Methane Leaks Are Worse Than We Thought | Earth Wise

By Leave a Comment

Methane leaking from oil and gas wells is a real problem for the environment because methane is far more potent at trapping heat than carbon dioxide.   The EPA has estimated that about 1.4% of the methane produced by wells nationally leaks into the atmosphere.   However, environmental experts and energy industry engineers have been concerned that leaks from mines, wells, refineries, storage facilities, and pipelines are vastly underreported.  But until recently, there really wasn’t a good way to find out.

Researchers at Stanford University have developed a technique based on the use of hyperspectral cameras mounted to airplanes.  The cameras measure sunlight reflected off of chemicals in the air that are invisible to the human eye.  Each chemical, including methane, has a unique fingerprint.  Using these sensors, methane is easy to spot and the technique can measure the output of individual wells.

The researchers performed a study of almost every oil and gas asset in the New Mexico Permian Basin, one of the largest and highest-producing oil and gas regions in the world.  They surveyed the sites for an entire year.  They estimate that more than 9% of all methane produced in the region is being leaked into the skies, far more than EPA estimates.

The positive outcome of the survey is that the researchers found that fewer than 4% of the 26,000 sites studied produced half of all the methane emissions observed.  Being able to identify the so-called super-emitter sites and dealing with them could lead to a major improvement in the situation.

The new technique is more accurate, faster, and more cost-effective than current ways to monitor emissions.

New York Bight Offshore Wind | Earth Wise

By Leave a Comment

Late in February, the U.S. completed the most successful offshore wind lease auction in history.  The auction for rights to develop offshore wind in the New York Bight brought in a record $4.37 billion from the companies bidding for them.

The New York Bight is an area of ocean off the coasts of New York and New Jersey that the Bureau of Ocean Energy Management has divided into six lease areas for offshore wind development.  It covers a total of 480,000 acres.  The more than $4 billion secured in the auction is more than three times the revenue received from all U.S. offshore oil and gas lease auctions over the past five years.

Five out of the six winning bids have European connections in the form of various partnerships.  Europe has a far more advanced offshore wind market than the U.S. with a total of 25 GW of installations as of 2020.  Winning bidders included participation by RWE from Germany, British-owned National Grid, and Copenhagen Infrastructure Partners, among others.  Chicago-based Invenergy was the only American company without a European partner to have a winning bid.

The expected installed capacity for the 6 leased areas in the New York Bight is expected to be between 5.6 and 7 GW, enough to power 2 million homes.  The Bureau of Ocean Energy Management said capacity could be even higher.

The successful action has set the tone and expectations for auctions to come.  BOEM has six more offshore wind auctions planned over the next three years.  Forthcoming auctions are for areas of the Carolinas, Northern and Central California, the Gulf of Mexico, the Central Atlantic, Oregon, and the Gulf of Maine.

Turning Pollution Into Cash | Earth Wise     

By Leave a Comment

Power plants and other industrial facilities are a major source of carbon emissions.  There are a variety of techniques under development to prevent those emissions by capturing them rather than releasing them into the atmosphere.  All of them add costs to the functioning of the facility.  A good way to offset those costs is to convert the emissions into useful products, ideally making it profitable to capture emissions.

Engineers at the University of Cincinnati have developed an electrochemical system that converts carbon dioxide into ethylene, which is a chemical used in a wide range of manufacturing.  Ethylene has sometimes been called “the world’s most important chemical”.  It is used in many kinds of plastics, textiles, and the rubber found in tires and insulation. It is also used in heavy industry such as steel and cement plants as well as in the oil and gas industry.

The Cincinnati process is a two-stage cascade reaction that converts carbon dioxide to carbon monoxide and then into ethylene.  It is based on the underlying principle of the plug-flow reactor that is used for variety of production applications.  The study, published in the journal Nature Catalysis, demonstrates that the process has high ethylene selectivity – meaning that it effectively isolates the desired compound – as well as high productivity – meaning that it makes a lot of it.  The system will take more time to become truly economical, but the researchers are continuing to make progress on that front with improved catalysts.

