Reduce Energy

An NSF Industry / University Cooperative Research Center (I/UCRC)

The Center for Resource Recovery and Recycling (CR3) is committed to being the premier cooperative research center focused on sustainable stewardship of the earth’s resources.

Our focus is on helping industry address a pivotal societal need – the need to create a sustainable future. At CR3 you will advance technologies that recover, recycle and reuse materials throughout the manufacturing process. These advancements will help your business reduce energy costs and increase profitability, while protecting our natural resources.



Lithium-ion batteries are found everywhere. They are in our cell phones, laptops; even in hybrid cars. And with this growth in popularity comes the need to find a responsible way to recycle them.  This is where researchers at CR3 come in.  WPI mechanical engineering professor Yan Wang and one of his CR3 researchers have invented technology that takes spent batteries and identifies what is in the battery that can be reused and what impurities need to be screened out.  To learn more about this breakthrough technology that was first developed in CR3’s lab watch the video

The International Slag Valorisation Symposium

Today in its 8th edition, the “Slag Valorisation Symposium”, organized by the Materials Engineering Department at KU Leuven and held in Belgium since 2009 as a biennial conference, serves as a forum for discussions on the valorisation of slags and other high-temperature metallurgical residues. The symposium has historically brought together different expertise from academia and industry, providing a knowledge platform to share and discuss the upcoming challenges and opportunities in the world of slag valorisation and sustainable high-temperature processes. After a virtual edition in 2021, we are happy to invite and welcome again high-level speakers from globally recognised organisations. The symposium aims to cover several topics, from the scientific and technical relevance of slag valorisation to its environmental and economic impacts. The quality of the scientific committee, selected among the most recognised experts in this field, will ensure the highest standards of the accepted works.

The objectives

The objective of this 8th edition of the International Slag Symposium – Tackling future critical challenges – is to discuss and share the most updated findings in the field of slag and metallurgical residue valorisation, metals recovery, slag’s life cycle analysis, policy for slag valorisation guided by climate neutrality and resource efficiency principles. All researchers are invited to share their enthusiasm by submitting their works on the following topics:

  • Fundamental studies on liquid and solid slags
  • Hot-stage slag engineering, slag solidification, slag conditioning, internal reuse
  • Slag cleaning and metal recovery
  • Production, properties and performance of slag-based products
  • Process development for sustainable technologies
  • Industrial case studies on slag/residue valorisation
  • Environmental and economic analysis
  • Policy and regulations

The contributions submitted by the participants, together with the lectures from the invited speakers, will enhance discussions and new ideas towards a more sustainable future.  For more information, see
