The National Lubricating Grease Institute, a not-for-profit trade organization, contributes to the growth of the grease industry by supporting the development of better lubricating greases and the improvement of grease lubrication engineering. Its activities include technical meetings, grease product certifications, educational courses, publications and professional certifications. The European Lubricating Grease Institute has a similar role and activities centered in Europe. Many members of each organization are grease manufactures and marketers, raw material and equipment suppliers, and end users.
Working groups are one of the ways that both organizations promote understanding of technologies and facilitate exchange of information about grease. Each working group consists of professionals from member companies who collaborate on projects that interest the industry. The groups meet at NLGI and/or ELGI meetings to plan and carry out projects at member laboratories. These projects are at the leading edge of developments of broad commercial interest.
