A billion pound problem

By 1 Comment

Nearly two billion pounds of pumpkins are grown each year in the U.S.  But we actually don’t eat the vast majority of them.  Instead, most pumpkins are carved or otherwise decorated, and placed on porches across the country during Halloween.  But now that the holiday has come and gone, what happens to all those sagging masterpieces?

Simply put, we usually just throw them out.  In the days after Halloween, as much as 1.3 billion pounds of pumpkin winds up in landfills.  When left there to decompose, the pumpkins produce methane, a potent greenhouse gas that affects climate change by contributing to increased warming. 

Here are some ways to keep pumpkins out of the landfills this year and make Halloween festivities more sustainable. 

If the pumpkin is still in good shape, use the outer, meaty part of the pumpkin to make a fresh version of pumpkin puree.  Pumpkin puree is a common ingredient in baked goods like muffins, breads, and pies, especially during this time of the year.  The pumpkin seeds can also be scooped out, rinsed, and salted or spiced, and then baked in the oven, resulting in a delicious snack.

Pumpkins also have the potential to turn into great soil through composting. Pumpkins are just over 90% water, which help naturally add moisture to compost piles that need to be damp to effectively decompose food waste.

If eating or composting the pumpkins isn’t an option, consider donating them to a local farm.  Farmers will often collect pumpkins as treats for their pigs, goats, and other animals. 

The scariest part of Halloween shouldn’t be the waste.

Life In The Garbage Patch | Earth Wise

By Leave a Comment

A team of scientists has found thriving communities of coastal creatures living thousands of miles from their original homes and now ensconced on plastic debris in the Great Pacific Garbage Patch. 

A new study published in the journal Nature Ecology & Evolution reports that dozens of species of coastal invertebrate organisms – including tiny crabs and anemones – have been able to survive and reproduce on plastic garbage that has been floating in the ocean for years.

The Great Pacific Garbage Patch is an area in the ocean between California and Hawaii, larger than Texas, where plastic debris has been collected by the North Pacific Subtropical Gyre, one of five huge, spinning circular currents in the world’s oceans.  The patch is estimated to contain about 1.8 trillion pieces of plastic weighing an estimated 90,000 tons.  The Ocean Cleanup Initiative is dedicated to removing this immense accumulation of plastic, but it is an immense job.

Researchers discovered this new ecosystem after analyzing plastic samples collected by The Ocean Cleanup organization during its expeditions in the Pacific.  They were surprised to find 37 different invertebrate species that normally live in coastal water and only a dozen species that live in open waters.  These species have made their way from North America and have thrived.  So, the garbage patch has created a novel community that didn’t previously exist.

Debris from the Great Pacific Garbage patch constitutes the majority of debris arriving on Hawaiian beaches and reefs.  Hawaii’s fragile marine ecosystems have long been protected from invasive species because of the very long distances from North America or Asia.  With the coastal species now inhabiting the garbage patch, there is increased danger of colonization by them in Hawaii’s ecosystems.

Keeping Trash Out Of The Ocean | Earth Wise

By Leave a Comment

The Ocean Cleanup is a non-profit organization, founded in 2013 by Dutch inventor Boyan Slat, to develop and scale technologies to rid the world’s oceans of plastic.  It is an organization that proudly declares that its primary aim is to put itself out of business by successfully cleaning up the oceans.

A major activity of The Ocean Cleanup is efforts to clean the ocean garbage patches that have accumulated in several places, best-known of which is the Great Pacific Garbage Patch.  The effort involves use of large U-shaped floating barriers that act as an artificial coastline to trap garbage which is then funneled into a barge for disposal.  Ten full-sized systems will be needed to clean up the Great Pacific Garbage Patch.

