Research from the University of Tokyo’s Institute of Industrial Science has revealed that discarded concrete can be strengthened with the addition of wood waste. This pioneering technique promises to be an environmentally friendly way to enhance concrete structures while simultaneously reducing construction costs and curtailing carbon emissions . It is hoped that this groundbreaking new method will help make better use of old concrete and any waste plant or wood materials. With traditional methods, reusing old concrete is unfeasible. The research team’s first author, Li Liang, explained, “Just reusing the aggregate from old concrete is unsustainable, because it is the production of new cement that is driving climate change emissions.” The team, therefore, sought to find a better approach, particularly one that would “help promote the circular economy of concrete,” according to the University of Tokyo. Related: 11 green building materials that are way better than concrete The innovative process involves taking discarded concrete and grinding it into a powder. Wood waste is also sourced from sawdust, scrap wood and other agricultural waste. Rather than sending this wood off to landfills, it is instead leveraged in the concrete recycling process for the key ingredient, lignin. Lignin is an organic polymer that comprises wood’s vascularized tissue and accounts for wood’s rigidity. The concrete, now in powder form, is then combined with water and the lignin to form a mixture. This mixture is both heated and pressurized, allowing for the lignin to become an adhesive that fills the gaps between the concrete particles. What results is a newly formed concrete with stronger malleability than the original concrete. Additionally, the lignin makes this new, recycled concrete more biodegradable . “Most of the recycled products we made exhibited better bending strength than that of ordinary concrete,” said Yuya Sakai, team lead and senior author of the study. “These findings can promote a move toward a greener, more economical construction industry that not only reduces the stores of waste concrete and wood , but also helps address the issue of climate change .” + The University of Tokyo’s Institute of Industrial Science Via New Atlas Image via Philipp Dümcke

Filed under Business, Eco, Green

London-based architect Margot Krasojevic has just unveiled a futuristic art gallery that runs on hydroelectric power. Slated for the coastal Russian region of Sochi, the Hydroelectric Sculpture Gallery will harness enough wave energy to not only be 100% self-sufficient, but it will also be able to channel surplus energy back into the grid, powering around 200 nearby houses and businesses as a result. The art gallery will be located on Sochi’s coastline, where it will use the exceptionally strong coastal swells from the Black Sea to power a water turbine system . Krasojevic’s vision depicts a sculptural volume that rises out of an existing wooden promenade. The building, which will be partly submerged into the sea, will be strategically angled at 45 degrees to the coastline for maximum wave exposure. Related: Oil rig off South Korea’s coast to become a floating hotel that operates on tidal energy According to the design plans, the building will “use the environment’s characteristics to generate clean, sustainable energy, without affecting the quality and nature of the landscape.” State-of-the-art engineering will allow the structure to harvest wave energy through oscillating water columns as the waves crash against it. Generating up to 300kW, the system will enable the gallery to operate completely off the grid and channel surplus energy back into the grid. It could supply clean energy to approximately 200 households and businesses in the same area. Visitors to the futuristic gallery will enter through a long walkway stretching out from the shore. The robust exterior of the building will comprise various walkways and ramps that wind around the steel structure. Sinuous volumes will conceal the building’s many turbines, which will also be partially submerged underwater. Inside, the spaces will reflect the building’s functions. The various galleries will be laid out into a power plant format, with steel clad ceilings that mimic the rolling waves that crash into the exterior. Irregularly shaped skylights will also create a vibrant, kaleidoscope show of shadow and light throughout the day. + Margot Krasojevic Images via Margot Krasojevic

