A new study found Maine households are a leading contributor of food waste in local landfills, which in turn contributes to climate change.

Researchers said as the waste breaks down, it produces methane, a potent greenhouse gas.

Susanne Lee, faculty fellow for the Sen. George J. Mitchell Center for Sustainability Science at the University of Maine, said reducing food waste is one of the easiest ways to solve the problem.

"Not everybody can get a new electric vehicle but everybody can shop more wisely, do meal planning," Lee pointed out.

Lee noted new data on where and how food waste is generated will be added to the state's climate plan. She argued it could help in building the needed infrastructure to transport, store and distribute excess food from farms and businesses. About one in eight Mainers experienced food insecurity in 2022, including one in five children.

A recent pilot program helped four elementary schools in Maine reduce their food waste by up to 20% while improving kids' nutrition. Students learned about waste in landfills and got a close-up look at their own waste by sorting their scraps and trash. Lee believes early education programs will be key to helping Mainers build sustainable habits and ensure the state reaches its own climate goal of net-zero emissions by 2045.

"A simple 10-minute explanation of how food is meant to be nutritious and not meant to be trash," Lee explained. "These children can get it."

Lee added new funding will allow researchers to continue the elementary school programs and even follow one school's students into middle school to see if their new habits stick. Legislators are also considering an outright ban on food waste in landfills, something already enacted in every other New England state.

California receives high marks in a report on the fight against plastic pollution. This is Plastic-free July and the United States of Plastics report, from Ocean Conservancy, awards the Golden State a score of four-and-a-half out of five.

Report co-author Anja Brandon, director of plastics policy with Ocean Conservancy, largely credits Senate Bill 54, California's landmark law passed in 2022.

"It holds plastic and other packaging producers financially responsible for managing their wasteful products. And it requires that producers make 25% less single-use plastics by 2032," she said.

The state also banned most plastic grocery bags a few years ago. Starting next year, the thicker plastic bags now sold at checkout stands will also go away. Shoppers will have to go back to using paper bags or bring reusable cloth bags.

Brandon noted California still has more work to do, adding the state has been slow to implement SB 54's ban on expanded polystyrene foam, which was supposed to take effect last January.

"The state agencies finally issued guidance and an enforcement portal, literally this week. So it's seven months late, but they are finally getting around to enforcing that critical component of the law," she continued.

The report also found California is the only state with a law directly addressing pollution from pellets used to manufacture plastics.

California companies making compostable packaging materials said their products could make a huge dent in the problem of plastic pollution but only with changes to state and federal policy.

California passed Senate Bill 54 in 2022. It requires single-use packaging and plastic foodware to be either recyclable or compostable by 2032. The issue is with a companion bill, Assembly Bill 1201, which said compostable materials must be certified organic.

John Felts, cofounder and CEO of Santa Cruz-based Cruz Foam, which makes compostable packaging foam from food waste, said the requirement is a tall order.

"The idea that all compostable packaging would have to comply, would effectively remove compostable packaging from being viable," Felts explained. "The cost, the tracking, making a fully certified organic packaging material is nearly impossible."

The organic requirement is set to go into effect Jan. 1, but negotiations are underway in Sacramento to delay implementation, a move also supported by the plastics industry. Environmental advocates said plastic waste is choking the planet, disrupting marine ecosystems, and endangering human health, so recycling, reusable containers and compostable packaging are key.

It is estimated 40% of plastic produced today is used to make packaging, much of which is used once.

Julia Marsh, cofounder and CEO of San Leandro-based Sway, which uses seaweed to make flexible packaging, said plastic use is only increasing.

"About 5 trillion bags, wrappers and pouches are produced every year; 11 million metric tons of plastic enter the ocean every year," Marsh pointed out. "That number is expected to triple by 2040, if production rates continue as is."

Advocates would also like the National Organic Program within the U.S. Department of Agriculture to broaden the term "organic" to include certified compostable materials.

A lot of households might have junk piles on their kitchen counter or an overflowing storage room. A North Dakota expert says to avoid stress that comes with clutter, there are skills to gain in tidying up.

According to AARP, a more organized and simplified living space can reduce stress, improve mental clarity and create a safer environment.

Deb Mathern is a volunteer with AARP North Dakota who offers guidance as part of the group's Speakers Bureau. She said she subscribes to an "equal-in, equal-out" theory.

"When you're out shopping, your house doesn't grow," said Mathern. "So, when you bring home that carload of stuff that you just purchased, it might be time to take out a couple things."

She said she understands it can be difficult to let go of things because people work hard to buy them.

Cherished family treasures can be kept in a box or specific area. Otherwise, she suggested donating items you really don't wear or use anymore.

For older populations who haven't downsized yet, she warned that extra piles create tripping hazards.

Mathern said when out shopping, it's OK to occasionally buy something that might bring you excitement and joy. But she recommends thinking first about how long you might keep it, and avoid falling into an unwanted pattern of loading up your cart.

"I think it fills an emotional void for a lot of people," said Mathern, "and that's the wrong reason to be buying."

As for older residents planning to move into a smaller space, she recommends measuring the size of bigger household items to figure out if they'll fit in the new home. She said if they won't, you might save on moving costs by leaving them behind if they won't be used much.

Lastly, she suggests not renting storage spaces for too long, because most of the contents just collect dust without being pulled out.
