LFG to RNG

April 16, 2020

Environmental Business Journal had this to say in their recently published Emerging Technology & the Environmental Industry issue:

SCS Engineers has built an impressive history, set of accomplishments and qualifications in designing, building and operating Renewable Natural Gas (RNG) facilities. In the RNG field, which is one of the company’s most important market areas, SCS creates the RNG by removing almost all other gas constituents except the methane. These other constituents include carbon dioxide, hydrogen sulfide (H2S) and other sulfur compounds, and volatile organic compounds (VOCs) including siloxanes, oxygen, nitrogen, and waste.

According to Steve Hamilton, a senior vice president, SCS’s leadership position is a result of the firm’s holistic approach and experience.

Our teams employ decades of energy systems expertise as we analyze and evaluate the effects of variations in processes and the parameters important to success. SCS models, maps, and evaluates complex systems and processes to evaluate plant performance. We account for project objectives and requirements while taking your technical, business, energy and environmental objectives into account.

SCS is receiving the Gold Business Achievement Award for a Large Environmental Firm, for outstanding business performance in 2019. We largely attribute our organic growth to our clients interested in Sustainable Materials Management (SMM) and renewable natural gas (RNG) services. Our SMM programs increase our clients’ solid waste management efficiencies, reduce waste, and support sustainable recycling, and our design and design/build facilities convert landfill gas, dairy digester gas, and wastewater treatment plant digester gas to RNG. In addition, SCS’s Geographic & Practice Area Expansion initiative in 2019 enables us to expand our professional engineering and consulting services for liquids management, wastewater treatment, and emerging contaminants from new offices in the South, Central, and Midwest regions of the United States.

SCS RMC technology helps lower landfill operating costs and maximize gas capture by integrating next-generation supervisory control and data acquisition (SCADA) opportunities such as 3D imaging from drones and virtual reality (VR). Beyond typical SCADA features, our system uses aerial data to compose topographic mapping, 2D images, and 3D renderings. SCS RMC can also incorporate geographic information systems (GIS), thermal, near-infrared, and methane leak detection data. The 3D model in use by San Bernardino County and other clients incorporates a Microsoft HoloLens VR headset that allows executives, facility management, and operators to “walk the site” from their offices, as well as view and control equipment remotely from almost any internet-connected mobile device. The technology integrates with our SCSeTools® platform, in use on over 600 landfills that help facilities continually gauge operational health and spot trends that help determine when and how to invest in infrastructure.

 

ASP Composting System
ASP Composting System diverts 40,000 tons per year of organic waste into rich compost for sale at the Miramar Landfill Greenery.

The Environmental Services Division of the city of San Diego, in collaboration with SCS Engineers, is receiving the Composting Project Merit Award in recognition for the composting operation at the Miramar Landfill in San Diego. In collaboration with the City, SCS designed an innovative covered Aerated Static Pile (ASP) composting system that will divert 100,000 tons per year of organic waste from the landfill. The ASP became operational in August 2019 and will compost 40,000 tons per year into useful by-products (and has capacity for an additional 20,000 tons). It provides an enhanced stormwater control system, and will eventually run on renewable energy generated from the landfill. According to the StopWaste.com calculator, the upgrade reduces greenhouse gas emissions by the equivalent of removing 19,015 cars from the road.

In addition, the recent announcement of SCS’s ASP Composting Pilot Program is making headlines. SCS owns a covered ASP compost system that is mobile and can be set-up on sites within an area of 50 feet by 100 feet, or less. In the covered ASP compost system, process and odor control is pro-active with a shorter composting period. Pilot tests allow waste managers to assess composting and to see if it is the right fit for their situation. The ASP system processes material batches in two months. Additional batches or “recipes” can test in 2-month intervals.

“Managing air, water, and soil pollution prevention are driving state and local regulations,” said Bob Gardner, a Senior Vice President of SCS Engineers. “Offsetting as much of the cost by improving operations, lowering energy consumption, and switching to renewable energy resources is critical to our clients.”

 

About SCS Engineers

SCS Engineers' 50th Anniversary logo featuring the number 50 and decorative elements symbolizing environmental engineering and consultingSCS, an employee-owned environmental consulting and construction firm, is celebrating our 50th year in business. We are producing technologies and programs that lower industrial operating costs and reduce greenhouse gases for private and public clients who are establishing goals to reduce their environmental impact.

Our technologies and programs are finding footholds in the agricultural, industrial, and manufacturing sectors as municipalities and companies aim to reach climate change goals without passing all of the expense to consumers. SCS clients entrust us with the management of more than 35 million metric tons of anthropogenic CO2e greenhouse gases every year. We collect and beneficially use or destroy enough to offset greenhouse gas emissions from 7.4 million passenger cars annually.

In August 2019, SCS Energy broke ground on construction of a 4,000-scfm landfill gas to renewable natural gas (RNG) plant in Indianapolis. Indy High Btu, LLC engaged SCS Energy to build the RNG plant under an engineer/procure/construct (EPC) agreement. Indy High Btu, LLC is jointly owned by Kinetrex Energy, Southside Landfill, and EDL Energy.

The RNG plant employs an iron redox scrubber for hydrogen sulfide removal, membranes for carbon dioxide removal and pressure swing adsorption for nitrogen removal. The plant is on schedule to achieve commercial operation in February 2020.

Kinetrex, as a major distributor of LNG, intends to convert the RNG into LNG. RNG from the plant will fuel trucks replacing nearly 8 million gallons of diesel a year. RNG is less expensive than diesel and significantly reduces the emission of methane and other greenhouse gases.

The Indy High Btu RNG plant is the third landfill gas-to-RNG plant designed by SCS to employ nitrogen removal, meeting pipeline specifications and maximizing gas recovery. Two other plants, including a 5,000-scfm project in Kentucky, which commenced operation in March 2018, and a 5,000-scfm project in Texas, which is currently under construction and scheduled to begin operations in November 2019, are both SCS Energy designs.

SCS Energy is a practice of SCS Engineers specializing in Biogas, Anaerobic Digestion, Renewable Natural Gas and Energy Systems for industrial and agricultural operations.
