Aries Linden Biosolids Gasification Plant—Linden, NJ

Spring to Winter 2020

Riggs Distler is currently providing turnkey heavy civil, mechanical, and electrical services in support of an Aries Clean Energy project to construct a biosolids gasification plant at an existing sludge processing plant in New Jersey. This plant will be serving the largest metropolitan area in the US – The New York metropolitan area – and it will divert 130,000 tons of biosolids from landfills annually. It will be the lowest cost option for biosolids disposal in NY/NJ Metropolitan area. Read more about the project here.

                                          Challenges Overcome

                                          Riggs Distler’s work on this project is being performed inside a repurposed facility, and careful coordination of heavy civil, mechanical, and electrical work is key to keeping the project’s schedule and budget on track. As engineering work for the plant is not yet complete, portions of the work to be completed remain unknown, and these will necessitate adjustments to the project’s scope, priorities, and sequencing. Riggs Distler is relying on the expertise of our industry-leading Project Managers to stay in constant communication with the various project teams, subcontractors, and the client to ensure all work is planned and executed carefully, efficiently, and safely. 

                                          The project is located in a strong-union environment and in territory unfamiliar to the client, and Riggs Distler’s management expertise is ensuring that each step of the project proceeds with minimal disruption. Since it is critical that the client complete the project and begin generating revenues as soon as possible, our ability to get the project moving is proving invaluable to the client.

                                          Results Delivered

                                          The Aries Linden Biosolids Gasification Facility will process 430 tons of biosolids per day while producing 22 tons of biochar that will be beneficially used as a replacement for Fly ash in the production of concrete. 

                                          Aries Clean Energy CEO Greg Bafalis: “The Linden facility will be the most advanced biosolids processing facility in the world utilizing our patented fluidized bed technology. By using our environmentally friendly, renewable system, we will convert biosolids into completely renewable, beneficial products. I anticipate that Linden will receive visitors from all over the world to see this facility and how it innovatively takes a waste product and converts it into renewable energy and biochar. We are looking forward to investing in the local community and serving the region with sustainable biosolids solutions that will contribute to a cleaner, greener, healthier planet.”
