More efficiency and sustainability with Digital Enterprise

Alternative raw materials such as biomass and renewable sources of energy such as solar, wind, and hydro power are becoming more and more important for the global supply of power and raw materials – as alternatives to crude oil that make economic and ecological sense. Biorefineries play a key role in this context. Processes based on renewable sources of energy can be called green refineries.

Efficient design of bioprocesses

A biorefinery is comparable to an oil refinery: raw materials are first pretreated and processed, then separated into components, and ultimately converted or refined. Biomass refineries improve the energy footprint and protect the environment. More and more chemical companies are looking for efficient, safe, and high-quality methods to produce or refine their products on the basis of biological processes. In biotechnological production, living bacteria and plant material are suitable as starting materials. Fat and vegetable oil can also be used as raw material, e.g. as in a biodiesel plant.

Research for greater sustainability

To this end, renewable raw materials or microorganisms are used to obtain high-quality compounds through synthesis or fermentation. These compounds are then used in the production of bioplastics based on lactic acid (polylactide acid, PLA). A portion of the biomass is used in the plant not as a material but as a source of energy.

High standards for the processes

Development of biologically based products requires a great deal of time and money. It is necessary to observe statutory regulations and meet high quality requirements. Highly complex and sensitive laboratory procedures often have to be scaled to industrial size. It is important to commission the plant easily and quickly – using COMOS Engineering, for example – as well as to control the processes flexibly and cost efficiently with SIMATIC PCS 7 or SIMATIC PCS neo.

Processes become digital

The full potential of biotechnological production can be exploited through the digitalization of biological processes. The centerpiece of the digital plant is its digital twin – a precise map of the virtual biorefinery and the data documentation over the entire value flow and lifecycle. With our simulation tools, processes and plant components can be simulated and continuously optimized through repeatable tests. Intelligent data analyses based on digital applications and their rapid implementation accelerate innovation and boost productivity while also helping to enhance product quality.

Bio-/Green refineries

Our entire portfolio of opportunities at a glance

The task of bio-/green refineries is to make use of biomass and renewable energies by converting them into various intermediate and end products by utilizing a wide variety of technologies. We support operators of this refineries in ensuring that the processes in their plants run as flexibly, efficiently, and sustainably as possible. We are convinced that the resulting opportunities for climate protection, value creation, and resource efficiency are enormous. There are as many forms of renewable energy as there are ways of using them. Various biofuels, energy sources, and green chemicals can be produced from such biomass as corn, grass, algae, or solid waste and from such renewable sources as wind, solar, and hydro power. The high-quality by-products can also be used for animal feed or fertilizers.

Power to Gas

Conversion of excess energy by electrolysis into "green" hydrogen which can be used in varied ways.

Power Plant

Generation of electrical and/or thermal energy by combustion of biogas/synthesis gas or biomass in power plants


Organic materials are converted by means of microorganisms or enzymes, e.g. for bioethanol.


Gasification of organic material and use of the synthesis gas, e.g. for chemical products, synthetic fuel or power generation in power plants.


Bio-refineries transform biomass or "green" gas into "green" chemistry, i.e. into biofuels and bioenergy. The process uses by-products efficiently.


Biodiesel, bioethanol, or biogas – biofuels are an environmentally friendly alternative to fossil fuels. 


Biomass conversion produces valuable by-products that can be further used. Find out how we can make flexible production easier for you.


Green chemistry is the key to sustainable production with fewer harmful effects to the environment and less energy waste. 


Electricity and heat generated from biomass come from biomass heating plants, biomass power plants, combined biomass heat and power stations, biogas plants, and biomass combustion plants, for example. 

Portfolio for bioethanol production

Perfectly tailored for fermentation and distillation
Glucose (such as in sugar cane) or starch from plants such as corn can be converted into ethanol and other alcohols of any desired concentration by means of fermentation and distillation. Nowadays, more and more non-food biomass is being used for this type of production. Our integrated portfolio for automation, digitalization, and energy management is ideal for maximizing safety, flexibility, and efficiency. It is perfectly tailored to all areas of bioalcohol production.

Precise and safe from input to output

Even in the first process step of raw materials handling, we use precise processes to support delivery, weighing, analysis, and storage of feedstocks such as corn, sugar cane, vegetable waste, wood or straw. This of course also applies to residual materials and by-products, which can be further marketed as, for example, animal feed or high protein. In the entire field, even in hazardous zones, you can rely on our robust process instrumentation as well as safe drive and switching technology. Within the framework of energy management, we support combustion of residues and by-products for energy recovery and steam generation. These electrical or thermal energies increase the overall efficiency of your bioethanol plant.

Using bioenergy as a raw material with the Digital Enterprise

Whether they are solar parks or wind farms – renewable energy sources produce surplus electricity inexpensively. In power-to-gas plants, this electricity can be temporarily stored and converted into “green,” renewable hydrogen. Power-to-gas is thus regarded as a key technology for sustainably reducing CO2 emissions and for the success of the energy revolution.

Turning hydrogen into a resource

Hydrogen is an important raw material for the chemical industry and is primarily extracted from natural gas, a process which is not environmentally friendly. Power-to-gas plants offer the advantage of generating hydrogen and methane from the regenerative surplus of green electricity and economically storing these substances for later use in a variety of applications. Electrolysis is the key technology here. Our portfolio is ideally suited for automating and safely operating power-to-gas plants. It also includes various solutions for feeding into the natural gas grid, generating electricity, or producing “green” ammonia.
