CreChar® benefits for your AD plant

Key benefits of integrating CreChar into your anaerobic digestion systems:

Enhanced Biomethane Production by up to 10%

Biochar provides a favourable habitat for beneficial microorganisms, resulting in increased biogas yields and improved methane.

Enhance Quality of Biogas

Increased methane content by up to 3%.

Trace Elements

Improved microbial efficiency can lead to reduced requirements for trace element additions.

Reduced Process Instability

Biochar helps to reduce fluctuations and maintain stable process conditions, reduces ammonia and H2S.

Case studies

Backed by scientific and commercial expertise, we develop sustainable biochars for a range of industrial applications.

CreChar Case Study – Site E

Site E is a CHP site which operates a Marches Biogas Double Ring digester on a mix of feedstocks, including Potato Peelings, Potatoes, Vegetable Waste, Chicken Manure, and Liquid Sugar.

CreChar Case Study – Site D

Site D is a farm-based AD plant using predominantly farm and distillery wastes as well as some energy crop.

CreChar Case Study – Site C

Site C is a farm-based AD plant using energy crops, chicken manure, whole sugar beet on a seasonal basis and pot ale.

CreChar Case Study – Site B

Site B is a farm-based AD plant using ensiled maize, cattle manure and sugar beet pulp on a seasonal basis. The site has 2 primary tanks in parallel with a total volume of 9600m3. It is a 5MWth biomethane plant with a gas to grid cap of 500m3/hr.

CreChar Case Study – Site A

Site A is a farm-based AD plant using predominantly farm and distillery wastes as well as some energy crop. The site has 2 tanks in series with a total volume of 7000 m3 and generates 1.1MWe via 2 CHP engines.

CreChar Case Study – Site F

Site F operates a 4500m3 two stage semi-plug flow digester with a 1500m3 primary and 3000m3 secondary. The customer processes biogas via CHP engines into electricity with a capacity of 2 MW across 2 locations.

CreChar® FAQs

Find clear answers to common questions about CreChar®, its benefits, and how it works.

What type of feedstocks does CreChar® work with?

CreChar® is effective across a wide range of feedstocks, including agricultural residues, food waste, distillery waste, and manure. However, performance is driven less by the specific feedstock and more by the operational challenges within your plant. 

CreChar® delivers the greatest benefit in systems with variable feedstock mixes, frequent feedstock changes, or issues such as high H₂S or ammonia levels.

CreChar® is compatible with all common anaerobic digestion systems, including continuous stirred-tank reactors (CSTR), plug-flow digesters, and covered lagoons, across both mesophilic and thermophilic processes.

Supplied in biodegradable paper bags, it can typically be added directly via the feed hopper. For alternative feeding systems, CreChar® can still be used, although minor adjustments to the dosing method may be required.

This is exactly where CreChar® performs at its best. It is specifically designed to support process stability during periods of change, helping to buffer fluctuations in feedstock composition and operating conditions, and maintaining consistent digester performance.
