Your engineering office for fermentation plants,
thermal engineering and process optimization.

Your benefits

As an independent planning office, we advise and support investors, farmers and municipalities in a comprehensive way. We plan and supervise construction projects in the fields of process engineering, co-generation, heating and gas feeding. Whether it is new buildings or the repowering of existing plants, our focus is on the design of a customised, efficient and economical system solution. In doing so, all factors such as location, substrate, approval situation, infrastructure and economy must be considered and interwoven into an individual concept in the light of current technical possibilities.

We attach great importance to a timely, cost-efficient and quality-assured implementation. Convince yourself of our know-how and comprehensive range of services of technical consulting, feasibility studies, direct planning services according to HOAI (German fee regulations for architects and engineers), due diligence, project management, and general planning. All planning and implementation processes are carried out independently of any influence by the interests of company or product suppliers.

The special process engineering requirements of the planning task and their economic goals are the focus of our project implementation. A reliable problem analysis, specialist advice, consistent scheduling and a transparent cost management take centre stage when it comes to our service spectrum.

Coordination and control

In the context of awarding of contract to a general contractor, it is advisable to transfer the coordination and control of the project to an external partner. As a technical consultant, a controller and associate, we accompany your project from approval phase to engineering to acceptance. We see ourselves as business partners of the client and provide competent and loyal support in all issues regarding project planning and implementation.

More advantageous overall projects 

Against the backdrop of rising raw material costs and personnel and operating expenses, plants have to be built cost-optimised. Because a custom-made planning, an independent construction tendering and a tight monitoring of construction help to reduce production costs, projects may be implemented in a much more cost-effective manner by individual contract awards and cost controlling.

Influence on the kind of construction

During planning and tendering of the project, GreenLine, the client and current technical innovations are incorporated with regard to material and execution. This ensures that both subcontractors and technology are optimally adapted to the requirements.

Construction supervision and implementation time

An essential point in project completion is the construction supervision. Greenline coordinates the individual trades and reviews whether they are built according to the state of the art with the required quality and according to the planning and description contractually agreed. Greenline draws up a time schedule and monitors its compliance. Greenline supports in the correction of faults, assists with the contractual acceptance of the services, takes on-site measurements in cooperation with the construction companies and checks the technical and arithmetic correctness of the invoices. Planning times and a tight coordination of the subcontractors significantly reduce implementation times. The free choice with regard to the subcontractors means that capacities can be planned more easily and more economically.


Greenline is obliged to be the client's "trustee". As part of its role as a trustee, Greenline has to advise independently on the development of the project, recommend the best subcontractors for the building, indicate the most suitable construction products, ensure flawless construction works and represent the client's interests towards the subcontractors.
