Every week, millions of Americans toss their recyclables into a single bin, trusting that their plastic bottles, aluminum cans, and cardboard boxes will be given a new life.

But what really happens after the truck picks them up?

Single-stream recycling makes participating in recycling easy, but behind the scenes, complex sorting systems and contamination mean a large percentage of that material never gets a second life. Reports in recent years have found 15% to 25% of all the materials picked up from recycle bins ends up in landfills instead.

Plastics are among the biggest challenges. Only about 9% of the plastic generated in the U.S. actually gets recycled, according to the Environmental Protection Agency. Some plastic is incinerated to produce energy, but most of the rest ends up in landfills instead.

So, what makes plastic recycling so difficult? As an engineer whose work focuses on reprocessing plastics, I have been exploring potential solutions.

How does single-stream recycling work?

In cities that use single-stream recycling, consumers put all of their recyclable materials − paper, cardboard, plastic, glass, and metal − into a single bin. Once collected, the mixed recyclables are taken to a materials recovery facility, where they are sorted.

First, the mixed recyclables are shredded and crushed into smaller fragments, enabling more effective separation. The mixed fragments pass over rotating screens that remove cardboard and paper, allowing heavier materials, including plastics, metal,s and glass, to continue along the sorting line.

Magnets are used to pick out ferrous metals, such as steel. A magnetic field that produces an electrical current with eddies sends nonferrous metals, such as aluminum, into a separate stream, leaving behind plastics and glass.

The glass fragments are removed from the remaining mix using gravity or vibrating screens.

That leaves plastics as the primary remaining material.

While single-stream recycling is convenient, it has downsides. Contamination, such as food residue, plastic bags and items that can’t be recycled, can degrade the quality of the remaining material, making it more difficult to reuse. That lowers its value.

Having to remove that contamination raises processing costs and can force recovery centers to reject entire batches.

Which plastics typically can’t be recycled?

Each recycling program has rules for which items it will and won’t take. You can check which items can and cannot be recycled for your specific program on your municipal page. Often, that means checking the recycling code stamped on the plastic next to the recycling icon.

These are the toughest plastics to recycle and most likely to be excluded in your local recycling program:

• Symbol 3 – Polyvinyl chloride, or PVC, found in pipes, shower curtains, and some food packaging. It may contain harmful additives such as phthalates and heavy metals. PVC also degrades easily, and melting can release toxic fumes during recycling, contaminating other materials and making it unsafe to process in standard recycling facilities.
• Symbol 4 – Low-density polyethylene, or LDPE, is often used in plastic bags and shrink-wrap. Because it’s flexible and lightweight, it’s prone to getting tangled in sorting machinery at recycling plants.
• Symbol 6 – Polystyrene, often used in foam cups, takeout containers, and packing peanuts. Because it’s lightweight and brittle, it’s difficult to collect and process and easily contaminates recycling streams.

Which plastics to include

That leaves three plastics that can be recycled in many facilities:

• Symbol 1 – Polyethylene terephthalate, or PET, widely used in soda bottles.
• Symbol 2 – High-density polyethylene, or HDPE, commonly used in milk jugs and laundry detergent bottles.
• Symbol 5 – Polypropylene, PP, used in products such as pill bottles, yogurt cups and plastic utensils.

 Many Americans might not have felt major effects from President Donald Trump’s sweeping tariffs — until now.

That’s because a major shipping loophole expired at one minute past midnight on Friday. The de minimis exemption, as it’s known, allowed shipments of goods worth $800 or less to come into the United States duty-free, often more or less skipping time-consuming inspections and paperwork.

The loophole helped reshape the way countless Americans shop, allowing ultra-low-cost Chinese e-commerce sites like Shein, Temu and AliExpress to pour everything from yarn to patio furniture, clothes to photography equipment and more into US homes.

Its impending end has rung alarm bells across social media, with a baseline tariff as high as 145% depending on the carrier set to take effect on Chinese imports, potentially more than doubling the cost for all those cheap products deal-hungry Americans scooped up.

