Ownership<\/strong>: Natural Soil Products In 2022, Natural Soil Products (NSP) experienced significant odor issues at its open-windrow biosolids composting facility. The strong odors from the windrow operation were causing complaints from the surrounding community and heightened scrutiny from regulators. Faced with pressure to mitigate odors and environmental impacts, NSP began searching for a more controlled composting solution that could reduce odors, manage leachate, and ensure regulatory compliance. The goal was to upgrade from the basic open windrow method, which offered limited control over emissions and moisture, to a technology that could increase process control and contain odors.<\/p>\n After evaluating options, NSP engaged Sustainable Generation, LLC (SG) to help identify a proven odor-reducing composting technology. SG ADVANCED COMPOSTING\u2122 Technology \u2013 the SG BUNKER\u00ae System with GORE\u00ae Cover \u2013 was selected for a pilot test due to its track record of dramatically reducing odors (by over 90% in similar projects), meeting EPA 503 regulations for pathogen reduction and vector attraction reduction, and improving overall environmental control. This covered, aerated static pile technology was designed to address the site’s challenges, including odor mitigation, leachate management, vector control, and compliance with stringent Pennsylvania Department of Environmental Protection (DEP) regulations. With odor reduction being the most pressing issue, NSP and SG launched a pilot demonstration in 2022 to validate that this system could meet the facility’s needs and outperform the existing windrow process.<\/p>\n In 2022, NSP’s pilot demonstration project utilized a single SG MOBILE\u00ae System (a mobile version of the covered aerated static pile) with a GORE\u00ae Cover to compost biosolids on a trial basis. Within days of setup, the pilot unit was operational, composting a blend of biosolids and bulking agents under the protective cover. Multiple batches were run over the pilot period to evaluate key performance metrics, including odor mitigation, leachate and moisture control, vector (pest) control, and final compost quality. The pilot also aimed to confirm that the process could meet or exceed all local and state regulatory requirements, such as pathogen reduction standards, while determining the optimal recipe and cycle time for NSP’s materials. This side-by-side evaluation against the traditional windrow method allowed NSP and regulators to compare environmental impacts and compost results directly.<\/p>\n Pilot Demonstration Results:<\/strong> The pilot study confirmed the effectiveness of the SG-covered composting system on all objectives:<\/p>\n These outcomes of the pilot project gave NSP complete confidence in SG ADVANCED COMPOSTING\u2122 Technology. The pilot demonstrated that the SG system could outperform the windrow operation, all while mitigating odors and leachate issues. This successful demonstration proved the feasibility of scaling up the covered aerated static pile solution. Based on the pilot results, particularly the significant odor reduction, NSP proceeded with plans to implement a full-scale SG Bunker System at the facility.<\/p>\n\n\t\t
