Test Your Feedstocks at Simulated Full-Scale Conditions

The biological process of composting is sensitive to both the characterisitcs of feedstock and to process conditions.  The ECS Compost Process Lab provides data so facility operators can:

  • Identify optimal mix configurations,
  • Optimize airflow rates,
  • Measure actual performance characteristics over time,
  • ‘Right-size’ a system.

Compost Project Goals

Projects often have multiple goals.  ADT analysis can help inform:

  • Rate of Stabilization (CO2 Evolution and/or Solvita)
  • Anticipated Odors
  • Mass Balance
  • pH change
  • Other key process indicators

ECS helped us run several tests on our organics as a feedstock for compost systems. We received useful data in a timely manner, and avoided having to build an entire compost facility to do so! Matt Hoekstra, PhD FoodCycle Science