And the end of the de minimis exemption for Chinese goods will also distill abstract, complicated, messy, hard-to-follow trade policy into something much easier to understand: a receipt.

Major carriers like UPS, FedEx, DHL, and the United States Postal Service say they’re prepared for the changes. The government says it, too, is set; a US Customs and Border Protection spokesperson told CNN that “We are prepared and equipped to carry out enhanced package screenings and enforce orders effectively.”

But whether regular American shoppers are ready for the changes is another matter.

Of tchotchkes and trade policy

When President Donald Trump initially closed the de minimis exemption for goods from Hong Kong and China earlier this year, chaos ensued.

USPS briefly stopped delivering parcels from China. Delivery times for parcels that did get shipped stretched longer, with limited information on package tracking in the US.

At the heart of the issue: the sheer volume of packages. More than 80% of total US e-commerce shipments in 2022 were de minimis imports, the vast majority of which come from China, according to a congressional research report.

CBP told CNN it currently processes “nearly 4 million duty-free de minimis shipments a day.” Research indicates that a majority of those shipments come from China and Hong Kong. In total, over the last fiscal year, CBP said 1.36 billion packages came to the US under the de minimis exemption.

That’s a lot of dog bandanas, bead kits, frosting spatulas, and tchotchkes. Regular Temu and Shein shoppers told CNN this week they’ve increasingly turned to the site as they feel made-in-the-USA products have gotten out of reach.

“I can’t afford to buy from Temu now, and I already couldn’t afford to buy in this country,” Rena Scott, a 64-year-old retired nurse from Virginia, previously said to CNN Business.

Lower-income households will suffer the most from the end of cheap Chinese e-commerce sites. About 48% of de minimis packages shipped to the poorest zip codes in the United States, while 22% were delivered to the richest ones, according to February research from UCLA and Yale economists.

The changes could come in stages. Already, for example, Shein and Temu raised prices ahead of the de minimis exemption’s end, hiking prices on several goods tracked by CNN 

“Due to recent changes in global trade rules and tariffs, our operating expenses have gone up. To keep offering the products you love without compromising on quality, we will be making price adjustments,” Shein said in a notice posted online recently. “We’re doing everything we can to keep prices low and minimize the impact on you.”

A Temu spokesperson said the company was changing its business model to encourage more local fulfillment, growing the number of US sellers on the platform.

Narcissistic leaders both fascinate and repel us. They can be charming, act assertively, and articulate visions that may inspire confidence, especially in times of uncertainty. This can attract many followers. In 1931 Sigmund Freud, the father of psychoanalysis, echoed this belief: “[Narcissists] impress others as being ‘personalities’; they are especially suited to act as a support for others, to take on the role of leaders and to give a fresh stimulus to cultural development or to damage the established state of affairs.”

But narcissists famously have a dark side as well that includes unethical, autocratic, and aggressive behavior. They often stifle collaboration and dismiss expert advice. Given those trade-offs, why do narcissists often end up in positions of leadership, and who is drawn to them? My colleague Barbara Nevicka, an organizational psychologist at the University of Amsterdam, and I set up the Childhood Leadership Study to investigate this question in childhood, when narcissistic leadership first emerges. We conducted fine-grained assessments of leadership behavior in 332 children aged seven to 14—and found patterns both in the preference for these leaders and in the relationships that leaders and followers form.

Narcissism is a personality trait characterized by feelings of grandiosity, a sense of entitlement, and a craving for respect and admiration. It’s part of what psychologists call the “dark triad” of personality traits—along with psychopathy and Machiavellianism, or cold, strategic manipulation for personal gain. In adulthood, narcissism may develop into a narcissistic personality disorder. About 6 percent of people in the U.S. meet the criteria for this disorder at some point in their lives, though they may not receive a formal diagnosis. Our research focuses on children with above-average narcissism levels because narcissistic personality disorder is usually not formally diagnosed before adulthood.

