Household Recycling Made Easier — For a Price

I wrote about Ridwell, the Seattle startup that's building a business around collecting all the old batteries, clamshell containers and lightbulbs that most recycling programs leave behind, for Bloomberg Businessweek.   

 

Jill Fransen considers herself a serious recycler, the kind of person who knows the difference between various plastics, takes care to sort them, and drives five miles from her home in Portland, Oregon’s, North Tabor neighborhood to drop off refuse at a recycling center.

Over nearly a dozen years, Fransen’s routine was pretty well established. Then in late 2020, she heard about Ridwell, a subscription-based recycling service that had just been introduced in Portland. For about $12 per month, Ridwell would pick up items — stuff that many recycling programs won’t accept, like certain plastics and spent lightbulbs — right from one’s front porch, and take everything to its local plant to sort and redistribute for recycling or re-use.

“I was skeptical at first because of the monthly charge,” says Fransen. But seeing Styrofoam and #1 PET plastics — for polyethylene terephthalate, most known as the plastic used to make clamshell and other food containers — on Ridwell’s collection list persuaded Fransen to give it a try. “You have no idea how much #1 PET plastic you use,” she says. (According to the Michigan-based consulting firm Resource Recycling Systems, just 9% of the 1.5 billion pounds of PET-made items circulating in the U.S. are recycled.) “And driving out to East Portland got to be a pain in the neck.”

Fransen is among the nearly 300 early adopters of the service in Portland, where operations started in November 2020. Since then, the number of subscribers there has grown to 22,400. Ridwell launched and established itself first in Seattle before expanding to Portland, Bellingham, Washington, Denver, Minneapolis and Austin. The total subscribers collectively is about 60,000. The company is among a small group of environmental startups that are working to eliminate plastic packaging and create compostable plastics from mycelium, a mushroom root.

Ridwell’s growth has coincided with Americans’ redirecting much of their anxiety and restlessness over the pandemic into online shopping. That in turn has generated huge amounts of garbage. “So many people were getting stuff delivered from Amazon, Instacart, and takeout,” says Taylor Loewen, Ridwell’s Portland general manager. “People were stuck at home realizing: ‘There’s just so much packaging in my house!’”

The effort started well before the Covid pandemic. Generally, consumers don’t have many easy options for properly disposing of things like plastic film, batteries, lightbulbs, and clamshell containers. In January 2018, China banned the import of most plastic recyclables, leaving many U.S. cities without a place to send what they’d collected. Before then, processors in China had handled about half of the world’s recyclable waste. Greenpeace has estimated that more than 90% of the plastic ever produced has not been recycled.

Those types of items had accumulated in Ridwell founder Ryan Metzger’s basement in his Seattle home. One weekend in the fall of 2017, he and his then 6-year-old son Owen started to clear the house of the refuse. “Every weekend, Owen and I would pick a category — Styrofoam, batteries, lightbulbs — and we would find a local partner,” he explained — someplace willing to take the haul. Before long, Metzger, then a marketing consultant for startups, was also hauling neighbors’ expired batteries and lightbulbs to various drop-off centers and recycling facilities around Seattle, along with his own trash. He’d post messages to the  neighborhood message board Buy Nothing, sharing tips about how to get rid of stuff — “I found a place that takes Styrofoam!”

The project, initially dubbed “Owen’s List,” caught on quickly. By October 2018, with 99 customers, it was officially named Ridwell. Within a year, the subscriber list had grown to 2,400 in the greater Seattle area.

For a monthly fee of $12 to $16, depending on the length of commitment, a square white Ridwell box is collected every two weeks. The box comes with reusable cloth bags, one for each item category — batteries, lightbulbs, threads, plastic, and a rotating “featured category” which ranges from old printer cartridges to holiday lights. Metzger estimates that, as of February, over 4.6 million pounds of waste from just Seattle, Portland, and Denver have been diverted from landfills.

Finding local partners, a key piece in the project from the beginning, has helped the expansion. Metzger worked to connect with businesses and other organizations that might re-use or recycle some of the collected items. Today, Loewen, the Portland general manager, and other employees with similar roles in Ridwell’s various locations spend a good chunk of time connecting with nonprofits and organizations like Free Geek, a Portland area technology nonprofit that facilitates the reuse of small electronics. The partners and categories vary from city to city.

