CR. micronutrient mixtures for fermentation biology

For a wide variety of systems

• Municipal waste fermentation plants
• Sewage treatment plants with co-fermentation
• Anaerobic industrial sewage treatment plants /li>
• Dry fermentation plants
• Percolate plant systems
• External biological desulphurisation projects

For different types of co-substrate

• Waste materials and waste water from food production
• Activation of methanogenic organisms in the fermenter
• Waste materials from carcass utilisation plants and poultry production
• Slurry from ethanol production
• Waste materials from starch production and fat separators

What is special about CR.CON^® and CR.COMPACT

The CR.-mixtures compensate for deficiency, unfavourable conditions and low availability of micronutrients.

The mixtures are factory-specific, formulated and produced on the basis of ac-curate iCAP spectrometric analyses and in accordance with scientifically established requirement values.


CR. micro-nutrient mixtures complement the mineral and trace mineral content in the plant

How CR.CON^® products work

• Stabilisation of breakdown processes
• Activation of methanogenic organisms in the fermenter
• Synchronisation of the different stages of biogas production
• Sustained increase in fermenter efficiency
• Maximum methane yields
• Increased Company Profit

VOA/TAC values and energy yield with use of a CR. mixture

For every application:

The tailor-made CR.CON^® products can be used in plants of any output capacity.

Depending on the circumstances of the biogas plant, the CR.CON^® micronutrient mixtures can be supplemented with other specific active agents.

With stable fermenter output:

The CR.COMPACT line is characterised by low dosage and an excellent price-output ratio.

The more highly concentrated CR. COMPACT products are used after the plant has been set for a stable, optimal output level. Compatibility with active substances is limited.

Use of the CR.CON^® product line

• Analysis-based, individual mixtures
• Suitable for any organic capacity size
• Unlimited compatibility with active substances
• In all types of biogas plant
• Use rate: 3; 4; 5 kg/100 kW

CR.CON^® and specific combinations of active substances

CR.CON^® START - Developed for the start-up phase. The mixture of micronutrients, iron compounds and buffer substances creates an optimal environment for the process biology and effectively reduces the concentration of hydrogen sulphide in the biogas.

Ncon – reduces the inhibitory action in nitrogen-rich facilities, especially in plants using large amounts of protein-rich substrates.

Scon – binds the hydrogen sulphide in the substrate.

SLcon – promotes the disintegration of settled biomass at the bottom and floating biomass at the top and prevents biomass layers from reforming.

VIScon – Homogenises the fermentation substrate and reduces wear and tear of pumps and stirrers.

SPcon – Reduces and prevents foam formation by altering specific physical characteristics of the substrate.

PHcon – Supplements buffer substances, thereby increasing buffering capacity and preventing fluctuations in the process operation.

ThioB – optimises the biological desulphurisation of biogas in external solid bed systems.

Tailor-made CR.CON^® products

The situation in a fermenter differs widely between biogas plants, depending on the substrates used, operational management and a multitude of other factors. The CR.CON^® line enables the integration of any complex of active substances for any biogas plant.

Use of the CR.COMPACT product line

• Analysis-based, individual mixture
• Limited compatibility with active substances
• Suitable for any capacity size
• Supplied in fermentable bags
• Dosing of sealed bags
• Use rate: approx. 2 kg/100 kW and day
