Comments Off on Loophole allows 1M tons of sludge to be dumped on Great Barrier Reef

The world’s largest coral reef is facing a major sludge crisis. Australia’s Great Barrier Reef Marine Park Authority just approved the dumping of one million tons of sludge on the delicate reef system thanks to a loophole in the country’s law. Marine officials say that port industries have the right to dump waste that is dredged from the ocean floor wherever they want, including over the Great Barrier Reef . Environmentalists are concerned that the sludge will “smother” the reef and are looking to dump the waste elsewhere. Related: University of Queensland wants to drop “bommies” on the Great Barrier Reef “The last thing the reef needs is more sludge dumped on it, after being slammed by the floods recently,” Larissa Waters, co-head of the Greens Party, explained. “One million tons of dumping dredged sludge into world heritage waters treats our reef like a rubbish tip.” According to  BBC , Waters warned that if the sludge is dumped directly over the reef, it could have devastating effects on the ecosystem, which is already coping with global warming and recent flooding in the area. The majority of the sludge is being removed from ocean floors in Hay Point Port — a region that leads the world in coal exports. Although environmentalists are concerned about dumping one million tons of sludge on the Great Barrier Reef, officials with the North Queensland Bulk Ports Corporation do not believe it is an issue. The company just released a statement online about how the sludge dump will have a low impact on the coral reef and will only affect it in the short-term. The closer the sludge is dumped on the coral reef, the worse it will affect it in the long-term. Experts believe that if the sludge is placed farther out, then it will have less of an impact on the coral reef. That said, the waste still contains trace metals, which can harm the delicate ecosystem. The sludge controversy comes a year after Australia promised to dedicate $500 million AUD to preserve the Great Barrier Reef. Over the past few years, the coral reef has been reduced by 30 percent, mostly due to an invasive species of starfish called the crown-of-thorns and significant coral bleaching.

8 sustainable innovations in construction materials

Comments Off on 8 sustainable innovations in construction materials

The construction industry is responsible for a large percentage of carbon emissions . From sourcing to design to material manufacturing to building construction, the carbon dioxide output from projects around the world has a significant environmental impact. This has led to sustainable construction innovations that not only reduce the production of carbon dioxide, but also improve a building’s longevity, reduce  energy  bills and increase the use of natural light. Here is a list of some innovative construction materials and ideas that could revolutionize the industry and help us build a more sustainable future. Transparent wood Swedish researchers have turned wood into a material that is 85 percent transparent by compressing strips of wood veneer and replacing lignin with polymer. This product is light but just as strong as natural wood. It can be an eco-friendly alternative to glass and plastic. When used to build homes, transparent wood will reduce the need for artificial lighting, plus it is biodegradable. Related: Potato peels offer a sustainable alternative to traditional building materials Bamboo-reinforced concrete As a natural replacement of steel for reinforcing concrete, bamboo is gentler on the planet without compromising on durability. Bamboo-reinforced concrete also allows for better earthquake resistance. Because bamboo grows so quickly, it can easily be regenerated while simultaneously absorbing CO2. Cigarette butt bricks Smoking cigarettes is still a big part of cultures around the world, despite the negative effects on personal health . The butts also make up a significant percentage of waste. But researchers at RMIT University in Australia have discovered that adding cigarette butts to bricks reduces the amount of time and energy needed to bake them compared to traditional methods, plus the cigarette butt bricks are better insulators. Using cigarette butts in the brick-making process reduces waste and lessens the number of heavy metals that make their way into water and soil. Hydrogel The Institute for Advanced Architecture of Catalonia in Barcelona is leading the way in reducing the use of air conditioning by using hydrogel to create walls that can cool themselves. The architects are placing hydrogel bubbles in between ceramic panels that can be installed into existing walls. Inspired by the human body’s ability to cool itself, the hydrogel can absorb water when the air around it gets hot and starts to evaporate. This can reduce the temperature by 5 degrees Celsius, so you don’t have to keep the A/C cranking non-stop during the summer. Super-hydrophobic cement Recently, scientists have found a way to alter cement’s microstructure in a way that makes it absorb and reflect light. This finding has led to the creation of super-hydrophobic cement, or luminescent cement, which could replace traditional street lights and the energy they consume. Related: Green foods could clean up the construction industry Plus, this form of cement is more durable than conventional cement and could last up to 100 years compared to just 30 to 50 years. Synthetic spider silk With spider silk being one of the toughest natural materials on Earth, scientists all over the world have been trying to duplicate it. 3D printing has changed the game in the world of synthetic spider silk, and it could create a product made from water , silica and cellulose that is “stronger than steel and tougher than Kevlar” according to Smithsonian Magazine . This could change multiple industries like textiles, construction, automobiles and medical devices. Breathe Bricks A few years ago, architect Carmen Trudell started researching the air quality problems in Cairo, and that resulted in the creation of the Breathe Brick. Inspired by the treatment her brother received for kidney failure, Trudell started wondering if she could produce a building component that filters toxins. Trudell and her team “came up with the idea of putting a cyclone inside of the exterior wall” by developing the Breathe Brick . When using Breathe Bricks to build a wall, the faceted surface of the bricks pulls outside air into ports, then the cyclone filter spins the air and gets rid of particulate matter that causes pollution. LED and OLED lighting Lighting a commercial or residential building takes a lot of energy. So, over the past decade, LED (light emitting diode) and OLED (organic light emitting diode) have entered the marketplace to drastically reduce the amount of energy used to light up structures. Not only do LEDs use just 10 percent of the energy used by incandescent lighting and 50 percent of fluorescent lights, but they also last 40 times longer. The advantages of OLEDs are the slim size and the transparent material, allowing for natural lighting during the day before they light up at night. As technology continues to advance and materials change, the cost of LED and OLED should fall, making them both affordable and energy-efficient.

