Working towards a hydrogen economy with a wastewater biorefinery: the SmartBioH2-BW project

A biorefinery that uses industrial wastewater and residual material streams is being built in Rheinfelden (Baden). It will have two interlinking bioreactors and will synthesize biohydrogen as well as organic basic materials such as carotenoids and proteins. SmartBioH2-BW is a pilot project run by the Urban and Industrial Biorefineries initiative and funded by the Baden-Württemberg Ministry of the Environment, Climate Protection and Energy Sector.

Basic chemicals, which are needed as raw materials for a wide range of products such as medicines and detergents, can currently only be produced with an enormously high input of energy and raw materials. In many cases, fossil fuels and raw materials are still used. The extraction of chemical substances alone requires high temperatures, expensive catalysts made of precious metals and, in some cases, environmentally harmful starting materials.

The construction industry consumes large amounts of energy resources and produces tons of waste. At the Solar Decathlon Europe 21/22 university competition, students and researchers from KIT are eager to demonstrate that the building sector is already compatible with a functioning circular economy. The task of the interdisciplinary “RoofKIT” team is to convert previously unused roofs of buildings into usable spaces.

CO2 from the air as a raw material for chemicals

A Fraunhofer team has successfully produced a dye using CO2 adsorbed from the air. The aim is to move towards a climate- and resource-friendly circular economy. Chemicals, as well as fuels, can be produced cost-effectively using this process. How does the technical process work, and what opportunities does it open up?

Researchers find the enzymatic link in the formation of methane from fatty acids by cooperating microorganisms. Microbial production of methane from organic material is an essential process in the global carbon cycle and an important source of renewable energy. This natural process is based on a cooperative interaction between different types of microorganisms: the fermenting bacteria and the methane-producing archaea.

An international research team has calculated the potential for material efficiency strategies in residential buildings and passenger cars. Up to two-thirds of global emissions could be saved in these areas, provided that appropriate strategies are consistently implemented.

The EU funded research project HyFlexFuel recently succeeded to produce biocrudes via hydrothermal liquefaction (HTL) from a variety of biomasses, including sewage sludge, food waste, manure, wheat straw, corn stover, pine sawdust, miscanthus and microalgae in a pilot-scale continuous HTL plant at Aarhus University (Denmark).

On 8 February, the European Parliament adopted its Own Initiative Report on the Circular Economy which recognised the role of bioplastics for the future. Amongst other issues highlighted, the MEPs emphasised the potential role of bio–based and biodegradable and compostable plastics in the circular economy whilst noting that bio-based and/or biodegradable plastics alone will not provide a solution to the environmental concerns related to plastics.

Agrivoltaics enables the dual use of arable land: Photovoltaic modules, which are mounted on a structure, generate renewable electricity and underneath agricultural crops grow. The approach increases land efficiency and could mitigate conflicts over the use of arable land in the future. A new guideline provides up-to-date information on the technology, its potential and the current state of development.
