Waste Connections - Silver Springs // Rainier, WA



    Client Needs:


    Silver Springs Organics was purchased and redeveloped in 2011 by Waste Connections to handle the growing yard and food waste streams from their collection areas in the south Puget Sound region.  They put a high premium on product quality, odor control and efficiency.  During this transition they were also required to capture and reuse all contact water.



    ECS Solution:


    ECS supplied design and the aerated composting technology to previous owner of SSO starting in 2007.  In 2011, ECS provided process analysis and was part of the design team that led to new facility that was constructed in 2012.  This facility features a roof to minimize contact water, an aerated tip floor, primary composting in an Aerated Turned Pile (ATP) with reversing aeration, and secondary composting a fabric covered negatively Aerated Static Pile.  Process air from negative aeration is scrubbed in biofilters.

    "ECS has been a trusted partner in our business since conception nearly 15 years ago. Their ability to create customer centric solutions and custom, site specific design resulting in flawless execution has made them invaluable to us. From our initial build of a 120k tpy ASP system, our later conversion to a 5 acre indoor hybrid system and all the challenges along the way, ECS has always delivered (and continues to) sound, dependable and predictable results with impeccable customer service. We have also had great success using their expertise for complex consulting and regulatory interface. I cannot imagine the difficulties we would have had over the years without them on our team. ECS is a great company made up of great people who have world class knowledge and technology for compost facilities that are looking to advance the industry and raise the bar.