Comments Off on 12 surprising things that arent vegan

It’s hard to stick to a vegan lifestyle. It can be easy to be foiled by ingredients that just slip right by you, and these aren’t just in food . A surprising number of non-food items also contain animal-derived ingredients. What’s a wannabe vegan to do? Remember that drastically cutting down on animal consumption is good for the planet, even if you fall short of 100 percent. If you want to be as close to completely vegan as possible, here’s a list of some surprising foods and other items that aren’t necessarily vegan. Sugar The sugar industry uses bone char from slaughtered cattle to remove the color from sugar so it becomes a lovely, bright white. What about using brown sugar? Unfortunately, that’s made of white sugar with molasses added to it. If you want to avoid bone char-processed sugar, buy organic, unrefined, beet or coconut sugar. You can also consult PETA’s list of manufacturers that forego the bones. Condoms Many condom manufacturers use the milk derivative casein for a smooth feel. If you can do without that texture, check out vegan-friendly brands . Altoids Would you like some tendons with your fresh breath? Yep, those ubiquitous mints contain gelatin. Time for a Tic Tac instead, or opt for the Altoids labeled “sugar-free smalls,” which do not contain gelatin. Related: 10 vegan myths, debunked Tattoo ink Charcoal can be made from plant or animal origins. But many of the black dyes used in tattooing are made with charcoal derived from animal bones. Other non-vegan ingredients in tattoo ink are glycerin (from animal fat), gelatin and shellac (made from crushed beetles). If vegan ink is important to you, consult this international list of vegan-friendly tattoo artists . Apple juice Now, it’s time for something really gross. Some companies use isinglass, or fish bladders, to clarify their apple juice. Paintballs Animal tendons and sinews find their way into a lot of food and non-food products. The outer layers of paintball capsules are usually made of gelatin. Dryer sheets Dryer sheets are designed to fight static electricity and make clothes soft and lint-resistant. But what keeps the sheets from drying out? In some cases, animal fat. Urban Vegan assembled a list of vegan alternatives , if you happen to use dryer sheets. Alternatively, you can also reduce your waste by opting to use wool dryer balls. Paint and makeup brushes Artists and anybody who uses makeup might wonder, where did the hairs in my brush come from? They might be synthetic, or they might be from some poor pig, squirrel, sable or Siberian weasel. Artists, consult this list of cruelty-free brushes , and here’s a list of vegan makeup brushes . Related: The pros and cons of going vegan Crayons In other art supply news, crayons contain stearic acid. This ingredient occurs naturally in plants and animals. But it’s often animal-derived, a slaughterhouse byproduct. Crayons are one of many products that contain stearic acid, including soaps, cosmetics, candles, lubricants, chewing gum and hairspray. If you prefer your crayons vegan, check out these triangular ones made by Melissa and Doug . Worcestershire sauce Newer vegans might not have realized this yet, but traditional Worcestershire sauce contains anchovies. Instead, make your own or buy this vegan, organic Worcestershire sauce from trusted brand, Annie’s. Soy cheese If you’re vegan, you probably already know that many regular cheeses aren’t even vegetarian, because they contain rennet, enzymes produced in bovine stomachs that help cheese curdle. But did you know many soy cheeses aren’t vegan? They often contain casein, which seems really weird, because why would you even want soy cheese if you weren’t vegan? British money Vegans who live in or are visiting Britain aren’t thrilled to handle the £5 notes, which contain tallow, an animal fat derivative. It is used to make the bills anti-static and less slippery. British vegans and vegetarians have been protesting since the new notes were introduced in 2016. This month, a British employment judge ruled that the Equality Act should also apply to people who sincerely believe in ethical veganism. How an indirect discrimination case will affect the bank notes is still to be seen. Plastic bags Could be beef tallow, could be chicken fat — most plastic bags use some type of animal fat as “slip agents” to prevent bags from sticking together.

Half a billion Australian animals, even 30% of koala population, likely lost to wildfires

Comments Off on Half a billion Australian animals, even 30% of koala population, likely lost to wildfires

Record-breaking wildfires have ravaged millions of Australian acres for many months now. Ecologists estimate upward of 480 million mammals, birds, reptiles, amphibians and insects have died, as well as more than 8,000 koalas from New South Wales, equating to over 30% of the region’s entire koala population. Figures continue to rise as the fires rage on. Heat from the fires has driven many animals, such as kangaroos, to flee. But not all can escape, exemplified by flightless endemic birds unable to venture far from the ground. The plight is worse for koalas, already a vulnerable species experiencing significant habitat loss . Koalas are slow-moving by nature, incapable of escaping highly flammable eucalyptus trees. The flames will need to subside further before their losses can be fully assessed. Related: Koala-sniffing detection dog, Bear, helps save koalas from Australian bushfires Other species have been devastated as well. Insects, vital to pollination and nutrient cycles, have suffered massively. Many rare plants are also feared to be entirely decimated, with no chance of recovery for their species. These staggering losses jeopardize species populations and ecosystems in Australia. Environmental activists are consequently sounding alarms on climate change , demanding halts to logging and coal use due to their exacerbation of wildfire conditions. “The compelling issue here is climate change. Yes, Australia is burning, and national parks and our native animals are being decimated,” said Clover Moore, mayor of Sydney. “As the driest continent on Earth, we’re at the forefront of accelerating global warming . What is happening is a wake-up call for our governments to start making effective contributions to reducing global emissions.” Various animal care facilities are struggling to help the surviving animals. Eventually, once they have healed, these animals still need to return to their natural habitats. The surviving animals may have trouble finding food and shelter in the blazes’ aftermath. “We’re getting a lot of lessons out of this, and it’s just showing how unprepared we are,” said Kellie Leigh, executive director of Science for Wildlife, to the Australian parliament during an urgent December hearing regarding the koala population. “There’s no procedures or protocols in place — even wildlife carers don’t have protocols for when they can go in after the fire.” Typically, wildlife authorities advise against feeding wild animals . But the ravaging wildfires have prompted a message change — people are now encouraged to provide crucial food and water to wildlife in affected areas. Lands affected range from at least 8.9 million acres in New South Wales, 2.9 million acres in Western Australia, 1.8 million acres in Victoria, 618,000 acres in Queensland and 250,000 acres in South Australia.

