J.P. Mascaro & Sons is dedicated to a greener future.  We operate several of the largest and most cutting-edge indoor composting facilities in the country. We compost biosolids (sludge) from municipal wastewater treatment plants and produce a rich, organic compost suitable for a wide variety of landscaping and soil enhancement applications. Unlike our competitors, all composting is performed inside state-of-the-art buildings equipped with environmental control systems.  These structures include leachate management and biological odor control systems.  This process enables composting to be accomplished in a manner that minimizes any effect on our environment.
