Celeriac and electricity: dual-use system on arable land

Food or fuel? Potatoes or electricity? In addition to growing energy crops for biofuel and biogas production, open space solar plants also compete with food production when it comes to land use. Agrophotovoltaics (APV), i.e. the dual use of arable land, can mitigate the conflicting interests of agriculture and open space PV systems. APV-RESOLA is a pilot project aimed at investigating the efficiency of this dual use.

Efficient production of fuel from biogenic residues

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.

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.

Chicory root and its potential in bioplastics production

Researchers from the University of Hohenheim use waste in the form of chicory roots to extract basic chemical building blocks for producing nylon and plastics. Hydroxymethylfurfural (HMF) is one of 12 platform chemicals used to produce plastics. The raw material obtained from the chicory root improves the plastics’ environmental performance, notably because it is an oil substitute and does not compete in any way with food production.

Biogas from unicellular green algae

Microalgae are among the most promising sources of sustainable, carbon-neutral biofuels for the future. They are already being used as feedstock for producing biogas, biodiesel, bioethanol and kerosene, but the associated production methods consume a great deal of energy and are rather costly. Dr. Nikolaos Boukis from the Karlsruhe Institute of Technology (KIT) is working on the development of a sophisticated, thermochemical process with an…

Overview

Environmental analytics

Nature provides the material basis for a bioeconomy. Preventive and production-integrated environmental protection will therefore become even more important in a bioeconomy. Powerful analytical systems that can be used in industrial processes or in the field will provide information about soil, air and water quality. Environmental analytics and monitoring are crucial for the bioeconomy.

Overview

Materials and chemicals

Biomass can be used to produce chemicals, fibres, pigments and plastics. These products are either identical to their petroleum-based counterparts or have completely new properties. Biorefineries will play a key role in the transition to a bioeconomy. There is great expectation placed on the potential ability to convert the countless carbon compounds in biomass into chemicals and material components.

Overview

Bioenergy

Examples of fuels produced from biomass are biomethane, renewable natural gas (RNG), biogenic hydrogen, biokerosene, biomethanol, bioethanol and higher alcohols. However, in future, care must be taken to avoid the well-documented conflict between crops used for food and those used for fuel production. The bioeconomy strategy therefore calls for only using the biomass that cannot be used for producing food. Microalgae, biowaste and residual…

Overview

Politics, ethics and economy

Agricultural land on Earth is limited. However, the increased need for food and feed coupled with the increasing use of biomass feedstocks leads to areas of conflict such as intensive farming, biodiversity loss, land grabbing and indirect land use change. Governments are faced with the major challenge of having to deal with and shape the bioeconomy while taking equally into account the ecological, economic and ethical concerns and integrating…

Overview

Biobased resources

A major goal of the bioeconomy is to use larger quantities of biobased raw materials to produce energy, transport fuels and feedstock for industrial processes. This requires detailed analyses, simulations, concepts and processes. Major focus needs to be placed on issues relating to crop production, biomass potentials, land surface requirements, conversion technologies, biobased value creation networks and food security. Agriculture, forestry,…