Four years in, the venture also has become a fuller recycling business in its own right. At Ridwell’s 10,000 square foot warehouse in northeast Portland, employees sort plastic bags and blue Amazon wrappers (recyclable) from manila padded envelopes (not recyclable). A baler is used to compress plastic film into compact bundles. Industrial-sized bins spill over with second-hand clothes which ultimately will be donated to the city’s Pioneer Wiping Cloth, one of several organizations Ridwell works with.

Ridwell’s work has drawn investor interest. Metzger says the company has received three rounds of funding, though he won’t disclose the amounts. The business, he adds, is largely customer-supported.

Dylan de Thomas is vice president for external affairs at The Recycling Partnership, a national nonprofit dedicated to improving recycling systems across the country. De Thomas, who is based in Portland, is a fan of Ridwell — with one caveat. “I think it’s a neat concept. For all the materials — minus one — it’s a convenience service,” he says, referring to PET thermoforms, which are not only not accepted by the city’s recycling program but aren’t taken by any of the free recycling centers in town, either.

An unanticipated development has been a clash with Portland trash haulers, particularly in Clackamas and Washington counties. There, the sanitation workers have protested that Ridwell is stepping on their toes, even though those municipalities don’t currently accept the items that Ridwell collects. (Portland doesn’t have a municipal sanitation department, so private companies are contracted to collect garbage.) Another big challenge has been logistics. “It’s a logistics business that is growing quickly,” Metzger says.

The Recycling Partnership’s de Thomas says ideally, what Ridwell collects and helps to redistribute or recycle should be part of any municipal service. “I prefer recycling programs that serve all of the residents equally and equitably,” he says.

Metzger is working to address the imbalance, he says, and is aware that the service Ridwell offers is not something everybody can afford. To that end, the company launched a pilot project over the December holiday season: for every gift card sold, Ridwell contributed $10 towards a six-month community-supported membership, of which there are now 100. “We hope to make it a more regular and larger part of Ridwell,” Metzger says.

Education also is part of Metzger’s game plan. The company sends out regular emails explaining what items are and are not included in each category. For example, a link might take you to the Clamshells page , which specifies that #1 PET plastic includes everything from plastic egg cartons and deli containers to plastic cookie trays. Not included in the category? Plastic bottles, blister packaging for batteries or electronics and colored plastics. Photos on each page make it easy to determine what is and isn’t included.

Last October, Metzger launched a transparency page. The company already had been sharing the names of their local partners, but on the transparency page, they also post each category’s contamination rates (how much collected material can’t be recycled or reused because it’s too dirty). On the website, you’ll learn that plastic film is the company’s most popular category in all six cities and goes to Trex in Nevada, where it’s transformed into composite decking.  Also that batteries, which go to EcoLights, have the highest recycling rate: 100%. 

“Transparency is something that consumers are very interested in,” Metzger says.  “It reinforces the behavior they’re making and shows the impact that we can all have by recycling and reusing properly.”

California’s Floodplains Are Coming Back, and So Are Their Salmon

Farmers and ecologists are partnering to restore the state’s natural flooding patterns, allowing native fish to thrive.

I wrote this story for Reasons to be Cheerful. 

Until just a couple of centuries ago, inland California was a lush tapestry of wetlands and floodplains that nourished a thriving ecosystem of fish. But as the state — and its vast agriculture industry — has grown, its waterways have been modified drastically. Rivers have been drained, fields dried out, levees and dams constructed. These engineering feats, coupled with extreme drought, have decimated natural habitats. Today, a shocking 83 percent of native fish species in the state are in decline.

Chinook salmon is one of these. “Winter runs used to have returns in the hundreds of thousands. Now a good year would be 10,000 fish,” says Andrew L. Rypel, a professor of fish ecology at UC Davis where he co-directs the Center for Watershed Sciences. Today, two of California’s three recognized Chinook salmon runs are listed under the U.S. Endangered Species Act. “We have had years that have just been in the hundreds. It’s a species on the precipice of extinction.”

Now, Rypel and his colleagues are helping the Chinook rebound by working with California rice farmers to recreate the natural floodplains in which the fish used to thrive.

The so-called “salmon-rice project” began a decade ago, when a motley group of scientists, rice farmers and conservationists joined together to answer a simple question: if they were to flood rice fields with water from the Sacramento River — effectively mimicking the region’s original ecological rhythms — would juvenile salmon take to the fields and grow? 

First, they conducted some basic experiments to see whether salmon even lived in floodplains. Turns out, they did. The Nigiri Project – which began in the early 2000s, is still ongoing and involves some of the same people working on Rypel’s project — set out to determine whether salmon can survive on rice fields. In Asian countries, freshwater fish are often raised on flooded rice paddies, but it wasn’t known if salmon in particular were suited to that environment.