Ice rink alternatives and their environmental impact

Comments Off on Ice rink alternatives and their environmental impact

Ice rinks are an important fixture of winter sports, whether for ice hockey, speed skating, curling, ice dancing or figure skating. But with growing concerns about global warming , water scarcity and our planet’s climate crisis , even the International Olympic Committee (IOC), the International Ice Hockey Federation (IIHF) and the National Hockey League (NHL) have been considering the environmental issues related to coordinating ice sports events and ensuring energy consumption and rink-operating costs are feasible. As a result, there is now a movement towards utilizing synthetic ice on ice rinks. The first historical mention of a skating club’s founding was in 1642 in Edinburgh, Scotland. As skating clubs grew, they inspired inventors to create artificial ice surfaces, so the rink would not be at the whim of the weather. By 1843, a Punch magazine article featured the first artificial ice rink, “not of frozen water but of a slush of chemicals including hog’s lard and melted sulphur, which smelled abominably.” That was followed by the growing popularity of ice hockey from the 1880s onward, which increased the demand for more rink construction. When the 1890s rolled around, the rush to patent ice rink surfaces began and has not abated since. Related: 5 sustainable activities to make the most of a winter wonderland Rinks have long required both ice-making technical equipment and ice maintenance measures. Unfortunately, contemporary ice-making and maintenance technologies consume large amounts of energy and produce refrigerant gases that cause pollution , making them environmentally harmful. During the most recent determination of the NHL’s total carbon footprint , it was estimated to emit 530,000 metric tons of greenhouse gases , an amount rivaling the yearly emissions from 110,000 cars, says the Environmental Protection Agency (EPA).  Which refrigerant gases are linked to present-day ice rinks? The main refrigerants associated with most ice-making equipment include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), hydrocarbons, ammonia and carbon dioxide. CFCs and HCFCs are synthetic gases attributed to ozone layer destruction. HFCs heighten the greenhouse effect, while carbon dioxide similarly intensifies global warming. Plus, ammonia, when inhaled, aggressively causes irreversible respiratory damage. And hydrocarbons, like propane and isobutane, are highly combustible, often exacerbating smog formation. Hence, each of these gases adversely affects the environment.  Of course, as ice rink technology advances, many refrigerants are under a phase-out schedule, especially in Canada, due to the Montreal Protocol terms. Additionally, Canadian Consulting Engineer magazine reported: “Since 2010, no new HCFCs equipment have been manufactured in Canada or imported,” though extant ones are still in use today. Even with ammonia and carbon dioxide as the main refrigerants of choice for the majority of today’s ice rinks, they still have their attendant issues as well. For example, whereas ammonia may be a primary refrigerant, it is often utilized concurrently with brine to keep the rinks cold. The brine entails that this secondary fluid is high in salinity, having had salt added to boost its cooling properties. This highly saline secondary fluid, if leaked, can pose serious environmental damage. Meanwhile, despite “some rinks add[ing] ordinary salt to the water to keep them from freezing,” Wondergy documents, “most modern rinks now add ethylene glycol.” Ethylene glycol is a type of antifreeze, and it is highly toxic . Again, its leakage would be harmful to the environment, poisoning living organisms, their habitats and ecosystems . Other negative impacts of ice rinks include greenhouse gas emissions of carbon dioxide. For instance, CO2Meter reported that to shift away from coolants like HFCs and other fluorinated gases, some ice rinks have been using carbon dioxide-based refrigeration systems as their primary refrigerant. Carbon dioxide is a better alternative, though its use still contributes to global warming. Likewise, the Environmental Protection Agency (EPA) has cataloged that other noxious emissions, such as high nitrogen dioxide levels and carbon monoxide, are being released by indoor ice rinks due to ice resurfacers, such as Zamboni rink vehicles. The EPA website states, “In enclosed ice arenas, a primary source of indoor air concerns is the release of combustion pollutants such as carbon monoxide (CO), nitrogen dioxide (NO2) and particulate matter (PM) into the indoor air from the exhaust of fuel-fired ice resurfacers.” This assertion is supported by an Environmental Defense Fund (EDF) study , which shares that “nearly 40% of the rinks surveyed worldwide could be exceeding the World Health Organization’s 1-hour exposure guideline value for nitrogen dioxide in indoor air, with higher percentages of rinks exceeding this value in the US (55%) and Canada (46%). High nitrogen dioxide levels have been associated with respiratory problems such as severe coughs, chest pain and pulmonary edema.” Additionally, the same EDF study addresses carbon monoxide risks from ice rinks, citing that “High carbon monoxide levels can cause headaches, dizziness, nausea and impaired performance. At the levels of carbon monoxide typically found in indoor rinks, fast breathing from skating or hockey can produce adverse health effects.” The combination of ice-making, ice-maintenance and ice-resurfacing factors pose harmful health consequences for those who frequent ice arenas and rinks. For these reasons, ice arenas and rinks are turning to synthetic ice as an alternative. Xtraice, a company known for building and distributing synthetic ice for rinks, says that synthetic ice’s significant advantages are that it doesn’t use water and thus doesn’t waste energy on ice-making or ice-maintenance. Rather, it eliminates the cost of water and electricity that traditional ice rinks contend with. Besides, a synthetic ice rink can be used 24/7 without having to be re-surfaced in the same way real ice does. Xtraice explains further that synthetic ice rinks “are cleaner and do not require big noisy generators and best of all, they do not emit CO2 into the atmosphere.” What’s the catch? Synthetic ice is mainly composed of high-density polyethylene panels. Polyethylene is the most common plastic on the market. Critics of plastic ice worry about the environmental implications of the microplastics that could be released as skates erode the synthetic ice surface and create shavings and abrasions, which, when brushed or cleaned off of the rink, would likely be dumped in the refuse bin. From there, they could find their way into waterways and oceans , polluting the environment. Accordingly, ice rinks can be viewed as a sustainability conundrum, at least for the time being. Traditional ice rinks have noise, energy waste and pollution costs. And their alternative, the synthetic ice rink, while resolving those issues, still generate other environmental concerns surrounding microplastic and plastic detriments. Only time will tell how the ice rink will evolve to become more eco-friendly. Via Xtraice and New York Times Images via Jimmy Chan , Suzy Hazelwood , Pixabay , and Lina Kivaka

