Raw materials from wastewater - 21/12/2022

Wastewater treatment plants as biorefineries: the RoKKa project

RoKKa, a joint project coordinated by the Fraunhofer IGB, is testing methods for recovering raw materials such as phosphorus and nitrogen compounds to produce fertiliser from municipal and industrial wastewater in a climate-neutral way. These new methods are being investigated under real conditions at wastewater treatment plants in the Ulm area with a view to developing them into sustainable biorefineries.

Optical technologies & artificial intelligence: University of Hohenheim, Bosch, Amazonen-Werke, and BASF Digital Farming conducts research into high-performance sensors for smart herbicide treatment

Whether in drinking water, food or even in the air: plastic is a global problem - and the full extent of this pollution may go beyond of what we know yet. Researchers at the Karlsruhe Institute of Technology (KIT), together with partners from the Netherlands and Australia, have reviewed conventional assumptions for the transport of plastic in rivers.

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 glass facade of a high-rise building can get so hot that you can fry eggs on it – a major factor in the overheating of our cities. At the same time, flood events such as torrential monsoon rains cause billions of dollars of damage annually. On October 4, 2022, a solution to both problems was presented at the University of Stuttgart.

Fossil raw materials are limited and not available and extractable everywhere in the world – as we are becoming acutely aware of right now by the example of fossil fuels and rising energy prices. Renewable raw material sources will therefore play an increasingly important role in the future: as energy sources, but ideally also as suppliers of building blocks for more environmentally compatible chemicals and materials.

In its statement of September 2, 2022, the Bioeconomy Council of the German government condemns the Russian war of aggression on Ukraine and points out ways in which the resulting food and energy crisis can be alleviated with the help of the bioeconomy.

Project BW2Pro - 29/08/2022

Biowaste to Products: biorefinery transforms biowaste into new products

In 2020, Germany’s population collected over 5 million tonnes of biowaste. Most of this was composted, and some was fermented into biogas. Scientists in Baden-Württemberg think there's room for more. Within the project ‘Biowaste to Products’ (BW2Pro) they want to transform biowaste into new products in a biorefinery. The idea is to produce biodegradable plant pots, mulch material, fertilisers, enzymes and biobased plastics in addition to…

Lentil cultivation in a producers’ association - EIP-AGRI Rhizo-Linse project - 23/05/2022

From cultivation to market – lentils from the Swabian Alb

Complicated cultivation, fluctuating yields and complex cleaning: Leisa – as lentils are called in Swabian – are demanding. So to produce lentils economically, 130 farmers in the Swabian Alb have joined forces and set up the organic producers’ association Alb-Leisa. Their lentil harvests are processed and marketed by a company called Lauteracher Alb-Feld-Früchte.

Lentil cleaning - EIP-AGRI Rhizo-Linse project - 26/04/2022

Lentil cleaning in the Altdorf mill

The Altdorf mill, just under 7 km south of the city of Böblingen, has operated lentil cleaning facilities since 2019, the year that the Sessler mill in Renningen, 20 km further north, ceased all operations including lentil cleaning. After receiving a number of enquiries from farmers and local mills, brothers Karl and Jörg Ruthardt took a chance and launched a lentil cleaning operation in addition to their mill and farm shop business.

pre-start-up company Wheyfinery - 13/04/2022

Acid whey as a valuable raw material for platform chemicals and more

There is not much you can do with acid whey, which is why several million litres of it are disposed of every year. This is both costly and not sustainable. However, researchers at Tübingen University have shown: acid whey can be used to produce precursors for biofuels, fine chemicals and antimicrobial livestock feed additives. They have set up the pre-start-up company Wheyfinery in an endeavour to make their scalable biorefinery concept…

The "carbonauten minus CO2 factory 1" will start production of 4,000 t of CO2-reducing plastic granules annually at favorable prices in summer 2022.

The Ministry for the Environment, Climate Protection and the Energy Sector is funding the new research project RoKKa which is used to prove the viability of recovering raw materials from wastewater. This adds a crucial function to the scope of a conventional sewage treatment plant. Together with the operators of the sewage treatment plants in Erbach and Neu-Ulm, the project partners demonstrate the positive contribution towards climate protection…

The HUEHOCO GROUP Holding GmbH & Co. KG, a family-owned company from Wuppertal, North Rhine-Westphalia, has acquired a 5 percent stake in carbonauten GmbH.

Further utilisation of plant residues - 25/11/2021

Novel fibre composite made from hop fermentation residues

Biogas plants produce energy-rich gas by fermenting biomass. This process generates both liquid and solid fibrous and particulate fermentation residues. Researchers at the German Institutes of Textile and Fibre Research (DITF) have now managed to create a resistant and water-repellent fibre composite material from solid hop residues that can be used as a veneer to coat wood panels.

The Cluster of Excellence IntCDC of the University of Stuttgart presents the "Maison Fibre" at the International Architecture Exhibition Venice. The full-scale inhabitable installation is made from robotically produced, fibrous building elements.

The research project RUN (Rural Urban Nutrient Partnership) explores how waste might be used more efficiently as a resource. In this project, Veronika Fendel investigates how recyclable materials from biowaste and domestic wastewater can be fed back into the material cycle in the best possible way.
