We Now Have a Chance to Get Serious About Recycling

The plastic waste crisis is an opportunity for the U.S. to rethink its approach to recycling

A global plastic waste crisis is building, with major implications for health and the environment. Under its so-called “National Sword” policy, China has . As a result, piles of plastic waste are building up in ports and recycling facilities across the United States.

In response, support is growing for banning or restricting single-use consumer plastics, such as straws and grocery bags. These efforts are also spurred by chilling findings about how micro-plastics travel through oceans and waterways and .

I have for many years and am currently completing a book on the global politics of waste. In my view, today’s unprecedented level of public concern is an opportunity to innovate. There is growing interest in improving plastic recycling in the United States. This means getting consumers to clean and sort recyclables, investing in better technologies for sorting and reusing waste plastics, and creating incentives for producers to buy and use recycled plastic.

Critiques of recycling are not , and critiques of recycling plastic are , but I still believe it makes sense to expand, not abandon, the system. This will require large-scale investment and, in the long term, implementing upstream policies, including product bans.

Easy to use, hard to destroy

Plastics make products lighter, cheaper, easier to assemble, and more disposable. They also generate waste, both at the start of their life cycles — the petrochemicals industry is a major source of pollution and greenhouse gas emissions — and after disposal.

The by far for plastic resin is packaging (34% in 2017), followed by consumer and institutional goods (20%) and construction (17%). Many products’ useful lives can be measured in minutes. Others, especially engineered and industrial plastics, have a longer life — up to 35 years for building and construction products.

After disposal, plastic products take anywhere from to break down. Many degrade into micro-plastic fragments that effectively last forever. Rather like J.R.R. Tolkien’s , plastics can be permanently destroyed only through incineration at extremely high temperatures.

Why the U.S. recycles so little plastic

of discarded plastics entered the recycling stream in the United States in 2013, compared with in the European Union and in China. Another 15% of U.S. plastic waste is burned in waste-to-energy facilities. The remaining 75% goes to landfills. These figures do not include any dumping or illegal disposal.

Even the most easily recyclable plastics have a lengthy journey from the recycling bin to their final destinations. Many barriers have become painfully apparent since China, which until recently accepted half of all U.S. plastic scrap, implemented its crackdown on March 1 of this year.

First, there are many different types of plastics. Of the seven resin identification codes stamped on the bottom of plastic containers, only 1s and 2s are easily recyclable. Public education campaigns have lagged, particularly with respect to cleaning and preparing plastics for recycling. Getting consumers to commit to more stringent systems is critical. But scolding , as experience with food waste shows.

Another factor is U.S. reliance on , in which all recyclables are placed in the same receptacle. This approach is easier for consumers but produces a mixed stream of materials that is difficult and expensive to sort and clean at recycling facilities.

The United States currently has , which can clean, sort, and bale a total of 100,000 tons of recyclables per day. Today they are under growing pressure as scrap piles up. Even before China’s restrictions went into effect, materials recycling facilities operators threw out around half of what they received because of contamination. Most are not equipped to meet China’s stringent new contamination standards, and their processing rates have slowed – but garbage production rates have not.

Finally, since China was the U.S. plastic scrap market’s main buyer, its ban has eliminated a key revenue stream for municipal governments. As a result, some waste collection agencies are suspending curbside pickup, while others are raising prices. All have been affected to some extent.

There are no silver bullets

Numerous public and private entities are working to find a more viable solution for plastics recycling. They include plastics and , corporations such as , , , , , and .

Upgrading materials recycling facilities and expanding domestic markets for plastic scrap are obvious priorities but will require large-scale investments. Increasing waste-to-energy incineration is another option. relies on this approach to maintain its zero waste model.

But incineration is deeply controversial in the United States, where it has since 2001, partly due to strong opposition from host communities. Zero-waste and anti-incineration advocates have initiatives such as the , a recent pilot initiative in Omaha, Nebraska, to divert plastics to energy production. But small companies like Salt Lake City-based are working to develop newer, cleaner ways to convert plastics to energy.

Efforts to cut plastic use in the United States and other wealthy countries are . Initiatives such as and build awareness, but may not by themselves significantly reduce the problem of plastic trash. For example, plastic straws account for only 0.03%  of the plastic that is likely to enter the oceans in any given year.

Industry is starting to , with corporations like resisting straw bans. Some U.S. states have passed measures .

To stem ocean plastic pollution, is critical, including steps to combat illegal dumping and manage hard-to-recycle plastics. Examples include , dechlorinating products, on-site , and making out of used polypropylene.

The European Union is developing a that contains a multi-part strategy to increase plastics recycling and control waste. It includes making all plastic packaging recyclable by 2030 and reducing leakage of plastic products into the environment. The United States is unlikely to adopt such sweeping policies at the national level. But for cities and states, especially those where support for environmental protection is strong, it could be a more attainable vision.

    Make recycling a tax-exempt business. Start taxing plastics with an informed rate structure that penalizes single use and rewards the recycle uses. I am sure there are many more ways to get plastic recycling going in the US.
