Processes and technologies in the bioeconomy

The state of Baden-Württemberg is characterised by strong economic expertise in the field of plant and mechanical engineering as well as excellent research institutions in the fields of biology, biotechnology, bioprocess engineering and chemistry. These form an excellent basis for a sustainable economy by promoting technology development and innovation for tomorrow’s bioeconomy.

Glossary

  • A Catalyst is a substance which selectively accelerates a specific chemical or biochemical reaction without being consumed by the overall reaction.
  • There are two definitions for the term organism: a) Any biological unit which is capable of reproduction and which is autonomous, i.e. that is able to exist without foreign help (microorganisms, fungi, plants, animals including humans). b) Definition from the Gentechnikgesetz (German Genetic Engineering Law): “Any biological unit which is capable of reproducing or transferring genetic material.“ This definition also includes viruses and viroids. In consequence, any genetic engineering work involving these kinds of particles is regulated by the Genetic Engineering Law.
  • The term metabolism includes the uptake, transport, biochemical conversion and excretion of substances within an organism. These processes are necessary to build up the body mass and to meet the energy demand of the body. The opposed processes of metabolism are called anabolism and catabolism. Effectiveness of several enzymes could be catabol and anabol. Within one biochemical pathway they cannot work in both directions at the same time.

The creation of a biobased economy requires process innovations that enable the efficient utilisation of raw and residual materials. Process innovations in the bioeconomic sense include processes and technologies that use biogenic raw and residual materials as the starting substrate, as well as biobased processes that exploit the metabolic activities of living organisms such as microorganisms, bacteria or algae. In both cases, the goal must be to develop sustainable, flexible and cost-effective processes that can be scaled up quickly to industrial scale.

A huge variety of methods and processes is used in the bioeconomic area. The overall aim is to achieve a coupled and cascading use of biogenic raw material resources and residual materials. The main focus is on simple and combined chemical, physical and biotechnological/-catalytic conversion technologies.

The biorefinery concept is an intelligent and promising solution for replacing oil with biomass as a raw material to produce fuels, power, heat and chemicals. Biorefineries integrate different biomass conversion processes and technologies. The biorefinery approach is based on a holistic utilisation of biomass for producing value-added (intermediate) products. Thus, biorefineries aim for zero-waste biomass utilisation by applying efficient technologies to convert biomass into energy and products.

However, a biorefinery does not necessarily need to combine all process steps in one plant. Depending on the location, even small, modular plants can be the right choice for creating value with biomass. It is important that biomass digestion and conversion processes are resource-tolerant and flexible to take account of different biomass compositions and quantities of waste and thus process different material flows in one process step.

As the situation stands, new and improved technologies and processes are mainly being implemented in pilot and demonstration plants. Further efforts are needed to transfer applications to an industrial scale.

Processes and technologies in the bioeconomy

    Natural gas is a more climate friendly fuel than raw materials such as coal and petroleum. Nevertheless it is also a fossil fuel that generates anthropogenic CO2 emissions. In a collaborative project at the Karlsruhe Institute of Technology, scientists and engineers are concentrating on finding out how biogenic residues and waste materials such as wood, sewage sludge and biomass mixtures can be turned into alternative gaseous fuels.

    Novel biomass materials suitable for various applications need to be developed in order to establish a biobased raw material platform within the bioeconomy. These biobased materials must be able to compete with conventional fossil fuel-based materials, both from a technological and economic point of view. Researchers at the University of Hohenheim are working on the development of conductive carbon materials from biomass with the long-term goal of making the substitution of fossil electrode materials in high-capacitance energy storage systems ready for market.

  • Article - 13-Mar-2017

    Biogas plants have become a familiar sight in Baden-Württemberg's rural areas. It might therefore be expected that broad experience exists in the comprehensive evaluation of this type of energy generation from renewable resources or organic materials. However, scientists draw a very differentiated picture. It is difficult to make any generalisations, although the analysis of individual facets can provide further help.