The personality trait of narcissism develops in childhood and can be measured from middle childhood, around age seven. Although some degree of narcissism is typical in children this age, markedly higher levels compared with peers may signal a narcissistic personality. Middle childhood is also when leadership tendencies take shape and become increasingly evident. From age nine, children spend about 75 percent of their free time at school in groups of three or more peers, allowing them to form leader-follower relationships. Leadership on the playground, then, provides a blueprint for leadership in politics and beyond.

Our study shows that narcissistic children often emerge as leaders in their classrooms. When we asked children to nominate classmates who they perceived to be leaders, kids in 96 percent of the classrooms tended to pick children with more narcissistic tendencies. It seems that narcissistic children embody the qualities their peers associate with leadership.

But are narcissistic children better leaders? We assigned children to three-person groups and randomly designated one child as the leader to find out. The groups did a collaborative task, with the leader responsible for the decision-making process. Unsurprisingly, more narcissistic children perceived themselves as better leaders. Yet compared with their less narcissistic peers, they did not lead their group to perform better, exhibit stronger leadership (such as by delegating tasks), or receive higher ratings from their group members.

This finding ties in with research among adults. A meta-analysis by Emily Grijalva, an organizational psychologist at the University at Buffalo, shows that narcissistic adults tend to emerge as leaders but don’t excel in those roles.

We suspected that narcissistic traits in leaders are more attractive to some people than others. So we zoomed in on children with low self-esteem—those who feel unsatisfied with themselves and are often shy and withdrawn. We found that when followers with low self-esteem had a narcissistic leader, they perceived the leader as more effective and were more likely to endorse them for future leadership roles than did their peers with higher self-esteem. What’s more, they felt more included in the group, perceived greater group cohesion, felt better about themselves, and were more inclusive toward others when they had a narcissistic leader.

The market volatility experienced in early April may have left some investors feeling a bit unnerved.

While many tried-and-true strategies, such as “stay the course,” are still relevant today, there are three additional strategies available to investors that may help take the sting out of lower retirement and investment balances.

1. Retirees: Turn off systematic withdrawal plans

Many retirees use systematic withdrawal plans (SWPs) to generate monthly income. These plans automatically liquidate a specified dollar amount of mutual fund investments and deposit the cash proceeds into a money market or other interest-bearing account.

In most markets, these arrangements work fine, but during a sharp market decline, retirees must be wary of “reverse dollar-cost averaging.” Lower mutual fund values mean an increasing number of units need to be sold to generate the specified amount of monthly income.

As a result, when the markets recover, there are fewer units participating in future appreciation.

We suggest pausing these programs for now and taking a deliberate approach to generating cash flow. Consider that the Bloomberg US Aggregate Bond Index, which is a common benchmark used to evaluate the bond market, has a positive year-to-date return through April 16, 2025.

Retirees in need of monthly income may be well served by cashing in a larger portion of bond investments, giving stock investments that may be struggling more time to recover.

At first glance, this strategy may sound counterintuitive because it creates a more aggressive asset allocation at a time when most retirees are looking to derisk their portfolios.

To be clear, a wholesale change to individual portfolios is not what we are recommending. Rather, investors may want to consider a short-term fix to avoid selling stocks at the worst possible time — immediately after they have dropped in value.

Of course, if the markets begin to decline rapidly again, more drastic measures may be necessary to ensure sustainable cash flow throughout one’s lifetime.

2. Wealth accumulators: Cherry-pick specific investments for Roth conversions

Investors who are saving for retirement may have a traditional IRA or an employer-sponsored retirement plan such as a 401(k) or 403(b). When these balances are substantially lower may be an ideal time to consider a Roth conversion.

Conversions trigger an immediate income tax liability, but the future growth accumulates income tax-free.

Importantly, the Roth IRA conversion does not have to be an all-or-nothing decision. In fact, investors can choose the portion of the account and, in most cases, the specific securities they wish to convert.
