The purpose of this Phase I project was to develop a process for recovery of chromium from spent chromium(III) oxide fluorination catalysts and similar waste or byproduct streams. The spent catalysts contain 40-64% chromium, primarily in the forms of chromium(III) oxide, Cr2O3, and chromium(III) fluoride, CrF3. They are hazardous solid wastes, for which no known processes for chromium recovery had previously existed. Little has been reported on the chemistry of chromium(III) fluoride. Work in our laboratories has shown that the spent catalysts are extremely inert to chemical attack by...

"The European Commission's 2014 Communication on Resource Efficiency Opportunities in the Building Sector identified the need for a common EU framework of indicators for the assessment of the environmental performance of buildings. A study to develop this approach is being taken forward during 2015-2017 by DG ENV and DG GROW, with the technical support of DG JRC-IPTS. This working paper brings together the findings of the first stage in this study, which focusesses on the identification of 'macro-objectives' for the environmental performance of the EU buildings stock. This stage is...
A press release by Philips announcing a partnership with Schiphol Airport in Amsterdam to provide light as a service. The release claims that the fixtures now being used are more sustainable and energy efficient. The statement explicitly states the partnership as a step towards a more circular economy
The article seeks to define the concept of Product Service Systems (PSS) and then explain its economic, environmental, and other real world impacts. The main purpose of the piece is to explain these concepts through describing the application of the PSS to a real world scenario in the manufacturing sector in the UK
"A New Dynamic makes the contemporary case for a profound shift from throughput to ‘roundput’, from ownership to access. The circular economy is enabled by disruptive information technology and the design of materials and products to flow in effective cycles and at high quality – ‘made to be made again’. The size of the prize is in the billions of dollars of materials cost savings per year. This volume contains contributions on understanding the model, business case studies, the performance economy, history and development and the entrepreneurial opportunities of these fluid times."

"The report 'New era. New Plan. Europe' shows us the possibilities and opportunities a fundamental shift in taxes has to offer. It is a valuable study for policy- and decision makers in businesses and governments who are looking for solutions to address the challenges of our time: climate change, pollution, inequality, unemployment and resource scarcity."
