LEGALLY COMPLIANT PROCESSING OF BIOWASTE. POST-TREAT YOUR SIEVE RESIDUES ECONOMICALLY.

Future-proof solutions with Doppstadt’s mobile modular processing concept MMAK - an investment that pays off.

Biowaste and Sieve Residues processing

Presented here, the successful implementation of the MMAK (Mobile Modular Processing Concept) according to the legal and market-specific framework conditions in Germany. Together with our expert local dealers, we individually adapt the MMAK to the country-specific framework conditions and your needs.

The latest amendments to the Biowaste Ordinance (BioAbfV) pose a major challenge for the processing of biowaste. To reduce the discharge of plastics, glass and metals into the environment, the requirements for the removal of foreign substances have been tightened considerably.

Using a mobile modular treatment concept that is individually tailored to your operation, you can efficiently pre-treat fresh biowaste in a legally compliant manner andeconomically post-treat sieve residues.

THE FUTURE IS MOBILE-MODULAR.

Our experts have smartly combined robust Doppstadt machines and proven add-ons to create a mobile modular system. All of the machines can be used flexibly in different fractions. You can react quickly to changing conditions by recombining the components of the system. It means you are ideally set up for the economical and legally compliant processing of your biowaste – no matter what challenges await you in the future.

BENEFIT FROM OUR IDEAS.

By mobile modular processing concepts, we mean combining mobile Doppstadt machines in a modular principle. Intelligently combined, they can be used in many applications.

THE PROCESS STEPS OF BIOWASTE PRE-TREATMENT AND OF THE SIEVE RESIDUE POST-TREATMENT.

STEPS 1 - 3: EFFICIENTLY REMOVE CONTAMINANTS FROM YOUR BIOWASTE.
Thanks to Doppstadt’s mobile modular processing concept, you are on the safe side. It enables you to pre-treat all biowaste in a legally compliant and economical manner. In addition, the machines are so flexible that your operation can react promptly if the framework conditions change.

STEPS 1 - 4: EFFICIENT PROCESSING OF SIEVE RESIDUES TO REDUCE DISPOSAL COSTS.
The post-treatment of sieve residues is carried out using the same mobile modular process concept as the pre-treatment of biowaste. After two separation stages, you get an almost completely contaminant-free medium and fine fraction, from which you can sieve high-quality finished compost. The concept can be adapted flexibly if the influencing factors change.

The METHOR opens bags, breaks up material composites, crushes stones, concrete and wood parts and separates Fe metals. It then conveys the material evenly onto the first SELECTOR 400 spiral shaft separator.

The SELECTOR 400 spiral shaft separator separates all impurities larger than 250 mm. They are discharged as overflow onto a mobile conveyor and stockpiled. A windsifter is installed above the spiral shaft deck, which extracts foils and other 2D impurities and conveys them into a settled roll-off container. The underflow is conveyed to the second SELECTOR 400.

The second SELECTOR 400 spiral shaft separator further separates the material stream so that the second windsifter can extract the remaining foils and 2D impurities. After that, the medium and fine fractions are almost free of impurities.
You can now feed both fractions into the first biogenic treatment stage (composting or fermentation).

The underflow and overflow are conveyed into a drum screen machine and the last impurities are removed. The fractions produced can be fed directly into the finished compost.