Comments Off on BIG plans unveiled for pedestrian paradise in Downtown Brooklyn

After nearly a year of research, Bjarke Ingels Group (BIG) and WXY Studio have unveiled their visions for improving Downtown Brooklyn — a 370-acre urban district with updated streetscapes, plazas, and public spaces. Commissioned by the Downtown Brooklyn Partnership, the Downtown Brooklyn Public Realm Vision includes a comprehensive study of the urban district’s existing conditions as well as a bold, long-term design vision for making the area more inclusive, inviting, and safer for pedestrians and cyclists. The Downtown Brooklyn Public Realm Vision was created in response to Downtown Brooklyn’s unprecedented growth over the last fifteen years since its 2004 rezoning. The Downtown Brooklyn Partnership tapped WXY Studio and BIG, who worked in collaboration with Mathews Nielsen Landscape Architects and Sam Schwartz Engineering, to create a comprehensive study and implementation plan. This plan is intended to help unify the growing mixed-use area and meet the needs of the diverse community, which is expected to welcome 50,000 additional residents by 2025. “The Plan draws upon the District’s existing conditions, systems, land uses and policies to create a bold design vision that is uniquely Brooklyn, provides a greener, safer pedestrian and bicycle experience, and unlocks projects, initiatives and pilots for a more vibrant public realm,” BIG explained in a project statement. “Downtown Brooklyn Public realm is re-animated into a playful environment largely focused on the pedestrian experience. A place where residents, workers and visitors can enjoy gathering outdoors, practice sports and celebrate the diverse culture of Downtown Brooklyn.” Related: Reclaimed NYC water towers are upcycled into a NEST playscape in Brooklyn To visually unify the updated streetscapes, the architects have proposed a distinct yellow-orange color palette for the mixed-use area that will be applied to the bike paths, street furniture, and planters.