The researchers believe that this technique can reduce carbon emissions and make a profit doing it.  Power plants and other facilities emit a lot of carbon dioxide.  With this process, it may be possible to capture it and produce a valuable chemical.

Corn Ethanol And The Climate | Earth Wise

By 1 Comment

The Renewable Fuel Standard legislation, first passed in 2005 and updated in 2007, requires billions of gallons of renewable fuel to be added to the country’s transportation fuel supplies.  It created the world’s largest biofuels program.

The standard was hailed as a major victory for the climate as well as a way to reduce our dependence upon foreign oil.

The intent of the legislation was to encourage various forms of renewable fuels – especially cellulosic ethanol from plant and wood fiber – to become an increasing part of the fuel mix.  That has yet to happen.  Instead, corn ethanol has been the backbone of the program.

Back in 2007, the EPA determined that ethanol from corn would lead to a 20% reduction in greenhouse gases compared to gasoline.  But the next year, a study published in the journal Nature projected that corn ethanol would double greenhouse gas emissions over 30 years because demand for corn would drive farmers to plow up increasing amounts of carbon-rich forest and grassland.

A new study published by researchers at the University of Wisconsin, Madison, has again concluded that corn-based ethanol may actually be worse for the climate than fossil-based gasoline as well as having other environmental downsides.  According to the study, since the fuel standard was passed, farmers have expanded corn production on nearly 7 million acres each year, causing the conversion of lands to cropland.  The result is that the carbon intensity of corn ethanol could be as much as 24% higher than gasoline.

The issue is still being debated in Congress, but if these results are verified, the time has come to revamp the terms of the renewable fuel standard.

Cleaning Up Abandoned Wells | Earth Wise      

By Leave a Comment

There are 130,000 documented abandoned oil and gas wells in the US, according to the Department of the Interior.  The key word is documented.  According to an EPA study in 2018, the actual number of abandoned wells could be as high as two or three million.  According to an analysis by the Environmental Defense Fund and McGill University, about nine million people in the United States live within a mile of one of these wells.

Some of these wells might be fairly harmless, and others might be quite dangerous.  Wells can emit a variety of gasses, including methane, which is a far stronger greenhouse gas than carbon dioxide.  Leaking wells are a major source of air and groundwater pollution.  Apart from methane, substances such as arsenic can continue to leak from wells even after they are no longer operational.

At the end of January, the Biden Administration announced a series of new actions to tackle methane pollution.  Among these measures is $1.15 billion in funds from the Department of the Interior that states can use to seal up abandoned oil and gas wells.  That funding comes from the Bipartisan Infrastructure Law passed in November, which sets aside $4.7 billion for a federal program dedicated to orphaned wells.

Addressing the largely ignored problem of abandoned wells is important from the standpoint of climate pollution as well as human health.  Efforts to plug the wells will also provide high-paying jobs

Other methane-reduction measures include increased enforcement from the Department of Transportation on reducing pipelines leaks, research funding for limiting methane emissions from beef and dairy farming, and technical assistance from the Department of Energy on well-plugging efforts.

Safely Storing Carbon | Earth Wise

By Leave a Comment

As carbon dioxide levels continue to increase in the atmosphere and emissions reductions aren’t happening as fast as needed, there is growing interest in carbon capture and storage technologies.

The idea is to capture the CO2 emitted from industrial processes or from the burning of fossil fuels in power generation, and then permanently store it out of harm’s way.  There are several different types of sites where the CO2 might be stored.  Deep saline aquifers are particularly desirable for the purpose, but depleted hydrocarbon reservoirs are commonplace and relatively simple to use.  These are oil and gas wells that have been drained of their resources.

In many cases, CO2 has already been injected into these depleted wells as a means of enhanced oil recovery.  Therefore, such wells provide a unique opportunity to study what happens to carbon dioxide when it’s stored in these places.

