The Cure for Disposable Plastic Crap Is Here—and It’s Loony

🌈 Abstract

The article discusses the environmental problem of single-use plastics and explores various approaches to reducing plastic waste, including:

Developing compostable bioplastic alternatives made from materials like seaweed
Improving plastic recycling systems, as exemplified by Norway's successful bottle recycling program
Implementing reusable container systems, such as the one developed by the startup Reusables

The article highlights the challenges and potential solutions in tackling the plastic pollution crisis from multiple angles.

1. What are the key features of the bioplastic developed by the startup Sway?

Sway is developing a bioplastic made from seaweed that is designed to be compostable at home, unlike many existing bioplastics that require industrial composting facilities.
The Sway team is working to make the bioplastic melt and stretch more easily to match the performance of traditional plastic bags.
Sway has partnered with companies like Eco-Enclose, Burton, and J.Crew to use their bioplastic in packaging applications.

2. What are some of the challenges and criticisms faced by Sway's bioplastic technology?

Sway is still working to improve the melting and stretching properties of their bioplastic to match the performance of traditional plastic.
There are doubts about whether bioplastics can be reliably composted, and concerns about the potential environmental impacts of scaling up seaweed farming.
Sway acknowledges these critiques and sees their mission as addressing these concerns with their bioplastic formulation.

1. How has Norway achieved such high plastic bottle recycling rates?

Norway passed a law that required beverage companies to pay a tax if they did not collect and recycle a high percentage of the plastic bottles they sell.
This incentivized the companies to create Infinitum, a system that collects bottles through a network of reverse vending machines and ensures the bottles are properly recycled.
Infinitum also worked with companies to standardize bottle designs to simplify the recycling process.

2. What are the limitations of a closed-loop recycling system for plastic bottles?

Even with repeated recycling, the quality of PET plastic bottles gradually degrades, requiring the addition of virgin plastic to maintain performance.
Recycling other types of plastics, such as food containers, is more challenging due to the complex mix of materials used.
Critics argue that plastic recycling in the US will never reach high rates without stronger government policies and penalties, as seen in Norway.

1. How does the Reusables system work to reduce single-use takeout containers?

Reusables provides reusable stainless steel and silicone containers that customers can use for takeout meals and return to participating restaurants and stores.
The containers are tracked using QR codes or RFID tags, and customers are charged a fee if they don't return the containers.
Reusables has partnered with universities and some Canadian grocery stores to implement this reuse system.

2. What are the key factors that enable the success of reusable container systems like Reusables?

Making the system as convenient as possible for customers, so they don't have to change their behavior significantly.
Securing buy-in from businesses and governments to mandate the use of reusable containers and provide the necessary infrastructure.
Designing the system with features like automated return bins to streamline the process for customers.
