The methane impact of organic waste vs fossil fuel emissions

Comments Off on The methane impact of organic waste vs fossil fuel emissions

While the focus is usually on fossil fuel  emissions  as the main climate change culprit, a new analysis by the nonprofit  Energy Vision  concludes that reducing emissions from organic waste would more steeply reduce methane. And it would cost less to accomplish. Last week the EU and U.S. announced their commitment to cutting methane emissions by 30% by 2030, as compared with 2020 levels. Congress has allocated billions of dollars to target methane emitted by the oil and gas industry. The EPA is planning stricter regulations to ensure that oil and gas companies locate and repair methane leaks ASAP. Inhabitat: EPA loosens restrictions on methane emissions “Lowering methane emissions in the  fossil fuel  sector is critically important, but at the same time, policymakers should understand that there are much more efficient ways of cutting methane emissions than plugging methane leaks in abandoned oil and gas operations,” said Energy Vision president Matt Tomich, as reported by PR Newswire. “Our research shows that trapping the methane biogases from decomposing organic wastes could cut methane emissions more deeply and at much lower cost.” While capping abandoned oil and gas wells can prevent greenhouse gas emissions to the tune of $67 per ton of carbon dioxide equivalent, Energy Vision found a much cheaper way to reach the same outcome. If organic  wastes  are processed in anaerobic digesters, which turn them into ultra-low-carbon renewable natural gas (RNG), we can avoid that same ton of greenhouse gas emissions for only $16. The report said that investing $5.5 billion in 400 new RNG projects could eliminate 33 million tons of  carbon dioxide  equivalent per year. This could be accomplished at a fraction of the $50-$100 billion cost of capping abandoned oil and gas wells. Methane accounted for approximately 10% of greenhouse gas emissions from human activities within the USA in 2019. This includes raising livestock and methane leaks from natural gas facilities. While methane doesn’t stay in the atmosphere nearly as long as carbon dioxide, it traps more  radiation . According to the EPA, the comparative pound-for-pound impact of methane over a hundred-year period is 25 times greater for methane than for carbon dioxide.

This company wants to turn food waste into building materials heres how

Comments Off on This company wants to turn food waste into building materials heres how

What do peanuts, rice, bananas, potatoes, and mushrooms have in common? In addition to being delicious, they could be transformed into building materials. In a report entitled The Urban Bio-Loop , the Arup group proposes to use food waste (something developed nations have an abundance of) to develop low-cost and eco-friendly materials for use in construction. The authors of the report aim to demonstrate ‘that a different paradigm for materials in construction is possible.” Because first-world nations, such as the United States , waste up to 40 percent of all food , the goal is to turn the waste into a resource for the creation of “construction, engineering, and architecture products,” reports Archinect . This could be done by modifying the traditional waste management system. Discarded organic materials that could prove useful include peanut shells, which could be used to create low-cost partition boards that are resistant to fire and ice; rice , which could be turned into ash and mixed with cement to eliminate the need for fillers; bananas, a fruit whose leaves can make rugged textiles as a result of high-strength fibers; mushrooms, which can be used to grow buildings ; and potato peels, which can be cleaned, pressed and dried to produce a light, fire-resistant and water-repellent insulating material. The group argues that using food waste for building would contribute to a circular economy where organic waste is put to use, rather than tossed into landfills . Repurposing food waste would also reduce the amount of methane that is produced when fruit and vegetable scraps slowly decompose. The gas contributes to global warming , a phenomenon which results in warming temperatures, rising sea levels, and worsening natural disasters. Related: The free grocery store fighting food waste and hunger Arup’s goal is to ameliorate rising levels of waste and a shortage of raw material. Using the low-cost, low-carbon materials would go a long way towards this goal. + “ The Urban Bio-Loop” Via Archinect Images via Wikipedia , Arup Group

Here’s some climate hope: global CO2 emissions stayed static last year

Comments Off on Here’s some climate hope: global CO2 emissions stayed static last year

The fall of coal and rise of renewable energy could be reducing global carbon dioxide (CO2) emissions . The Netherlands Environmental Assessment Agency (NEAA) published data this week showing global CO2 emissions remained stationary in 2016. Economist Nicholas Stern said, “These results are a welcome indication that we are nearing the peak in global annual emissions of greenhouse gases .” Every one of the largest emitting nations, minus India, saw their carbon emissions stay the same or fall. While that’s great news, the same can’t be said of all countries: Indonesia, for example, saw carbon emissions rise, as did Malaysia, Turkey, the Philippines, and Ukraine. NEAA attributed the slowdown in increasing CO2 emissions to switching away from coal to natural gas and renewable energy. Related: The world’s CO2 emissions have not increased in the past three years While NEAA said global CO2 emission levels “were more or less stable in 2015 and 2016,” total global greenhouse gas emissions did increase by around 0.5 percent. NEAA said that rise was largely due to an increase in non-CO2 emission levels, from compounds like nitrous oxide, methane , and fluorinated gases. NEAA report chief researcher Jos Olivier said, “There is no guarantee that CO2 emissions will from now on be flat or descending.” There’s still a victory for some major emitters. China saw CO2 emissions fall by 0.3 percent last year. The United States’ CO2 emissions fell by two percent, Russia’s by 2.1 percent, and the United Kingdom’s by 6.4 percent. The European Union’s emissions stayed flat. We need to keep taking climate action ; Stern said in order to meet the goals of the 2015 Paris Agreement , nations must accelerate their emissions reductions. But he still seemed hopeful, saying, “These results from the Dutch government show that there is a real opportunity to get on track.” Via Netherlands Environmental Assessment Agency and The Guardian Images via Petter Rudwall on Unsplash and Antonio Garcia on Unsplash

Comments Off on C.F. Mller’s stunning Low Energy Center in London showcases an innovative use of steel

Europe’s largest new residential heat network – the Greenwich Peninsula Low Energy Center in London – saves over 20,000 tons of carbon every year. C.F. Møller Architects and British artist Conrad Shawcross  designed the groundbreaking facility, which is clad in hundreds of triangular panels that fold and flow across the surface of the tower. The center won this year’s coveted GAGA Architecture Award for the most innovative and effective use of galvanized steelwork. The Greenwich Peninsula Low Energy Center sits at the entrance of the peninsula next to the Blackwall Tunnel Approach. It houses boilers and CHP that provide heat energy to the businesses and homes due to be built in the coming years Its impressive appearance can be attributed to Conrad Shawcross. The artist designed the facade of the 160-foot (49 meter) high tower as a way of communicating commitment to sustainable and affordable energy for all. Related: C.F.

Named ‘The Optic Cloak’ the structure is formed of hundreds of triangular panels – each the size of a London bus – folded across the surface of the tower forming complex geometric patterns. + C.F.