Researchers from Oxford University recently published a paper in the journal Nature that compared the state of depleted wells with injected carbon dioxide to that of wells without the injected gas.  They found that nearly 3/4 of the CO2 was dissolved in the groundwater.  Unexpectedly, they also found that 13-19% of the carbon dioxide was converted into methane by methanogenic bacteria.  Methane is less soluble, less compressible, and less reactive than carbon dioxide.

Producing methane in these wells is therefore undesirable.  Deeper sites that have temperatures too high for the bacteria to thrive are much more suitable.  This research is important for identifying future carbon capture and storage sites and for designing long-term monitoring programs that are essential for low-risk, long-term carbon storage.

Oil Drilling In Los Angeles | Earth Wise      

By Leave a Comment

Movies were not the first industry to boom in Los Angeles.  Oil was.  There was a lot of it, and it flowed close to the surface triggering rampant drilling all over the area.  By the 1920s, Los Angeles was one of the largest oil-exporting regions in the world.

A century later, there are over 20,000 active, idle, or abandoned wells spread across LA county, home to 10 million people.  Some are hidden behind facades; others are plainly visible, pumping away day and night.  About a third of Angelenos live less than a mile from an active well site.  In the last 20 years, improved oil extraction technology has actually led to a resurgence of oil drilling in Los Angeles.

Studies of the health impact of LA’s oil wells found that asthma is significantly more common among people living near oil wells than elsewhere in the county.  Surveys of residents’ lung functions revealed lower function on average when people live near wells.   Measurements of toxins in the air – such as benzene, toluene, and n-hexane – showed that levels of these substances were significantly reduced when oil production at a site stopped.

This issue has finally come to the forefront after a nearly a decade of community organizing and studies of adverse health effects.  In a unanimous vote on January 26, the Los Angeles City Council took the first step toward phasing out all oil and gas extraction in the city by declaring oil extraction a nonconforming land use.  The LA County Board of Supervisors voted unanimously to phase out oil extraction in unincorporated county areas.  Los Angeles’ long, troubled history with urban oil drilling appears to be nearing an end.

Synthetic Palm Oil | Earth Wise

By Leave a Comment

Palm oil is the world’s cheapest and most widely used vegetable oil.  Producing it is a primary driver of deforestation and biodiversity loss in the tropics.  In Borneo, for example, oil palm cultivation has accounted for more than half of all deforestation over the past two decades.   More than one million square miles of biodiversity hotspots could be threatened by oil palm cultivation, which could potentially affect more than 40% of all threatened bird, mammal, and amphibian species.

Today, the world consumes over 70 million tons of palm oil each year, used in products ranging from toothpaste and oat milk to biodiesel and laundry detergent.

Given this situation, there are now multiple companies developing microbial oils that might offer an alternative to palm oil while avoiding its most destructive impacts.

A company called C16 Biosciences is working on the problem in Manhattan, backed by $20 million from a Bill Gates’ climate solutions investment fund.  A California-based startup called Kiverdi is working to manufacture yeast oil using carbon captured from the atmosphere. 

Xylome, a Wisconsin-based startup is working to produce a palm oil alternative that they call “Yoil”, produced by a proprietary strain of yeast.  The oil from the yeast strain is remarkably similar to palm oil. 

The challenge is to be able to produce microbial oils at large scale and at a competitive price.  Unless valuable co-products could be manufactured along with the oil, it may be difficult to compete with palm oil.  Without regulatory pressures and willingness of consumers to pay more, it may be difficult to replace palm oil in many of its applications.

The Importance Of City Trees | Earth Wise

By Leave a Comment

It is well known that green spaces can improve the quality of life and create a better climate in cities.  City trees and vegetation can help reduce urban heat island effects by shading buildings and roads, deflecting radiation from the sun, and releasing moisture into the atmosphere.  City trees and green spaces have also been proven to increase property values, promote wildlife and plant diversity, reduce noise pollution, and improve human health.  But how important are trees and vegetation for producing cleaner air in cities?

According to a new study led by researchers at the University of Gothenburg in Sweden, trees do contribute to cleaner air in cities, but the degree to which they do so varies greatly between different locations. 

