Meet SCS Engineers professionals Christine Collier, Tom Shuput, Mike Miller, Eric Nelson, and Rebecca Nelson at the 2018 Iowa Recycling and Solid Waste Management Conference and Trade Show, October 8-10 at the Mid-America Center in Council Bluffs, Iowa! Registration for this event is open. We hope to visit with you at SCS’s booth 104. A few event highlights!
Tuesday, October 9
Wellfield Data Management at a Glance (.5 CEUs) with Ken Brynda. Room F at 1:50 pm.
This presentation is designed to encourage those in attendance to utilize their wellfield data for better overall wellfield management beyond compliance. The results should include overall improved LFG collection, which will help minimize nuisance odors, reduce the risk of lateral LFG migration from the refuse and potentially provide more LFG to beneficial end-use energy recovery projects.
The presentation will highlight key information that can be gleaned from a set of wellfield data and focus on using geospatial mapping as the preferred method of analyzing wellfield data versus the traditional spreadsheet.
Rising to the Challenge: How Dane County Leads C&D Recycling in Wisconsin (1 CEU) with Betsy Powers and Wendy Larson. Rooms K&L at 4:00.
The Dane County Department of Public Works (DCPW) Rodefeld Landfill has low tipping fees and little room for expansion. The county sees promise in diverting construction and demolition (C&D) materials from the landfill by recycling them, but cheap landfill space, a low concentration of C&D materials, and only a mid-sized market for recycled materials make it hard for recycling to thrive in Dane County. Learn how a new partnership of private and municipal organizations helped the county successfully compete against its own landfill to become a leader in Wisconsin C&D recycling.

Enhancing Recycling Through Market Development and Product Stewardship (.75 CEUs) with Michelle Leonard and John Foster. Rooms A&B at 8:30.
Recycling markets are struggling as China imposes trade barriers, and the responses have been to cease accepting certain materials or stockpile materials until the markets rebound. This market shift has put a burden on managers to identify opportunities to increase participation in recycling while maintaining financially viable programs. Development of local markets is necessary and will take time. Policies that encourage local market development, including product stewardship and extended producer responsibility, have proven successful in stimulating the recycling of certain materials. This presentation will provide examples of successful market development activities, and tools for municipal managers to utilize to identify appropriate, relevant programs for their solid waste systems.
Organics Boot Camp (3 CEUs) includes these sessions:
Waste Characterization Study Benefits Community Programming with Jane Wilch. Examination of how the 2017 Waste Characterization Study results are helping to shape programming through better understanding the waste streams at the Iowa City Landfill.
Food Waste Minimization for Iowa Schools: K-12 with John Bruce. The Iowa Waste Exchange, along with the Iowa Department of Natural Resources and the Department of Education, conducted waste audits at participating Iowa schools to quantify their lunch waste. The data was used to develop school-specific action plans to address waste minimization, as well as to build a waste minimization toolkit that is available to all Iowa schools.
Composting Operations from an Operator’s Viewpoint with William Conrad. The presentation will cover the mechanisms of composting, the best ways to manage it on a commercial scale and the relevance it has in today’s environment.
Organics Processing Facilities – Making More Sense than Ever with Leslie Lukacs. With interest at an all-time high about organics processing, now is a good time to review the latest in successful techniques and systems.
This presentation will first summarize the principles of aerobic and anaerobic systems and requirements for: feedstock, key design criteria, operating storage, footprint, buffer, and overall land requirements, net outputs in energy and product, capital and operating costs and overall advantages and disadvantages. For anaerobic systems, energy production rates will be presented.
Secondly, we will present operating best practices for protecting the environment and minimizing nuisance to the public. This would include best operating practices for controls on process emissions, fugitive dust, odor, leachate, spills, biogas leaks, and residuals. Permitting issues will be covered and what aspects regulators typically look at more closely than others. Also, the role and importance of preliminary planning and design studies including technical and economic assessments will be discussed.
Finally, some successful private, public-private partnerships and municipal facilities will be presented. Attendees will come away with an understanding of the following:
- Working knowledge of the advantages and drawbacks of aerobic and anaerobic systems.
- Basic design and operating parameters and costs.
- Potential issues of permitting, environmental and public impact.
- Expectations of preliminary technical and economic assessments.
Modeling the Impacts of Organic Waste Diversion on LFG Recovery from Landfills with Eric Sonsthagen. This presentation will address the theme of confronting climate change directly by evaluating the effectiveness of different strategies for reducing greenhouse gas (GHG) emissions from the waste sector. Because landfill methane emissions are the largest GHG emission source in the waste sector, the speaker will use landfill gas (LFG) modeling to evaluate the potential effects of different rates of organic waste diversion on landfill methane emissions.
This event is hosted jointly by the Iowa Recycling Association and Iowa Society of Solid Waste Operations.
