HOW TO: Turn your food waste into clean energy

February 21, 2018 by  
Filed under Eco, Green

Each year, 1.3 billion tons of food ends up lost or wasted — 46 percent of the world’s garbage. While the global food waste situation is what you’d call a “doozy,” consumers and companies like HomeBiogas are determined to turn food waste into clean, usable energy. Read on to find out how. What Is HomeBiogas? HomeBiogas is one of several successful projects to come about from Kickstarter. The Israeli company, which began its crowdfunding efforts in 2015, focuses on turning everyday food waste into energy for your home. How do they do it? With compact, household-sized biogas digesters that support anaerobic digestion, a process with zero oxygen and hungry bacteria that are ready to dive into last week’s moldy bread. Since the company’s launch in 2015, consumers have responded enthusiastically to their efforts. In fact, they blew past their crowdfunding goal for both biogas products. The second version, HomeBiogas 2.0 , exceeded its initial goal by more than 400 percent. In dollars and cents, that translates to more than $490,000. How Does HomeBiogas Work? OK, so consumers love it, but how does HomeBiogas work? Like the 27 million biogas plants in China, but on a smaller, less commercial scale. The process is alike, however, because every biogas system operates on the same premise — anaerobic digestion. Here’s a breakdown — pun intended — of the HomeBiogas process: 1. A user pours food waste into a funnel, where it enters the oxygen-free tank. 2. Water and bacteria begin digestion. Bacteria can come from a starter kit or from nitrogen-rich substances like chicken manure and shellfish shells. 3. Fermentation produces methane, carbon dioxide, and other gases. 4. Gas enters a storage tank for use via a pipe to your kitchen. 5. Liquid fertilizer becomes accessible via a spout for use in landscaping. In addition to bacteria, sunlight also contributes to biogas. Why? Bacteria love and thrive in heat, which means a well-placed HomeBiogas in a climate with temperatures around 68 degrees Fahrenheit digests food waste at a more efficient rate, which translates to more clean energy for you. What Does HomeBiogas 2.0 Do Better? With the basics of anaerobic digestion established, as well as the processes behind the original HomeBiogas, it’s time to explore how HomeBiogas 2.0 offers an edge over its predecessor: Upgraded efficiency: The new model promises a 50 percent boost to its processes. Increased capacity: HomeBiogas 2.0 doubles its storage with space to hold up to 185 gallons. Improved construction: The latest biogas digestor offers a lighter weight, plus more durable build. Enhanced installation: HomeBiogas 2.0 requires only an hour of your time to install. And if you’re worried about HomeBiogas filling your home with the nose-assaulting smell of decomposing food, forget about it. The team equipped its products with an airtight seal and filter, while using water to submerge food waste in the tank eliminates odor. How Can You Use This Clean Energy? Back in the 2000s, The Black Eyed Peas asked, “What you gon’ do with all that junk?” While they weren’t referencing food waste, there are plenty of ways to use the clean energy from your converted organic junk. Applications for the clean energy and liquid fertilizer produced by a HomeBiogas include: Powering your stove or grill: Cook up to three hours each day. Just place your HomeBiogas less than 65 feet from your kitchen or patio and connect the two with an included pipe. The biogas can connect to a countertop stove or double-burner setup. Fertilizing your gardens: Nurture your gardens with the liquid fertilizer produced by anaerobic digestion. HomeBiogas 2.0 features a user-friendly pouring sleeve, which makes it easy to dispense fertilizer into a water pail. Helping your neighbor: Support families in underserved communities. When you purchase a HomeBiogas 2.0, the company directs some of those funds to install their products in countries like Jordan and Uganda to combat indoor air pollution from cooking fuels. Like solar, wind and geothermal, biogas is a renewable energy source — and one that’s financially viable for consumers. As long as you have access to organic materials, like plants, you can count on the energy from biogas. As an additional benefit, biogas powers itself with pre-existing waste. What Does HomeBiogas Mean for the Future? Our planet wastes an enormous amount of food, yet the efforts of HomeBiogas and consumers around the globe demonstrate there is a motivation to do better and to reduce the waste that’s dominating the world’s landfills. What does that mean for the future? Hopefully that more people will adopt a lifestyle that thrives on clean, green energy. + HomeBiogas Images via HomeBiogas

