What bonnhoff buchenhof bioenergie gmbh & co. kg does

Bonnhoff Buchenhof Bioenergie GmbH & Co. KG is a privately held German limited partnership (GmbH & Co. KG) that operates an agricultural biogas plant in Klein Offenseth-Sparrieshoop, Schleswig-Holstein. Since late 2006, the facility has fermented manure and energy crops — corn, grass, cereals — sourced from its own 440 hectares plus approximately 250 hectares of purchased corn, into methane-rich biogas. The gas is combusted in two combined heat and power (BHKW/CHP) units with a combined thermal capacity of 670 kWth, generating renewable electricity fed into the public grid under Germany's EEG (Renewable Energy Sources Act) feed-in tariff regime.

The plant's distinguishing design is a cascaded heat utilization system: a 1.5 km dedicated gas pipeline installed in 2007 delivers biogas to a satellite CHP unit located at the heating center of Rosen Kordes, Europe's largest rose tree nursery, providing approximately 7 million kWh of year-round greenhouse heat annually. The return-flow heat from this greenhouse circuit is then used to heat municipal buildings — a community center, a school with gymnasium, and a fire station — supplying an additional ~500,000 kWh per year. This dual-channel architecture, recognized with a 2009 Sonderpreis Energieeffizienz-Projekte from the Innovationsstiftung Schleswig-Holstein, achieves near-complete thermal utilization and is operated by a team of three employees.

The business model is a hybrid of regulated grid feed-in revenue and bilateral heat supply contracts with one anchor commercial customer (Rosen Kordes) plus a municipal heat offtake. The company is structured around two operational pillars: biogas production and arable farming. No external investors, parent company, funding rounds, or acquisitions are disclosed; the entity is registered in the commercial register at Amtsgericht Elmshorn (HRA PI-5144) and operates under family ownership with Björn Bonnhoff as the named data protection officer and primary contact.

Revenue model

1. Renewable Electricity Generation and Grid Feed-in: The biogas plant generates renewable electricity fed into the public electricity grid since late 2006. Revenue is derived from selling renewable electricity, likely under Germany's EEG (Renewable Energy Sources Act) feed-in tariff scheme.
2. Biogas Heat Sales to Commercial and Municipal Customers: The facility sells biogas-derived thermal energy to Rosen Kordes (Europe's largest rose tree nursery) for greenhouse heating (approx. 7 million kWh/year), and to the municipal community center, school with gymnasium, and fire department (approx. 500,000 kWh/year). The municipal customers utilize the return flow from the greenhouse heating circuit.

Core offering

Bonnhoff Buchenhof Bioenergie operates an agricultural biogas plant that ferments manure and renewable raw materials (corn, grass, cereals) into biogas, which is then converted in two combined heat and power (BHKW) units with a total thermal capacity of 670 kWth. The facility generates renewable electricity that is fed into the public grid (since late 2006) and supplies thermal energy via a dedicated 1.5 km gas pipeline to Rosen Kordes (Europe's largest rose tree nursery) for greenhouse heating, with surplus heat distributed to municipal buildings (community center, school with gymnasium, fire department).

Product overview

Bonnhoff Buchenhof BioEnergie GmbH & Co. KG operates an agricultural biogas plant with two CHP units (670 kWth total thermal output) that generates renewable electricity for the public grid since late 2006. The company operates across two business segments: biogas production and arable farming on 440 hectares. The biogas plant produces methane-rich biogas from manure and renewable raw materials, which is converted to electricity and heat. Waste heat is supplied year-round to Rosen Kordes (Europe's largest rose tree nursery) and community buildings including a school, gymnasium, fire station, and community center. A satellite CHP unit was installed in 2007 at Rosen Kordes' heating center via a 1.5 km gas pipeline.

Products and services

• Biogasanlage (Biogas Plant) — Renewable Electricity and Heat Generation Agricultural biogas plant that ferments manure and renewable raw materials (corn, grass, cereals) to produce methane-rich biogas, which is converted in two combined heat and power units. The plant has been supplying renewable electricity to the public grid since late 2006 and provides thermal energy for off-takers.
• Satelliten-BHKW (Satellite CHP) at Rosen Kordes Heat Center Dedicated satellite combined heat and power unit installed at the customer site (Rosen Kordes rose nursery) and connected via a 1.5 km gas pipeline to the main biogas plant. It supplies approximately 7 million kWh of renewable heat per year to heat greenhouses and outbuildings as year-round base thermal load.
• Municipal District Heat Supply (Return-Flow Circuit) Cascaded heat distribution service that supplies renewable biogas heat to municipal public buildings in Klein Offenseth-Sparrieshoop — specifically the community center, school with gymnasium, and fire department — using the return flow from the greenhouse heating circuit. Approximately 500,000 kWh per year.
• Ackerbauprodukte (Arable Farming Products) Agricultural products grown on 440 hectares of land as a parallel business segment alongside biogas production: 100 ha grass, 280 ha corn, 60 ha cereals (also as whole-crop silage). Approximately 250 hectares of additional corn is procured annually from external farms. The company is trialing millet and silphie as alternative energy crops.

Quantifiable outcome

• Thermal energy utilization: ~7 million kWh/year supplied to greenhouse operation; ~500,000 kWh/year to municipal buildings; total of ~7.5 million kWh renewable heat delivered annually

Partnerships

Two partnerships are on record, tiered minor and core.

• Gemeinde Klein Offenseth-Sparrieshoop (municipal government)minorStrategic or Co-development Partner · 1 January 2007The municipality of Klein Offenseth-Sparrieshoop receives approximately 500,000 kWh of renewable biogas heat per year via the return flow from the greenhouse heating circuit, supplying the community center, school with gymnasium, and fire department. This arrangement provides low-cost renewable heat to municipal buildings, representing a community benefit partnership that leverages existing infrastructure at no incremental cost.
• Rosen KordescoreStrategic or Co-development Partner · 1 January 2006Rosen Kordes, Europe's largest rose tree nursery, is the primary commercial heat customer of the Buchenhof biogas plant. Since the plant's inception in late 2006, Rosen Kordes has utilized the biogas-derived electricity and thermal energy to heat its greenhouses and outbuildings. In 2007, a dedicated 1.5 km gas pipeline was constructed from the biogas plant to a satellite CHP unit located at the Rosen Kordes heat center, supplying the year-round thermal base load for approximately 7 million kWh of greenhouse heat per year. This is a long-term strategic relationship with a flagship commercial customer, representing the core revenue-generating heat off-take partnership.
