From digestate to valuable substance

Product catalog summary
Introduction
MKR has been a leader in intelligent process media handling for over 20 years, focusing on modular solutions for ecological and economic production cycle optimization. Since 2010, the company has specialized in recycling technologies for digestate from biogas plants.

Company History
Founded by Anderl Metzger, MKR has grown into a global entity with over 45 employees. Notable achievements include the creation of the first MKR suction and filter cart, the launch of vacuum evaporators, and the ET series introduction, which cut energy consumption by 50%.

Product Development
MKR prioritizes innovation, flexibility, and well-designed system solutions. The company is ISO 9001 certified, emphasizing continuous development and practical testing to maintain high technical standards.

Consulting and Service
MKR offers expert customer support with a focus on ecological and economic factors, ensuring rapid service and spare parts supply both domestically and internationally.

Manufacturing
All core components are produced at MKR's Monheim facility, ensuring flexibility and high quality.

Evaporator Systems
MKR provides various evaporator systems, including RT400, RT600, DV1000, and DV2000, each with distinct performance features like suction volume flow, distillate capacity, and heat removal needs.

Advantages of Evaporation
Benefits include significant storage volume reduction, improved nutrient management, decreased transport needs, and efficient heat use. These systems facilitate the production of transport-capable ASL and concentrates, and declaration-capable mineral fertilizers.

Functional Schematic
The document features a schematic of fermentation-residue refining, showing the process flow from digestate to valuable products like concentrate, distillate, and ASL solution.

Conclusion
MKR's evaporator systems offer substantial environmental and economic advantages by optimizing process media recycling and minimizing waste.

Overview
The document details the DV evaporator systems used in biogas plants, focusing on the functional schematic of models DV1000 and DV2000. It describes the digestate treatment process and the production of by-products such as fibrous materials, concentrate, distillate, and ammonium sulfate solution.

Functional Schematic
The schematic illustrates material and energy flow within the biogas plant, including waste heat and electricity use, and biogas production. Key components include the MKR-evaporator and separators that process digestate into valuable products.

Products and Utilization
The document lists products from the evaporator stage, such as fibrous materials, concentrate, distillate, and ammonium sulfate solution, with typical nutrient contents and recommended uses. For instance, fibrous materials serve as humus fertilizer, while the concentrate can be stored or exported.

Practical Applications
Case studies of two biogas plants demonstrate the benefits of vacuum evaporators in reducing transportation costs and increasing nutrient concentration in fermentation products. The use of ammonium sulfate solution as a mineral fertilizer is also discussed.

Technical Information
The document concludes with contact information for MKR Metzger GmbH and notes on further product details and potential technical changes.
