Old Line Environmental is a biosolids and wastewater solutions provider located in Curtis Bay, Maryland serving the mid-Atlantic region. Our services include biosolids management, industrial non-hazardous residuals management, food and yard waste composting, and wet waste separation.

Old Line Environmental, Inc. is comprised of employees who have spent over 25 years in the biosolids and wastewater treatment industry. It is privately held by Lisa Williams and Steve Toft. Since the company is majority owner by Lisa Williams, Old Line Environmental is therefore a Women Owned Business Enterprise (WBE) and will be registered with the Maryland DOT MBE office.

Having spent many years throughout the U.S. working in the industry, the ownership has elected to focus on several key projects specifically in the mid-Atlantic States. With an ever-changing regulatory environment, they have elected to focus on specific projects developing innovative, sustainable, and cost-effective solutions as opposed to creating a large corporate culture. Attention to detail and customer service is a hallmark of the company. A great deal of time is spent focusing on industry problems such as Wet Well debris, “Class A” products, and developing markets for products, while at the same time performing standard management options such as land application.
