We are passionate compost experts, engineers and scientists

We are relentless in our development of new products and services tailored to meet the needs of our industry and fill the technological void that we frequently encounter.


Tim O’Neill founded Engineered Compost Systems in 1999 to develop and manufacture technology and to provide technical services for large-scale composting facilities.  Tim started in business in 1986 by co-founding Measurement Technology NW with Peter Zieve and working as Peter’s first Vice President of ElectroImpact during its founding years.

In the 1990’s, Tim was co-owner and lead mechanical and controls engineer at Green Mountain with the focus of developing small in-vessel systems.  Since 1999, ECS product and service offerings have expanded in our quest to respond to market needs.  As the name implies, Engineered Compost Systems uses top quality engineering to meet these demands.  To this end, ECS has had the opportunity to build the most qualified group of compost engineers in the industry.

Sister companies of ECS include Thermetrics, which manufactures a wide range of precision instruments for measuring and evaluating the thermal comfort of textiles, garments, protective apparel, and dynamic thermal environments such as automobile, truck, and aircraft interiors. Rugged Controls, another sister company, previously named LCI, designs and manufactures durable, multi-channel winch line control, wireline monitoring, and tensiometer instrumentation used in demanding commercial and oceanographic applications ranging from polar to tropical.

Join our Team

Our projects make the world a better place. ​ ​With each facility we divert nutrient rich food waste, yard waste, and biosolids away from landfills and into beneficial re-use streams. We are able to dramatically reduce odor from aged infrastructure and make the area around the composting facility more pleasant to live. ECS is a small company with a collaborative team, which give employees the opportunity to have a meaningful impact.

Compost Scientist responsibilities will include the following:

  1. Compost Research
    • Stay current on published compost science and forge relationships with other compost researchers.
    • Lead both in-house and paid compost research efforts in the fields of compost process optimization and measurement and control of compost air emissions.
  2. Compost Process Consulting:
    • Travel to client facilities to conduct audits that include assembling and analyzing a broad range of process data. Use this data to develop strategies to best meet client goals.
    • Oversee the operation a ECS pilot systems aimed at developing design and operational specification to best meet client goals.
  3. Technical Support of Facility Permitting
    • Support client permitting consultants in the effort to negotiate reasonable, science-based permits that seek to combine both better optimized process and reduced environmental impacts.
  4. Supervise ECS Compost Process Laboratory
    • Oversee and carry out testing in the ECS laboratory to characterize the degradability of, and optimize process design for, specific feedstocks.
    • Oversee and carry out air emissions sampling, arrange outside laboratory analysis, and use the results to model full-scale emissions of both regulated gasses (VOCs) and odors.

    • Present technical papers at conferences
    • Write technical articles for industry and scholarly publications
    • Write ECS whitepapers
    • Contribute technical content to ECS newsletters.
