and curse for this planet. However, lately, with the amount of plastic that’s getting accumulated and dumped, it has been causing some serious damage to the environment.  However, it looks like researchers have developed the perfect thing to combat this problem. They’ve developed a cocktail of plastic-eating enzymes which can actually degrade plastic in a matter of days — something that normally takes hundreds of years to degrade. The enzyme cocktail includes PETase and MHETase. These are produced by a type of bacteria that feeds on PET plastic (often found in plastic bottles) dubbed Ideonella Sakaiensis.

Spinning electricity from heat and cold

A new device harvests two types of energy during the daytime, making it cool on one end and hot on the other, to generate electricity around the clock. With further improvements, the device could be used in off-grid Internet-of-things sensors.
The details were published in the journal Science and Technology of Advanced Materials (“Simultaneous harvesting of radiative cooling and solar heating for transverse thermoelectric generation”).
Thermal emission is radiated from the top of the device, keeping it cool, while sunlight is absorbed at the bottom, keeping that part warm. The temperature gradient and types of materials used lead to the generation of a spin current that is converted to thermoelectric voltage. (Image: Ken-ichi Uchida)
