JSTOR is part of ITHAKA, a not-for-profit organization helping the academic community use digital technologies to preserve the scholarly record and to advance research and teaching in sustainable ways.
The name, JSTOR, originally meant “Journal Storage” because, to quote Wikipedia (https://en.wikipedia.org/wiki/JSTOR):
JSTOR is a digital library founded in 1994. Originally containing digitized back issues of academic journals, it now encompasses books and other primary sources as well as current issues of journals in the humanities and social sciences. It provides full-text searches of almost 2,000 journals. Most access is by subscription but some of the site is public domain, and open access content is available free of charge.
It is free if your school, library, or content is a member. Otherwise, you can get free access for a limited number of searches, but the limit is sufficiently high for many purposes.

An official journal of Tsinghua University Press (Beijing, China)
Circular Economy’ refers to all the activities of reduce, reuse, and recycle in production, circulation, and consumption. As an important route to achieving a resource-saving and environmental friendly society, ‘Circular Economy’ is becoming increasingly important both strategically and economically.
Circular Economy (CE) is an international journal serving as a sharing and communication platform for novel contributions and outcomes on innovative techniques, systematic analysis, and policy tools of global, regional, national, local, and industrial park’s waste management system to improve the reduce, reuse, recycle, and disposal of waste in a sustainable way.
Circular Economy and Sustainability
The Circular Economy and Sustainability journal aims to bring a new approach of the key concepts of circular economy and sustainability, by combining the scientific disciplines of economy, management, engineering, technology, environment, and society.
As circular economy is necessary today to promote the goals of sustainable development; these scientific areas are not independent to each other, but their relations, interactions and synergies exist and should be further developed and studied. Interdisciplinary approaches and multiple connections between these scientific areas are required not only to reach the sustainability goals but also to solve diverse environmental problems, expand technological limits and overcome potential economic disturbances.
This approach is expressed with new policies (command and control, market-based instruments, and circular public procurement), technological suggestions (e.g. technical cycle solutions), environmental engineering technologies (e.g., waste management, 3r strategies, water recycle, wastewater treatment and reuse, renewable energy), circular business models, circular innovations, circular management solutions, consumers’ behavior in circular economy, new circular economy products labels and social acceptance in circular economy.
