Anaerobic Digestion

Anaerobic digestion

The majority of Anaerobic Digestion (AD) plants suffer from low performance, operating at only 65% of their full potential.

AD faces multiple problems:

This leads the AD operators to spend time and money looking for innovative solutions to overcome these problems and increase plant’s efficiency as well as their revenue.

CreChar® AD Enhancer®

CreChar® is a unique patent-pending additive that brings peak performance to Anaerobic Digestion.

CreChar® is produced using a high temperature, oxygen-limited process called Pyrolysis from low value paper waste, like used paper cups and low-quality paper and cardboard waste.

CreChar® is environmentally friendly, improves soil quality and offers long-term carbon sequestration.

CreChar® addresses multiple issues in the biogas production process and ensures higher gas and digestate quality and increased production efficiency when added to the process. CreChar® comes in two grades: standard and premium. The Premium CreChar® is bespoke product tailored to the individual needs of each biogas plant to ensure the top performance.

Carbogenics offers operational service consultancy along CreChar® to provide the AD plant owners with the confidence of the highest possible plant performance.

How does CreChar® work?

CreChar is a porous carbon additive, with a unique composition of organic and mineral components

Which provides three key benefits:

Thanks to its unique properties, CreChar® can increase the stability and efficiency of the biogas production process. We tailor the necessary treatment to the requirements of individual AD plants to provide improvement in biogas yields up to 15%.
