Our Preliminary Design Process

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

Our Unique Approach

ECS offers our unique set of tools and skills to help both new and existing compost facility operators efficiently navigate an increasingly complicated terrain. As facility designers we are heavily involved in all aspects of planning, permitting, and designing. As technology and equipment providers we are immersed in the details of facility construction and start-up. In our technical support role we are the first call for most of our clients when any sort of process related issues arise. ECS engineers and scientists are constantly working with our loyal clients to help them measure and optimize their processes in response to changes in regulations, working environment and opportunities.

ECS approaches all our client’s challenges and opportunities with an open mind and a data-driven approach. Our “open mind” comes from working with clients who are succeeding with a wide range of composting methods. This has given rise to the ECS “Tool Kit” of process technologies which we configure to meet the unique needs of each facility. We use real process data to test performance claims, whether they are ours and by others. For years we have gathered data through our comprehensive compost control and monitoring systems, through our client support work, and from our own research. We use this data and rigorous first-principles modelling to predict process and economic performance.

Our Consulting Process

We typically begin with an efficient high-level economic and technical assessment of the issues and opportunities presented. This assessment provides the client with the information to further specify and/or reduce the number of options. From there we go only to the technical depth necessary to answer the key questions:

• What is the business case?

• What are the risks?

• What are the best process options?
