Comments Off on Earth Day 2020 goes digital

Earth Day will take a surprising turn this year by relocating to the internet. Due to the global coronavirus pandemic, events for the 50th anniversary of Earth Day on April 22 will be digital. “At Earth Day Network, the health and safety of volunteers and participants in Earth Day events is our top concern,” said Kathleen Rogers, president of Earth Day Network. “Amid the recent outbreak, we encourage people to rise up but to do so safely and responsibly — in many cases, that means using our voices to drive action online rather than in person.” Related: How Earth Day began and how it helps the planet To keep track of the global Earth Day conversation across several digital platforms, participants will use the hashtags #EarthDay2020 and #EarthRise. Interested people can follow Earth Day Network’s social media accounts (@earthdaynetwork) for live coverage. Individuals and groups may also participate in environment-related online teach-ins, virtual protests and social media campaigns. Wisconsin Senator Gaylord Nelson founded Earth Day in 1970 after a devastating oil spill off the Santa Barbara coast. He wanted to capture the energy of the student antiwar movement to shift public awareness and policy around the environment . His coalition originally chose April 22 because it fell between spring break and final exams. At the first Earth Day, 20 million Americans, or 10% of the country’s population at that time, participated in events related to environmental science. “Our current pandemic demonstrates that governments must embrace science early,” Rogers said. “As we see now, many governments were slow to respond or even indifferent about the science of the coronavirus pandemic. But the last few weeks have also demonstrated that our society, even at the international level, is capable of mass shifts across all sectors to meet a crisis head-on. We must apply the same scale and urgency of our response to climate change .” Because the pandemic is affecting regions in different ways, some people might choose in-person gatherings to celebrate Earth Day. People should take precautions and check current guidelines from the World Health Organization before planning or attending gatherings. + Earth Day Image via NASA

Researchers convert durian and jackfruit biowaste into ultracapacitors

Comments Off on Researchers convert durian and jackfruit biowaste into ultracapacitors

Durian fruit is notable for its funky stench, making it a rather malodorous waste when it is discarded. But a new study from Australia’s University of Sydney, published in the Journal of Energy Storage , focused on recycling durian waste into an affordable, sustainable source of energy storage to counteract global warming. How? The researchers have discovered a way to create ultracapacitors from durian and its related jackfruit cousin. Who knew that putrid-smelling biowaste could pack an electrical punch? “Super-capacitors are like energy reservoirs that dole out energy smoothly. They can quickly store large amounts of energy within a small battery-sized device and then supply energy to charge electronic devices, such as mobile phones, tablets and laptops, within a few seconds,” explained associate professor Vincent Gomes. “Using durian and jackfruit purchased from a market, we converted the fruits’ waste portions (biomass) into super-capacitors that can be used to store electricity efficiently.” Related: New technological process transforms everyday trash into graphene As TreeHugger reported, the waste biomass of durian and jackfruit are “converted into a carbon aerogel using non-toxic methods.” These aerogels are then leveraged and converted into electrodes, “which are tested for their energy storage properties.” Interestingly, these durian- and jackfruit-derived electrodes “demonstrate outstanding performance, making them a green, low-cost energy solution for charging phones, laptops and tablets.” When compared to what’s currently on the market, the electrodes developed from durian and jackfruit have proven to be a more energy-efficient alternative to traditional ultracapacitors derived from activated carbon. “The durian and jackfruit super-capacitors perform much better than the materials currently in use and are comparable, if not better, than the expensive and exotic graphene -based materials,” Gomes said. “We have reached a point where we must urgently discover and produce ways to create and store energy using sustainably sourced materials that do not contribute to global warming.” + Journal of Energy Storage Via TreeHugger Image via Jonny Clow

Powerbarn is a bioenergy plant offering power to 84,000 families

Comments Off on Powerbarn is a bioenergy plant offering power to 84,000 families

In the rural commune of Russi in northeast Italy, Italian architecture firm Giovanni Vaccarini Architetti has converted an industrial zone once used for sugar production into the new grounds for the Powerbarn, a bioenergy production plant with a sculptural appearance. Inspired by eco-friendly principles, the architects crafted a masterplan that integrated the architecture into the farming landscape and restored and re-naturalized approximately 280,000 square meters — including three wetlands — for the benefit of the local ecosystem and community. Surrounded by human-made dunes to soften its appearance, the Powerbarn uses biomass, biogas and solar systems to generate an output of approximately 222 GWh a year — enough to satisfy the energy needs of 84,000 families. Once the site for the Eridania sugar factory, the former industrial property has long felt at odds with its agricultural surroundings. That’s why Giovanni Vaccarini Architetti paid special attention to the edges of the property, which the team has redefined with human-made dunes — rather than an industrial fence — constructed only from earth used from the construction site excavation. The vegetated dunes help soften the Powerbarn’s size; the main building that comprises the furnace and smoke line measures about 100 meters in length and over 30 meters in height. Related: Ski atop the world’s cleanest waste-to-energy plant in Copenhagen “Our intention was to create something similar to a natural bastion, almost a dune, along the edge of the area now converted into the pole for energy production — hence an element closely linked to the ecological functions of an environment,” Giovanni Vaccarini explained. “Not a barrier, but a functional element that would express our design intentions: to create a permeable, accessible and living element.” Inspired by the “razzle dazzle” camouflage technique, Vaccarini clad the Powerbarn in large triangular panels of timber and steel that also evoke the art of weaving and nomadic architecture. The masterplan also includes a building for offices, an electric substation and an area for wastewater collection. In addition to solar, the Powerbarn is fueled with wood chips and organic materials sourced within a 70-kilometer radius of the site along with livestock sewage that’s fed into the biogas plant. + Giovanni Vaccarini Architetti Photography by Massimo Crivellari via Giovanni Vaccarini Architetti
