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.