The research team measured air pollutants across seven urban settings in the city of Gothenburg, and compared them with pollutants on the leaves of deciduous trees.  The researchers chose to focus on polycyclic aromatic hydrocarbons (PAHs), which are pollutants generated primarily during the incomplete combustion of organic materials, like coal, oil, and wood.

The results revealed that the pollutants in leaves did increase over time.  The researchers were able to show a clear correlation between the level of air pollutants and the concentration of pollutants in leaves. 

But at the same time, the researchers discovered that pollution levels varied greatly between measurement sites.  For example, the levels of PAHs were seven times higher at the most polluted site (the city’s main bus station) than they were at a location on the periphery of the city.

The research team hopes its findings will be used to help guide the planning of future urban landscapes.

Carbon Capture In Denmark | Earth Wise

By Leave a Comment

Denmark has pledged to reduce greenhouse gas emissions 70% by 2030 compared with 1990 levels. The country has also banned oil exploration in Danish waters and plans to phase out offshore drilling in the North Sea by 2050.

Instead of pumping oil from the North Sea, Denmark plans to capture CO2 and store it there.  To meet its climate goals, Denmark is investing $2.4 billion in a plan to capture carbon dioxide from its energy and industrial sectors and inject it into the seabed in geological formations that previously held oil and gas deposits.

The first North Sea carbon capture and storage facilities will be put into service in 2025 and will remove nearly half a million tons of emissions from the atmosphere each year.  The carbon dioxide will be captured from energy and industrial sectors such as waste incineration and cement production.

There are multiple carbon capture projects underway around the world.  Many are directed at so-called direct air capture, which is taking carbon dioxide out of the air once it is already there.  In Iceland, a project named “Orca” is extracting CO2 from the air and piping into a processing facility where it is mixed with water and diverted into a deep underground well.  Other large direct air capture plants are being built in the U.S. Southwest and in Scotland.

Whether capturing carbon from industrial operations or directly from the air ultimately makes environmental and economic sense remains to be seen.  What is driving the development of these technologies is the troubling math that reducing emissions is not happening fast enough to stave off the destructive effects of climate change that will result from global temperatures rising too much.

Capturing Methane To Feed Fish | Earth Wise

By Leave a Comment

Methane in the atmosphere is an extremely potent greenhouse gas.  Its warming potential is about 85 times that of carbon dioxide over a 20-year period.  It also worsens air quality by increasing atmospheric ozone.  Many human activities add methane to the atmosphere, notably emissions from landfills and oil and gas facilities.

Capturing methane from these sources for subsequent use is currently uneconomical but new research from Stanford University analyzes the market for using the methane to feed bacteria to produce fishmeal.

Methane-consuming bacteria called methanotrophs can be grown in chilled, water-filled bioreactors containing pressurized methane, oxygen, and nutrients.  The bacteria produce a protein-rich biomass that can be used as fishmeal in aquaculture.  This could offset demand for fishmeal made from small fish or plant-based feeds that require land, water, and fertilizer.

Some companies already do this using natural gas provided by utility pipelines, but it would be far better for the environment to use methane emitted at large landfills, wastewater treatment plants, and oil and gas facilities.

Consumption of seafood has more than quadrupled since 1960, depleting wild fish stocks.  Farmed fish now provide half of all the animal-sourced seafood we eat.

The Stanford research analyzed the cost of methanotrophic fishmeal production under various scenarios and found it to be very competitive with and in some cases considerably cheaper than current market prices for fishmeal. 

According to the study, this process could profitably supply total global demand for fishmeal with methane captured in the U.S. alone.

Is Peak Oil Here? | Earth Wise

By Leave a Comment

For many years there has been talk of “peak oil”, the point at which rising world oil consumption would peak and then start declining.  Some analysts have been predicting that this could happen by the 2030s.   But the coronavirus pandemic drove a 9% slump in oil demand in 2020 that some economists are saying might never be entirely reversed.

There are three major forces driving down the world’s appetite for oil:  decarbonization of economies to meet the goals of the Paris climate agreement, declining demand for oil as renewable energy sources and electric vehicles are increasingly adopted, and detoxification as cities act to curb particulates and emissions from burning petroleum.

