Waste management - Waste must not pollute.

Waste management plays an important role in the economy and steadily gains in importance. Whether in industry or in private households: Waste accumulates everywhere that must be recycled as a matter of priority or sent for final treatment as residual materials. Sustainable management means conserving resources by recycling raw materials and thus supporting a functioning circular economy. Particularly in a resource-intensive sector such as the construction industry, this is our top priority.

PORR's environmental technology specialises in the safe disposal of hazardous and non-hazardous waste. We have a wide range of services from mineral processing to disposal and final landfill. To ensure a smooth process, we build and own our own modern facilities. Our environmental technicians have many years of experience in waste management in the construction industry and find an individual solution for every task.

Assessment of contaminated sites - Knowing what lies below.

We at PORR Umwelttechnik know that a professional and complete investigation of contaminated sites is a basic prerequisite to avoid any surprises during construction.

We offer our clients the entire spectrum, from determination of contaminated sites to planning and project planning to environmental chemistry, boring tasks and construction as well as geothermal energy. During determination, we take care of planning and executing property assessments regarding subsoil contamination of all kinds, evaluation concerning current standards and laws as well as cost estimation of securing and rehabilitation measures based on previous surveys. Adding to this are services in environmental chemistry, exposure drilling, well construction as well as the planning and construction of geothermal energy systems as an alternative energy source for building heating or cooling.

Environmental clean-up - No contamination passed on.

The securing and remediation of contaminated sites is a key focus of PORR Umwelttechnik's work. Complex contamination at contaminated sites requires intensive preparation in terms of hazard assessments, variant studies, remediation planning or the development of economic and ecological measures to treat the contaminated protected assets. Often, a combination of several safeguarding and remediation procedures is necessary. 

In addition to pre-treatment, clearance and disposal, our services also include enclosure with sealing walls, immobilisation, waste treatment, groundwater purification, soil vapour extraction and in-situ and ex-situ microbiological treatment.

In many cases, pollutants, artificial mineral fibres and asbestos have to be removed from buildings before demolition work. Low-bound asbestos products in particular, such as spray asbestos, place high demands on the protection of personnel and the environment during removal from the objects. Our specialists, trained in accordance with TRGS 519 and TRGS 521, have many years of experience in this field.

Demolition - Properly recycling and disposing of old stuff.

PORR Umwelttechnik has many years of experience in carrying out industrial dismantling and demolition work. We offer our clients a wide range of services: from ecological material separation and disposal to complete gutting and deconstruction. Here we excel particularly in technically demanding projects that require innovative deconstruction concepts. 

We also specialise in urban mining, the professional dismantling of power plant sites and large industrial areas. Here, it is important to identify potential objects as secondary raw materials at an early stage, to quantify the secondary raw materials they contain and to prepare economic feasibility studies based on innovative technical recovery variants. 

From planning to implementation - PORR Umwelttechnik offers all services from a single source.


Ensuring quality requirements is a top priority at PORR. This is also evidenced by our certificates and approvals. In order to always be up to date, our certificates and approvals are reviewed and updated on a regular basis through external audits and independent certification companies.
