Sustec – Organic Material Hydrolysis

Part of DMT Group

About the Company:

Sustec was established in 2008 by Lex van Dijk. They are a Dutch technology and solutions provider with a strong focus on sludge treatment and resource recovery, with their head office located in Wageningen, the Netherlands.

Sustec realizes technologies for sustainable solutions in the field of handling waste streams. It involves energy production, the recovery of raw materials and nutrients and the purification of water. The projects they work on are the execution and completion of TurboTec® installations (licenses, limited scope and full scope), the development and support for resource recovery NutriTec® projects, and to support start-up and commissioning of new and existing WWTP.

Sustec provides sustainable technologies for a circular economy. With a focus on sludge treatment and resource recovery, Sustec offers their customers consultancy services, laboratory and pilot testing, licensing, design and engineering, contracting and operational support.

With a strong focus on R&D Sustec is continuously investigating new possibilities for the next generation TurboTec® and Nutritec® installations. In combination with entrepreneurship, professionalism and integrity, Sustec offers their customers a wide range of solutions resulting in reliable and excellent projects/services.

About the Solution:

The TurboTec® hydrolysis organic material in a reactor by treating this material at high temperature and pressure. The TurboTec® is a continuous version of thermal hydrolysis (cTHP) and recovers its heat via heat exchangers and mixing/separation of the incoming and hydrolysed material.

The patented continuous Turbotec® process treats organic material (biomass) at a standard pressure of 4-6 bar and a temperature of 140-160°C, but higher temperatures (up to 180°C) can also be achieved. This temperature treatment also ensures hygienisation of the final biomass cake (Class A). Pre-concentrating of the biomass at just 10-12% TS, minimizes the use of costly chemicals, while belt dewatering is sufficient. The steam consumption for heating is limited to less than 800 kg/tTS, due to the efficient heat recovery via heat-exchangers and the mixing/separation step.

Biomass hydrolysis of waste activated sludge (WAS) results in up to 35% more biogas in the digestion, while in the improved final dewatering more than 30% TS can be achieved. By using cTHP the capacity of the digesters is increased, by shortening the HRT and increasing the concentrations. The Turbotec® process has lower investment and operational costs as compared to batch processes.

Solution Strengths, Weaknesses and Critical Indicators

Anaerobic Digester Associated Technology:

NOTE: There are several technology types that are used as part of an integrated manure management system that includes an anaerobic digester and are not applicable to manure management in other cases. The impact of these technologies on the critical indicators are represented as those of an entire anaerobic digester system.


  • Long usable life and can be run reliably
  • Creates energy and generates environmental credits
  • Requires proper preparation of the feedstock
  • Requires other technologies for energy utilization
  • Requires other technologies for digestate handling
  • Proper feeding & system monitoring is required to avoid system downtime
  • Proven technology for odor control, GHG reduction and pathogen reduction

Newtrient Comments/Opinions:

Anaerobic Digester technology:

  • Is proven technology for odor, GHG and pathogen reduction and energy production
  • Has a long usable life and can be run reliably
  • Require proper preparation of the feedstock
  • Usually requires other technologies for energy utilization
  • Usually requires other technologies for digestate handling
  • Proper feeding & system monitoring is required to avoid system downtime
Sustec has not been evaluated using Newtrient's 9-point scoring process because, although their process appears to be suited for use on dairy manure, Newtrient is not aware of any current dairy based projects in North America. Newtrient will continue to work with Sustec to refine the cost and performance information as it comes in with new commercial dairy installations.
