SCS Engineers Launches ASP Composting Pilot Program

SCS Engineers Launches ASP Composting Pilot Program

SCS’ covered ASP compost system is mobile and can be set up on sites within an area of 50 feet by 100 feet or less.

SCS Engineers announced a new program enabling waste managers and facilities to pilot test aerated static pile (ASP) composting before making a capital investment. According to SCS, 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 byproducts 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 noted it 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 proactive 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 two-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), according to SCS.

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