Heidelberg Materials ETR: HEI

Cement, concrete and aggregates with circular raw materials, alternative fuels and construction recovery

HM
Public materials brief.

Heidelberg Materials has a real concrete-to-concrete pathway, but the evidence needs to stay regional. Its ReConcrete process separates waste concrete into sand, gravel and hardened cement paste, while the company reports 29.0 million tonnes of secondary materials in 2025 across its businesses. The right decision is one demolition stream and one region where feedstock quality, processing yield and product specification can be verified together.

Heidelberg Materials 2025 reporting describes resource efficiency, co-processing of waste materials, concrete recycling, alternative fuels and secondary raw materials across its business lines. The company describes ReConcrete as a process that can separate waste concrete into sand, gravel and hardened cement paste, with the paste usable as a raw material in clinker and cement production. Public reporting does not establish one regional construction stream ledger connecting demolition source, processing yield, product specification, customer project and next-life outcome.

Material inputs to resolve

  • Limestone, clay, aggregates, water, energy, alternative fuels, waste materials and demolition concrete
  • Quarrying, kiln, grinding, batching, transport, construction and demolition data
  • Waste concrete, asphalt, glass, used tires, biomass and other qualified industrial streams

Outputs and residuals to resolve

  • Cement, clinker, ready-mixed concrete, aggregates, asphalt and building systems
  • Construction waste, kiln residues, recovered aggregates and cement paste
  • Regional yield, product qualification and project-level recovered-content evidence remain open
First decision: Choose one region and one recovered stream, such as waste concrete, asphalt or alternative raw material. Map source, processing yield, product specification, customer project and next life.

Circularity signal

Heidelberg Materials describes resource efficiency, waste co-processing and concrete recycling as core circular-economy work.

Process signal

ReConcrete separates waste concrete into sand, gravel and hardened cement paste, which can be evaluated for return to construction-material production.

Product signal

The company describes secondary raw materials and circular alternatives across cement, concrete and aggregates.

Evidence boundary

Group reporting does not establish one regional recovered-material ledger from demolition through a qualified product.

Decision boundary

Heidelberg Materials has a real concrete-to-concrete pathway, but the evidence needs to stay regional. Its ReConcrete process separates waste concrete into sand, gravel and hardened cement paste, while the company reports 29.0 million tonnes of secondary materials in 2025 across its businesses. The right decision is one demolition stream and one region where feedstock quality, processing yield and product specification can be verified together. The public record supports one bounded next move: Choose one region and one recovered stream, such as waste concrete, asphalt or alternative raw material. Map source, processing yield, product specification, customer project and next life. It does not establish a buyer, commercial approval or supply agreement.
