Curbing food waste

February 3, 2025 By EarthWise Leave a Comment

Efforts to curb food waste are failing

According to the U.S. Department of Agriculture, as much as 40% of the food supply in the United States is wasted.  In fact, Americans generate more food waste than all but two countries.

To address this problem, the federal government announced a goal nearly a decade ago to cut food waste in half by 2030 compared to 2016 levels.  Doing so would bring food waste down to approximately 164 pounds per person annually.

However, according to a new study led by researchers from the University of California – Davis, since 2016, per capita food waste has actually increased instead of decreasing. 

The study, which was recently published in the journal Nature Food, looked at how state policies align with federal targets.  The research team found that state policies focus more on recycling methods, such as composting and anaerobic digestion, rather than on prevention and rescue strategies, like food donations or repurposing food for animal feed.

In 2021, the EPA revised its definition of food waste to no longer include recycling methods.  But when food is wasted, the resources used to grow the food, including energy, water, and fertilizer, are also wasted. 

In the study, the researchers analyzed state-level food waste reduction efforts across four areas: prevention, rescue, repurposing, and recycling.  They found that recycling policies offered the most potential for diversion. Despite this, most states still fell short of the federal goal of 164 pounds per person annually. 

According to the research team, more comprehensive policies to address food waste must be implemented as soon as possible.

Halloween pumpkins

October 28, 2024 By EarthWise Leave a Comment

According to the National Retail Federation, spending on Halloween festivities this year by the 72% of Americans who plan to celebrate is expected to total $11.6 billion – or about $104 per person.  The annual consumer survey also found that 67% of Americans plan to pass out candy this year, and nearly 50% of Americans plan to carve a pumpkin.

To produce enough pumpkins for Halloween, farmers grow lots of them every year.  In fact, more than two billion were grown in 2020 alone.  But the vast majority of pumpkins are never eaten; instead, most are carved and placed on porches across the country.  This means Americans spend hundreds of millions of dollars on pumpkins annually just to toss them in the trash when Halloween ends. 

When pumpkins are placed in landfills, they produce methane gas.  Methane is a potent greenhouse gas that affects climate change by contributing to increased warming. 

Instead of throwing pumpkins into the landfill, there are several responsible ways to dispose of them. 

If the pumpkin is still in good shape, use the outer, meaty part of the pumpkin to make pumpkin puree.  The pumpkin seeds can also be scooped out, rinsed, seasoned, and then baked in the oven, resulting in a delicious snack.

Pumpkins also have the potential to turn into great soil through composting. Pumpkins can help naturally add moisture to compost piles that need to be damp in order 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.

A billion pound problem

November 1, 2023 By EarthWise 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.

An Indoor Farm In Upstate New York | Earth Wise        

March 11, 2022 By EarthWise Leave a Comment

Indoor farms to help feed the world

Vertical farming is the practice of growing crops in vertically stacked layers, generally under controlled environments and using soilless farming techniques like hydroponics, aquaponics, and aeroponics.   Vertical farms are housed in structures such as buildings, shipping containers, tunnels, and abandoned mineshafts.

The potential advantages of vertical farms are that they are very efficient in terms of the amount of land required to produce a given amount of crop, they are resistant to weather, and they allow crops to be produced in close proximity to where they will be used.

The vacant third floor of a building in downtown Glens Falls, New York is about to become the home of a small vertical farm.  The facility will be used to hydroponically grow things like fresh basil, lettuce, and fruits to be used by nearby restaurants.  In fact, the first floor of the building is a restaurant that will be a customer for the crops growing upstairs.  Other local restaurants are likely to benefit as well.

Th pilot program is being funded by a grant from the Smart Cities Innovation Partnership that the city applied for in 2020.  Glens Falls is partnering with Re-Nuble, a New York City-based renewability and sustainability firm.  Apart from the vertical farm project, Re-Nuble also advises on reduction of food waste by composting and on the selection of energy-efficient equipment.

The pilot program will run for a year and the results will be used for scaling it up to a larger vertical farm.  Vertical farms like these are not intended to replace conventional farms but can supplement the existing food stream and provide items that are hard to obtain during the year.

According to the United Nations World Tourism Organization, more than one billion international tourists travel the world each year.  Tourism has become a powerful and transformative force for many millions of people.  But all this travel is not as positive for the planet.  To that end, the luxury travel network Virtuoso assembled a short, simple list everyone can follow to reduce the environmental impact of their travel.

Stop Putting Food Waste Down The Drain

Should we really be putting food scraps down our sinks? Advertisements for kitchen garbage disposals assure us that these devices are a ‘hygienic way of eliminating waste and keeping odors at bay’ – but behind marketing materials questions remain.