Kenyan activists are using human poop to make affordable cooking fuel

Comments Off on Kenyan activists are using human poop to make affordable cooking fuel

Resources are scarce in Kenya, and nearly half of the population lives below the poverty line , but they do have poop. Activists with Nakuru Water and Sanitation Services Company are providing clean fuel for local residents in the form of small balls of human feces. The group takes in truckloads of sewage from septic systems and pit latrines and transforms the waste into safe, economical briquettes that burn cleaner and longer than coal. And don’t worry: they are odor-free. Ordinarily, human feces can pose various health problems if left untreated or if disposed of improperly. Sometimes, it can even lead to cholera outbreaks or other sanitation -related diseases. However, because it is the most abundant and widely available human resource, Nakuru Water and Sanitation Services Company developed a method to turn it into an affordable, clean-burning fuel. To create the briquettes, the company slowly sun-dries the feces. Then, it treats it at a high temperature of 300 Celsius (572 Fahrenheit) in a kiln via a carbonizing process where sawdust is added to it. TreeHugger reports that the resulting product is then mixed with a small amount of molasses to act as a binder. It is then rolled into balls and dried. One kilo of the briquettes is said to cost just 50 cents USD — a very reasonable price for Kenyan citizens. John Irungu, the site manager at Nakuru Water and Sanitation Services Company, describes carbonization as “a process whereby we increase the carbon content of your materials.” He added, “In this case we are using the drum kiln whereby the sludge is fed, the drum has some holes at the bottom, these holes allow the oxygen to come in, in a controlled manner, that oxygen will only support combustion but to a certain level so that it doesn’t burn completely into ash. In this way, you are able to eliminate all the volatile matters, all the harmful gasses, and it is at this point that you ensure that your sludge doesn’t smell it is safe for handling when you are carrying out the other processes which is milling and briquette production.” Related: First-ever dog poop composting program in NYC comes to Brooklyn park It took some time to overcome the stigma that surrounds the use of human feces, but the company succeeded by informing residents that they could obtain a cleaner-burning cooking fuel for a fraction of the cost.

Posted by Al Jazeera English on Saturday, July 15, 2017 Every month, Nakuru Water and Sanitation Services Company produces about two tons of the human waste briquettes. By the end of the year, the goal is to produce 10 tons per month. This will occur once additional de-watering and carbonization equipment is procured, as it will scale up and optimize the present production methods. The company is also invested in the construction of more than 6,000 toilets that can collect waste. Someday, the company will expand its offerings elsewhere in Kenya, Africa. + Nakuru Water and Sanitation Services Company Via TreeHugger Images via  Nakuru Water and Sanitation Services Company

Comments Off on RIP Tobias Wong

We are shocked and saddened to read the news over on Core77 that NY’s iconoclast product designer Tobias Wong passed away over the weekend at the age of 35. We were big fans of Tobi’s wit and willingness to break molds, and it is clear that Wong will be dearly missed. Tobias had been the charming enfant-terrible / provocateur of the NY design scene for years, never shying away from pushing buttons and challenging design conventions.
