The mass production and disposal of non-degradable fossil-based plastics is responsible for alarming environmental and social issues when not managed responsibly. Towards manufacturing environmentally-friendly materials, biopolymers, that is, polymers synthesized by living organisms, emerge as promising sustainable alternatives as they combine attractive mechanical properties, compostability, and renewable sourcing.
In the next year, the EPA could make a final decision on whether to classify PVC as hazardous waste. What would this entail? Fellow Rachel Meidl explores why a hazardous designation for PVC would have costly implications — moving the U.S. further from its goal of achieving a sustainable, circular economy.
The authors write that enormous volumes of “energy transition waste” — waste from wind turbines, solar panels, lithium-ion batteries, etc. — are anticipated in the coming decades. To cope with this waste and ensure a sustainable energy transition, they call for more data, planning and coordination across the entire global supply chain, in addition to waste management and recycling policies that align with environmental and sustainability goals.

"With the pressures of climate change and the urgency to incorporate alternative energy resources like wind and solar, the fixation on the purported benefits of energy transition technologies overshadows the glaring reality — an absence of strategy around identifying and quantifying other life cycle externalities, such as waste disposal or environmental impacts," write fellow Rachel Meidl and research assistant Mathilde Saada.

Recycling solar panels is an expensive, complicated and energy-intensive process, writes energy fellow Rachel Meidl. But with cumulative solar waste projections expected to rise globally over the next few decades, she argues that it is vital to design a more circular and sustainable management system for end-of-life panels.
In the push for decarbonization, "turquoise" hydrogen offers a unique, commercially viable technology that reduces CO2 emissions, argue Rachel A. Meidl and Kenneth B. Medlock III.

Circular processes cannot solve the sustainability problem, but critically implementing circularity with system-level thinking can help to urgently adopt a more resilient, regenerative model for avoiding resource scarcity while fostering economic growth, argues a Forbes piece co-authored by Rachel Meidl.

Circular economy principles are oftentimes used in conjunction or synonymously with the term “sustainability.” However, although there is a relationship between sustainability and circularity, these two concepts are very different. Energy fellow Rachel A. Meidl explains the distinction in a new post for the Baker Institute Blog.
The term “sustainability” is a frequently misconstrued descriptor, oftentimes used synonymously with the concept of a circular economy. In this issue brief, energy fellow Rachel Meidl explains the distinction between circularity and sustainability and how a systems-level approach to waste management can build an economy that is resilient to future global disruptions.
