ByoPast Pasteurization system

Pasteurisation for high viscosity, high dry matter products.

The ByoPast® solution can handle highly polluted waste streams. Due to the modular tube-in-tube heat exchanger and robust engineering of the vessels and piping, high viscosity and high dry matter will be processed with high reliability and availability.

Low availability of heat

The ByoPast® solution can reduce the heat consumption due to the recuperator up to 90%.

The process

Digestate is pumped via a heating step (tube-in-tube) to pasteurization reactors at a temperature of >70 °C. The digestate is kept inside the reactors for a minimum of one hour, where reactors are being filled, standing still and being emptied continuously in an alternating method to ensure a continuous flow. The reactors are agitated with an agitator and temperature is monitored at 3 different positions to ensure a steady temperature of >70 °C throughout the entire installation. In case of a failed batch the content of only that reactor are being reprocessed.

Our positive impact

ByoPast Pasteurization system

Cost competitive solution

The ByoPast® systems are designed for large throughputs and  continuous operation. Standard system for 10-20-30 and 60 m3/hr. Cost competitive for 20 m3/hr and up.

Small footprint

Pumps and control system and heat exchanger are mounted inside an insulated 40 ft container. With pasteurization reactors to the side requiring minimal ground space.

Robust, compact, reliable

Complete with advanced control system, compatible with overall plant control/SCADA systems and  ‘plug and play’ for quick erection, reliable operation and 24/7 monitoring.

Energy efficient system

By continuous heat consumption and heat recovery (up to 90%, depending on the viscosity) combination with other heat consumers is simple and leading to large savings.

Frequently asked questions (FAQ)

Can you combine a ByoPast® system with ABP feedstock?

The ByoPast® system can be combined with a feed bunker, conveying systems and macerators that we purchase from 3rd party vendors. We can offer a complete solution or only a pasteurization system.
