Our Systems

Previously known as STM Ecosystems, Sorbent Dynamics Dry Sorbent Injection (DSI) systems are air pollution control technologies used to reduce the emissions of acid gases, mainly HCl and SO2, as well as other pollutants from industrial combustion processes.

Dry sorbent injection is an effective and relatively cost-efficient method for controlling acid gas emissions compared to other technologies, like wet and semi-dry scrubbers and circulating fluid bed scrubbers.

End-to-end Solutions

Build a simply functioning system using our proprietary technologies and components that are easy to use and maintenance-friendly. These are systems that simply work, without having to use costly accessories or complicated control systems.

Fully Customizable

Each system equipment element can be supplied in different cofigurations, and arranged to match the particular application.


Our equipment is simply designed to have zero periodic maintenance, with easy change elements at end of life.


We implement only the latest technical designs and technology for all Sorbent Dynamics machinery components.


Our technology can be adapted to different functions and processes due to its modular construction by simple tool changeout.

Get What You Need, When You Need It

The simplicity of our systems is based on the simplicity of our equipment, which means that our delivery times are never going to be the bottle neck in your execution schedule.

Trust Our Equipment

Reliability is the hallmark of our system components. From feeders to mills to injectors, up time is one of the most prized features of our equipment.


Our equipment is manufactured with great care by expert craftsmen with years of experience, resulting in high quality components and long-lasting machines.

High Quality

All third-party components are the highest quality available on the open market. Our oversized, high quality German gearmotors allow our systems to survive under the harshest conditions.

Make Your Next Project Quick and Easy

6 Simple Steps to a Successful DSI System:

Step 1: Specify Your Process

If necessary, we will work with you to define the pollution abatement process and determine which sorbent solution is best for your process.

Step 2: Analyze Your Problem

The next step is to help you determine which system or component is best suited to achieving your process solution.

Step 3: Build Your Equipment

We will then design and build your system according to your demanding quality requirements and specifications.

Step 4: Integrate Into Your Process

We will assist you with the integration process to ensure that your plant is working in the most effective and synergistic way possible.

Step 5: Assist With Installation

Our expert installation and erection supervision will help you to reduce on-site cost by helping you find the most effective methods of installation.

Step 6: Comissioning and Training

Our commissioning engineers will assist you with initial operation and training on operation and maintenance functions.