BP’s chief economist predicts plastic bans will slash oil demand

February 21, 2018 by  
Filed under Eco, Green

Oil giant BP has predicted that increased regulation on plastic pollution around the world will result in decreased demand for petroleum, the key ingredient in most plastic. “We think we’re going to see increasing regulation against some types of petrochemical products, particularly single-use plastics,” BP’s Chief Economist Spencer Dale told Bloomberg . “As a result of that, we have less growth in non-combusted oils than we otherwise would have done.” While petrochemicals are predicted to continue as the largest driver of oil consumption, BP also predicts that oil demand will drop by two million barrels a day as a result of developing plastic regulations. BP also predicts that oil production will continue to rise over the next two decades, apparently peaking in the mid-2030s. Notably, this forecast expects an oil peak nearly a decade earlier than BP’s prediction last year. Despite its estimation that one third of total miles driven will be powered by electricity by 2040, BP does not expect the electric vehicle market to impact oil dramatically. “Selling more EVs will tend to have almost no effect on oil demand because now I can sell a greater number of large cars or I can do less investment in light weighting,” said Dale. This assumes that large, heavy, fossil-fuel-powered cars continue to be profitable. Related: Beer with biodegradable six-pack rings finally hits the market BP also revised its expectations from previous years regarding the growth of renewable energy , with the company now estimating that renewable energy will constitute 40 percent of all energy growth in the near future. “We cannot predict where these changes will take us, but we can use this knowledge to get fit and ready to play our role in meeting the energy needs of tomorrow,” said BP Chief Executive Officer Bob Dudley in a statement. To prepare for a cleaner energy future, BP has purchased a $200 million stake in British solar developer Lightsource Renewable Energy Ltd. and is reportedly considering purchasing Terra Firma’s Rete Rinnovabile Srl, a solar company based in Italy.

California bill could ban all new fossil-fueled cars by 2040

Comments Off on California bill could ban all new fossil-fueled cars by 2040

California could ban all new fossil fuel cars from 2040 under a bill introduced this week by Assemblymember Phil Ting , a Democrat of San Francisco. If it passes, the Clean Cars 2040 act would require all new cars sold in the state to be zero emissions vehicles. Ting said in a statement , “We’re at an inflection point: we’ve got to address the harmful emissions that cause climate change .” AB 1745, or the Clean Cars 2040 Act, would require every passenger vehicle sold in California to be zero emissions after January 1, 2040. Ting said fossil fuel vehicles are responsible for almost 40 percent of greenhouse gas emissions in the state, so “achieving the goal of electrification of transportation is crucial for the health of our people and the planet.” NextGen America president Tom Steyer said polluting cars are California’s biggest source of carbon emissions . The bill would not apply to commercial vehicles greater than 10,000 pounds, just passenger cars. It also wouldn’t apply to cars owned by people in other states moving to California. Related: Scotland to phase out new gas and diesel cars by 2032 California hopes to reduce greenhouse gas emissions by 40 percent under 1990 levels by 2030. Governor Jerry Brown aims to have 1.5 million zero emission cars on the streets by 2025, and there are almost 300,000 EVs registered in CA already. But the state still has a ways to go: the San Francisco Chronicle said in 2016 that while 2.1 million new cars were sold, only 1.9 percent of those were zero emissions. The bill already has support from some environmental groups. Earthjustice staff attorney Adrian Martinez said in Ting’s statement, “Reducing fossil fuels emissions should be California’s highest priority. With this legislation, California will be taking combustion polluting vehicles off the road…helping us to finally address air pollution and better equipping us to combat climate change. I urge our state’s leaders to pass this important legislation.” Via Assemblymember Phil Ting , the San Francisco Chronicle , and Engadget Images via Depositphotos ( 1 , 2 , 3 )