Comments Off on Cartoon-inspired prefab treehouse can grow taller and wider over time

Design practice Studio Precht teamed up with tiny-house startup Baumbau to design Bert, a tiny modular treehouse that’s expected to hit the market in spring 2020. Inspired by the Minion films, the playful periscope-like structures eschew hard angles and offer a livable and cozy environment with a minimal footprint and off-grid capabilities, including built-in solar and a water treatment facility. Designed as a reaction to Bauhaus -style buildings found in cities worldwide, Bert embraces diversity and natural materials rather than cold concrete and steel. Built with a wood structure with fabric-lined interiors, the Bert treehouse mimics the shape of a tree, from its rounded trunk-like body to its brown leaf-like shingles on the facade that help camouflage the building into the surroundings. Large glass openings immerse users in the forest. As a modular structure, all parts of Bert will be prefabricated in a factory and assembled on site to reduce landscape impact. Related: Futuristic treehouse in Arkansas is designed to inspire imagination “We are fully aware that architecture is this serious and profound craft with a long culture and tradition,” says the design team in a press statement. “You see that when we architects find reference for our projects in art, philosophy, literature or nature. For this project, we also looked at art to find reference. But not at Michelangelo or Dali. Rather we looked at cartoon characters of Sesame Street or Minions. We took a playful look at this project and wanted to create a rather unique character than a conventional building. A quirky looking character that becomes part of the wildlife of a forest. I think this quirkiness can create feelings and emotions. And maybe these are attributes in architecture that are missing these days.” Modeled after a tiny home, Bert offers all the basic necessities within four floors. The entrance and living space is located on the ground floor, a bedroom and sitting area on the second floor, the kitchen and dining area with a secondary bedroom on the third floor, and the bathroom on the top floor. As a modular structure, the Bert treehouse can be customized to the buyer’s specifications to “grow” taller and wider with new modules, making it an ideal choice for eco-hotel operators. The smallest Bert structure starts at 120.000€ ($136,313 USD) and is expected to hit the market early next year. + Studio Precht Images via Percht

Comments Off on This multigenerational smart home boasts energy savings

When a family approached international design practice ONG&ONG to design a home for accommodating multigenerational needs, the firm responded with a contemporary abode that not only caters to residents of different ages, but also boasts a reduced carbon footprint. Located in Singapore, the 37FC House is carefully laid out to make the most of its long and linear plot and to optimize exposure for its rooftop solar panels. In addition to other energy saving systems such as home automation , the multigenerational home is estimated to save 30 percent on energy costs as compared to similarly sized homes. The strikingly contemporary 37FC House stands out from its neighbors with its boxy form spread out across four levels to maximize living space on a narrow lot. Deep overhangs protect the interior from Singapore’s intense heat, while an abundance of greenery planted around the perimeter and on every floor of the house help cultivate a cooling microclimate and provide a sense of privacy for the residents. Retractable full-height glazing creates a seamless indoor/outdoor living experience, while the generous use of teak throughout the home further emphasizes the connection with nature. Related: Singapore’s energy-efficient green heart center Spanning an area of 5,800 square feet, the 37FC House includes four bedrooms across four floors, including the basement and attic. The main service areas and communal spaces are located on the ground floor that opens up to a lushly planted rear garden, where a Sukabumi-tiled lap pool is located. With approximately 1.5 times more floor space than the ground volume, the second floor cantilevers over the ground floor and contains two junior suites in the rear and the master bedroom that opens up to views of the street and garden. The attic houses a guest bedroom, while the basement includes an additional living room. A sky-lit black steel staircase and an elevator join the home’s four floors.  To reduce energy consumption, the home is powered with solar energy. Home automation that can be remotely controlled with a smartphone — such as the EIB system for controlling lighting — also helps with energy savings. + ONG&ONG Images by Derek Swalwell
