ASP Composting Program Allows a Facility to Test Before Invest

January 29, 2020

SCS Engineers launches a new program enabling waste managers and facilities to pilot test Aerated Static Pile (ASP) composting before making a capital investment. There is a high interest in organic materials management (e.g., composting, anaerobic digestion), driven by state and local regulations for diversion of organics from disposal facilities and the desire to reduce carbon emissions.

The organic fraction of any waste stream is successfully compostable, including materials, such as food scraps, yard trimmings, food processing by-products, and biosolids. The organic fraction of the municipal waste stream, which includes food scraps, is about 30 percent by weight, so it is possible to divert a significant amount from landfilling. SCS helps waste managers evaluate their organic waste streams and whether composting is a viable solution for their circumstances. ASP composting is often the preferred method because it is fast, cost-efficient, and controls odors and emissions effectively.

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. A pilot test allows 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.

SCS’ services include the setup and operation of the mobile ASP system. The system can compost up to 50 tons of targeted material per batch. SCS provides all equipment and consulting services, along with the test reports with the process and lab data. The resulting report and data are useful information to supplement a feasibility study (e.g., the quality of the end-products for sale or community use).

Greg McCarron of SCS Engineers comments, “Virtually every town can develop and support a compost program that is locally based and directly beneficial to their community. Our mobile ASP system can provide proof of concept for our clients and the information that allows managers to make informed decisions.”

2019 Environmental Business Journal Awards Announced

January 28, 2020

SCS Engineers would like to recognize our clients and our professionals who make these environmental achievements possible. Thank you.

EBJ announced on January 23 that it is honoring SCS Engineers with multiple awards for environmental business achievements, advanced technology, and another for ASP composting project merit. The official awards ceremony takes place during EBJ’s Environmental Industry Summit XVIII in San Diego, California, in March.

 

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.

 

The Information Technology Award for SCS Remote Monitoring and Control® (SCS RMC®) software is especially gratifying. 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 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.

 

Test before you invest.

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, 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.
