We are Proud to be Part of Our Community
The JIMAX Group of Illinois upholds service to their community as a key pillar of their operations and is dedicated to the resiliency of their neighborhoods and company ethos, providing a wide range of volunteer opportunities that align with their core competencies.
The Tireless Project was initiated in 2015 with a stated objective of engaging the community to reduce persistent illegal dumping of tires and provide a no-cost environmentally conscious outlet for their disposal. JIMAX has worked diligently to improve the process, engage new stakeholders and partners, and increase outreach in the community, collecting more than 20,000 tires since inception. JIMAX donates equipment and a location for the project, as well as provides necessary planning and support, in addition to company employees donating their time. JIMAX could not hope to achieve the success of this program without the “tireless” assistance of employees and other local volunteers who graciously donate their time.
