About Us

Surplus Property Roundtable (SPR) is a not for profit, tax exempt corporation* organized to provide educational opportunities and resources to promote the responsible ownership, management, remediation, re-purposing, and disposition of real estate with legacy environmental issues. The goal is to re-establish the properties’ productive use in cooperation with all stakeholders. Our Benchmarking Function and three standing committees allow for deeper exploration of relevant topics and the sharing of best practices, providing significant value to member companies:

SPR started in 2012 when four companies founded the Surplus Property Roundtable. The original founders were Arconic Inc. (formerly Alcoa Inc.), BASF, ExxonMobil and Ford. SPR has steadily grown from four companies in 2012 to over 25 presently. SPR plans to maintain membership at this general level to ensure that the original concept of the small roundtable remains intact.