The largest single factor is electric vehicles.  Automobiles currently consume almost half of the world’s oil.  As of the end of 2020, there were an estimated 10 million electric cars as well as more than 600,000 electric buses and trucks.  This is still less than 1% of all vehicles, but 5% of all new cars being bought are now electric and the number is growing rapidly.  Experts estimate that nearly a quarter of global car sales will be electric vehicles by 2025 and many car manufacturers are promising to sell only electric cars within the next 10 years.

The decline in oil demand is pretty much inevitable at this point.  The main question is how quickly it will happen.  Road transport makes up 48% of global oil demand, petrochemicals account for 14%, aviation 7%, and shipping 6%.  Ultimately all these things are likely to diminish over time. 

Only time will tell, but the long-awaited arrival of peak oil may already have happened.

Have We Reached Peak Internal Combustion Engine? | Earth Wise

By 1 Comment

According to new analysis from Bloomberg New Energy Finance, global sales of gas-powered cars may well have peaked in 2017, representing a significant milestone in the transition to electric vehicles.

Demand for gas cars dropped in 2018 and 2019, and then plummeted in 2020 as a result of the coronavirus pandemic.  While sales are surely picking up as the pandemic ebbs, the increasing demand (and supply as well) for plug-in vehicles is likely to put gas-powered cars in a state of permanent decline.

Global EV sales are projected to go from 3.1 million last year to 14 million in 2025.  The growth is being driven by falling battery prices, government policies, and increasing choices of vehicles.  Virtually all automobile manufacturers are introducing electric vehicles over the next couple of years and increasing numbers of them are planning a complete transition to EVs in the near future.  Projections are that EVs will account for the majority of new car sales by 2035.

While all this progress is encouraging, there are still over a billion gas- and diesel-powered cars on the road and the fleet turns over slowly.  The current average operating life of cars here in the US is 12 years.

To reach the net-zero carbon emission goals by 2050 as many governments have mandated, additional policies and regulations will be needed.  For example, electric cars will need to account for essentially all new sales by 2035, not just the majority.  Reaching net-zero by mid-century will require all hands on deck, including trucks and heavy commercial vehicles that have barely started to become electrified.

Post-COVID Emissions Rebound | Earth Wise

By Leave a Comment

The extensive shutdowns associated with the COVID-19 pandemic resulted in reduced activity across many sectors of the global economy.  As a result, global pollution and greenhouse gas emissions also saw lower levels.  As the COVID crisis lessens, an economic recovery is growing and as that occurs, emissions are on the rise.

The International Energy Agency forecasts that energy-related carbon dioxide emissions are projected to increase by 1.5 billion tons this year, the second-largest increase in history.

The emissions increase in 2021 is expected to be nearly 5%, reversing most of last year’s emissions decline caused by the pandemic. This would be the largest annual rise since the 2010 recovery from the global financial crisis.  In many places across the globe, people are making up for lost time and doing more of all the things that cause carbon emissions.

A key driver of the emissions increase is a rise in coal use.  The forecast is that coal-burning in 2021 would come close to the all-time peak of 2014.  Both natural gas and oil use are also expected to increase this year.  These increases are in spite of a predicted 17% increase in electricity generation from wind power and an 18% increase in solar-power generation. 

Atmospheric concentrations of CO2 are now at 417 parts per million and have increased by 3 PPM in the past year.  If human CO2 emissions are not reined in, atmospheric concentrations of planet-warming greenhouse gases could double those of pre-Industrial levels by mid-century, which would have disastrous impacts on the climate.

Not Such Climate Champions | Earth Wise

By Leave a Comment

The goal of the Paris Climate Accord is to limit warming to below 2 degrees Celsius and if possible to stay as close as close to 1.5 degrees above pre-industrial levels.  Nations around the world have made commitments to drastically reduce their carbon dioxide emissions from the use of fossil fuels that are in large part responsible for the rising temperatures.