“The answer was that they not only survive, they grow extremely well,” Rypel says. “The fish were feeding on lush zooplankton that develop off the decomposed rice straws.” Rice straw is a rich source of carbon, and Rypel says that the density of zooplankton (normally microscopic) that develops in these winter-flooded rice plains is so high that you can actually see them with the naked eye, swimming around. 

“It turns out that this kind of food is like an awesome steak for the growing salmon,” he says. UC Davis scientists found that these juvenile salmon survived at high rates in the flooded rice fields — 50 to 80 percent over the course of a month. “That’s excellent for baby fish,” Rypel says. They also grew two to five times faster than they grow in the Sacramento River.

With these data points in hand, Rypel and his colleagues teamed up with the California Rice Commission and California Trout in 2018 and began studying the viability of raising juvenile salmon in small experimental fields. The work was funded, in part, by the Natural Resources Conservation Service (NRCS), a wing of the United States Department of Agriculture that pays farmers and ranchers to do conservation work.

In 2021 the California Rice Commission and the UC Davis scientists got an additional $550,000 grant from NRCS to continue and expand upon their work. (The California Rice Commission and its partners are matching this grant.) Though this is the first year scientists are trying this out on production-scale rice farms, preliminary data is encouraging. For instance, in years like the past one, when the rice fields around the Sacramento River don’t flood naturally, farmers flood their fields with water from the adjacent canals and then scientists stock them with hatchery fish. They then track the fishes’ growth, survival and movements. Data so far indicates that these fish survive at a rate four to five times higher than lab-raised fish. 

In the coming months, they’ll continue to track these hatchery salmon with tiny acoustic transmitters as they make their way out to sea. “One of the critical parameters that salmon managers are interested in is out-migration survival,” Rypel says. “That is: do they make it to the ocean? And how many?” The plan is to track 600 of the salmon to see if they make it to the Golden Gate Bridge and conduct a side-by-side comparison with lab-reared fish of out-migration survival.

 

Rypel says it boils down to two words: Big and early. “Being a baby salmon kind of sucks!” he laughs. “It’s really hard. Most of the fish die. You are dodging predators, you have to migrate a super-long distance. You need fat reserves.” Giving the salmon a head start while they’re still very young can have huge knock-on effects. “We think that by rearing them on these rice fields, we can get fish very big, very quick. If the fish can become smolts [juvenile salmon] earlier in the winter, they can ride the flows better and have better survivorship.”

Raising fish in rice paddies is nothing new. Rice farmers from China, Thailand, India and Northern Vietnam have been doing it for centuries – according to some evidence, for as long as 2,000 years.

But the project in California is actually more directly inspired by a series of bird conservation efforts dating back to the late 1980s and early ’90s. At the time, Pacific flyway birds — ducks, snow geese, egrets and all the other migratory birds that over-summer up in Alaska or Canada, and over-winter in the Central Valley — were in decline. For decades, rice farmers in the area regularly burned their leftover rice straw after the fall harvest. “People who lived in the area at that time will remember when the skies were black with smoke,” Rypel says. The air quality was poor, and carbon was being released into the atmosphere, as well.

Residents frustrated by poor air quality campaigned to stop this practice, and in 1991 a state law banned it. “Some smart people got together at that time and figured out that if you re-flooded the rice fields, you could naturally decompose the rice straw,” Rypel says. “At the same time, you could potentially provide habitat for the migratory birds that were on the Pacific flyway.” The NRCS began a program where they paid rice farmers to flood their fields instead of burn them, which was a win for the locals, a win for the birds and a win for the farmers, as it gave them a new revenue stream.

“I’m not a bird ecologist, but I work with a lot of bird scientists who have worked on this, and it’s probably one of the big conservation success stories in our country’s history,” Rypel says.

It was that program’s success that got fish ecologists scratching their heads. “Hey, if you can do this for birds, why can’t you do that for fish?” Rypel recounts. “We’ve got 83 percent of species declining in California. We know salmon use the floodplains. Is there a way to do this with fish?” 

The answer appears to be a resounding yes. There are roughly 500,000 acres of rice under cultivation in the Sacramento Valley. “That’s a lot of habitat that’s potentially on the table there,” notes Rypel. He and his colleagues at UC Davis hope to replicate the model on more farms in years to come. “It’s a good example of how farms can work together with conservation scientists to make a difference.”
