Technical Services

Engineered Compost Systems is the only engineering firm in North America with multiple in-house full-time compost engineers and scientists.  Together, ECS staff have close to 100 years of professional compost engineering & organic waste management experience.  Collectively, we have assisted clients in answering questions and solving problems at hundreds of compost facilities worldwide. 

We offer a unique suite of Technical Services to help developers and operators make smart choices in development or expansion of compost facilities.  All Services produce defensible data upon which succinct interpretations and recommendations can be made, where the goal is to cost-effectively compost and recycle organic waste into high value compost end-products.




Engineered Compost Systems has provided independent compost consulting services to over 80 clients. We are intimately familiar with the challenges in obtaining compost use permits from multiple government agencies across the United States, Canada, and select international countries. We provide a quantitative and independent approach, which produces a measure of assurance required by most regulating agencies. If you are ready to build or expand a composting facility, we can help you navigate through the iterative planning stages of this challenging business venture. These steps include:

  • Analyzing the Suitable Site(s)

  • Navigating Complex Regulatory Requirements with Multiple Permitting Bodies

  • Selecting a Design & Technology Suitable to the Site and Production Goals 

  • Developing Mix Recipes and Mass Balance Models with your Feedstock

  • Engineering a Preliminary Layout for Permitting or Financing

  • Engineering a Detailed Design for Construction

 The main objective in an Engineered Compost Systems feasibility analysis is to give our best answer to the question, “will this facility be viable, economically and socially?” If anything at the planning and design stage becomes a critical uncertainty, ECS has a suite of tools to analyze the issue and produce quantitative results upon which decisions regarding the viability of facility can be made. 

The following topics are frequently analyzed with our feasibility studies:

  • Quantifying Food Waste Diversion 

  • Forecasting Operational Expenditure, Capital Expenditure, and Revenue (pro forma)

  • Researching Compost Marketability, Supply/Demand, and Sales Prices

  • Researching Bulking Agent Availability, Cost, and Suitability

  • Measuring Emissions & Odor (more on this below)

  • Modeling Contaminate Removal Scenarios

The operational requirements of a composting facility are ever evolving.  New regulations, nearer neighbors, and increasing and/or changing feedstocks can and will force evolution over time, regardless of system provider. Even without these external forcing functions, almost all facilities can improve their processes and bottom lines with expert input from a fresh set of eyes.

Engineered Compost Systems offers the expertise to improve your process.  We view facilities through the lenses of Best Management Practices (BMPs) and economic efficiency.  We guide or manage the collection of feedstock, process, and emissions data to assess compliance with BMP guidelines.  From this we can provide you with a menu of process improvements to achieve measurable differences in throughput, odor/volatile organic compound emissions, and product quality.  In addition to helping your facility achieve better BMP compliance, we simultaneously apply our extensive operational experience to help you lower costs and improve revenue.

Engineered Compost Systems conducts numerous Research and Development projects each year. Some projects are funded by clients with novel questions or intriguing business opportunities. Other projects are taken on by ECS on its own to address knowledge gaps or develop new technology, sensors, or aeration floors. ECS believes in making decisions based on empirical data, and will always pursue empirical data when given the opportunity. 

Recent Research and Development projects include:

  • Steam Heated Apple Maggot Destruction Vessel

  • Benchmark Odor Production per ton of Feedstock as Affected by Aeration Supply Rate

  • Micro Vessel for Boutique Compost Blends

Odors, volatile organic compounds (VOCs), and ammonia are air emissions that require in-depth technical understanding and expert design in order to minimize their impacts and comply with regulations.   Engineered Compost Systems has a unique set of scientific skills, actual air emissions data, and sampling and analysis tools to allow operators to comprehensively manage these emissions.  Our systems have been recognized for their superior odor control. We quantify facility emissions by conducting emission sampling at the facility's current process, or from a pilot facility.  If your facility is only in the planning phase, we have an extensive database to provide a most likely range of emissions.

Pilot facilities are a great tool that Engineered Compost Systems use to gain first-hand knowledge on the response of actual feedstock to ECS’s compost technology.  A variety of technology and process options can be tested with an ECS pilot including: pile formation (discrete or extended bed), air supply rate, air direction (positive, negative, reversing), mix recipe, moisture, static or turned, and retention time.  The pilot facility is built at a scale large enough to ensure accurate comparisons with a full facility, but at a dramatically reduced cost.  Built with flexibility in mind, the pilot can be reconfigured multiple ways until the best balance of performance and cost is achieved. 

Uses of ECS pilot systems include: 

  • Proof of Concept

  • Air Emission Quantification & Minimization

  • Product Optimization

  • Throughput & Cost Analysis