There are a number of countries that proudly claim to be leading the world in the fight against climate change but who are actually still a major part of the problem.  Among these are Norway, the UK, and Canada.

Norway powers its streetlamps with renewables, runs its public transportation system entirely by renewable energy, and leads the world in the adoption of electric cars.  Both the UK and Canada have set ambitious targets for emissions reductions leading to zero net emissions by 2050. 

The problem is that under the Paris Agreement, each country is only responsible for the greenhouse gas emissions produced within its territory.  That means that the UK, Canada, and Norway (like many other countries) don’t need to worry about the emissions caused by the burning of their oil, gas, and coal in other places around the world.

Norway’s annual domestic emissions reached about 53 million tons in 2017 according to its government.  The emissions from the oil and gas Norway sold abroad reached roughly 470 million tons in 2017.  Canada has huge proven oil reserves it is exploiting.

Canada, Norway, and the UK all plan to keep producing fossil fuels, investing in new fossil fuel projects, and explorations.  As long as this continues, these countries are not really climate champions; they are climate hypocrites.

What’s The Best Way To Reduce Emissions? | Earth Wise

By Leave a Comment

A carbon tax is a fee imposed on the burning of carbon-based fuels, like coal, oil, and gas.  It’s one way to make the users of carbon fuels pay for the climate damage caused by releasing carbon dioxide into the atmosphere. 

According to a new study by researchers at Ohio State University, putting a price on producing carbon is the cheapest and most efficient policy change that legislators can make in order to reduce climate change-causing emissions. 

The case study, which was recently published in the journal Current Sustainable/Renewable Energy Reports, looked at the impact that a variety of policy changes would have on reducing carbon dioxide emissions from electricity generation in Texas. The researchers found that assigning a price to carbon, based on the cost of climate change, was most effective. 

The study did not look at how policy changes might affect the reliability of the Texas power system, an important consideration after the failure of the state’s power grid following winter storms in February. 

But the study did examine other policies and found that they were either more expensive or not as effective, including mandates that a certain amount of energy in a portfolio come from renewable sources.  Subsidizing renewable energy sources was also found to be less effective. 

According to researchers, market-based solutions have previously proven effective combating environmental issues.  For example, a cap-and-trade approach was used to reduce levels of sulfur dioxide, one of the chemicals that causes acid rain. 

For the sake of the climate, we should probably tax carbon.

Drilling Rights In The Arctic National Wildlife Refuge | Earth Wise

By Leave a Comment

The battle to prevent oil and gas drilling rights from being sold in the Arctic National Wildlife Refuge in Alaska has been going on for 40 years.  The Trump administration spent nearly four years pushing to auction off those drilling rights and finally accomplished it in early January.

The ANWR was created in 1960 and is the largest intact wilderness in the U.S., covering nearly 30,000 square miles in Alaska.  It is an important breeding habitat for polar bears as well as the home of more than 200 other species including caribou, arctic foxes, golden eagles, and snowy owls.  Parts of it are also sacred ground for the indigenous Gwich’in people.

The auction carved out a 5% slice of the refuge for leases and proponents anticipated it would generate billions of dollars in revenues that would offset tax cuts in Alaska.

Of the 22 parcels of land offered, totaling 1.1 million acres, only 12 were bid on at all and the state of Alaska was the sole bidder on 9 of those.  In total, the auction raised a paltry $14 million. 

Whether the remarkable absence of interest was due to a lack of infrastructure or roads around the region, the decline of fossil fuel investments and use during the pandemic, or the anticipation that any leases would be the subject of endless legal battles by indigenous tribes and environmental activists, the net result was that the auction was basically a flop.

President Biden has stated that he is entirely against Arctic drilling, so the new administration is likely to try to repeal or interfere with any drilling leases or other industrial activity in the ANWR.

Shifting Climate Attitudes – Even In Texas | Earth Wise

By Leave a Comment

Any conversation about climate policy and energy in the United States has to take Texas into consideration.  Texas leads the nation in energy production, providing more than one-fifth of U.S. domestically produced energy.  Texas also uses more energy than any other state and accounts for almost one-seventh of total U.S. energy consumption.  The state’s industrial sector, which includes petroleum refining and chemical manufacturing, accounts for almost half of Texas energy consumption.