A second activity of The Ocean Cleanup is preventing garbage in rivers from making its way into the oceans.  Rivers are the main source of ocean plastic pollution.  The Ocean Cleanup has developed river machines called Interceptors that capture garbage for disposal.  Last fall, they installed a machine called Interceptor 007 in Ballona Creek, a waterway in the Los Angeles area.  In the first rainfall after installation, the Interceptor managed to stop 35,000 pounds of waste from entering the ocean in just a few days.

The original Interceptor models have been deployed in Indonesia, Malaysia, the Dominican Republic, and Vietnam. A different type called the Interceptor Trashfence is being tested in Guatemala.

The Ocean Cleanup states that if fleets of its barrier systems are installed in all the garbage patches and Interceptors in the 1000 most significant rivers, 90% of floating ocean plastic can be removed by 2040.

Phasing Out Disposables | Earth Wise      

By Leave a Comment

Humans generate a remarkable amount of garbage.  According to the World Bank, humans produce 4.5 trillion pounds of trash every year, with at least 33% of this garbage not managed in an environmentally-safe manner. By 2050, global garbage generation is expected to reach nearly 7.5 trillion pounds a year. 

Globally, an average of 1.6 lbs of waste is generated per person per day.  While high-income countries only account for 16% of the global population, they are responsible for about 34% of the world’s waste. 

But almost everything humans throw away was bought from a company.   Whether it was the packaging or the product itself, we purchased it from somewhere.  There’s a growing movement to hold the companies responsible for the trash they produce. 

Faced with increasing consumer consciousness, many companies are stepping up and announcing initiatives to reduce their waste.  Starbucks is one of them.  The company’s white logo-emblazoned paper cups and clear plastic cups are instantly recognizable symbols of the brand.  But these ubiquitous cups are disposable and also serve as a symbol of our throwaway society. 

By the end of next year, Starbucks is planning to allow customers to use their own personal mugs at every location in the U.S. and Canada.  By 2025, the company wants every customer to be able to use either their own mug or to borrow a ceramic or reusable to-go mug.  This borrow-a-mug program is currently being tested in eight different markets around the globe. 

In lieu of regulation mandating corporate responsibility for waste, we will have to hope that more companies do the right thing.

Cleaning Up the Garbage Patch

By Leave a Comment

We have been talking about the Great Pacific Garbage Patch for several years.  Two years ago, we reported on the activities of a company called Ocean Cleanup, founded five years ago by an 18-year-old Dutch entrepreneur named Boyan Slat.  Two years ago, the company was conducting comprehensive surveys of the patch, which covers an area twice the size of Texas and contains some 80,000 tons of plastic debris.

A Ton Of Plastic Per Person

By Leave a Comment

A study by the American Association for the Advancement of Science has produced an estimate of the total amount of plastic manufactured worldwide since the 1950s.  The researchers then measured that data against statistics on recycling, incineration and discard rates.  The results are sobering.

We have talked about the problem of food waste before.  About 40% of the food produced in the United States goes to waste, which is a truly shameful statistic.  According to a Business for Social Responsibility study on the subject, about 44% of the food that goes into landfills comes from homes.  About a third comes from the food service industry.

Bidding ‘Adieu’ To Plastics

By

The use of plastics has increased 20-fold in the past 50 years, and production of plastics is expected to double again in the next 20 years.  According to Eco Watch, the average American throws away approximately 185 pounds of plastic every year.  And nearly one-third of all discarded plastic is not properly disposed of or recycled.

Too Much Waste

By

As the world’s population grows and becomes more urban and affluent, the amount of solid waste we produce grows and grows.  Over the past century, the total amount has risen tenfold.  By 2025, the world-wide total is expected to double again. The average person in the United States throws away their body weight in garbage every month.

Ugly Produce

By

Estimates are that as much as 40% of produce in America is wasted.  We throw out fruits and vegetables for a variety of reasons, but one of the most unfortunate is when produce is tossed simply because it doesn’t look good enough.   Misshapen tomatoes, lumpy carrots, double-lobed potatoes, and crooked cucumbers end up in the waste bin instead of on our plates.
