New construction of a modular bio-reforming plant for papperts GmbH

As part of the construction of the new production facility for *papperts GmbH*, Goffin Energie planned and implemented an innovative, multi-stage bio-reforming plant for the energetic use of bakery waste. The plant generates at least 1.7 million kWh of electrical and thermal energy annually from previously unused stale baked goods and process residues – in line with the principles of a sustainable circular economy.

The decision was made to implement a multi-stage MBRA technology, which is optimally suited to the heterogeneous substrates used due to its flexibility and efficiency.

LIPP GmbH was deliberately chosen as the supplier for central tank components, particularly in the areas of fermentation and storage. According to the customer, the decisive factors for this choice were:

* The high quality and tightness of the stainless steel containers manufactured by LIPP, which offer maximum safety for the sensitive biological process of fermentation.

* The well-proven double seam system, which can be ideally integrated into the modular system concept.

* LIPP’s many years of experience in industrial and agricultural biogas plant construction.

* The ability to implement specific requirements such as pressureless design, technical hygiene requirements and ATEX compliance.

A 400 m³ LIPP Gas Accumulator was constructed. This type of LIPP Gas Accumulator for pressureless gas storage was developed in the early 1970s and has been implemented in over 300 projects worldwide. Depending on the gas volume, sizes from 50 to 5,000 m³ are possible.

Furthermore, this project resulted in the creation of a 800 m³ LIPP Universal Digester, which essentially consists of a stainless steel tank made from the composite material VERINOX®.

VERINOX® consists of steel galvanised on both sides and a stainless steel lining, e.g. 1.4571 [316Ti] or 1.4539 [904L] on the side in contact with the medium.

The LIPP Universal digester is ideal for a modular plant design. The wall heating and insulation are mounted on the outside and are easily accessible. Heat input is optimised thanks to the good thermal conductivity of the steel. The tank is covered by a self-supporting stainless steel membrane roof, which is particularly resistant to corrosion from aggressive media.

The collaboration with LIPP GmbH has enabled us to establish the technical basis for stable, safe and efficient plant operation. The LIPP Tanks used not only meet the highest technical standards, but also contribute significantly to the ecological and economic success of this showcase project.