As a result, longstanding skepticism among Texans toward the climate movement has represented a real impediment in developing and implementing effective climate policy in this country.  But according to new research at the University of Houston, attitudes in Texas have changed and now mirror those in the rest of the United States.

About 80% of Americans believe that climate change is happening, and now about 81% of Texans hold the same view.  Two out of three Americans are worried about climate change; more than 60% of Texans agree.

Nationwide, 55% agree that the oil and gas industries have deliberately misled people on climate change; 49% of Texans agree. 64% of Americans say hydraulic fracking has a negative effect on the environment and 61% of Texans agree.  People everywhere are willing to pay more for carbon-neutral energy, and a higher premium for gasoline as well.

Mitigation strategies for climate change are not well understood.  While 61% nationwide have heard of carbon taxes, less than half are familiar with carbon management, and only a third have heard of carbon pricing.

As the U.S. heads toward reengaging in efforts to address climate change, Texans appear to have caught up with the rest of the nation.

Replacing Plastic Tableware | Earth Wise

By Leave a Comment

Plastics have been described as the “ubiquitous workhorse material of the modern economy.”  But their versatility, pliability, and durability comes at a heavy price to the environment.  Plastic pollution is quite literally everywhere.  Plastic debris and microplastic particles can be found in every corner of the globe, including the Arctic and Antarctic. 

The scourge of plastic pollution is driving scientists to create ecologically-friendly alternatives.  According to a paper recently published in the journal Matter, scientists have developed “green” tableware made from sugarcane and bamboo that doesn’t sacrifice on convenience or functionality.  This eco-friendly tableware could serve as a permanent replacement for plastic cups and other disposable plastic containers. 

Traditional plastic polymers, a product of petroleum, can take as long as 1,000 years to decompose in landfills.  The new material only takes 60 days to break down.

To create this material, scientists used bamboo and bagasse, also known as sugarcane pulp.  Bagasse is one of the largest food-industry waste products.  The researchers wound the fibers together to form a mechanically stable and biodegradable material.  They added an alkyl ketene dimer, an eco-friendly chemical, to increase the oil and water resistance of the material.  The green material is durable enough to hold liquids like hot coffee and hot greasy foods like pizza.   

There’s another advantage: the green material’s manufacturing process emits 97% less CO2 than the process to make commercial plastic containers.  The next step is to lower the manufacturing cost.  While the cost of cups made from the green material is $2,333 per ton, traditional cups made from plastic are still slightly cheaper at $2,177 per ton.

Last February, Amazon CEO Jeff Bezos announced that he was launching the Bezos Earth Fund that would grant money to scientists, activists, NGOs and others making an effort to help preserve and protect the natural world.  The fund would start out with $10 billion and would begin issuing grants later in the year.

In November, the first Earth Fund award recipients were announced.  In total, 16 organizations will be receiving nearly $800 million in funding.

The largest awards include the following:  the Environmental Defense Fund received $100 million to build and launch MethaneSAT, a satellite that will locate and measure sources of methane pollution around the world and provide public access to data that assures accountability.

The Natural Resources Defense Council was awarded $100 million to advance climate solutions and legislation at the state level, promote policies and programs focused on reducing oil and gas production, protect and restore ecosystems that store carbon, and accelerate sustainable and regenerative agriculture practices.

The Nature Conservancy also received $100 million and plans to use the money to help protect the Emerald Edge forest.  (That is the largest intact coastal rainforest on Earth, spanning 100 million acres through Washington, British Columbia and Alaska).

The World Resources Institute will receive $100 million, doled out over five years, to be used to develop a satellite-based monitoring system to advance natural climate solutions around the world.

An additional $100 million award went to the World Wildlife Fund to help protect and restore mangroves, develop new markets for seaweed as an alternative to fossil fuel-based products, and to protect forests and other ecosystems around the world.
