What Heim Holding Gmbh & Co. Kg does

Heim Holding GmbH & Co. KG (operating as HEIM-Gruppe) is a fourth-generation, family-owned German industrial group headquartered in Ulm that operates an integrated network spanning construction (road and civil engineering, paving, cast asphalt), construction-materials extraction and processing (quarries for gravel, sand, quartz sand, crushed stone, asphalt, clay), recycling (construction materials, plastics, food waste), renewable energy (eleven biogas plants, floating and ground-mounted photovoltaic installations, district heating), and supporting agriculture (dairy and arable farming feeding biogas substrates and digestate cycles). The group employs approximately 550 people across more than 30 sites in four regional clusters — Ulm/Donautal, Berlin/Brandenburg, Altenburger Land, and Oberlausitz — and produces over 103 million kWh of renewable electricity per year, enough to supply roughly 25,000 households, while avoiding up to 54,000 tonnes of CO₂ annually.

The business model is project- and transaction-based B2B selling direct from owned works and field-account relationships to construction contractors, municipalities, agricultural operations, energy off-takers, and private customers. Revenue is generated across five interconnected streams: civil and road construction services; aggregate, asphalt and specialty material sales; recycling and disposal fees; renewable energy feed-in and heat supply; and agricultural output. Pricing is project-specific and not publicly disclosed. The group has invested heavily in circular-economy integration — for example, biogas heat drying quartz sand at Nobitz, food-waste recycling feeding biogas substrates at Klein Eichholz, and demolition concrete being mineralized with CO₂ under the CORE project in partnership with neustark AG and Land Berlin — and has executed multiple acquisitions plus the 2024 CEMEX joint venture to scale these capabilities. Ownership remains entirely within the Heim family across four generations, with no external shareholders or funding rounds disclosed.

Core offering

HEIM-Gruppe is an integrated industrial group that extracts and processes construction materials (asphalt, gravel, sand, quartz sand, crushed stone, clay, loam) and delivers road and civil engineering services through its own construction subsidiaries. Beyond construction, the group operates 11 biogas plants plus photovoltaic installations under its pure power sub-brand, runs construction material, plastic and food waste recycling operations, and produces CO2-reduced recycled concrete via the CORE project in partnership with neustark AG. Revenue derives from construction project execution, ex-works materials sales, district heat and electricity supply, and recycling/ disposal fees.

Product overview

Heim Holding GmbH & Co. KG is a family-owned enterprise group with over 100 years of history, operating an integrated network across construction (Tief- und Straßenbau), construction materials (Baustoffgewinnung), renewable energy (pure power biogas and photovoltaic plants), and recycling (construction materials, plastic, and food waste). The company offers construction materials including quartz sand from Nobitz, gravels, sands, asphalt, cast asphalt, clay/loam, and recycled construction materials. Its renewable energy subsidiary pure power operates 11 biogas plants producing over 103 million kWh annually. The CORE project develops CO₂-reduced recycled concrete using neustark mineralization technology. The group also operates agricultural operations supporting biogas production and maintains a joint venture with CEMEX for expanded recycling operations. Products span from raw material extraction through construction services to end-of-life recycling, embodying a circular economy approach.

Broad incumbents

• HOCHTIEF AG: Major German construction company (subsidiary of ACS Group) with strong civil engineering and infrastructure presence. Overlaps with HEIM in road construction, asphalt, and aggregates; broader geographic and segment reach.
• Holcim Group: Global construction materials leader with strong circular construction and ECOPact low-carbon concrete product lines. Direct competitor in the CO2-reduced concrete category that HEIM's CORE project targets.
• Heidelberg Materials AG: One of the world's largest building materials groups (cement, aggregates, ready-mixed concrete) headquartered in Heidelberg. Competes with HEIM in aggregates and concrete, with a major push into low-carbon cement (evoZero) directly threatening HEIM's CORE positioning.

Direct peers

• CEMEX, S.A.B. de C.V. Global building materials company and HEIM's JV partner in CEMEX HEIM RC-Baustoffe GmbH & Co. KG (2024). Direct competitor in aggregates and concrete, particularly in low-carbon concrete product lines.
• Scholz Recycling GmbH: German family-owned recycling and raw materials trading group. Comparable in construction and demolition waste recycling as a revenue stream and integrated materials recovery operations.
• STRABAG SE: Austrian-based construction group with significant German operations in road and civil engineering, tunneling, and materials. Comparable in core civil engineering services and DACH geographic footprint.
• Remondis SE & Co. KG: Germany's largest privately-held recycling, waste management, and water services company. Comparable in recycling operations (particularly construction materials and food/organic waste) and family-ownership structure.
• EGGERS-Gruppe: Private German group combining construction, civil engineering, and recycling operations in northern Germany. Comparable in diversified circular-economy positioning and Mittelstand scale.
• GP Günter Papenburg AG: Private German family-owned group with ~3,000 employees operating across construction materials, civil engineering, recycling, and ready-mix concrete. Closest comparable in business model, ownership structure, and integrated value chain, though materially larger in scale.

Regional players

• PORR AG: Austrian construction group with significant German operations in civil engineering, road construction, and building materials. Operates in DACH but is headquartered in Austria, making it a regional rather than direct German competitor.
